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.

Hidden plastic graveyard uncovered in the deep Mediterranean Sea

In the southeastern Mediterranean, the deep seafloor is turning into a massive storage ground for plastic packaging, especially bags.

Land subsidence is the shifting and sinking of the ground, and it can be disastrous for low lying countries. Subsidence can be caused by several factors, including erosion, earthquakes, mining, and even rapid urbanization. 

Because of the risks that subsidence poses to urban areas and agriculture, it is crucial to find ways to monitor and map subsidence in regions where city infrastructure, buildings, homes, and crop yields are under threat.

Many regions in Italy are impacted by subsidence, which makes the country a prime region to test monitoring and mapping techniques. 

Currently, groundwater monitoring and optical leveling are used to map subsidence, but tracking land shifts over the long term requires a more comprehensive approach. 

This is why researchers from the <a href="https://www.unifi.it/changelang-eng.html">University of Florence</a> compiled radar data from the <a href="https://www.esa.int/">European Space Agency’s</a> <a href="https://sentinel.esa.int/web/sentinel/missions/sentinel-1">Copernicus Sentinel-1 mission</a> to create over ground deformation maps for Tuscany showing surface sinking over time. 

Satellite <a href="https://www.earth.com/news/widespread-burn-scars-africa/">radar imaging</a> is one of the most accurate ways to subsidence and damage.

“Satellite data, acquired with short revisiting times and promptly processed, can contribute to the detection of changes in ground deformation patterns, and can feed a decision support system for hydrogeological risk mitigation strategies,” said Professor Nicola Casagli from the University of Florence. 

Having a detailed record of subsistence can help researchers focus on unstable areas not immediately identifiable by ground monitoring techniques.  

“Thanks to Copernicus Sentinel-1, the SAR industry paradigm has definitely changed from ‘mapping’ to ‘monitoring.’ Tuscany is the first region in Italy to benefit from this,” said Alessandro Ferretti, the CEO of <a href="https://site.tre-altamira.com/">TRE ALTAMIRA</a>, which works with satellite data to provide mapping solutions.

Deep in the ocean below Bermuda, geoscientists have found the first direct evidence that material from deep within Earth's mantle can gradually seep up through the surface to form <a href="http://www.earth.com/news/volcanoes-earths-largest-mass-extinction/">volcanoes</a>. This material is located in a part of the mantle known as the transition zone, which is a layer rich in water, crystals, and melted rock.

Volcanoes are known to form when tectonic plates collide. However, the finding that material percolating 250 to 400 miles beneath the planet's crust can produce volcanoes is a new discovery. 

Study senior author Esteban Gazel is an associate professor in the Department of Earth and Atmospheric Sciences at <a href="https://www.cornell.edu/">Cornell University</a>. 

“We found a new way to make volcanoes. This is the first time we found a clear indication from the transition zone deep in the Earth's mantle that volcanoes can form this way,” said Professor Gazel. “We were expecting our data to show the volcano was a mantle plume formation - an upwelling from the deeper mantle - just like it is in Hawaii.” 

The researchers used a 2,600-foot core sample that had been drilled in 1972 to examine isotopes, trace elements, and evidence of volatile material. The assessment provided the team with a volcanic history of Bermuda.

The study revealed that a disturbance in the transition zone 30 million years ago caused an upwelling of magma material that formed a now-dormant volcano under the Atlantic Ocean and then formed Bermuda.

“I first suspected that Bermuda's volcanic past was special as I sampled the core and noticed the diverse textures and mineralogy preserved in the different lava flows,” said study co-author Sarah Mazza of the University of Münster. “We quickly confirmed extreme enrichments in trace element compositions. It was exciting going over our first results ... the mysteries of Bermuda started to unfold.”

Even though isotopes of oceanic lavas have been analyzed for more than five decades, the extreme isotopes measured in the Bermuda lava core had not been seen before. It was these unusual isotopic compositions that allowed the scientists to identify the unique source of the lava.

“If we start to look more carefully, I believe we're going to find these geochemical signatures in more places,” said co-author Professor Michael Bizimis.

According to Professor Gazel, the research provides a new connection between the transition zone layer and volcanoes on the surface of Earth. 

“With this work we can demonstrate that the Earth's transition zone is an extreme chemical reservoir. We are now just now beginning to recognize its importance in terms of global geodynamics and even volcanism,” said Professor Gazel.

“Our next step is to examine more locations to determine the difference between geological processes that can result in intraplate volcanoes and determine the role of the mantle's transition zone in the evolution of our planet.”

The study is published in the journal <a href="https://www.nature.com/">Nature</a>.

Climate change will bring more days of sweltering heat to the northeast. A new study from <a href="https://home.dartmouth.edu/">Dartmouth College</a> has revealed that there will be far more record heat across the Northeast in the coming decades. According to the researchers, by the year 2060, the hottest day of the year could be multiplied by 23 at the current rate of <a href="http://www.earth.com/news/co2-levels-highest-ever/">greenhouse gas emissions</a>.

Of the rural Northeast counties represented in the study, those in the lowest income brackets are expected to be hit the hardest. Compared to wealthier counties, these communities will be disproportionately affected by increases in extremely hot days. Climate change will bring more days of sweltering heat to the northeast

“In other words, by the middle of this century, every year counties with the lowest income in the Northeast will experience more than two decades worth of our current hottest day. Our findings agree with other climate change studies that have found increasing heat extremes and higher maximum daily temperatures across this region in the future,” explained study lead author Professor Jonathan Winter.

The research was focused on rural counties in the Northeast from Maine to West Virginia with populations of 250,000 or less. 

“Our projections suggest that climate change adaptation strategies in the rural Northeast should emphasize developing resilience to heat waves, such as increasing access to public spaces with air conditioning and improving health care responses to emergencies initiated or exacerbated by heat,” said Professor Winter.

“This is especially important for counties in the lowest income quartile, who will be especially vulnerable to extreme heat events due in part to their growing populations.”

In addition to the higher frequency of daily heat events in the Northeast, daily extreme precipitation is projected to increase by 15 to 20 percent based on different greenhouse gas emissions scenarios. 

Meanwhile, the incidence of daily extreme cold events will substantially decrease. The average coldest daily temperature recorded from 1976-2005 will only occur once every four or five years by 2046-2075.

The study is published in the journal <a href="https://www.tandfonline.com/toc/raag21/current">Annals of the American Association of Geographers</a>.

In a study that compared 25 years of satellite data from the <a href="https://www.esa.int/">European Space Agency</a> (ESA), scientists have found that 24 percent of the glacier ice in <a href="http://www.earth.com/news/antarctica-increase-ice-mass-loss/">West Antarctica</a> is now unstable as a result of thinning caused by warming ocean water. 

Experts at the <a href="https://cpom.org.uk/">UK Centre for Polar Observation and Modelling</a> (CPOM) used over 800 million measurements of Antarctic ice sheet height from between 1992 and 2017. The data was recorded by radar altimeter instruments on the ERS-1, ERS-2, Envisat, and CryoSat satellite missions.

Along with simulations of snowfall over the same time period, the measurements made it possible to distinguish which changes in ice-sheet height had been caused by weather events that affect snow, and which were caused by longer-term climate changes that affect ice.

Some regions in the ice sheet had thinned by up to 122 meters, and the most rapid changes were discovered in areas where ocean melting has triggered glacier imbalance. “Parts of Antarctica have thinned by extraordinary amounts. So we set out to show how much was down to changes in climate and how much was instead due to weather,” said CPOM Director Andy Shepherd.

The team determined that fluctuations in snowfall drive small changes in ice height over large areas for a few years at a time, and the most extreme changes in ice thickness coincide with signs of glacier imbalance that have persisted for decades.

“Knowing how much snow has fallen has really helped us to isolate the glacier imbalance within the satellite record. We can see clearly now that a wave of thinning has spread rapidly across some of Antarctica’s most vulnerable glaciers, and their losses are driving up sea levels around the planet,” said Professor Shepard.

“After 25 years, the pattern of glacier thinning has spread across 24% of West Antarctica, and its largest ice streams – the Pine Island and Thwaites Glaciers – are now losing ice five times faster than they were in the 1990s. Altogether, ice losses from East and West Antarctica have added 4.6 mm of water to global sea level since 1992.”

“This is a fantastic demonstration of how satellite missions can help us to understand how our planet is changing,” said ESA engineer Marcus Engdahl. “The polar regions are hostile environments and are extremely difficult to access from the ground. Because of this, the view from space is an essential tool for tracking the effects of climate change.”

The study is published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/journal/19448007">Geophysical Research Letters</a>.

Research led by the <a href="https://www.utas.edu.au/">University of Tasmania</a> has revealed that a remote territory of Australia in the Indian Ocean is immersed in plastic debris. The beaches of the Cocos (Keeling) Islands were found to be littered with 414 million pieces of <a href="http://www.earth.com/news/plastic-pollution-health-threats/">plastic pollution</a> totaling around 238 tons. 

The study’s lead author, Dr. Jennifer Lavers, captured worldwide attention in 2017 when she reported that beaches on Henderson Island in the South Pacific had the highest known density of plastic debris anywhere on the planet. 

Although the density of the plastic pieces found on the Cocos (Keeling) Islands beaches is lower than what was found on Henderson Island, the total volume outweighs the South Pacific island’s debris by 221 million tons. 

Dr. Lavers said that remote islands like these, which do not have large human populations depositing garbage nearby, provide an indication of the amount of plastic debris circulating in the world's oceans.

“Islands such as these are like canaries in a coal mine and it's increasingly urgent that we act on the warnings they are giving us,” said Dr. Lavers. “Plastic pollution is now ubiquitous in our oceans, and remote islands are an ideal place to get an objective view of the volume of plastic debris now circling the globe.”

“Our estimate of 414 million pieces weighing 238 tons on Cocos (Keeling) is conservative, as we only sampled down to a depth of 10 centimeters and couldn't access some beaches that are known debris ‘hotspots.’ Unlike Henderson Island, where most identifiable debris was fishing-related, the plastic on Cocos (Keeling) was largely single-use consumer items such as bottle caps and straws, as well as a large number of shoes and thongs.”

Study co-author Dr. Annett Finger pointed out that the global production of plastic continues to increase, and that almost half of the plastic produced over the past 60 years was manufactured in the last 13 years.

“An estimated 12.7 million tonnes of plastic entered our oceans in 2010 alone, with around 40 percent of plastics entering the waste stream in the same year they're produced,” said Dr. Finger. “As a result of the growth in single-use consumer plastics, it's estimated there are now 5.25 trillion pieces of ocean plastic debris.”

“Plastic pollution is a well-documented threat to wildlife and its potential impact on humans is a growing area of medical research. The scale of the problem means cleaning up our oceans is currently not possible, and cleaning beaches once they are polluted with plastic is time consuming, costly, and needs to be regularly repeated as thousands of new pieces of plastic wash up each day.”

“The only viable solution is to reduce plastic production and consumption while improving waste management to stop this material entering our oceans in the first place.”

The study is published in the journal <a href="http://www.nature.com/scientificreports">Scientific Reports</a>.

Years of satellite data help map ocean salinity levels. Years of satellite data have helped researchers create one of the longest and most accurate datasets of global ocean salinity.

Having an accurate record of sea-surface salinity will aid in future studies examining how human-made climate change is impacting the world’s water cycle and ocean currents as both of these are directly linked to water salinity.

The project, which will be presented at the <a href="https://www.earth.com/news/esas-living-planet-symposium/">Living Planet Symposium,</a> is part of the <a href="https://www.esa.int/Our_Activities/Observing_the_Earth/Space_for_our_climate/ESA_s_Climate_Change_Initiative/(print)">European Space Agency’s Climate Change Initiative</a> which seeks to incorporate satellite data into long-term datasets for 22 climate variables, salinity among them. 

Ocean buoys and ships have long been used to measure sea salinity and records as far back as the 1950s show a growing trend in increasing salinity in some parts of the ocean. However, inconsistent and limited datasets have made studying this trend a challenge. Years of satellite data help map ocean salinity levels

To help remedy this, ESA researchers turned to the skies and created a thorough dataset spanning nine years of Earth observation data collected from satellites. 

Data from <a href="https://www.esa.int/Our_Activities/Observing_the_Earth/SMOS">ESA’s SMOS</a> satellite mission, the <a href="https://smap.jpl.nasa.gov/">US’s SMAP mission</a>, and the <a href="https://aquarius.nasa.gov/">Aquarius satellite mission</a> were used to help compile the dataset. 

“By combining and comparing measurements from the missions’ various radiometers, the precision of sea-surface salinity maps is improved by roughly 30% thanks to the increased number of measurements and reduced inter-calibration error,” said Jacqueline Boutin, the leader of the research team. 

Ocean salinity plays a role in both ocean current circulation and seawater density, which is the amount of water that is denser than freshwater. Sea salinity is also linked to the global water cycle, and sea-surface saltiness impacts the amount of freshwater that evaporates from the ocean. 

Now, the dataset can help researchers understand the role of climate change in ocean salinity, how ocean salinity impacts El Nino, and ocean salinity’s impact on weather events like cyclones. 

The researchers plan to use the dataset in several water cycle studies in the Bay of Bengal where severe cycles are common.

Geomagnetic storm could light up the night sky with auroras this week. The <a href="https://www.noaa.gov/">National Oceanic and Atmospheric Administration</a> (NOAA) <a href="https://www.swpc.noaa.gov/">Space Weather Prediction Center</a> (SPPC) has issued a geomagnetic storm watch going into effect on May 15th and lasting through May 17th. 

The G2 moderate storm watch forecasts back to back <a href="https://www.earth.com/image/a-beautiful-aurora-borealis-seen-from-the-space-station/">bright displays of the aurora</a> which could be visible in parts of the northern United States and Canada depending on weather conditions and location.

Three Coronal Mass Ejections (CMEs) were observed by the SWPC earlier this week making their way toward Earth.  When these ejections of bright plasma from the Sun collide with Earth’s magnetic field, it can disrupt power grids and communication systems. 

“The first two CME events are expected to arrive on 15 May, and the third CME is anticipated to arrive the later half of 16 May,” the <a href="https://www.swpc.noaa.gov/news/g1-minor-watch-effect-15-16-may-2019-utc-days">SWPC</a> said. 

What causes the aurora is the sudden spike in electrons in Earth’s upper atmosphere, and although the SWPC forecasts that the storm will peak at G2 levels, there is little fear that the solar flares will cause much of a disturbance to satellites or power lines. 

However, the strength of the storm is good news for people in the Northern Hemisphere who may be lucky enough to catch a glimpse of the Aurora Borealis. 

People living in Canada, Minnesota, Michigan, and Maine have a good chance of seeing the Northern lights light up the night sky if conditions are favorable. 

The SWPC even forecasts aurora displays as far south as Illinois, New York, and Ohio if the geomagnetic storm is strong enough.

The deepest-ever human ocean dive reveals that our garbage beat us there. Former naval officer Victor Vescovo has now descended deeper into the ocean than any other human. His record-setting solo submarine dive seven miles deep in the <a href="http://www.earth.com/news/life-found-mariana-trench/">Mariana Trench</a> has produced three new marine species, along with some less exciting discoveries in the form of garbage. 

According to the <a href="https://www.washingtonpost.com/">Washington Post</a>, Vescovo was literally mapping uncharted new territory in the world’s deepest underwater trench when he noticed plastic trash. 

News outlets initially reported that he saw a candy wrapper and a plastic bag, but a <a href="https://www.reuters.com/">Reuters</a> report referred to the waste spotted by Vescovo as being “metal or plastic objects, one with writing on it.”

“I was disappointed to see human contamination in the deepest point in the ocean,” said Vescovo. “With over 7 billion people on the Earth, the oceans are going to be impacted negatively by mankind, but I hope we can at least minimize it in the future.” The deepest-ever human ocean dive reveals that our garbage beat us there

Vescovo told the <a href="https://www.washingtonpost.com/">Washington Post</a> he spent around four hours on the floor of the Mariana Trench, and he was amazed by his surroundings. ‘There was definitely life at the very bottom of the ocean. It was not dead by any means... I felt very excited, privileged to get to see it, but also very much at peace because it really is a quiet, peaceful, place.”

Scientists identified at least three new species of marine animals during the expedition, including a crustacean that resembles a shrimp. The <a href="https://www.bbc.co.uk/">BBC</a> reports that the specimens collected by the team will be tested for microplastics.

Vescovo’s historic dive replaces a previous record set by movie director James Cameron in 2012 by just over 50 feet.

According to a new study, led by Gabriela Prestes-Carneiro of <a href="http://www.ufopa.edu.br/ufopa/">Federal University of Western Para, Brazil</a>, a network of fish ponds in the seasonal drylands of Bolivia supported a permanent human settlement about 1,000 years ago. 

This research shows how exactly humans modified their environment to support themselves through the months-long Amazon Basin <a href="http://www.earth.com/news/drought-ozone-pollution-levels/">droughts</a>.

Previous studies have found that humans settled the Llanos de Mojos region in central Bolivia — an area that experiences flooding rain from October to April and then drought throughout the rest of the year — around 500 AD. 

These people built earthen mounds on which to settle, and built a series of shallow ponds, all connected by canals, in order to trap rainwater to last them through the dry season.

Prestes-Carneiro and her team conducted osteological and taxonomic identifications on the remains of over 17,000 fish at the most significant archaeological pond-based site in this region, called Loma Salavtierra. 

They were able to identify over 35 different taxa of fish, with the majority being swamp-eels, armored catfish, lungfish, and tiger-fish. All of these species are adapted to live in low-oxygen, level-fluctuating waters — as was the case of the pond waters.

These findings, published in <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0214638">PLOS One</a>, tell researchers that these ponds were most likely used to harvest fish year round.

"The savanna, in contrast to the large Amazonian rivers, presents a distinct set of fishing habitats where humans likely established specific fishing strategies,” the authors note.

Research led by the Christian charity group <a href="https://www.tearfund.org/">Tearfund</a> has revealed that plastic waste is responsible for a death every 30 seconds in the developing world. Sir David Attenborough, the vice-president of <a href="https://www.fauna-flora.org/">Fauna &amp; Flora International</a>, referred to plastic pollution as an “unfolding catastrophe.”

The researchers found that between 400,000 and a million people die each year from diseases such as cancer caused by living in close proximity to mismanaged <a href="http://www.earth.com/news/plastic-pollution-health-threats/">plastic waste</a>. 

The plastic garbage serves as a breeding ground for mosquitoes, flies, and rats, which can carry malaria and dengue fever. Plastic waste also accumulates in waterways and causes flooding that can spread waterborne diseases. 

Children who are exposed to the plastic pollution are twice as likely to get intestinal bugs like cholera, which is extremely dangerous and often deadly. 

Single-use plastics shipped from wealthy countries are a major contributor to the issue. The researchers said that Britain alone exports 650,000 tons of plastic waste every year to countries like Malaysia and Indonesia.

According to the report, “No Time to Waste,” a double-decker busload of plastic waste is burned or dumped in developing countries every second. The burning of plastic waste causes an estimated one-fifth of the 3.7 million deaths that are attributed to air pollution each year. 

“This report is one of the first to highlight the impacts of plastic pollution not just on wildlife but also on the world’s poorest people,” said Sir Attenborough.

“It is high time we turn our attention fully to one of the most pressing problems of today - averting the plastic pollution crisis - not only for the health of our planet, but for the wellbeing of people around the world.”

The authors of the report are calling for international companies to cut the amount of single-use plastic products they produce in half by 2025. In addition, Tearfund is asking four major companies - Nestle, PepsiCo, Coca-Cola, and Unilever - to take responsibility for their plastic waste in developing countries. 

The research was presented by Sir David Attenborough at a meeting of the Wall Street Journal CEO Council.

Plastic waste kills a person every 30 seconds in developing countries

Research led by the Christian charity group Tearfund has revealed...

M-44 devices, often known as “cyanide bombs,” are a controversial tool used by government officials to control predation on livestock and endangered species. These tools are placed into the ground near areas where coyotes, foxes and other predator species roam. When the device is set off by passing wildlife, it sprays sodium cyanide, killing the predator.

Environmentalists and animal advocates have long called for the end of their use. With the recent ban on the use of M-44s for predator control in Oregon, groups are one step closer to this goal.

M-44s have been used by the elusive Wildlife Services within the <a href="https://www.usda.gov/">U.S. Department of Agriculture</a> beginning in the late 1960s. Their use was suspended by the <a href="https://www.epa.gov/">U.S. Environmental Protection Agency</a> in 1972 before being allowed again in 1975.

M-44s are often criticized for being indiscriminate killers that cause undue pain and suffering to its victims. In 2017 alone, Wildlife Services killed<a href="https://www.biologicaldiversity.org/news/press_releases/2018/wildlife-services-04-23-2018.php"> 2.3 million</a> animals, including non-target and <a href="http://www.earth.com/news/dogs-domesticated-america-10000-years/">domesticated species</a>.

[caption id="attachment_1872650" align="aligncenter" width="329"]<a href="https://www.earth.com/wp-content/uploads/2019/05/m44.jpg"><img class="size-full wp-image-1872650" src="https://www.earth.com/wp-content/uploads/2019/05/m44.jpg" alt="" width="329" height="285" /></a> M44 cyanide device, Image Credit: Guy Connolly, U.S. Department of Agriculture, National Wildlife Research[/caption]

The devices not only pose a threat to animals but humans as well. In<a href="https://www.idahostatesman.com/news/local/environment/article217956755.html"> March 2017</a>, a boy and his pet dog made national news when they encountered a M-44 device just 350 yards from their Idaho home. The boy had noticed the device, which looks like a pipe or water sprinkler, and tried to pick it up. The device then sprayed sodium cyanide onto the boy and his dog. The boy survived the incident but suffered from nausea and headaches. The family dog died in front of the young boy.

That’s one of the problems with the devices. To the untrained eye, M-44s look unassuming. Without proper signage, a person could easily accidentally set the device off. Even with displayed warnings, domesticated dogs risk setting the device off.

The agency mandates that warning signs are placed in all areas containing M-44 devices. Yet, the nonprofit group Predator Defense<a href="https://www.predatordefense.org/m44s.htm#stats"> says</a> they have repeatedly found a lack of warning signs in their investigations.

According to a U.S. Department of Agriculture <a href="https://www.aphis.usda.gov/publications/wildlife_damage/fs-m44-device.pdf">document</a>, “Wildlife Services certified applicators cannot place M-44s within 0.5 mile of occupied residences. A variance reducing that distance to 0.25 mile may be approved in instances where features of the property and landscape are such that potential for human or pet exposure to an M-44 is not probable. Wildlife Services notifies residents within 0.5 mile of M-44 locations.”

The family affected by the M-44 device in March 2017 say that they were never notified by Wildlife Services about the placement of the device.

Wildlife Services has been scrutinized for other shortcomings including the covering up of non-target killings.

An<a href="https://www.sacbee.com/news/investigations/wildlife-investigation/article2574599.html"> investigation</a> by the Sacramento Bee details an incident where an employee found a deceased golden eagle, a federally protected species, caught in a neck snare. The employee called his supervisor who then informed him to “go get a shovel and bury it and don't say nothing to anybody.”

Environmentalists and animal advocates warn that Wildlife Services has been operating with little oversight for years.

The ban on M-44s in Oregon is an important step towards ending the use of the devices and reining in Wildlife Services. The bill passed with almost unanimous support and <a href="https://myemail.constantcontact.com/FOR-IMMEDIATE-RELEASE--Oregon-has-banned-M-44--cyanide-bombs--.html?soid=1114995572448&amp;aid=wkPM0OOhFwg">environmentalists hope</a> the passage will encourage the 13 other states that currently use M-44s to ban their use.

At the federal level, attempts have been made to ban M-44s. In 2017, Representative Peter DeFazio introduced legislation to ban the use of sodium cyanide and Compound 1080 for predator control. Although the bill did not pass, similar legislation has since been<a href="https://www.congress.gov/bill/116th-congress/house-bill/2471/text?q=%7B%22search%22%3A%5B%22Chemical+Poisons+Reduction+Act%22%5D%7D&amp;r=1&amp;s=1"> reintroduced</a>.

Also in 2017, the U.S. Environmental Protection Agency<a href="https://www.biologicaldiversity.org/campaigns/carnivore_conservation/pdfs/EPA-2017-Petition-Response-11-16-18.pdf"> denied a petition</a> to cancel the registrations of M-44s.

Despite the lack of governmental action, there is growing opposition to M-44s among the public. A<a href="https://biologicaldiversity.org/w/news/press-releases/public-overwhelmingly-wants-ban-on-cyanide-bombs-2019-05-08/"> recent analysis</a> of public comments received by the U.S. Environmental Protection Agency on a proposal to renew M-44 device registrations found that over 99.9% of the 22,400 commenters supported a ban on the devices.

“It is far past time to eliminate these cruel killing devices altogether,” said Kelly Nokes, Shared Earth wildlife attorney for the Western Environmental Law Center in a<a href="https://biologicaldiversity.org/w/news/press-releases/public-overwhelmingly-wants-ban-on-cyanide-bombs-2019-05-08/"> press release</a>. “M-44s are an inhumane relic of the past and an unnecessary safety risk that have no place on our public landscape in 2019.”

The <a href="https://www.esa.int/">European Space Agency’s</a> (ESA) <a href="http://www.esa.int/Our_Activities/Observing_the_Earth/Living_Planet_Symposium">Living Planet Symposium</a> is well underway in Milan, Italy this week with over 4,000 people are in attendance. 

The symposium, held every three years, is the largest Earth observation conference in the world 

While not all satellites are used to observe and monitor Earth’s climate, surface temperature, and oceans, satellites are playing an increasingly important role in how researchers<a href="https://www.earth.com/news/cutting-edge-satellites-methane/"> gauge climate change</a> and work to tackle global warming. 

This year’s conference is not only dedicated to the Earth’s environment and climate but also the many new opportunities that satellites create for businesses, development, sustainability, and enrichment. 

Some of the topics slated to be presented at the symposium include how satellite data can open the door to innovations in artificial intelligence, technology, engineering, and science. 

“From space you don’t see borders, and this is the same for us – the countries of Europe are working together for a coherent approach that includes common goals and a full integration of space to bring the biggest benefits to society,” said General Jan Worner, ESA director, during a welcome speech that kicked off the conference. 

In a first for the ESA’s conference, over 2,000 children are presenting their own programs and work showcasing the importance and value that the younger generation has when it comes to science, innovation, and our planet’s future. 

“We are looking forward to hearing the latest scientific results. And, with ESA’s next ministerial council, Space19+, in November, we will also be talking about how we will take Earth observation into the future, particularly through innovation and partnerships,” said Josef Aschbacher, the ESA Director of <a href="http://www.esa.int/esapub/br/br114/br114ear.htm">Earth Observation Programmes</a> during a speech. “But crucially we need the engagement of young people, the scientists of tomorrow.”

<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.

<h2 class="wp-block-heading" id="h-when-earth-became-a-frozen-wasteland">When Earth became a frozen wasteland</h2>



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.

</div><figcaption class="wp-element-caption">Greenland is not sinking. In fact, it is the opposite.</figcaption></figure>



<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.

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

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.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes how record-breaking heat expressed itself around the world in 2022.



Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

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;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

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."
