Plastic may not always float where we expect it. The ocean’s surface might look clean in some places, but far beneath the waves, a different story is unfolding. 



In the southeastern Mediterranean, the deep seafloor is turning into a massive storage ground for plastic packaging, especially bags. A new study shows how this <a href="https://www.earth.com/news/large-retailers-are-replacing-plastic-bags-with-eco-friendly-paper-bags/">waste</a> ends up thousands of feet below the surface, and the answer isn’t as simple as trash just “sinking.”



<h2 class="wp-block-heading" id="h-plastic-in-the-deep-sea">Plastic in the deep sea</h2>



Plastic debris has entered every corner of the ocean, but previously, most of the research has concentrated on floating plastic or beach trash. That changed with this latest study, which took a closer look at what is occurring on the ocean floor. 



Scientists discovered that the Levant Basin - a deep section of the eastern <a href="https://www.earth.com/image/two-continents-meet-along-the-mediterranean-coastline/">Mediterranean</a> off the coasts of Israel, Egypt, and Turkey - is among the world's most contaminated deep-sea areas.



“We used trawls to survey the seafloor and we mainly found plastic bags and packaging that dominate the debris,” said Xing-Yu Li from the <a href="https://www.haifa.ac.il/?lang=en">University of Haifa</a>, the study’s lead author.



This raised a question: how does something so light - something meant to float - end up nearly a mile underwater?



<h2 class="wp-block-heading" id="h-a-forensic-approach-to-trash">A forensic approach to trash</h2>



To answer that, the team decided to treat each plastic item like a crime scene. Every piece of debris was carefully examined using a method called multi-marker analysis. 



This approach looks at everything about the plastic - size, shape, color, material, surface features, and even what kinds of things are stuck to it, like tar or <a href="https://www.earth.com/news/marine-organisms-may-adapt-to-climate-change-but-with-hidden-costs/">marine organisms</a>.



“In the multi-marker approach anything that is found on a piece of plastic is an evidence,” said Xing-yu. “We extracted as many evidence as possible from every piece of waste, more than many previous studies, to build a fuller, more detailed view of the bottom waste.”



Instead of just counting how much trash was found, this method helped researchers understand how it got there, why it sank, and where it might have come from.



<h2 class="wp-block-heading" id="h-why-some-plastic-doesn-t-sink">Why some plastic doesn’t sink</h2>



Most of the plastics found were <a href="https://www.earth.com/news/everyday-kitchen-tool-that-could-be-leaching-toxins-into-your-food-polypropylene-cutting-board/">polyethylene</a> - the same material used in grocery bags. Normally, this kind of plastic floats. But when additives like calcium carbonate (CaCO₃) are mixed in during manufacturing, the plastic becomes heavier. 



Those with CaCO₃ sank closer to the shore. Others, without these additives, drifted farther out before eventually settling on the seafloor.



The study also revealed that the deep basin at over 3,000 feet deep acts like a trap. Pressure and fine sediments help keep the plastic down. 



<a href="https://www.earth.com/news/biofilms-could-change-the-way-we-track-plastic-pollution/">Biofilms</a>, which are slimy layers formed by microbes, usually help weigh plastics down too, but they don’t grow well in this part of the sea. Instead, things like tar, sand, and tiny shells helped plastics stay put.



The scientists noted that these plastic films - while thin and lightweight - are ending up where they can do the most long-term damage. 



Even more troubling, the team found that some of this plastic could become buoyant again if disturbed, but because of how the deep sea works, that rarely happens. Once the plastic settles, it stays.



<h2 class="wp-block-heading" id="h-where-the-trash-is-coming-from">Where the trash is coming from</h2>



The plastic pollution isn’t only from local beaches. According to the research, land-based sources from Egypt, Israel, and Turkey are a big part of the problem. 



Shipping also plays a role, especially in deeper waters. Surprisingly, fishing was not a major contributor - possibly due to strict Israeli regulations.



For years, scientists noticed high levels of plastic at the seafloor, but they didn’t fully understand why. 



“For years in our monitoring reports we have reported a high concentration of plastic debris in this area. It was an unsolved mystery as we know that <a href="https://www.earth.com/news/ocean-floor-harbors-up-to-11-million-tons-of-plastic-debris/">plastic debris</a> should remain floating on the sea surface. Now we have a deep understanding of how it happens,” said Dr. Yael Segal from Israel Oceanographic and Limnological Research (IOLR). 



“The Eastern Mediterranean is the most polluted area in the world, and we must take action for the sake of the next generation.”



<h2 class="wp-block-heading" id="h-long-term-risks-to-marine-life">Long-term risks to marine life</h2>



<a href="https://www.earth.com/news/grapevines-could-offer-a-breakthrough-alternative-to-plastic-packaging/">Plastic packaging</a> is cheap, easy to produce, and used globally - but it doesn’t go away. It breaks into smaller pieces and can remain in the environment for hundreds of years. 



Deep-sea habitats are already fragile, and adding plastic into the mix could disrupt food webs, introduce toxins, and harm species that haven’t even been fully studied yet.



“As the head of the national monitoring program, I see firsthand how plastic pollution is impacting the entire sea environment: beaches, water, sea bottom, and even local turtle populations,” said Dr. Segal.



Professor Revital Bookman said that the discovery is fascinating in the worst possible way. 



"The eastern Mediterranean is quietly turning into a deep-sea landfill. Plastics that we use for only a few minutes are ending up trapped for centuries, threatening deep marine ecosystems we barely understand," noted Professor Bookman. 



<h2 class="wp-block-heading" id="h-what-needs-to-happen-next">What needs to happen next</h2>



According to the researchers, this study changes how we should think about ocean pollution. Plastic doesn’t just float around until it hits a beach. It travels far, interacts with other pollutants like tar, and ends up in hidden places. 



“This previously overlooked dynamic necessitates a broader perspective on pollution processes in marine environments,” said Professor Bookman. 



“Without systematic deep-sea accounting, we risk underestimating the true environmental footprint of plastic pollution and misallocating mitigation efforts by neglecting offshore and deep-sea sinks.”



To deal with this, the experts call for coordinated efforts across the region. Countries that share the sea need to work together on monitoring, cleanup, and prevention. 



Without a shared strategy, plastics will continue piling up, silently choking one of the planet’s most mysterious ecosystems.

In a report published in The Conversation, experts describe the potentially catastrophic crises faced by humanity, and our failure to acknowledge our interconnectedness with nature. 



The authors of the <a href="https://theconversation.com/humanitys-future-depends-on-our-ability-to-live-in-harmony-with-nature-233042" target="_blank" rel="noreferrer noopener">report</a> - Liette Vasseur, Anders Hayden and Mike Jones - note that our current mindset is focused on competition, growth and profit. This, they say, has been a key contributor to social and ecological crises



Humanity stands on the brink of a series of trials, each one potentially more devastating than the last. 



Our ongoing battles against inequality, poverty, inadequate food supplies, environmental turmoil, and loss of biodiversity suggest that we might have overstepped as hosts. 



<h2 class="wp-block-heading" id="h-can-nature-continue-to-sustain-life">Can nature continue to sustain life?</h2>



Our existence is woven into complex systems. A single tug at one thread resonates through the entire fabric. 



Societies often turn a blind eye to these <a href="https://www.earth.com/news/earth-day-2024-the-tide-may-finally-be-turning/" target="_blank" rel="noreferrer noopener">interconnections</a>, leading to a one-sided, exploitative relationship with nature. Our perceived superiority over other living beings, defined by race, gender, economic status, or species, fuels such exploitative tendencies.



Our growth-focused, competitive mindset has been a thorn in the side of both social and ecological welfare for years. 



What's truly chilling isn't the damage already done but the delicate state in which it leaves our environment. Have our actions pushed nature to a precipice, beyond which it can't sustain life?



<h2 class="wp-block-heading" id="h-straddling-the-fence">Straddling the fence</h2>



As we ponder over our collective survival and prosperity, addressing these <a href="https://www.earth.com/news/world-environment-day-2024-a-call-for-land-restoration/" target="_blank" rel="noreferrer noopener">interconnected</a> crises becomes non-negotiable. 



While initiatives like Earth for All and the United Nations' Pact for the Future offer some guidance, they fall short of the sweeping change we need. It's like trying to put out a forest fire with a water pistol.



<h2 class="wp-block-heading" id="h-sustainable-and-equitable-future">Sustainable and equitable future </h2>



What does this profound change entail? It's not merely about minor adjustments to existing systems; it's about revamping our interactions with the environment. 



In their report, the experts note that we must reciprocate what we take from nature. They emphasize that <a href="https://www.earth.com/news/tackling-the-dual-crises-of-climate-and-nature/" target="_blank" rel="noreferrer noopener">sustainable</a> and equitable well-being must be placed at the center of human societies.



The ability to lead good lives without overshooting our planet's boundaries is a tightrope walk we need to master. This balancing act requires an economic perspective that encourages living in harmony with nature, not against it.



<h2 class="wp-block-heading" id="h-daunting-yet-achievable">Daunting yet achievable</h2>



This transformation might seem like a Herculean task, but it's achievable. Communities from Puget Sound to Sumas First Nation serve as living proof of this possibility. The experts pointed out that in these communities, people are already living in ways that allow humans and ecosystems to flourish.



We, as adaptable creatures with the gift of foresight, have the capacity to transform systems through cooperation.



Our personal choices matter, but their influence magnifies when we unite for systemic changes in our communities, organizations, and the broader society. So, how about we pull together and accelerate this transition?



<h2 class="wp-block-heading" id="h-nature-friendly-sustainable-future">Nature-friendly sustainable future </h2>



Embracing a lifestyle intertwined with nature requires collaborative, equitable action, purposeful efforts, and communication across cultures. 



Let's start pondering over the ripple effects of our actions and contemplate both their immediate and long-term <a href="https://www.earth.com/news/bird-extinctions-shatter-the-harmonious-balance-of-nature/" target="_blank" rel="noreferrer noopener">repercussions</a>. It’s time we took the reins and crafted more fair and sustainable societal systems.



Addressing the plethora of problems we face requires a diverse toolkit of solutions, sourced from both formal knowledge, like scientific research, and traditional wisdom, such as Indigenous ecological knowledge. Imagine the swell of creativity we could unleash by blending these different knowledge systems.



This reformation is not just about changing our mindset; it’s also about reshaping our technological systems. 



Technology, often a tool for exploitation, bears <a href="https://www.earth.com/news/world-environment-day-the-critical-role-of-nature-in-human-well-being/" target="_blank" rel="noreferrer noopener">massive potential for positive changes</a>. With a systems thinking approach, we can steer technological innovations towards equity and sustainability.



<h2 class="wp-block-heading" id="h-a-circular-economy">A circular economy</h2>



Moving towards a circular economy is key to redesigning the relationship between humankind and the environment. 



Unlike the existing “use, produce, discard” model, the circular economy aims to minimize waste and maximize resource use through restorative and regenerative processes. This approach encourages a complete redesign of production processes to prioritize reuse and recycling materials. 



Not only does it reduce environmental harm, but it also creates economic opportunities and jobs, paving the way for a sustainable future within our planet’s resource limits.



<h2 class="wp-block-heading" id="h-education-key-to-change">Education: Key to change</h2>



Education stands as a powerful force in driving our transition to a more sustainable and equitable future. It’s the lantern that illuminates the interconnectedness of social, economic, and environmental systems, inspiring actionable change. 



By integrating sustainability principles into educational curricula, we can equip future generations with the knowledge and skills to address global challenges of nature. 



More than just enlightening, education can foster a sense of responsibility towards our planet, nurturing leaders who can champion innovation and sustainable policies.



<h2 class="wp-block-heading" id="h-nature-sustainability-and-our-future">Nature, sustainability, and our future</h2>



Significant changes loom over Earth's natural environments and societal systems. Our survival depends on our ability to plan for these challenges proactively. 



We need more than incremental changes to tackle these threats. "What is needed is radical transformation aimed at creating just and flourishing relationships between nature and humanity for the benefit of all current and future life on Earth," the experts concluded.

We must live in harmony with nature to create a sustainable future

In a report published in The Conversation, experts describe the...

Weather forecasting is a tricky business. We rely on it to plan our daily activities, prepare for natural disasters, and even to decide what to wear each day. Yet, despite advances in technology, we only get forecasts about 10 days into the future.



Why so? Small changes in atmospheric and surface conditions can trigger larger, unpredictable shifts in weather patterns. 



For example, consider the devastating Pacific Northwest heat wave in June 2021. Power lines melted, crops were destroyed, and hundreds of people lost their lives. A longer lead time on forecasts could have helped communities better prepare for the extreme heat.



<h2 class="wp-block-heading" id="h-adjoint-models-in-weather-forecasting">Adjoint models in weather forecasting</h2>



Weather scientists commonly turn to adjoint models to gauge how susceptible a forecast is to errors in initial conditions. Ever wondered how a slight tweak in <a href="https://www.earth.com/news/scorching-summer-of-2024-could-make-it-the-hottest-year-on-record/" target="_blank" rel="noreferrer noopener">temperature</a> or atmospheric water vapor can alter forecast results?



These models help answer that. They clarify the linkage between initial conditions and forecasted errors. Thus, scientists can adjust until they discover the set of initial conditions that yield the most accurate forecast.



However, there is a hitch. Running these models demands substantial financial and computing resources. And they can only measure sensitivities up to five days ahead.



<h2 class="wp-block-heading" id="h-deep-learning-in-weather-forecasting">Deep learning in weather forecasting</h2>



Researchers in the <a href="https://atmos.uw.edu" target="_blank" rel="noreferrer noopener">Department of Atmospheric Sciences</a> at the University of Washington have been exploring whether deep learning could offer an efficient and more precise method to determine the optimal set of initial conditions for a 10-day forecast.



To test their hypothesis, the experts modeled forecasts of the disastrous June 2021 Pacific Northwest heat wave. They utilized two different forecasting models: Google DeepMind's GraphCast model and Huawei Cloud's Pangu-Weather model.



The scientists wanted to check if the models operated similarly and how they stacked up against the <a href="https://www.earth.com/news/climate-records-shatter-2024-set-to-be-hottest-year-ever/" target="_blank" rel="noreferrer noopener">actual events of the heat wave</a>. To ensure unbiased results, they excluded the heat wave data from the dataset used to train the models.



<h2 class="wp-block-heading" id="h-evaluation-of-advanced-models">Evaluation of advanced models</h2>



The researchers carried out a rigorous comparison between the output of the GraphCast and Pangu-Weather models and actual meteorological data from the period of the June 2021 heat wave. 



They focused on the accuracy of temperature predictions, the models' ability to anticipate extreme conditions, and their computational efficiency. 



Preliminary results revealed that both models exhibited a high degree of accuracy, with Pangu-Weather displaying a slight edge in long-term temperature prediction. 



The advanced models showed promising potential in enhancing forecast accuracy and retiming their delivery, offering valuable insights for <a href="https://www.earth.com/news/auroras-and-severe-solar-storms-will-continue-through-tomorrow/" target="_blank" rel="noreferrer noopener">emergent situations</a> such as heat waves.



<h2 class="wp-block-heading" id="h-future-of-weather-forecasting">Future of weather forecasting</h2>



The implementation of deep learning models like GraphCast and Pangu-Weather marks a pivotal shift in the realm of meteorology, promising more accurate and timely forecasts. 



Yet, challenges persist, particularly in ensuring these models can process vast datasets in real-time scenarios and integrate seamlessly into existing forecasting frameworks. 



Additionally, there is a growing need for collaboration between meteorologists, data scientists, and policymakers to maximize the utility of these technological advancements. 



As research continues to unfold, these novel approaches hold the potential to revolutionize weather forecasting, resulting in better community preparedness and resilience against climate anomalies.



<h2 class="wp-block-heading" id="h-scaling-deep-learning">Scaling deep learning</h2>



Scaling deep learning approaches for global weather forecasts requires a comprehensive strategy to manage data heterogeneity, computational intensity, and energy consumption. 



The vast and varied data sources - from satellite imagery to oceanic sensor readings - demand that models harmonize inputs with differing resolutions and formats.



The computational power needed to handle such voluminous and diverse datasets is substantial, raising concerns about environmental impact due to energy-intensive processes. 



Consequently, researchers are exploring energy-efficient algorithms and innovative hardware solutions to mitigate these challenges. Additionally, there is a critical need for robust validation frameworks to ensure these models' generalizability across diverse climatic regions and conditions.



<h2 class="wp-block-heading" id="h-ai-driven-weather-forecasting">AI-driven weather forecasting</h2>



The integration of artificial intelligence in weather forecasting introduces several ethical considerations that warrant careful examination. 



Predominantly, the question of data privacy emerges, as intricate datasets often include sensitive geolocation information. Additionally, there is an inherent risk of algorithmic bias, where disparities in data collection can skew predictions, disproportionately affecting certain populations or regions. 



Transparency and accountability in AI decision-making processes are imperative to ensure equitable access to advanced forecasting <a href="https://www.earth.com/news/2024-is-expected-to-exceed-the-1-5c-warming-limit/" target="_blank" rel="noreferrer noopener">technologies</a>. 



<h2 class="wp-block-heading" id="h-reduction-in-forecast-errors">Reduction in forecast errors</h2>



The results were nothing short of astonishing. Employing deep learning to pinpoint optimal initial conditions led to a massive 94% reduction in 10-day forecast errors in the GraphCast model.



A similar drop in errors was noted when the method was applied to the Pangu-Weather model. Remarkably, the new technique improved forecasts as much as 23 days in advance.



So, do we stand at the threshold of a new era in weather forecasting? Can we look forward to forecasts that are not just more accurate, but also offer longer lead times? If the findings are any indication, this might not be too far off.



The study is published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024GL110651" target="_blank" rel="noreferrer noopener">Geophysical Research Letters</a>.

New era in forecasting: AI will improve extreme weather warnings

Weather forecasting is a tricky business. We rely on it...

Did you know our oceans naturally contain tiny quantities of toxic metal elements like lead, mercury, arsenic, and cadmium? It sounds a bit concerning. But these trace elements typically aren’t an issue. 



However, human activities such as industry and agriculture have been contributing heftier amounts.



To make matters worse, a new study has found climate change already has an impact on how these elements are distributed and accumulated in our seas. As we move forward, this could have significant implications.



<h2 class="wp-block-heading" id="h-understanding-changes-in-the-ocean">Understanding changes in the ocean</h2>



We are well-versed in the impacts of climate change on our oceans: warming temperatures, growing acidity, and loss of oxygen. The newest twist in the tale however is the way climate change affects <a href="https://www.earth.com/news/is-it-still-possible-to-save-the-ocean-from-plastic-pollution/" target="_blank" rel="noreferrer noopener">contaminants in ou</a><a href="https://www.earth.com/news/is-it-still-possible-to-save-the-ocean-from-plastic-pollution/">r seas</a>.



The research was led by Dr. Rebecca Zitoun, a marine chemist at <a href="https://www.geomar.de/en/" target="_blank" rel="noreferrer noopener">GEOMAR</a> Helmholtz Center for Ocean Research Kiel, and Dr. Saša Marcinek from the <a href="https://www.irb.hr/eng/" target="_blank" rel="noreferrer noopener">Ruđer Bošković Institute</a> in Zagreb.



Lead, mercury, cadmium, and other metals don't just enter our <a href="https://www.earth.com/news/ocean-plastic-pollution-has-become-a-global-crisis/" target="_blank" rel="noreferrer noopener">oceans</a> through industrial or fossil fuel burning activities. 



As it turns out, natural sources of these elements are undergoing changes due to climate factors such as rising sea levels, rivers overflowing, or drying up, and melting sea ice and glaciers. The result? Increased flow and mobilization of contaminants.



<h2 class="wp-block-heading" id="h-metal-contaminants-in-the-ocean">Metal contaminants in the ocean</h2>



The research is the product of a working group of the UN Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (<a href="http://www.gesamp.org" target="_blank" rel="noreferrer noopener">GESAMP</a>), with a focus on metal contaminants in the ocean. 



Dr. Sylvia Sander, professor of marine mineral resources at GEOMAR and former head of the Marine Environmental Studies Laboratories at IAEA in Monaco, initiated this working group. German contributor Christoph Völker from the AWI is another member of this group.



"Our working group has focused on the effects of climate change and greenhouse gases on <a href="https://www.earth.com/news/hotspots-of-microplastic-pollution-found-in-the-north-sea/" target="_blank" rel="noreferrer noopener">contaminants</a> in the ocean," explained Dr. Sander.



This rise is mainly due to melting glaciers, thawing permafrost, and coastal erosion. Such an increase in mercury levels poses a significant risk to communities dependent on traditional fishing, as mercury accumulates in the food chain.



<h2 class="wp-block-heading" id="h-the-contribution-of-human-activities">The contribution of human activities </h2>



"Human activities have increased the global flow of toxic metals such as lead by tenfold and mercury by three to seven times compared to pre-industrial levels," said Dr. Sander.



"Toxic elements like silver are increasingly detectable in&nbsp;coastal waters, originating from coal combustion and the growing use of silver nanoparticles in antibacterial products."



It's not just these elements, but even silver is increasingly detectable in coastal waters, thanks to coal combustion and the growing use of silver nanoparticles in antibacterial products.



The proliferation of plastics and shipping have further contributed to this issue. They can bind heavy metals such as copper, zinc, and lead, which can then enter the food chain. With <a href="https://www.earth.com/news/ocean-diversity-takes-a-hard-hit-near-offshore-platforms/" target="_blank" rel="noreferrer noopener">increasing exploitation of the oceans</a>, the human contribution of these heavy metals could rise even further.



<h2 class="wp-block-heading" id="h-changing-climate-and-metals">Changing climate and metals</h2>



Climate changes, like warming sea temperatures, ocean acidification, and oxygen depletion, impact trace elements in a variety of ways.



For instance, water temperatures directly influence the bioavailability and uptake of trace elements like mercury in marine organisms. 



With higher temperatures, metabolism increases, oxygen solubility reduces, and gill ventilation improves, leading to more metals entering organisms and accumulating in their bodies.



Additionally, as our oceans absorb more human-emitted CO2, their pH levels drop, thus increasing the solubility and bioavailability of metals like copper, zinc, and iron. 



This can be particularly damaging with copper, which is highly toxic to many marine organisms at increased concentrations.



<h2 class="wp-block-heading" id="h-changes-in-ocean-contaminants">Changes in ocean contaminants </h2>



Human activities have a two-pronged effect on the amount of contaminants in our coastal regions. There is the direct impact where we release pollutants into the environment, and then there is the indirect effect of climate change on natural sources of these elements.



What's concerning is that there is a significant lack of data on how climate change influences contaminants in the ocean. 



The working group argues that we need more research into new and under-studied contaminants. They also stress on the need for better models, as well as updating legislation that controls the impact of contaminants in the seas.



<h2 class="wp-block-heading" id="h-emerging-challenges">Emerging challenges</h2>



The dual threat of climate change and environmental contamination presents a formidable challenge requiring innovative solutions and collaborative strategies. 



One burgeoning area of research is the development of advanced models that provide comprehensive insights into the interaction between climate variables and <a href="https://www.earth.com/news/major-plastic-pollution-lurks-beneath-the-surface-of-rivers/" target="_blank" rel="noreferrer noopener">contaminant behavior in marine eco</a><a href="https://www.earth.com/news/major-plastic-pollution-lurks-beneath-the-surface-of-rivers/">systems. </a>



Such models would enable scientists to predict shifts in contaminant distribution and, more importantly, devise mitigation strategies that prioritize environmental and human health.



In addition, the integration of satellite technology and big data analytics offers unprecedented opportunities to enhance our understanding and monitoring of marine pollution on a global scale.



<h2 class="wp-block-heading" id="h-saving-oceans-from-toxic-metals">Saving oceans from toxic metals</h2>



"To better understand the impacts on ecosystems and human health, we need to close knowledge gaps on the interactions between pollutants and climate change and develop standardized methods that provide globally comparable data," said Dr. Zitoun.



While there is much we still need to learn, the importance of strengthening marine protection and developing sustainable solutions for vulnerable coastal areas cannot be overstated. Climate change and pollution are complex issues, but addressing them is essential for preserving our oceans.



The study is published in the journal <a href="https://www.nature.com/articles/s43247-024-01679-y" target="_blank" rel="noreferrer noopener">Communications Earth &amp; Environment</a>.

Climate change makes metals in the ocean more toxic

Did you know our oceans naturally contain tiny quantities of...

An unexpected and obscure phenomenon in the Arctic could dramatically accelerate climate change: the weathering of rocks.



This natural process in the Canadian Arctic could potentially trigger a feedback loop, accelerating the release of carbon dioxide (CO2) into the atmosphere as global temperatures continue to rise.



<h2 class="wp-block-heading" id="h-arctic-rock-weathering">Arctic rock weathering</h2>



<a href="https://www.earth.com/news/natural-rock-weathering-is-a-co2-source-comparable-to-volcanoes/" target="_blank" rel="noreferrer noopener">Rock weathering</a> is a process where certain minerals and rocks react with oxygen in the atmosphere. This results in a series of chemical reactions that ultimately release CO2.



As an example, the weathering of sulfide minerals - like fool's gold - produces an acid that forces <a href="https://www.earth.com/news/met-office-2024-co2-levels-will-surpass-the-point-of-no-return/" target="_blank" rel="noreferrer noopener">CO2</a> out of other rock minerals.



The scary part? This largely overlooked weathering process is increasing in the Arctic because of rising temperatures.



The Arctic is warming nearly four times faster than the global average, which means we urgently need to understand the potential contribution of CO2 emissions from rocks.



Until recently, our knowledge about the response of rock weathering to changing temperatures. as well as the amount of additional CO2 that could be released. was quite limited.



<h2 class="wp-block-heading" id="h-alarming-acceleration-of-arctic-weathering">Alarming acceleration of Arctic weathering</h2>



A recent study has provided some fascinating insights. The investigation focused on 23 sites across the Mackenzie River Basin, Canada's largest river system.



The researchers examined the sensitivity of sulfide weathering - the process behind these CO2 emissions - to <a href="https://www.earth.com/news/arctic-biodiversity-will-get-a-boost-from-rising-temperatures/" target="_blank" rel="noreferrer noopener">rising temperatures</a>. They used records of sulfate, a product of sulfide weathering, to trace the speed of the process.



The findings were alarming. Over the past 60 years, from 1960 to 2020, as temperatures increased by 2.3°C, sulfide weathering increased by 45 percent. This suggests that the CO2 released could trigger a feedback loop, accelerating warming in the Arctic.



<h2 class="wp-block-heading" id="h-dramatic-increases-in-sulfide-oxidation">Dramatic increases in sulfide oxidation </h2>



Drawing from past river records, the researchers forecasted that by 2100, carbon dioxide released from the Mackenzie River Basin could double to 3 billion kg/year under a moderate emission scenario.



To put this into perspective, this would be equivalent to half the total annual emissions from Canada's domestic aviation sector.



"We see dramatic increases in sulfide oxidation across the Mackenzie with even moderate warming," said study co-author Dr. Ella Walsh.



"Until now, the temperature sensitivity of CO2 release from sulfide rocks and its main drivers were unknown over large areas and timescales.”



What's more, not all parts of the river catchment were affected equally. Weathering was much more sensitive to temperature in rocky mountainous areas and those covered with <a href="https://www.earth.com/news/abrupt-permafrost-thaw-releases-more-co2-than-expected/" target="_blank" rel="noreferrer noopener">permafrost</a>. 



Conversely, regions blanketed with peatland showed lower increases in sulfide oxidation with warmth because the peat protects the bedrock.



<h2 class="wp-block-heading" id="h-sulfide-weathering-and-climate-models">Sulfide weathering and climate models</h2>



The implications of this study, conducted by experts in the Department of Earth Sciences at the <a href="https://www.ox.ac.uk/" target="_blank" rel="noreferrer noopener">University of Oxford</a>, are far-reaching beyond the Mackenzie River Basin.



Similar environments across the Arctic - characterized by rock types, high proportions of exposed bedrock, and extensive permanently frozen ground - could also see rapid increases in sulfide weathering.



According to the researchers, this highlights the urgent need to consider sulfide weathering in large-scale emission models, which are extremely useful for making <a href="https://www.earth.com/news/climate-experts-predict-global-warming-will-far-exceed-paris-goals/" target="_blank" rel="noreferrer noopener">climate change predictions</a>. 



As we continue to grapple with the impacts of climate change, understanding these lesser-known factors and their potential to accelerate the process is more important than ever.



<h2 class="wp-block-heading" id="h-building-ecosystem-resilience-in-the-arctic">Building ecosystem resilience in the Arctic </h2>



Given the potentially widespread effects of sulfide weathering, leveraging the natural resilience of Arctic ecosystems may provide a partial solution. 



Arctic regions contain unique biomes, like tundra and peatland, which can act as natural carbon buffers. These ecosystems not only absorb CO2 but also moderate temperatures and shield underlying bedrock from rapid warming. 



Expanding conservation efforts to protect these areas could help slow down the feedback loop triggered by sulfide weathering.



Addressing the issue also requires international cooperation. The Arctic spans multiple countries, each facing unique challenges as climate change accelerates. 



Collaborative research initiatives, involving Arctic nations and global scientific organizations, could help standardize monitoring practices and improve data-sharing on sulfide weathering. 



By pooling resources and expertise, these partnerships can enhance predictive models, leading to more effective climate policies.



Furthermore, an increased focus on reducing global greenhouse gas emissions remains essential. While the impact of sulfide weathering is significant, its long-term consequences will depend on the overall trajectory of global warming.

Rock weathering drives further warming in the Arctic

An unexpected and obscure phenomenon in the Arctic could dramatically...

The potential role of climate change in escalating harmful emissions worldwide has expanded into the Amazon rainforest.



Climate extremes predicted for the Amazon region, such as excessive rain and prolonged drought, could significantly impact the emission and uptake of methane, a potent greenhouse gas.



<h2 class="wp-block-heading" id="h-methane-emissions-from-amazon-floodplains">Methane emissions from Amazon floodplains</h2>



For half the year, steady rainfall and rising river levels result in over 800,000 square kilometers of Amazon rainforest's floodplains being submerged. These swaths of land comprise 20 percent of the total <a href="https://www.earth.com/news/amazon-animals-will-suffer-as-the-rainforest-turns-into-savanna/" target="_blank" rel="noreferrer noopener">rainforest</a> area.



The submerged organic matter, broken down by microbial communities, increases methane production. Shockingly, Amazon's floodplains contribute almost a third of methane emissions from global wetlands. 



In stark contrast, the forested regions of higher ground, or "upland forests," operate as methane sinks. They make an invaluable contribution to mitigating greenhouse gas emissions by removing methane from the atmosphere. 



<h2 class="wp-block-heading" id="h-functionality-of-soil-microbial-communities">Functionality of soil microbial communities </h2>



The research, led by experts at the University of São Paulo (<a href="https://www5.usp.br/" target="_blank" rel="noreferrer noopener">USP</a>) in Brazil, is published in the journal <a href="https://environmentalmicrobiome.biomedcentral.com/articles/10.1186/s40793-024-00596-z" target="_blank" rel="noreferrer noopener">Environmental Microbiome</a>.



"Seasonal floodplains in the Amazon basin are important sources of methane (CH4), while upland forests are known for their sink capacity," explained the study authors.



"Climate change effects, including shifts in rainfall patterns and rising temperatures, may alter the functionality of soil microbial communities, leading to uncertain changes in CH4&nbsp;cycling dynamics."&nbsp;



The findings highlight the urgent need for conservation and management plans that account for Amazon <a href="https://www.earth.com/news/rising-methane-emissions-threaten-earths-habitability/" target="_blank" rel="noreferrer noopener">methane</a> emissions.



<h2 class="wp-block-heading" id="h-methane-flow-in-the-amazon">Methane flow in the Amazon</h2>



Júlia Brandão Gontijo, the study's first author, is a postdoctoral researcher at the University of California, Davis.



"Although it’s already been shown that factors such as air temperature and seasonal flooding can influence the composition of microbial communities and hence affect the flow of methane in these environments, what should we expect in the context of climate change and the projected alterations in rainfall and temperature patterns, with more intense extremes?" said&nbsp;Brandão Gontijo.



The research team designed a 30-day experiment to find answers, testing soil samples from two floodplains and an upland forest in two municipalities located in the west of Pará state.



"To investigate the microbial feedback under climate change scenarios, we performed a microcosm experiment," noted the researchers.



<h2 class="wp-block-heading" id="h-the-amazon-s-methane-balance">The Amazon's methane balance</h2>



The samples were subjected to extreme temperatures and humidity. The findings revealed that the number of methane-producing microorganisms increased in both floodplains, potentially indicating future <a href="https://www.earth.com/news/melting-arctic-glaciers-are-releasing-a-new-source-of-potent-methane-emissions/" target="_blank" rel="noreferrer noopener">methane</a> emission concerns.



Additionally, methane consumption by the upland forest soil plummeted by 70 percent during warm and dry conditions. 



On the contrary, methane production surged significantly during periods of heavy rain. Since the soil is not routinely exposed to extreme humidity, the research shed light on its responsiveness to these conditions. This scenario is particularly concerning.



<h2 class="wp-block-heading" id="h-implications-of-the-study">Implications of the study</h2>



"Taken together, our data indicate that CH4&nbsp;cycle dynamics and microbial communities in Amazonian floodplain and upland forest soils may respond differently to climate change effects," wrote the study authors. 



"We also highlight the potential role of CH4&nbsp;oxidation pathways in mitigating CH4&nbsp;emissions in Amazonian floodplains."



The floodplain microbiome could adapt to climate change, while the upland forest microbiome appears sensitive to its effects. This potential disparity could seriously disrupt the balance of greenhouse gas emissions in the Amazon region in the future. 



Considering the enormous significance of the Amazon rainforest biome on a global scale, this could pose a severe problem.



<h2 class="wp-block-heading" id="h-complex-interactions-in-the-amazon">Complex interactions in the Amazon</h2>



The study also revealed a glimmer of hope - methanotrophic microorganisms. These methane-consuming life forms use methane as an energy source, giving them the potential to offset an increase in <a href="https://www.earth.com/news/rapid-reductions-in-methane-emissions-are-possible/" target="_blank" rel="noreferrer noopener">methane emissions</a>.



This is just the beginning. The team is planning to conduct field experiments and laboratory trials with these microorganisms to deepen their understanding of methane cycling dynamics. 



The experts noted that the findings emphasize the importance of considering both environmental factors when assessing the dynamics of methane&nbsp;in these distinct ecosystems.



This contributes to our understanding of the complex interactions between climate, hydrology, and microbial processes in the Amazon region, concluded the researchers.

Climate extremes will boost methane emissions in the Amazon

The potential role of climate change in escalating harmful emissions...

According to widely accepted models, a dramatic cooling event and significant drop in sea levels roughly 34 million years ago, during the Eocene-Oligocene transition, should have resulted in widespread erosion across the continents. This would have deposited vast amounts of sandy material onto the ocean floor.&nbsp;



The Eocene-Oligocene transition marked one of the most extreme climate shifts since the extinction of the dinosaurs, transforming Earth’s climate from a “greenhouse” into an “icehouse” one. 



Yet, a new review from <a href="https://www.stanford.edu/" target="_blank" rel="noreferrer noopener">Stanford University</a> reveals a surprising contradiction: across the margins of all seven continents, there is little to no <a href="https://www.earth.com/news/ancient-sediments-predict-future-stressors-for-cold-water-corals/" target="_blank" rel="noreferrer noopener">sediment</a> from this period to be found.



<h2 class="wp-block-heading" id="h-climate-clues-in-the-geologic-record-nbsp">Climate clues in the geologic record&nbsp;</h2>



This unexpected finding, published in <a href="https://www.sciencedirect.com/science/article/abs/pii/S0012825224002393" target="_blank" rel="noreferrer noopener">Earth-Science Reviews</a>, uncovers a puzzling global gap in the geologic record. 



“The results have left us wondering, ‘where did all the sediment go?’” said senior author Stephan Graham, a professor in the Stanford Doerr School of Sustainability.&nbsp;



“Answering that question will help us get a better fundamental understanding about the functioning of sedimentary systems and how climatic changes imprint on the deep marine sedimentary record.”



<h2 class="wp-block-heading" id="h-environmental-effects-of-climate-shifts">Environmental effects of climate shifts</h2>



The discovery challenges existing models of sediment deposition and erosion and offers new insights into the global environmental effects of significant climate shifts.&nbsp;



The findings may also provide a clearer understanding of how today’s <a href="https://www.earth.com/news/climate-change-is-happening-too-fast-for-some-species-to-adapt/" target="_blank" rel="noreferrer noopener">rapid climate change</a> might reshape Earth’s surface.



“For the first time, we’ve taken a global look at an understudied response of the planet’s largest sediment mass-movement systems during the extreme transition of the Eocene-Oligocene,” explained lead author Zack Burton, now an assistant professor of Earth sciences at Montana State University.&nbsp;



The Eocene-Oligocene transition was a period of profound <a href="https://www.earth.com/news/global-cooling-wont-be-a-quick-fix-for-the-state-of-our-oceans/" target="_blank" rel="noreferrer noopener">planetary cooling</a>. Large ice sheets formed in Antarctica, which had previously been ice-free, global sea levels fell sharply, and there were significant die-offs among both marine and terrestrial species. 



Before this period, Earth had experienced some of the highest temperatures and sea levels since the age of the dinosaurs, according to climate proxy records. Burton and his colleagues initially set out to investigate the effects of these early Eocene warm conditions on deep-sea depositional systems. 



<h2 class="wp-block-heading" id="h-detailed-analysis-of-the-climate-shift">Detailed analysis of the climate shift</h2>



In a 2023 study published in <a href="https://sustainability.stanford.edu/news/climate-patterns-shape-sand-deposits-deep-sea" target="_blank" rel="noreferrer noopener">Nature Scientific Reports</a>, they found evidence of abundant sand-rich deposits along Earth's continental margins, which they attributed to intensified weather conditions that increased <a href="https://www.earth.com/news/changes-in-climate-and-land-use-could-lead-to-catastrophic-levels-of-soil-erosion/" target="_blank" rel="noreferrer noopener">erosion</a> from land. 



The team then decided to extend their study to cover the later Eocene and early Oligocene, during which Earth rapidly cooled and entered an “icehouse” climate.



To do this, the researchers conducted a meticulous review of hundreds of scientific papers spanning over a century. They analyzed studies that documented ancient sediment, often buried several kilometers beneath the ocean floor.&nbsp;



This comprehensive review included findings from offshore oil and gas drilling, onshore rock outcrops, and seismic data interpretations. Altogether, the study examined over 100 geographical sites worldwide, providing a detailed look at the geologic records from the margins of all continents.



As the team combed through the collected data, they found a baffling absence of sand-rich sediments from the Eocene-Oligocene transition.&nbsp;



<h2 class="wp-block-heading" id="h-missing-sediments-in-the-geologic-record-nbsp">Missing sediments in the geologic record&nbsp;</h2>



“We didn’t see abundant sand-rich deposition, as in our study of warm climates of the early Eocene,” Burton said.&nbsp;



“Instead, we saw that prominent, widespread erosional unconformities - in other words, gaps in the rock record - had developed during the extreme climatic cooling and oceanographic change of the Eocene-Oligocene.”



The researchers propose several theories to explain the missing sediments. One idea is that strong ocean bottom currents, driven by changes in temperature and salinity triggered by the climate shift, could have scoured the ocean floor, eroding sediments that flowed off the continents.&nbsp;



Another possibility is that the rapid drop in sea levels exposed continental shelves, allowing sediments to bypass nearer sedimentary basins and be deposited much farther out on the ocean's abyssal plains. Additionally, glacial erosion around Antarctica may have played a role in redistributing sediments.



<h2 class="wp-block-heading" id="h-profound-changes-across-land-and-sea">Profound changes across land and sea</h2>



These processes appear to have operated across the globe, suggesting that the sedimentary record was influenced by global climatic controls. The researchers believe that this global impact points to the profound climatic changes felt not only on land but also in the deepest oceanic basins.



The study’s findings provide a valuable perspective on how Earth's surface can respond to significant climate shifts.&nbsp;



The Eocene-Oligocene transition offers a window into the large-scale environmental transformations that can result from rapid climate change, something that is highly relevant to understanding today’s human-driven climate shifts.



<h2 class="wp-block-heading" id="h-radical-changes-with-rapid-climate-change-nbsp">Radical changes with rapid climate change&nbsp;</h2>



Although the current climate change crisis is smaller in overall magnitude compared to the Eocene-Oligocene transition, it is unfolding at a much faster pace.&nbsp;



The researchers believe that studying these past events can help scientists better predict the kinds of drastic changes that may occur as Earth’s climate continues to change rapidly.



“Our findings can help inform us of the kinds of radical changes that can happen on the Earth’s surface in the face of rapid climate change,” Graham said. “The geologic past informs the present, and particularly the future.”



By reexamining past climatic events and sedimentary responses, scientists hope to gain insights that could guide our understanding of the challenges posed by modern climate change, and potentially help mitigate its effects on Earth's ecosystems and surface environments.

Ancient climate shift sheds light on future global warming

According to widely accepted models, a dramatic cooling event and...

We are surrounded by a world that is increasingly plastic. It's in our homes, cars, offices, and even our food. The recent discovery that microplastic pollution has infiltrated the life of even newborn creatures strikes a chord of concern.



These remnants of our plastic usage, tiny bits smaller than a grain of sand, have made their way into every nook and cranny of our ecosystem, and of our bodies. 



This was the critical point of a recent study published in Science of the Total Environment, led by a team from <a href="https://rutgershealth.org/" target="_blank" rel="noreferrer noopener">Rutgers Health</a>.



<h2 class="wp-block-heading" id="h-what-are-micro-and-nanoplastics">What are micro- and nanoplastics?</h2>



These invisible bad guys that we're talking about are known as micro- and <a href="https://www.earth.com/news/plants-could-help-remove-nanoplastics-from-the-environment/" target="_blank" rel="noreferrer noopener">nanoplastic particles</a> (MNPs). 



Microplastics are fragments smaller than 5 millimeters, about the size of a sesame seed or smaller. Nanoplastics, even tinier, measure less than 1 micrometer -- much smaller than the width of a human hair. 



Ever wondered where they come from?



These plastics originate from larger plastic items breaking down over time or are intentionally manufactured in small sizes for use in products like cosmetics and cleaning supplies.



Once released, micro- and nanoplastics can make their way into oceans, rivers, and even the air we breathe. 



<a href="https://www.earth.com/news/microplastic-pollution-found-in-every-aquatic-species-tested/" target="_blank" rel="noreferrer noopener">Marine animals</a> often mistake them for food, which can harm their health and introduce plastics into the food chain. 



Since these plastics are so small, they’re challenging to remove and can persist in the environment for centuries.



But, How do they get <a href="https://www.earth.com/news/human-microplastic-ingestion-levels-mapped-across-109-countries/" target="_blank" rel="noreferrer noopener">into our bodies</a>? The answer is simple: inhalation, absorption and through our diet.



<h2 class="wp-block-heading" id="h-microplastic-pollution-entering-newborns">Microplastic pollution entering newborns</h2>



It's common knowledge that these pollutants can cross the sanctuary of the womb and settle down in fetal tissues. However, the big question has always been whether these <a href="https://www.earth.com/news/microplastics-are-infiltrating-the-human-body-even-the-brain/" target="_blank" rel="noreferrer noopener">particles stick around post-birth</a>. 



The Rutgers Health team, in their study, have found that they indeed do, at least in the case of rats. This discovery could potentially have significant implications for human health.



“Nobody wants plastic in their liver,” said <a href="https://pharmacy.rutgers.edu/directory/stapleton-phoebe/" target="_blank" rel="noreferrer noopener">Phoebe A. Stapleton</a>, an associate professor of pharmacology and toxicology at the <a href="https://pharmacy.rutgers.edu/" target="_blank" rel="noreferrer noopener">Rutgers Ernest Mario School of Pharmacy</a>, and the study’s senior author. 



“Now that we know it’s there -- as well as in other organs -- the next step is to understand why and what that means.”



<h2 class="wp-block-heading" id="h-proof-in-the-offspring">Proof in the offspring</h2>



To evaluate the persistence of MNPs after birth, Stapleton and her team exposed six pregnant rats to aerosolized food-grade plastic powder for ten days. 



The chosen subjects were rodents, as they, like humans, have a hemochorial placenta, meaning no direct blood contact between mother and fetus during circulation.



Two weeks post-birth, two baby rats were tested for MNP exposure, and the results were enlightening: the same type of plastic that their mothers inhaled was found in these infant rodents' lungs, liver, and even brain tissue.



<h2 class="wp-block-heading" id="h-growing-concerns-over-microplastic-pollution">Growing concerns over microplastic pollution</h2>



These findings provide another piece to the puzzle on the potential hazards posed by micro- and nanoplastics. 



Ever seen plastic in your food, or in farmland, seawater, or snow? Such omnipresent particles might lead to health issues like cancer, inflammation, and <a href="https://www.earth.com/news/microplastics-found-in-every-semen-sample-tested/" target="_blank" rel="noreferrer noopener">tissue degeneration</a>.



Stapleton hopes that the results will propel a sense of urgency among decision-makers for more research funding. 



"Without answers, we can't have a policy change," she said. With increased understanding, regulators can better protect public health and perhaps introduce more stringent regulations on plastic usage.



<h2 class="wp-block-heading" id="h-complex-consequences">Complex consequences</h2>



“These results raise concerns for the toxicological impacts associated with MNPs exposure, maternal-fetal health, and systemic MNPs particle deposition,” the researchers wrote. The presence of micro- and nanoplastics has not escaped the oceans' depths, where <a href="https://www.earth.com/news/hotspots-of-microplastic-pollution-found-in-the-north-sea/" target="_blank" rel="noreferrer noopener">marine life is unwittingly affected</a> by these pervasive particles. 



As these plastics break down into smaller fragments, they are ingested by a wide range of aquatic organisms, from plankton to larger fish. 



This ingestion can lead to physical blockages, starvation, and even the absorption of toxic chemicals associated with the plastics themselves.



The research increasingly suggests that micro- and nanoplastics can disrupt the reproductive systems of marine species and contribute to systemic toxicity, paving the way for alterations in <a href="https://www.earth.com/news/microplastic-pollution-antarctica-much-worse-than-previously-believed/" target="_blank" rel="noreferrer noopener">entire ecosystems</a>.



Addressing this global issue demands urgent attention to both reduce plastic pollution and mitigate its harmful impacts on biodiversity.



<h2 class="wp-block-heading" id="h-future-of-microplastic-pollution">Future of microplastic pollution</h2>



"Eventually, the persistence of these materials in <a href="https://www.earth.com/news/microplastics-discovered-in-every-human-placenta-tested-after-birth/" target="_blank" rel="noreferrer noopener">human tissue</a> could lead to greater regulation," Stapleton said.



"While plastics have undoubtedly improved consumer products, too little is known about their long-term health impacts. As researchers fill knowledge gaps, regulators will be better equipped to protect public health," she added.



“I don't think we'll ever get rid of plastics altogether,” Stapleton remarked. “They’re too important for modern life. But I do think we might get to a point where we’ll have some policies to indicate which ones are less toxic than others.”



To sum it all up, while plastics have undoubtedly made our lives easier, it's high time we weigh the conveniences against the long-term health implications due to its pollution.



The study is published in the journal <a href="https://www.sciencedirect.com/science/article/pii/S0048969724055001?via%3Dihub" target="_blank" rel="noreferrer noopener">Science of The Total Environment</a>.

Microplastic pollution is everywhere, even in newborns, and it's getting worse

We are surrounded by a world that is increasingly plastic....

Temperature is a key factor in determining where species can thrive and whether they are at risk from climate change.&nbsp;



While much research has focused on how heat tolerance affects survival, less attention has been paid to how thermal traits influence reproduction, which is directly connected to extinction risk.&nbsp;



Now, a team of researchers in the United States has explored whether male dragonflies with dark wing coloration, used as a sexual signal during mating, are more resistant to heat.&nbsp;



<h2 class="wp-block-heading" id="h-reproductive-traits-and-heat-tolerance-nbsp">Reproductive traits and heat tolerance&nbsp;</h2>



The findings, published in the journal <a href="http://dx.doi.org/10.3389/fetho.2024.1447637" target="_blank" rel="noreferrer noopener">Frontiers in Ethology</a>, provide new insights into the link between reproductive traits and heat tolerance.



“We show that dragonfly species that have evolved dark breeding coloration on their wings have also evolved the ability to tolerate high temperatures,” said lead author Noah Leith, a biologist at the University of Pittsburgh.&nbsp;



“This finding paves the way for a whole new field of research exploring interactions between thermal traits and sexual signals.”



<h2 class="wp-block-heading" id="h-wing-coloration-and-mate-selection">Wing coloration and mate selection</h2>



In many animals, including <a href="https://www.earth.com/news/dragonflies-hunt-perfectly-even-in-extreme-temperatures/" target="_blank" rel="noreferrer noopener">dragonflies</a>, sexual signals like wing coloration play an important role in attracting mates, identifying species for reproduction, and deciding when to retreat from mating contests. However, these dark wing ornaments come with a downside.&nbsp;



Dark colors absorb more heat, raising the dragonflies' body temperature, which can result in physiological stress or cause males to abandon their reproductive territories.



“We see time and time again that animals will put their lives on the line to reproduce, even if it means encountering potentially lethal temperatures,” Leith said.



<h2 class="wp-block-heading" id="h-wing-coloration-and-heat-stress">Wing coloration and heat stress</h2>



To investigate, the researchers analyzed 14 species of dragonflies living in tropical climates and five species from temperate regions.&nbsp;



They discovered that species with dark, heat-absorbing wing coloration had evolved to withstand higher <a href="https://www.earth.com/news/at-what-point-does-heat-stress-become-dangerous/" target="_blank" rel="noreferrer noopener">heat stress</a> before reaching their critical thermal limits.&nbsp;



“This enhanced ability to tolerate high body temperatures is likely crucial for shaping how dragonflies may respond to the changing climates of the future,” Leith explained.



<h2 class="wp-block-heading" id="h-dark-wings-increase-body-temperature">Dark wings increase body temperature</h2>



The researchers found that dark wing ornaments can increase a dragonfly's body temperature by 1°C to 2°C, which is approximately the same as the increase in thermal tolerance observed in species with dark wing patterns.&nbsp;



The tropical species Tauriphila argo, also known as the arch-tipped glider, was found to have the highest heat tolerance among the species studied.&nbsp;



This dragonfly has very dark wing patches near its core body, which absorbs more heat. Overall, the pattern of co-evolution between dark coloration and heat tolerance was even stronger in tropical species, where high temperatures are a constant challenge.



<h2 class="wp-block-heading" id="h-evolution-of-heat-tolerance-nbsp">Evolution of heat tolerance&nbsp;</h2>



Previous research has shown that rising global temperatures are causing some dragonfly species to evolve with less wing coloration. 



However, the new findings suggest that even if these species lose some of their <a href="https://www.earth.com/news/dragonfly-wing-colors-driven-by-climate-and-sexual-selection/" target="_blank" rel="noreferrer noopener">coloration</a> due to climate pressures, they will retain their ability to withstand hotter temperatures because they have already evolved this trait.



This study is one of the first to test whether thermal tolerance co-evolves with reproductive traits.&nbsp;



“Our finding is particularly exciting because dark sexual coloration has evolved over and over across the tree of life and causes a wide variety of other animals to absorb extra heat too - from reptiles to lions and fruit flies,” Leith said.&nbsp;



<h2 class="wp-block-heading" id="h-surviving-in-a-warming-world-nbsp">Surviving in a warming world&nbsp;</h2>



This discovery highlights how evolutionary adaptations in response to reproductive needs may also help species survive in a warming world.



In the context of rapid global warming, being able to predict which species are vulnerable to extinction is crucial for preserving biodiversity. The researchers emphasize the importance of examining not just survival traits, but reproductive traits as well, to get a more comprehensive understanding of how animals respond to environmental <a href="https://www.earth.com/news/how-earths-temperature-has-changed-over-500-million-years/" target="_blank" rel="noreferrer noopener">changes</a>.&nbsp;



“Looking at vulnerability in only one aspect of animals' lives is insufficient. We need a more nuanced understanding of how animals respond to changing environments as whole, complex organisms, in which their reproductive traits might influence their chances of surviving a heat wave, and vice versa,” Leith said.



Although the study analyzed 19 species, the researchers point out that there are thousands of dragonfly species worldwide. Future research could explore whether similar patterns exist across other species and types of animals.&nbsp;



“It would be fantastic to someday test if heat tolerance co-evolves with sexual traits across life on Earth,” Leith concluded.

Wing coloration helps dragonflies withstand heat

Temperature is a key factor in determining where species can...

Rapid warming has so profoundly impacted northern ecosystems that scientists are increasingly concerned about the region's ability to recover from climate shocks, according to a new study focused on Arctic plant resilience.&nbsp;



The researchers found that frequent disturbances like <a href="https://www.earth.com/news/fear-and-anxiety-the-mental-health-impacts-of-wildfires/" target="_blank" rel="noreferrer noopener">wildfires</a>, drought, and deforestation have diminished the resilience of many plant communities in the southern boreal forests. 



<h2 class="wp-block-heading" id="h-plant-resilience-and-carbon-storage">Plant resilience and carbon storage</h2>



This decline in resilience - meaning the plants’ ability to bounce back after environmental stressors - could have serious implications for the Arctic’s role in absorbing carbon dioxide, potentially transforming the region from a carbon sink into a carbon source in the near future.



This shift is particularly troubling because the Arctic and boreal regions have <a href="https://www.earth.com/news/world-environment-day-humans-are-warming-the-planet-faster-than-ever-before/" target="_blank" rel="noreferrer noopener">warmed</a> several times faster than other parts of the world, and continued warming is expected. 



Yue Zhang is the study’s lead author and a graduate student in earth sciences at the <a href="https://www.osu.edu/" target="_blank" rel="noreferrer noopener">Ohio State University</a>. 



“When we talk about the response of forests to climate change, most of the time we’re thinking about the tropical rainforest,” explained Zhang.&nbsp;



“But remote boreal forests are really important in terms of their vast extent, large carbon storage and potential to mitigate climate change.”

Based on historical data from NASA’s <a href="https://above.nasa.gov/" target="_blank" rel="noreferrer noopener">Arctic-Boreal Vulnerability Experiment (ABoVE)</a> program, the researchers utilized remote sensing technology to track subtle changes in vegetation greenness in Alaska and western Canada between 2000 and 2019. 



The goal was to estimate how quickly vegetation recovered from both small-scale fluctuations and large losses, even in areas where significant damage had not yet occurred.



The results showed that while plant resilience in southern boreal forests had decreased over time, resilience appeared to increase in most of the Arctic tundra, despite areas of greening.&nbsp;



Fires, drought, and heat likely contributed to the declining resilience in the southern regions, while shifts in nutrient availability may have helped vegetation thrive in other parts of the Arctic.&nbsp;



<h2 class="wp-block-heading" id="h-uncertainty-of-plant-carbon-storage">Uncertainty of plant carbon storage</h2>



However, even though the release of nutrients could benefit plant growth, rising temperatures threaten to accelerate permafrost melting.&nbsp;



The permafrost stores vast amounts of carbon, and its thawing could release carbon emissions equivalent to those produced by 35 million cars annually, hastening the arrival of climate tipping points.



Zhang emphasized the uncertainty about how much of this carbon will be absorbed by plants versus how much will contribute to further <a href="https://www.earth.com/news/arctic-warming-permafrost-melt-devastating-role-accelerating-global-climate-change/" target="_blank" rel="noreferrer noopener">warming</a>. 



“That’s pretty concerning, because while greening may indicate that productivity and carbon uptake in these regions is increasing now, resilience decline indicates that it may not be sustainable in the longer term.”



<h2 class="wp-block-heading" id="h-an-entire-ecosystem-at-risk">An entire ecosystem at risk</h2>



The study’s findings indicate that the entire ecosystem is at risk, as large portions of the southern <a href="https://www.earth.com/news/single-degree-temperature-warming-boreal-forests-wreak-havoc/" target="_blank" rel="noreferrer noopener">boreal forests</a> are losing stability. This could lead to widespread forest loss and biome shifts in the future. 



Greening regions that simultaneously experience a decline in resilience may be showing signs of distress, suggesting that the ecosystem is struggling to survive before it experiences significant forest loss.&nbsp;



“This is a hot spot of vegetation change where studying it can tell us about the ecosystem stability and what it’s capable of tolerating before it transitions into an alternative state through pervasive forest loss,” warned study senior author Professor Yanlan Liu.



<h2 class="wp-block-heading" id="h-predicting-plant-resilience-nbsp">Predicting plant resilience&nbsp;</h2>



The experts also found that regions at higher elevations with warm, dry conditions and dense vegetation cover were among the most vulnerable to declining resilience.&nbsp;



Yet, there is still a lack of consensus in current climate models regarding how vegetation change and carbon dynamics interact. The team’s work will help to refine these models by providing information about where vegetation shifts are most likely to occur.



Ultimately, Zhang noted that the research has uncovered more subtle changes in the health of the region’s vegetation than previously reported <a href="https://www.earth.com/news/antarctica-is-greening-at-an-unprecedented-rate/" target="_blank" rel="noreferrer noopener">greening</a> and browning trends. Their methodology also offers a new tool for identifying potential vegetation loss in other regions over the coming decades. 



<h2 class="wp-block-heading" id="h-future-research-directions-nbsp">Future research directions&nbsp;</h2>



The team plans to continue improving their predictions of ecosystem changes and advocate for more fieldwork to verify their remote sensing data.



“Scientists need to learn to quantify climate-induced risks through diverse lenses,” Liu said. “On top of satellite remote sensing, we need more ground observations to help us identify ways to leverage these findings to inform future resources and risk management strategies.”



As the Arctic and boreal regions warm at alarming rates, this study sheds light on the fragility of these ecosystems and the need for urgent strategies to preserve their resilience amid rapid climate change.

Arctic ecosystem stability threatened by declining plant resilience 

Rapid warming has so profoundly impacted northern ecosystems that scientists...

Mercury, a potent neurotoxin, is a sneaky culprit contributing to environmental issues. Emitting from common human activities like coal-fired power plants and small-scale gold mining, mercury invariably finds its way into our atmosphere. 



Global mercury emission inventories have been indicating an escalating trend over the years. Yet, recent findings suggest otherwise.



The study was led by an international team of researchers who contributed robust statistical methods and valuable <a href="https://www.earth.com/news/human-driven-mercury-emissions-have-skyrocketed/" target="_blank" rel="noreferrer noopener">atmospheric mercury measurement</a> data.



<h2 class="wp-block-heading" id="h-mercury-emissions-are-dropping">Mercury emissions are dropping</h2>



The study shows that we are not seeing an upward spiral of mercury in our atmosphere. On the contrary, it's been on the decline over the past two decades.



Scientists at <a href="https://www.mit.edu" target="_blank" rel="noreferrer noopener">MIT</a> analyzed data from every available monitoring station in the Northern Hemisphere. Their findings? A clear dip in <a href="https://www.earth.com/news/global-deforestation-directly-linked-to-atmospheric-mercury-emissions/" target="_blank" rel="noreferrer noopener">atmospheric mercury concentrations</a> - approximately 10 percent between the years 2005 and 2020.



Ari Feinberg is a former postdoc in the Institute for Data, Systems, and Society (IDSS) and lead author of the study.



“Our work shows that it is very important to learn from actual, on-the-ground data to try and improve our models and these emissions estimates," said Feinberg.



"This is very relevant for policy because, if we are not able to accurately estimate past mercury emissions, how are we going to predict how mercury pollution will evolve in the future?” 



<h2 class="wp-block-heading" id="h-trend-in-mercury-emissions">Trend in mercury emissions</h2>



The research team adopted two modeling methods to identify the cause of this downward trend. Boiling it down to raw basics, both techniques traced back to a decline in anthropogenic (human-caused) emissions as the driving force.



The puzzle, however, didn't stop there. Global inventories, built using models, reflected opposite trends. 



The mismatch between the models and actual recorded measurements remained shrouded in mystery due to data limitations and gaps in scientific understanding of mercury pollution.



The broader message? "We need to keep measuring and advancing the science," said Noelle Selin, co-author of the study.



<h2 class="wp-block-heading" id="h-making-sense-of-the-mercury-mismatch">Making sense of the mercury mismatch</h2>



A global treaty known as the Minamata Convention was signed in 2013 to cut down on human-caused mercury emissions. Yet, despite international efforts, mercury emission inventories were still shown to increase.



Unraveling the mysteries of mercury emissions posed unique challenges for the researchers. Mercury is the only metal in a liquid state at room temperature and has some exclusive properties.



The limited understanding of all <a href="https://www.earth.com/news/climate-records-shatter-2024-set-to-be-hottest-year-ever/" target="_blank" rel="noreferrer noopener">chemical reactions</a> mercury can undergo, coupled with the smaller network of monitoring stations compared to gases like methane and nitrous oxide, added to the hurdles.



So, the MIT team went above and beyond, developing statistical methods to bridge data gaps. 



"One of the challenges of our study was to come up with statistical methods that can address those data gaps, because available measurements come from different time periods and different measurement networks," said Feinberg.



<h2 class="wp-block-heading" id="h-hypotheses-and-future-directions">Hypotheses and future directions</h2>



While the team's analysis did not pinpoint why emission inventories didn't align with actual data, they proposed some theories.



One possibility involves gaps in information provided by certain countries to global inventories. Another potential cause could be underestimated emissions from small-scale gold mining and mercury-containing products. 



So, what's next? A global effort focused on studying and improving the models used to estimate and evaluate emissions is needed. 



<h2 class="wp-block-heading" id="h-role-of-policy-and-regulation">Role of policy and regulation</h2>



One cannot overlook the crucial role that policy and regulation have played in influencing mercury emissions. 



Initiatives like the Minamata Convention, despite existing discrepancies, highlight international commitment to addressing mercury pollution. This legally binding agreement encourages signatory countries to implement measures that curtail the usage and release of mercury.



Such policies not only intend to lower emissions but also seek to mitigate mercury’s ecological and health impacts. The Convention's strategies include phasing out certain mercury-containing products, promoting sustainable mining practices, and enhancing awareness about the element's risks. 



Effective enforcement and compliance with these regulations are essential to maintaining and potentially improving the current declining trend in mercury emissions. 



<h2 class="wp-block-heading" id="h-collaborative-scientific-endeavors">Collaborative scientific endeavors</h2>



As we explore deeper into the complexities of mercury emissions and their effects, a unified global scientific community is imperative.



By pooling resources and knowledge, scientists can develop more comprehensive models to better understand mercury's atmospheric behavior and its broader environmental implications.



This cooperative approach involves enhancing data sharing, harmonizing monitoring protocols, and fostering innovative research partnerships. 



To address the gaps identified by the researchers, it is essential that future studies not only expand the network of monitoring stations but also incorporate novel technologies that increase the accuracy and consistency of mercury measurements.



While there's much to investigate, one thing is clear: understanding the real-world implications of human activities on our environment is key.



The study is published in the journal <a href="https://www.pnas.org/doi/10.1073/pnas.2401950121" target="_blank" rel="noreferrer noopener">Proceedings of the National Academy of Sciences</a>.

Mercury emissions from human activities are declining

Mercury, a potent neurotoxin, is a sneaky culprit contributing to...

Have you ever wondered about the secret behind the lively leaps of Mexican jumping beans? 



Sold as popular souvenirs along bustling boardwalks, these seemingly animate objects are actually seeds that host the larvae of a small moth species. 



The beans "jump" when the larvae stir within, knocking against the seed wall. But could there be more to this intriguing phenomenon beyond just random movement?



Recently, an in-depth study by researchers at <a href="https://www.binghamton.edu/" target="_blank" rel="noreferrer noopener">Binghamton University</a> has revealed some surprisingly complex behavior within this fascinating microcosm.



<h2 class="wp-block-heading" id="h-jumping-beans-react-to-the-light">Jumping beans react to the light</h2>



Lindsey Swierk, an assistant research professor of biological sciences, was intrigued to find out how these <a href="https://www.earth.com/news/unusual-jumping-behavior-recorded-in-beetle-larvae/" target="_blank" rel="noreferrer noopener">larvae</a> respond to their surroundings. 



The landscapes where the <a href="https://www.earth.com/news/ancient-seeds-reveal-plant-migration-path-from-asia-to-australia/" target="_blank" rel="noreferrer noopener">seeds</a> fall can vary dramatically, from sun-drenched plains to shadowy groves. This prompted Swierk and her students to investigate how the larvae inside the jumping beans react to varying light conditions.



The researchers found that these larvae are capable of registering different light colors, asserting more vigorous jumping actions under specific hues.



<h2 class="wp-block-heading" id="h-jumping-to-escape-the-heat">Jumping to escape the heat </h2>



"When a seed drops to the ground from shrubs, the moth larva inside is at the mercy of whatever environmental temperature the seed experiences,” said Swierk.



“The ground could be scorching hot in direct sunlight. A little <a href="https://www.earth.com/news/city-moths-develop-smaller-wings-survive-light-pollution/" target="_blank" rel="noreferrer noopener">moth</a> larva inside of a seed like this can only withstand so much heat - and so they jump away.”



Interestingly, the bean acts as an "extended architecture" for the larvae - a naturally occurring structure that the organism utilizes without constructing itself.



Much like a hermit crab finds refuge in a borrowed shell, the Mexican jumping bean becomes the adopted home for the larva, offering both shelter and a means of responding to the environment.



<h2 class="wp-block-heading" id="h-how-light-influences-survival">How light influences survival</h2>



To explore this intriguing relationship further, Swierk and her team designed experiments to understand how different light colors influence the behavior of these seed-bound <a href="https://www.earth.com/news/caterpillars-use-their-hair-to-detect-predators-static-electricity/" target="_blank" rel="noreferrer noopener">caterpillars</a>. 



Contrary to expectations, the researchers discovered that light penetrates the seed wall only minimally - less than one percent -suggesting that the larvae rely on incredibly faint cues to sense their surroundings.



Despite this, the larvae respond differently to different light spectra, moving the most under red light and the least under purple light.



"Somehow larvae are picking up on these differences. Whether that's because of very minute temperature changes or because of extremely sensitive photoreceptors, we're not sure yet," noted Swierk. 



“But they're using light somehow as a cue to change their behavior, which probably has to do with the fact that these different lighting spectra are correlated with different environmental conditions."



<h2 class="wp-block-heading" id="h-jumping-beans-under-environmental-stress">Jumping beans under environmental stress</h2>



Continuing their line of investigation into the impact of environmental factors on these larvae, Swierk and her students uncovered an intriguing dilemma. 



The researchers found that larvae possess the ability to repair their host seeds using silk threads, but this might compromise their heat evasion abilities.



The experiments revealed that when seed walls were damaged, the larvae's ability to respond to high heat by jumping decreased. This suggests that the disruption caused by the damage could disconnect the internal silk threads that enable the larva's movement.



Swierk noted that these animals are extremely sensitive to temperature. "A common story here is that we see these larvae using very nuanced cues to change their behavior in response to heat, and we're also seeing that additional stressors like predation attempts can impair their ability to appropriately <a href="https://www.earth.com/news/extreme-weather-has-increased-seasonal-insect-activity/" target="_blank" rel="noreferrer noopener">respond to temperature</a>.”



<h2 class="wp-block-heading" id="h-climate-change-and-insect-behavior">Climate change and insect behavior </h2>



The research does more than shed light on the remarkable world of Mexican jumping beans. The findings have broader implications for our understanding of insect behavior in the era of climate change.



"Responding to temperature change is a big deal. As the climate changes, we need to learn how animals detect imminent thermal stress and what limits their adaptive responses," said Swierk. 



"What we learn about Mexican jumping bean larvae might help us better understand how other insects with limited movement cope with heat stress in their environments."



The study is published in the journal <a href="https://linkinghub.elsevier.com/retrieve/pii/S0376635724001086" target="_blank" rel="noreferrer noopener">Behavioural Processes</a>.

What makes Mexican jumping beans jump?

Have you ever wondered about the secret behind the lively...

According to an alarming annual climate report, Earth's vital signs depict a rapidly deteriorating condition. As we get closer to the UN summit, the urgent need for immediate climate action has never been greater.



The report was authored by an international coalition led by scientists from <a href="https://oregonstate.edu/" target="_blank" rel="noreferrer noopener">Oregon State University</a> (OSU). It communicates a chilling warning that the Earth is heading into a "critical and unpredictable new phase of the climate crisis" that requires swift, decisive action.



<h2 class="wp-block-heading" id="h-perilous-times-on-planet-earth">Perilous times on planet Earth</h2>



The in-depth report, entitled "The 2024 State of the Climate Report: Perilous Times on Planet Earth," identifies several areas - including energy, <a href="https://www.earth.com/news/pollutants-from-fossil-fuels-are-embedded-in-coral-skeletons/" target="_blank" rel="noreferrer noopener">pollutants</a>, nature, food and economy - where significant policy changes are essential.



"A large portion of the very fabric of life on our planet is imperiled," said William Ripple, a professor in the OSU College of Forestry. "We're already in the midst of abrupt climate upheaval, which jeopardizes life on Earth like nothing humans have ever seen."



<h2 class="wp-block-heading" id="h-vital-climate-signs-hit-record-extremes">Vital climate signs hit record extremes</h2>



The report takes into account 35 planetary vital signs to track annual climate change. Among these vital signs, a staggering 25 have reached record-breaking extremes, highlighting the urgency of the situation.



The three <a href="https://www.earth.com/news/earth-just-experienced-its-hottest-day-ever/" target="_blank" rel="noreferrer noopener">hottest days</a> ever recorded occurred in July 2024, highlighting an unprecedented surge in global temperatures. Additionally, heat-trapping fossil fuel emissions have reached alarming levels.



"On the basis of global year-to-date averages, the concentrations of carbon dioxide and methane are at record highs," wrote the study authors.



"Carbon dioxide levels were recently observed to be surging. Furthermore, the growth rate of methane emissions has been accelerating, which is very troubling."



<h2 class="wp-block-heading" id="h-explosive-demand-for-energy">Explosive demand for energy</h2>



Every single day the human population increases by approximately 200,000, and the number of ruminant livestock, which are known to emit harmful <a href="https://www.earth.com/news/state-of-the-climate-greenhouse-gases-hit-a-record-high-in-2022/" target="_blank" rel="noreferrer noopener">greenhouse gases</a> and require substantial energy to rear, increases by roughly 170,000.



In 2023, <a href="https://www.earth.com/news/un-report-current-fossil-fuel-plans-will-shatter-1-5c-climate-goal/" target="_blank" rel="noreferrer noopener">fossil fuel</a> consumption rose by 1.5%, primarily due to significant leaps in coal and oil use. Although renewable energy use also saw enhancement, it is only a fourteenth of fossil fuel use. 



The escalation in renewable energy is mostly due to increased demand rather than its substitution for fossil fuels.



<h2 class="wp-block-heading" id="h-warning-signs-of-a-climate-disaster">Warning signs of a climate disaster</h2>



The report highlights several other pressing issues, including record-breaking highs in Earth’s average surface temperature, ocean acidity, heat content, and <a href="https://www.earth.com/news/global-sea-levels-spiked-dramatically-in-2023/" target="_blank" rel="noreferrer noopener">global sea level</a>, all of which indicate a rapidly worsening climate crisis.



Alarmingly, the mass of ice in Greenland and Antarctica, along with average glacier thickness, has plunged to historic lows, signaling a profound loss of critical ice reserves.



Furthermore, in 2023, the global loss of tree cover amplified from 22.8 million hectares to 28.3 million.



<h2 class="wp-block-heading" id="h-dangerous-climate-feedback-loops">Dangerous climate feedback loops </h2>



The report identifies 28 amplifying feedback loops - such as permafrost thawing and increased methane emissions - that further accelerate and compound the effects of climate change, creating a cycle that threatens to spiral out of control.



In 2023 alone, an estimated 2,325 heat-related deaths occurred in the United States, marking a shocking 117% increase from 1999. 



With increasing climate disasters like the Asian heatwaves killing thousands and displacing millions, the potential for greater geopolitical instability and societal collapse is looming.



<h2 class="wp-block-heading" id="h-roadmap-to-climate-recovery">Roadmap to climate recovery</h2>



The route to recovery includes implementing global carbon pricing, enhancing energy efficiency, curbing greenhouse emissions, restoring biodiverse ecosystems, encouraging plant-based diets, promoting sustainable economics, and incorporating climate education in global curriculums.



"Humanity's future depends on creativity, moral fiber and perseverance. If future generations are to inherit the world they deserve, decisive action is needed, and fast," noted co-author Christopher Wolf. 



The upcoming UN Framework Convention on Climate Change is slated for November 11-22 in Baku, Azerbaijan. It is considered a pivotal opportunity for global progress on climate issues.



<h2 class="wp-block-heading" id="h-alerting-humanity-to-climate-disaster">Alerting humanity to climate disaster</h2>



The climate report represents invaluable contributions from scientists across the globe, with funding from the CO2 Foundation and Roger Worthington.



"Our aim in the present article is to communicate directly to researchers, policymakers, and the public," wrote the experts. 



"As scientists and academics, we feel it is our moral duty and that of our institutions to alert humanity to the growing threats that we face as clearly as possible and to show leadership in addressing them."

<h2 class="wp-block-heading" id="h-invisible-threat-in-urban-air">Invisible threat in urban air</h2>



City dwellers face an unseen danger with every breath. New findings from Emory University researchers suggest that fine particulate matter from <a href="http://earth.com/news/traffic-related-air-pollution-might-increase-alzheimers-risk/" target="_blank" rel="noreferrer noopener">vehicle emissions may significantly elevate the risk of developing Alzheimer's disease</a>. The study examined brain tissue samples from 224 individuals who had confirmed diagnoses and volunteered their brains for scientific research.



<h2 class="wp-block-heading" id="h-disturbing-connections-emerge">Disturbing connections emerge</h2>



Scientists analyzed neuritic plaques — protein clusters that characterize Alzheimer's — while mapping each participant's exposure to PM2.5 particles based on residential location and surrounding traffic density. The correlation proved more alarming than anticipated. Individuals experiencing higher pollution exposure showed nearly double the likelihood of elevated plaque accumulation in brain tissue.



<h2 class="wp-block-heading" id="h-timing-matters">Timing matters</h2>



The research team discovered that pollution exposure during the final year before death demonstrated the strongest association with brain changes. This timeline suggests relatively rapid impacts from environmental toxins on neural health. The connection remained robust even after accounting for various demographic and health factors.



<h2 class="wp-block-heading" id="h-genetic-vulnerability-patterns">Genetic vulnerability patterns</h2>



Perhaps most concerning, people lacking the APOE gene—which naturally predisposes individuals to Alzheimer's — exhibited more than twice the susceptibility to pollution-related brain damage. Study author Dr. Anke Huels noted this indicates environmental elements like air contamination could trigger the disease in cases where hereditary factors don't explain.



<h2 class="wp-block-heading" id="h-public-health-implications">Public health implications</h2>



These findings, published in <a href="https://www.neurology.org/" target="_blank" rel="noreferrer noopener">Neurology</a>, underscore the critical importance of air quality regulations in urban planning. The research suggests that implementing stricter emission controls and promoting alternative transportation could serve as powerful tools in Alzheimer's prevention.



As cities worldwide grapple with growing traffic congestion and aging populations, this study highlights an urgent need for comprehensive approaches to environmental health that protect both our lungs and our minds.

<h2 class="wp-block-heading" id="h-hidden-waters-beneath-ancient-craters">Hidden waters beneath ancient craters</h2>



Scientists have made a startling discovery that challenges everything we thought we knew about <a href="https://www.earth.com/news/saturn-moon-mimas-has-remarkably-young-ocean/" target="_blank" rel="noreferrer noopener">Saturn's moon Mimas</a>. Beneath the heavily cratered surface that earned it the nickname "Death Star" lies a global ocean that formed just 5 to 15 million years ago—a remarkably young age by cosmic standards.



<h2 class="wp-block-heading" id="h-cassini-data-reveals-orbital-secrets">Cassini data reveals orbital secrets</h2>



The discovery, led by Dr. Valéry Lainey of the <a href="https://observatoiredeparis.psl.eu/" target="_blank" rel="noreferrer noopener">Observatoire de Paris</a>, emerged from careful analysis of <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>'s Cassini spacecraft data. By studying subtle irregularities in Mimas's orbit around Saturn, researchers detected the gravitational signature of liquid water hidden 20 to 30 kilometers beneath the moon's icy shell.



<h2 class="wp-block-heading" id="h-an-unlikely-ocean-world">An unlikely ocean world</h2>



At only 400 kilometers in diameter, Mimas seemed like the least likely candidate to harbor a subsurface ocean. Unlike other ocean moons such as Europa and Enceladus, which show clear surface signs of internal activity, Mimas displays no obvious hints of the liquid water beneath its ancient, crater-scarred exterior.



"Mimas is a small moon, and its heavily cratered surface gave no hint of the hidden ocean beneath," explained Dr. Nick Cooper from <a href="https://www.qmul.ac.uk/" target="_blank" rel="noreferrer noopener">Queen Mary University of London</a>, a study co-author.



<h2 class="wp-block-heading" id="h-implications-for-astrobiology">Implications for astrobiology</h2>



The ocean's recent formation makes Mimas a prime target for studying how oceans develop and potentially support life. This discovery adds another member to the exclusive club of ocean worlds in our solar system, each offering unique insights into the conditions necessary for habitability.



The research, published in <a href="https://www.nature.com/" target="_blank" rel="noreferrer noopener">Nature</a> journal, demonstrates how advanced orbital analysis can reveal hidden features of celestial bodies, opening new possibilities for understanding ocean formation throughout the cosmos.

Imagine Earth as a giant snowball, frozen solid from the North Pole to the equator. This wasn't the plot of a science fiction movie – it was our planet's reality 700 million years ago during an extreme ice age that has puzzled scientists for decades.



<h2 class="wp-block-heading" id="h-the-discovery">The discovery</h2>



Australian researchers from the <a href="https://www.sydney.edu.au/" target="_blank" rel="noreferrer noopener">University of Sydney</a> have finally cracked one of geology's greatest mysteries: what caused the Sturtian glaciation and why it persisted for an unprecedented 57 million years. This period occurred long before dinosaurs roamed the Earth, when no complex plants or multicellular animals existed.



Dr. Adriana Dutkiewicz, the study's lead author, describes a world completely unlike today's climate. "Imagine the Earth almost completely frozen over," she explained. "The planet was blanketed in ice from poles to equator, and temperatures plunged."



<h2 class="wp-block-heading" id="h-the-combination-of-climate-factors">The combination of climate factors</h2>



The research team discovered that this massive freeze resulted from a "double whammy" of geological events. First, plate tectonic activity reduced volcanic carbon dioxide emissions to historically low levels. Volcanic activity typically releases CO2 into the atmosphere, creating a greenhouse effect that keeps Earth warm.



Simultaneously, weathering of volcanic rocks in what is now Canada actively absorbed atmospheric CO2, further reducing greenhouse gas concentrations. When atmospheric carbon dioxide levels dropped below 200 parts per million – less than half of today's levels – glaciation engulfed the entire planet.



<h2 class="wp-block-heading" id="h-modern-climate-implications">Modern climate implications</h2>



Published in the journal <a href="https://pubs.geoscienceworld.org/geology" target="_blank" rel="noreferrer noopener">Geology</a>, this research provides crucial insights into Earth's climate system. While geological climate changes occur over millions of years, the study emphasizes that human-induced climate change is happening at a pace ten times faster than previously observed natural changes, highlighting the urgent need to understand our planet's delicate climate balance.

<h2 class="wp-block-heading" id="h-a-contrasting-climate-response">A contrasting climate response</h2>



Most coastal towns are <a href="https://www.earth.com/news/sinking-land-will-intensify-the-effects-of-rising-sea-levels/" target="_blank" rel="noreferrer noopener">preparing for higher sea levels</a>, but <a href="https://www.earth.com/news/greenland-no-longer-has-to-worry-about-rising-sea-levels/" target="_blank" rel="noreferrer noopener">Greenland presents</a> a different scenario during climate change. The ground there is rising at a remarkable rate. Over the past decade, some areas have lifted about 20 centimeters, which translates to roughly 2 meters per century. This rate significantly exceeds current projections for sea level rise.



<h2 class="wp-block-heading" id="h-geological-rebound-process-through-climate-change">Geological rebound process through climate change</h2>



The mechanism behind this phenomenon is straightforward. As the ice sheet melts, the immense weight is removed from the bedrock, causing the land to rebound upward. This process resembles the way compressed material springs back when pressure is released.



<h2 class="wp-block-heading" id="h-scientific-monitoring-networks">Scientific monitoring networks</h2>



Researchers at the <a href="https://www.dtu.dk/english/" target="_blank" rel="noreferrer noopener">Technical University of Denmark</a> are documenting this uplift using the GNET network, consisting of 61 GPS stations positioned around Greenland's coast. These sensors can detect movement with millimeter precision, providing detailed measurements of the ongoing changes.



The data reveal that current uplift rates exceed the gradual rebound occurring since the last ice age ended approximately 12,000 years ago. This acceleration corresponds directly with increased ice sheet melting rates.



<h2 class="wp-block-heading" id="h-coastal-transformation">Coastal Transformation</h2>



This uplift is actively reshaping Greenland's coastline. New islands and rocky formations, called "skerries," are emerging as previously submerged land surfaces rise above the water level. This represents a notable contrast to global concerns about rising seas.



The study, published in Geophysical Research Letters, demonstrates the varied regional impacts of climate change. While many locations face rising water levels, Greenland's bedrock is literally rising above the surrounding seas.



The full study was recently published in <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2023GL104851" target="_blank" rel="noreferrer noopener">Geophysical Research Letters</a>.

<h2 class="wp-block-heading" id="h-ai-agent-training-transforms-the-workplace-fear-factor-into-a-competitive-advantage">AI agent training transforms the workplace 'fear factor' into a competitive advantage</h2>



Organizations that offer comprehensive artificial intelligence training to their workers find remarkable value that extends well beyond basic <a href="https://www.earth.com/news/mind-wandering-might-be-more-productive-than-you-think/" target="_blank" rel="noreferrer noopener">productivity improvements</a>. Emerging research demonstrates that carefully crafted AI training programs <a href="https://www.earth.com/news/ai-does-not-replace-human-creativity-but-enhances-it/" target="_blank" rel="noreferrer noopener">enhance</a> corporate performance, lower operational costs, and dramatically improve employee psychological well-being by turning workplace uncertainty into professional empowerment.



<h2 class="wp-block-heading" id="h-addressing-the-widespread-ai-anxiety-crisis-among-us">Addressing the widespread 'AI anxiety' crisis among us</h2>



A staggering 53% of employees expressed concern that the use of AI tools to automate work tasks could make them appear disposable to their employers, according to <a href="https://www.microsoft.com/" target="_blank" rel="noreferrer noopener">Microsoft</a>'s 2024 workplace survey. Such pervasive worry about being substituted by machines has caused what researchers have termed "AI technostress" – a psychological state that can result in occupational burnout and poorer mental well-being.



Data published in <a href="https://www.nature.com/palcomms/" target="_blank" rel="noreferrer noopener">Humanities and Social Sciences Communications</a> showed that belief in AI learning ability was a moderator in the link between technology adoption and work pressure, and higher confidence significantly lowered negative psychological responses. Workers provided ample training to become competent with AI software have significantly lower stress.



Companies like <a href="https://www.mindstudio.ai/" target="_blank" rel="noreferrer noopener">MindStudio</a> have platforms for building what are known as "AI Agents". In essence, AI Agents are simply tools that employees can build for themselves or their teams quickly and inexpensively. MindStudio will even train entire companies, from the CEO on down, at no cost. By letting MindStudio empower employees, companies avoid hiring more IT staff, buying more software, and implementing solutions to problems that do not exist.



MindStudio even has partners locally for companies, like <a href="http://www.dominnus.com" target="_blank" rel="noreferrer noopener">Dominnus</a> with offices in the Carolinas, California, and Denver, to help build AI Agents and support employees as they become resident AI experts for their organization. The training provided by MindStudio is applicable across other AI Agent building platforms as well.



<h2 class="wp-block-heading" id="h-revolutionary-productivity-through-focused-learning">Revolutionary productivity through focused learning</h2>



Organizations that implement large-scale AI training programs achieve dramatic outcomes. Employees performed tasks significantly better when they utilized AI support compared to when they didn't, according to <a href="https://www.nngroup.com/" target="_blank" rel="noreferrer noopener">Nielsen Norman Group</a> research findings. Their study documented productivity increases of 66% for a variety of professional tasks.



Federal Reserve Bank of St. Louis research finds workers record 33% higher productivity in time working with generative AI tools. The benefit is equivalent to 5.4% of work time savings for AI users – around 2.2 hours per week for full-time workers.



<h2 class="wp-block-heading" id="h-psychological-well-being-benefits-through-ai-competence">Psychological well-being benefits through AI competence</h2>



The emotional transformation when employees are provided with proper technology training is a fundamental transformation from fear to professional confidence. A survey of 600 employees across industries, carried out by ScienceDirect, proved that AI capabilities strengthen work environment commitment and improve job satisfaction.



A <a href="https://www.lut.fi/en" target="_blank" rel="noreferrer noopener">LUT University</a> study discovered that AI adoption has no direct effect on workers' well-being but does so indirectly through working conditions like task optimization and safety protocols. Strategically deployed AI that involves correct training can actually increase workplace mental well-being.



<h2 class="wp-block-heading" id="h-from-replacement-anxiety-to-partnership-confidence">From 'replacement anxiety' to 'partnership confidence'</h2>



Although 35% of those interviewed in recent McKinsey studies were concerned about workforce displacement, firms with large-scale training initiatives witness such fears dissipate quickly. The World Economic Forum found that two out of three respondents believe AI competencies will enhance their career prospects and job marketability.



This shift from fear to trust has measurable implications for job satisfaction. Applied Sciences research indicates AI can create tailored wellness programs based on individual employee requirements.



<h2 class="wp-block-heading" id="h-financial-benefits-of-increased-retention">Financial benefits of increased retention</h2>



The mental health advantages of AI learning have a direct impact on organizational bottom lines in the form of a positive feedback cycle with high retention of employees. Recent ROI research validates that artificial intelligence learning has a beneficial impact on employee turnover and satisfaction levels.



PriceWaterhouseCoopers' research documents 20% to 30% improvements in productivity, market speed, and revenue in organizations that attempt systematic AI adoption through comprehensive training.



<h2 class="wp-block-heading" id="h-environmental-advantages-of-ai-enabled-teams">Environmental advantages of AI-enabled teams</h2>



AI training has unforeseen environmental benefits as it makes the work environment more efficient. According to a study in Scientific Reports, the carbon footprint in writing and illustrating work is significantly lower when AI performs it compared to humans. AI software produces 130 to 1,500 times less CO2 equivalent per page of text created than human authors.



In addition, AI-driven remote work functionality significantly reduces environmental impact. Research by Cornell University and Microsoft indicates that remote workers reduce greenhouse gas emissions by up to 54% by not commuting daily to offices. Hybrid workers working remotely two to four days a week can reduce their carbon footprint by 11% to 29%.



<h2 class="wp-block-heading" id="h-cumulative-organizational-advantages">Cumulative organizational advantages</h2>



The compounding gains of better mental well-being, reduced turnover, increased productivity, and environmental benefits flow to enterprises from the pairing. McKinsey analysis estimates the long-term AI potential at $4.4 trillion in incremental productivity growth opportunity from business use cases.



As of now, 75% of knowledge workers globally utilize generative AI, mirroring widespread adoption patterns. Organizations that provide organized training and assistance see the most favorable results in productivity, worker satisfaction, and ecological sustainability.



The research overwhelmingly indicates that companies that invest in proper AI education, like that offered through <a href="https://www.mindstudio.ai" target="_blank" rel="noreferrer noopener">MindStudio</a>, establish win-win scenarios where employees are both more empowered and less stressed, and companies enjoy the gains of increased productivity, reduced turnover, and improved mental health outcomes throughout their workforce.

<h2 class="wp-block-heading" id="h-a-natural-solution-to-disease-through-crop-modification">A natural solution to disease through crop modification.</h2>



The agricultural industry stands at a crossroads between productivity and environmental responsibility, and crop modification often carries a negative connotation. While chemical pesticides have long been the go-to solution for crop protection, their harmful effects on ecosystems and human health have prompted scientists to seek alternatives. The recent breakthrough by <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> researchers offers a promising path forward through the precise manipulation of plant-associated microbial communities.



<h2 class="wp-block-heading" id="h-the-science-behind-microbial-partnerships">The science behind microbial partnerships</h2>



Plants naturally harbor diverse ecosystems of bacteria, fungi, and other microorganisms that function as biological allies. These microscopic partners contribute to disease resistance, nutrient absorption, and stress tolerance. However, until now, scientists lacked the tools to deliberately reshape these communities to enhance crop protection.



The Southampton team's approach centered on <a href="https://www.earth.com/news/engineered-plant-microbiomes-the-future-of-crop-protection/" target="_blank" rel="noreferrer noopener">modifying lignin biosynthesis genes in rice plants</a>. This strategic intervention altered the plant's metabolic output, creating conditions that favored beneficial bacterial populations while suppressing harmful ones. The result was a living defense system embedded within the plant itself.



<h2 class="wp-block-heading" id="h-implications-for-global-food-security">Implications for global food security</h2>



The successful demonstration against Xanthomonas oryzae, the pathogen responsible for bacterial blight in rice, represents more than a laboratory achievement. Rice feeds nearly half the world's population, and bacterial blight causes devastating crop losses annually. Traditional control methods rely heavily on pesticides that contaminate soil and water systems.



<h2 class="wp-block-heading" id="h-looking-beyond-disease-resistance">Looking Beyond Disease Resistance</h2>



While disease protection represents the immediate application, the research framework opens doors to broader agricultural improvements. Future developments could engineer microbiomes to enhance nutrient uptake, reducing dependence on synthetic fertilizers. This dual benefit addresses both crop productivity and environmental sustainability.



<h2 class="wp-block-heading" id="h-the-path-forward">The path forward</h2>



As this technology advances from laboratory to field applications, it promises to reshape sustainable agriculture. The ability to program plants with their own biological defense systems could herald a new era where crops protect themselves naturally, reducing chemical inputs while maintaining yields necessary for global food security.

<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?



The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.



<h2 class="wp-block-heading">What was acid rain?</h2>



Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.



<h2 class="wp-block-heading">The science behind it</h2>



Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.



While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.



<h2 class="wp-block-heading">The crisis at its peak</h2>



During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.



<h2 class="wp-block-heading">Environmental devastation</h2>



The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.



By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.



Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.



<h2 class="wp-block-heading">Economic impact</h2>



Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.



<h2 class="wp-block-heading">The solution: government action and technology</h2>



Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.



<h2 class="wp-block-heading">The Clean Air Act of 1990</h2>



The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.



<h2 class="wp-block-heading">Cap-and-trade success</h2>



Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.



The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.



<h2 class="wp-block-heading">Technology advances</h2>



Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.



The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today">Why we don't hear about it today</h2>



Why did acid rain disappear from headlines? Simple: the problem was largely solved.



<h2 class="wp-block-heading">Success doesn't make news</h2>



There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.



<h2 class="wp-block-heading">Mission accomplished</h2>



The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.



<h2 class="wp-block-heading" id="h-is-it-really-gone">Is it really gone?</h2>



The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.



EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.



<h2 class="wp-block-heading">What this teaches us</h2>



The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.



Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.



<h2 class="wp-block-heading">Conclusion</h2>



Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.



Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.



This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.



Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.

<h2 class="wp-block-heading">Frequently Asked Questions</h2>



1. Is acid rain completely gone? No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.



2. How long did solving take? Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.



3. What made the solution successful? Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.



4. Do other countries have acid rain problems? Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.



5. Could acid rain return? Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.



6. Can you recommend any teaching tools on the subject of "acid rain"? The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a>

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</a>.

Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes how Earth is unique in our solar system for its ability to sustain liquid water on its surface. But now, the water cycle is shifting as the climate warms, and scientists must find ways to predict how these changes will affect water availability.



Overall, 96 percent of Earth's water is saltwater, and nearly all of freshwater is found in ice and groundwater. These sources of water are linked as it passes through solid, liquid and gas phases.



In a warmer climate, the water cycle will be transformed. It will be easier for water to evaporate and form clouds, and storms will become more frequent and intense. Some regions will get too much water, while others will be left without enough water. In addition, soil moisture will be lost - which threatens food security.



Scientists are using satellite data from over the last 40 years to track changes that are happening in the water cycle. This will ultimately help us prepare for extreme events and better manage our water resources, according to ESA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard Space Flight Center</a> features images of Saturn from NASA’s Hubble Space Telescope. The photographs capture the start of the mysterious "spoke season" on Saturn - when unexplained features appear on its rings. 



According to NASA, both the cause of the spokes and their seasonal variability have yet to be fully explained by planetary scientists.



"Like Earth, Saturn is tilted on its axis and therefore has four seasons, though because of Saturn's much larger orbit, each season lasts approximately seven Earth years. Equinox occurs when the rings are tilted edge-on to the Sun," explains NASA.



"The spokes disappear when it is near summer or winter solstice on Saturn. (When the Sun appears to reach either its highest or lowest latitude in the northern or southern hemisphere of a planet.) As the autumnal equinox of Saturn's northern hemisphere on May 6, 2025, draws near, the spokes are expected to become increasingly prominent and observable."



Experts believe that the spokes may be a product of the planet's variable magnetic field. When magnetic fields interact with solar wind, an electrically charged environment is created. This phenomenon is visible on Earth as the northern lights.&nbsp;



"Scientists think that the smallest, dust-sized icy ring particles can become charged as well, which temporarily levitates those particles above the rest of the larger icy particles and boulders in the rings," says NASA.



The spokes were first observed in the early 1980s by NASA's Voyager mission. Depending on the angle of the rings, the spokes can appear dark or light.



"Thanks to Hubble's OPAL program, which is building an archive of data on the outer solar system planets, we will have longer dedicated time to study Saturn’s spokes this season than ever before," said NASA senior planetary scientist Amy Simon, head of the Hubble Outer Planet Atmospheres Legacy (OPAL) program.



"Despite years of excellent observations by the Cassini mission, the precise beginning and duration of the spoke season is still unpredictable, rather like predicting the first storm during hurricane season."
