<a href="https://www.earth.com/news/grapevines-could-offer-a-breakthrough-alternative-to-plastic-packaging/">Plastic</a> bags are everywhere, and too many slip into rivers and onto beaches. A new analysis finds that policies that either charge a small fee per bag or prohibit them outright cut the share of bags found during shoreline cleanups by 25 to 47 percent.



The study combed through hundreds of city, county, and state rules passed between 2017 and 2023. It matched those policies to more than 45,000 volunteer cleanups across the United States to see what actually changed on the ground.



<h2 class="wp-block-heading" id="h-who-ran-the-study">Who ran the study</h2>



The research was coauthored by <a href="https://www.udel.edu/academics/colleges/ceoe/departments/smsp/faculty/kimberly-oremus/" target="_blank" rel="noreferrer noopener">Kimberly L. Oremus</a> of the University of Delaware’s School of Marine Science and Policy (<a href="https://www.udel.edu/academics/colleges/ceoe/departments/smsp/" target="_blank" rel="noreferrer noopener">UDEL</a>). 



Oremus and her collaborator set out to measure litter, not just shopping behavior, so the results speak to what ends up in nature.



The team relied on citizen science, meaning trained volunteers recorded what they collected during beach, river, and lake cleanups. 



They drew on <a href="https://www.coastalcleanupdata.org/" target="_blank" rel="noreferrer noopener">TIDES</a>, a public database that stores those counts in one place so researchers can analyze patterns across time and place.



<h2 class="wp-block-heading" id="h-studying-plastic-bag-policies">Studying plastic bag policies</h2>



To isolate the effect of bag policies, the authors used a Difference-in-Differences (<a href="https://www.publichealth.columbia.edu/research/population-health-methods/difference-difference-estimation" target="_blank" rel="noreferrer noopener">DiD</a>) approach that compares places with and without new laws over the same period. 



That design helps rule out unrelated trends that affect everyone, such as national shifts in shopping or packaging.



The headline result is simple. In communities with full bans or fees, the share of <a href="https://www.earth.com/news/drinking-from-plastic-bottles-linked-to-high-blood-pressure-and-heart-problems/">plastic</a> bags in the litter mix fell relative to similar places without policies, and the decline grew in the years after a law took effect.



State level rules tended to be more reliable in the data than city or county policies. Effects looked similar along coasts and rivers, with hints of larger gains along lakes where winds and currents spread litter differently.



<h2 class="wp-block-heading" id="h-plastic-policy-fees-vs-bans">Plastic policy: Fees vs. bans</h2>



Fees change the default at every checkout and discourage taking a bag when you do not need one, which reduces both thin and thicker bag use.



Other <a href="https://www.gov.uk/government/publications/carrier-bag-charge-summary-of-data-in-england/single-use-plastic-carrier-bags-charge-data-for-england-2024-to-2025" target="_blank" rel="noreferrer noopener">evidence</a> points in the same direction outside the United States. England reports an almost 98 percent drop in single use carrier bags at major retailers since its charge began.



Policies that only restrict thin bags often allow thicker <a href="https://www.earth.com/news/agricultural-soil-is-now-the-worlds-biggest-plastic-dumping-ground/">plastic</a> labeled as reusable. 



Those partial bans showed the smallest and least precise effects in the analysis, which is consistent with shoppers substituting one kind of plastic for another.



Some states also pass preemption <a href="https://www.ncsl.org/environment-and-natural-resources/state-plastic-bag-legislation" target="_blank" rel="noreferrer noopener">laws</a> that block cities and counties from regulating bags at all. When local governments cannot act, the study’s data suggest statewide policies become especially important.



<h2 class="wp-block-heading" id="h-wildlife-and-entanglement">Wildlife and entanglement</h2>



The cleanup records include notes on animals found <a href="https://www.earth.com/news/microplastics-found-in-99-percent-sea-turtles-organ-tissue-reproductive-system/">entangled in debris</a>. 



In areas with bag policies, the presence of entangled animals dropped by roughly 30 to 37 percent, although the authors caution that the estimates are imprecise and more data are needed.



That finding aligns with what we know about <a href="https://www.nrdc.org/stories/single-use-plastics-101" target="_blank" rel="noreferrer noopener">single-use-plastics</a>. Thin bags linger in water and along shorelines, where they can snag, smother, or be eaten by turtles, birds, and fish.



Many studies track what happens at store checkouts, but fewer track what ends up outdoors. Shoreline cleanups offer a window into that last step in the chain from purchase to pollution.



Across the study period, the share of bags among collected items rose overall, but it rose less where bag laws existed. That pattern is exactly what you want to see if policies are slowing the flow of litter into the environment.



<h2 class="wp-block-heading" id="h-global-plastic-policy-steps">Global plastic policy steps</h2>



A small, universal fee is a simple tool that nudges behavior without banning choices. Full bans can work too, and the analysis shows both approaches reduce the share of <a href="https://www.earth.com/news/glass-bottles-contain-more-microplastics-than-plastic-containers/">plastic</a> bags found during cleanups.



The mix of policies should match local conditions. In places with more bag litter to begin with, impacts were largest, so targeting high problem areas with fast action can deliver quick gains.



Plastic bag rules are only one part of the picture. Negotiators from 175 countries are working toward a plastics treaty under <a href="https://www.unep.org/inc-plastic-pollution" target="_blank" rel="noreferrer noopener">UNEP</a> that could standardize action on a wider set of products and chemicals.



The study notes that bottles, caps, and other items did not decline when bag policies passed. That is a signal that targeted rules for other single use products would be needed to curb overall litter.



Adopt a modest fee or a full ban that applies across retail and restaurant settings, and keep the text simple so it is easy to enforce. Pair the policy with clear signs at checkout and with retailer reporting that tracks compliance.



Measure results in the same way the researchers did. Recruit volunteers, log items in TIDES, and watch how the litter mix changes year over year so the policy can be adjusted as needed.



The study is published in <a href="https://www.science.org/doi/10.1126/science.adp9274" target="_blank" rel="noreferrer noopener">Science</a>.

Studies confirm that a small tax definitely helps curb plastic pollution

Plastic bags are everywhere, and too many slip into rivers and onto beaches. A new analysis finds that policies that either charge a small fee per bag or prohibit them outright cut the share of bags found during shoreline cleanups by 25 to 47 percent. The study combed through hundreds of city, county, and state rules passed between 2017 and 2023.

A group of conservation scientists and policy makers led by University of Adelaide researchers are calling for global action to combat the illegal timber trade.

They say governments and organisations responsible for protecting wildlife and forests around the world and certification schemes need to "catch up with the science" and put in place policies and frameworks to ensure the legality of timber being logged and traded around the world.

Consumers too need to play their part in demanding verification of the origin and legality of the timber items they buy, they say.

Illegal logging is a major cause of forest degradation and loss of biodiversity, and accounts for between an estimated 15-30% of the global trade in timber, worth US$30-100 billion annually.

The scientists have published their recommendations in the journal BioScience - detailing the range of scientific methods available for timber identification and how they can be applied within the timber supply chain. The work is a collaboration between the University of Adelaide, timber-tracking specialists Double Helix Tracking Technologies, the USDA Forest Service, INTERPOL and other research and forestry organisations.

The recommendations stem from work commissioned by the United Nations Office of Drugs and Crime in support of the UN Resolution 23/1 from May 2014 on "strengthening a targeted crime prevention and criminal justice response to combat illicit trafficking in forest products, including timber".

"We now have the scientific capability to identify and track illegally logged timber through the supply chain through DNA profiling, DNA barcoding and other means," says lead author Professor Andrew Lowe, from the Environment Institute at the University of Adelaide. "But now we need the policy and regulatory framework to incorporate scientific verification."

"Illegal logging is a huge problem globally, driven as much by demand from consumer countries (including Australia) as from producer nations," says co-author Dr Eleanor Dormontt, who was employed by the UN to write the recommendations.

"Our paper is the first to bring together the various scientific methodologies available for timber identification and consider how best they can be applied in timber supply chains to promote legality.

"We are all implicit in the exploitation of the world's forests, and even the most conscientious consumer has a reasonably high chance of purchasing or otherwise handling illegal wood products in their lifetime. Scientists, policy makers, NGOs, graders, foresters and the general public all have a part to play.

"The reality is that changes to timber supply chains can be made to improve their transparency, legality and sustainability. We need a coordinated international effort to make it happen."

Add cockatoos to the growing list of  species capable of making tools.

Researchers from the University of Veterinary Medicine in Vienna and the University of Oxford have shown that Goffin's cockatoos can make and use elongated tools of appropriate shape and length out of different materials, suggesting that the birds can anticipate how the tools will be used.

Tool manufacture was once regarded as a defining feature of mankind, but it is now known that a variety of animal species use and make their own tools. In nature, some of the most striking cases of tool-related behavior are seen not just among close relatives of Homo sapiens, such as chimps and other primates, but among birds including crows, vultures and Galapagos finches.

In all cases, what makes this possible is possessing the right combination of heritable and acquired competencies, as well as being capable of a degree of individual creativity. Goffin's cockatoos is a particularly interesting example for scientists to study, as it has unlikely to have a repertoire of inherited tool-related skills and relies more on innovation and problem-solving.

Goffin's cockatoos, which is native to Indonesia, is neither known to use tools in the wild nor to have evolved related abilities for manipulating twigs for other purposes such as nest building. One bird, called Figaro, previously displayed the ability to spontaneously (ie without training) make tools by biting long splinters out of the wooden beams of its cage, which he then used to rake pieces of food that were otherwise out of reach. Three others have since followed, showing that making such tools is within the capacity of the species.

While impressive, these feats do not prove sensitivity to the need for the tools to be of a particular shape: because wood is fibrous, biting and pulling actions naturally split it into the long, narrow pieces necessary to succeed. If individuals are capable of anticipating the requirements of each tool, they should be able to produce functional instruments by displaying different actions and using different materials.

To test if the birds were in fact aiming to make elongated tools that could bridge a particular distance, the researchers gave them the problem of reaching a piece of food placed a few centimeters beyond a circular hole in the transparent wall of a box. They were given four different materials that required different manipulations to produce suitable tools: larch wood (already familiar to them), leafy beech twigs (which had to be trimmed to be functional), cardboard (which, lacking a fibrous structure, could be cut into any shape and length), and totally amorphous beeswax.

Dr Alice Auersperg, who heads the Goffin Laboratory in the Messerli Research Institute at the University of Veterinary Medicine, Vienna, said: 'While none of the birds succeeded in making tools out of beeswax, we found that at least some of them could make suitable tools from the three remaining materials.'

The successful parrots made well-shaped tools, even though each material required different manipulation techniques. To make tools out of larch wood, they bit the material once or twice and tore off the resulting splinter. To use the leafy twigs, they snapped off redundant leaves and side branches until what was left was usable. Finally, to make cardboard tools they simply cut what was necessary from the edge of the sheet provided.

Dr Auersperg added: 'To us, the tools made from cardboard were the most interesting ones, as this material was not pre-structured and required the birds to shape their tools more actively. They succeeded by placing a large number of parallel bite marks along the edge of the material like a hole punch, using their curved upper beak to cut the elongated piece out of the cardboard block after reaching a certain length. Interestingly, this length was usually just above or very close to the minimum length required to reach the food reward placed behind the barrier.'

Co-author Professor Alex Kacelnik, from the University of Oxford's Department of Zoology, said: 'Ultimately, we want to understand how animals think - namely, to produce the equivalent of explicit computer programs capable of doing what the birds do. We really don't know if the birds can picture in their minds an object that doesn't yet exist and follow this image as a template to build something new, or how their brains elicit the appropriate set of movements to organize their response to novel problems, but this is what we are trying to find out.

'Studying tool-making in species like Goffin's cockatoos, which does not make tools naturally, is especially revealing, as these birds cannot do it by following pre-programmed instructions evolved to solve this specific problem. These cockatoos, like other parrots, offer wonderful research opportunities: their intelligence is flexible and powerful, they can solve physical and logical problems, they can learn from watching the behavior of others, they can learn about the surrounding objects by playing - and now it seems plausible that they can imagine which object would allow them to solve a new problem and go on to build it. I am sure that they will keep surprising us.'

Goffin's cockatoos seen making sophisticated tools

Add cockatoos to the growing list of  species capable of...

President-elect Donald Trump is considering an oil billionaire and a North Dakota lawmaker for top posts as he moves to roll back President Barack Obama's environmental and energy policies and allow unfettered production of oil, coal and natural gas.
Trump has vowed to rescind "all job-destroying Obama executive actions" and pledges to sharply increase oil and gas drilling on federal lands while opening up offshore drilling in the Atlantic Ocean and other areas where it is blocked.
Topping Trump's to-do list is repealing the <a href="https://www.epa.gov/cleanpowerplan/clean-power-plan-existing-power-plants" target="_blank" rel="noopener">Clean Power Plan</a>, Obama's signature effort to limit carbon pollution from coal-fired power plants. The plan - the linchpin of Obama's strategy to fight climate change - is currently on hold awaiting a court ruling.
Trump also is targeting recent Obama administration efforts to reduce air and water pollution that have been opposed by Republicans and industries that profit from the extraction and burning of fossil fuels, including a rule to protect small streams and wetlands and ozone regulations designed to cut down on smog.
Those under consideration for energy secretary include Harold Hamm, an Oklahoma oil tycoon and leading proponent of fracking, and North Dakota Rep. Kevin Cramer, an early Trump supporter from a major oil drilling state, according to transition planning documents obtained by The Associated Press.
Venture capitalist Robert Grady, who worked in President George H.W. Bush's administration, is listed as a contender to lead both the Energy and Interior departments.
Cramer told reporters Monday he is happy to stay in Congress, especially "with a friend in the White House. And if another good friend like Harold Hamm would become secretary of energy, I'd feel like I won the lottery."
A coalition of conservative states has challenged both the Clean Power Plan and the water rule, which expanded the definition of waters protected under the <a href="https://www.epa.gov/laws-regulations/summary-clean-water-act" target="_blank" rel="noopener">Clean Water Act</a> to smaller non-navigable waters and seasonal tributaries.
The administration says the rule would safeguard drinking water for 117 million people, but Republicans and some Democrats representing rural areas say the regulations are costly, confusing and amount to a government power grab. Federal courts have put the rules on hold as judges review lawsuits.
Trump also is likely to move quickly to approve the Keystone XL oil pipeline from Canada, which Obama rejected last year. Trump highlighted the project at a campaign stop in Florida last month and listed it among his top priorities for the first 100 days of his administration.
Karen Harbert, president and CEO of the U.S. Chamber of Commerce's Institute for 21st Century Energy, said Trump can and will move quickly to overturn Obama's executive orders. From there, he will likely move to approve a new five-year plan that vastly expands offshore drilling and lift a moratorium on coal leasing on federal lands.
"If you have a good offense and a good defense you will win," Harbert said. Whoever Trump picks for key jobs will share his goals of "moving fast, changing the process which is not working now and getting things done," she said.
Obama said Monday that Trump should be in no hurry to make changes, citing U.S. progress on reducing carbon emissions even as the price of gasoline hovers nears $2 a gallon. Trump and his team "may want to take the country in a significantly different direction, but they've got time to consider what exactly they want to achieve," Obama said at a news conference.
Environmental groups don't plan to make Trump's job easy.
"We intend to fight like mad, both in the courts and in the streets, to resist any rollbacks by the Trump administration," said Michael Brune, executive director of the Sierra Club.
Some of those protests have already begun. Groups opposing the construction of an oil pipeline through the Midwest are planning more than 200 protest actions across the country Tuesday.
The Army Corps of Engineers said Monday it wants more study and tribal input before approving the $3.8 billion Dakota Access pipeline from North Dakota to Illinois. The Standing Rock Sioux says the pipeline threatens its drinking water and cultural sites.
Even as they gear up to oppose Trump, Brune said environmentalists may find some common ground with the president-elect. Renewable energy sources such as wind and solar power not only help fight climate change but are creating thousands of new jobs across the country, he said.
"If President-elect Trump is looking for a stimulus in energy he will find it in the solar and wind industries," Brune said.
Trump has said tax credits and other subsidies for wind and solar power "distort" the market, but says the U.S. should "encourage all facets of the energy industry," including wind and solar power, as a way to achieve energy independence.

Global carbon emissions flattened out in 2015, and are predicted to rise minimally in 2016, marking three full years of very low growth, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project.

The projected rise of only 0.2% for 2016 marks a clear break from the rapid emissions growth of 2.3% per year in the decade to 2013, with just 0.7 per cent growth seen in 2014.

The new data is published in the journal Earth System Science Data. It shows emissions growth remained below 1 per cent despite GDP growth exceeding 3 per cent.

Decreased use of coal in China is the main reason behind the 3-year slowdown.

Prof Corinne Le Quéré, Director of the Tyndall Centre at UEA who led the data analysis, said: “This third year of almost no growth in emissions is unprecedented at a time of strong economic growth. This is a great help for tackling climate change but it is not enough. Global emissions now need to decrease rapidly, not just stop growing.”

China – the biggest emitter of CO2 at 29 per cent – saw emissions decrease by 0.7 per cent in 2015, compared to growth of more than 5 percent per year the previous decade. A further reduction of 0.5 per cent is projected for 2016, though with large uncertainties.

The USA, the second biggest emitter of CO2 at 15 per cent, also reduced its coal use while increasing its oil and gas consumption and saw emissions decrease 2.6 per cent last year. USA emissions are projected to decrease by 1.7 per cent in 2016.

The EU’s 28 member states are the third largest emitter causing 10 per cent of emissions. The EU’s CO2 emissions went up 1.4 percent in 2015, in contrast with longer term decreases.

India contributed 6.3 per cent of all global CO2 emissions, with their emissions increasing 5.2 percent, in 2015 continuing a period of strong growth.

Although the break in emissions rise ties in with the pledges by countries to decrease emissions until 2030, it falls short of the reductions needed to limit climate change well below 2 degrees Celsius.

Prof Le Quéré said: “If climate negotiators in Marrakesh can build momentum for further cuts in emissions, we could be making a serious start to addressing climate change.”

The Global Carbon Budget analysis also shows that, in spite of a lack of growth in emissions, the growth in atmospheric CO2 concentration was a record-high in 2015, and could be a record again in 2016 due to weak carbon sinks.

Prof Le Quéré said: “Part of the CO2 emissions are absorbed by the ocean and by trees. With temperatures soaring in 2015 and 2016, less CO2 was absorbed by trees because of the hot and dry conditions related to the El Niño event. Atmospheric CO2 levels have exceeded 400 parts per million (ppm) and will continue to rise and cause the planet to warm until emissions are cut down to near zero.”

The Global Carbon Project’s estimation of global CO2 emissions and their fate in the atmosphere, land and ocean is a major effort by the research community to bring together measurements, statistics on human activities, with analysis of model results.

Prof Le Quéré stressed the need for reporting such as the Global Carbon Budget to inform decisions and actions on how to respond to climate change.

Dr Glen Peters of the Center for International Climate and Environmental Research in Norway, who co-authored the analysis, said: “Emissions growth in the next few years will depend on whether energy and climate policies can lock in the new trends, and importantly, raise the ambition of emission pledges to be more consistent with the temperature goals of the Paris Agreement.”

A Canadian natural gas plant could post more risk to salmon than previously believed if the project is allowed to go ahead, according to a new study.

The new research, conducted at the proposed site of a liquified natural gas plant on the Skeena River, found that the area is a popular destination for salmon. The fish spend a month or more in the spot to feed and grow before braving the trip out to sea, the study reported.

Dr. Jonathan Moore of <a href="https://www.sfu.ca/">Simon Fraser University</a>, who led the study, said the research shows the Skeena River estuary may be more valuable salmon habitat than originally believed. 

A previous marine fish survey, conducted on behalf of the natural gas plant project by <a href="http://www.stantec.com/">Stantec Consulting</a>, found the area to be a “low value” fish habitat. <a href="http://www.dfo-mpo.gc.ca/index-eng.htm">Fisheries and Oceans Canada</a>, the federal agency that manages Canada’s waterways, disagreed with Stantec’s conclusion, but the international energy coalition spearheading the gas plant project said that negative effects of construction could be mitigated.

The research team led by Moore used chemical signatures of sulfur, carbon and nitrogen left behind by fish as a sort of “chemical clock” to figure out how long they stayed in the estuary before heading out to sea.

The scientists found that about a quarter of Chinook salmon took a break in the estuary for 33 days, pink salmon vacationed about 30 days, and coho lingered for 22. Sockeye salmon only stayed in the estuary for about five days.

Knowing how long each species stayed in the stopover location would help environmental managers decide how important the area is to the fish, Moore said.

The research could cause another wrinkle for the gas plant, which is facing three lawsuits lodged by environmental groups and indigenous Canadians. Two of the three suits, filed in late October, laid out environmental activists’ concerns over the project’s environmental assessment process and the plant’s potential greenhouse gas emissions. 

The third, filed by the Gitanyow and Gitwilgyoots First Nations, claimed that indigenous Canadians were not well included in the project’s approval process.

Currently, the <a href="http://www.ceaa.gc.ca/default.asp?lang=en&amp;n=d75fb358-1">Canadian Environmental Assessment Agency</a> is allowing the project to proceed, provided it meets about 190 conditions set by the agency.

The salmon study was published on November 9 in the journal <a href="http://www.int-res.com/journals/meps/meps-home/">Marine Ecology Progress Series</a>.

Is one type of electric car better than another? That’s what researchers from <a href="https://www.stanford.edu/">Stanford University</a> and the <a href="https://www.tum.de/">Technical University of Munich</a> set out to determine when they compared electric cars that run off of hydrogen gas fuel cells to those that use rechargeable batteries.

According to the researchers, <a href="http://www.sciencedirect.com/science/article/pii/S0360544216311173">their study</a> offered an answer: battery-powered cars are both cheaper and more energy efficient for the immediate future, they said.

The study sought to help communities decide which type of electric car would be a better long-term investment, according to lead author Markus Felgenhauer, a doctoral student at the Technical University of Munich who previously studied at Stanford’s <a href="http://gcep.stanford.edu/">Global Climate and Energy Project</a>. 

To do that, the researchers considered how large-scale adoption of either battery-powered or fuel cell vehicles could affect community infrastructure. They focused their attention on Los Altos Hills, a small city in California, as a sort of case study to test their theories.

According to the research team, battery-powered electric cars are more economical because they are currently cheaper to buy, and can be charged by plugging into the existing electrical grid, no matter what type of energy a city uses.

Hydrogen fuel cells, however, must be refilled with hydrogen. The cost of installing electrolyzers that can convert solar energy or electricity from the grid to hydrogen would be a steep initial cost. 

Some have suggested that solar power could be converted and stored as hydrogen, and the excess could be used to power buildings, the research team said, but they found that not enough hydrogen is produced from solar power yet to make that a realistic goal. 

Taking in all of the costs of infrastructure, making batteries, and producing solar panels and electrolyzers, the battery-powered cars are the most cost effective at the moment, they said. 

Even so, if hydrogen fuel cell vehicles were much cheaper than battery-powered vehicles, they might be the better choice, Felgenhauer said. Currently, they are more expensive.

The study found that both types of vehicles could reduce overall carbon dioxide emissions.

The study was published in the journal <a href="http://www.journals.elsevier.com/energy">Energy</a>.

Fishing sustainably would increase fish catches by 57% in European waters, a marine conservation group said Tuesday.
<a href="http://www.oceana.org" target="_blank" rel="noopener">The Oceana environmental group</a> says scientists believe catches of haddock, cod, herring and sardine in the Atlantic could increase by at least 300 percent.
Group spokeswoman Maria Cornax said Tuesday there was "no excuse" not to start fishing sustainably.
"This is actually meant to help the fishery industry," she said. "They can get increased profits."
The European Commission, executive arm of the EU, has proposed maintaining or increasing the fishing quotas for 42 species which are rated in good health, and reduce catches for 28 stocks which are faring poorly. It said it based its suggestion on advisory bodies including the Copenhagen-based International Council for the Exploration of the Sea.
Oceana's research, which it billed as "the most comprehensive overview so far," was based on 397 stocks compared to around 150 monitored by the Commission.
Oceana published its findings before next month's EU meeting to set the 2017 fishing limits in the North Sea. Oceana said 85 percent of stocks were now "in an unhealthy state."
The study was led by a Germany-based <a href="http://www.geomar.de/en/" target="_blank" rel="noopener">GEOMAR Helmholtz Center for Ocean Research</a>.
Last month, the EU agreed to set tougher cod catch quotas in the western part of the Baltic Sea, but stayed well above targets sought by scientists who pushed for a cut of about 90 percent, and environmentalists who called for a temporary stop. EU fisheries ministers agreed on a 56 percent quota cut for the cod.

Global temperatures are soaring toward a record high this year, the U.N. weather agency said Monday, while another report showed emissions of a key global warming gas have flattened out in the past three years.
The reports injected a mix of gloom and hope at U.N. climate talks in Marrakech this week.
"Another year. Another record. The high global temperatures we saw in 2015 are set to be beaten in 2016," said Petteri Taalas, the head of the World Meteorological Organization.
WMO's preliminary data through October showed global temperatures, boosted by the El Nino phenomenon, are 1.2 degrees Celsius (2.2 degrees Fahrenheit) above pre-industrial levels.
That's getting close to the limit set by the global climate agreement adopted in Paris last year. It calls for limiting the global temperature rise since the industrial revolution to 2 degrees C or even 1.5 degrees C.
WMO said 16 of the 17 hottest years have occurred this century. The only exception was 1998, which was also an El Nino year.
Taalas said parts of Arctic Russia saw temperatures soaring 6-7 degrees C above average. "We are used to measuring global temperature records in fractions of a degree, and so this is different," he said.
Environmental groups and climate scientists said the report underscores the need to quickly reduce emissions of carbon dioxide and other greenhouse gases blamed for warming the planet.
Another report released Monday delivered some positive news, showing global CO2 emissions have flattened out in the past three years. However, the authors of the study cautioned it's unclear whether the slowdown, mainly caused by declining coal use in China, is a permanent trend.
"It is far too early to proclaim we have reached a peak," said co-author Glen Peters, a senior researcher at the Center for International Climate and Environmental Research in Oslo.
The study, published in the journal Earth System Science Data, says global CO2 emissions from fossil fuels and industry are projected to grow just 0.2 percent this year.
That would mean emissions have leveled off at about 36 billion metric tons in the past three years even though the world economy has expanded, suggesting the historical bonds between economic gains and emissions growth may have been severed.
"This could be the turning point we have hoped for," said David Ray, a professor of carbon management at the University of Edinburgh, who was not involved with the study. "To tackle climate change those bonds must be broken and here we have the first signs that they are at least starting to loosen."
Chinese emissions were down 0.7 percent in 2015 and are projected to fall 0.5 percent in 2016, the researchers said, though noting that Chinese energy statistics have been plagued by inconsistencies.
Peters said it's unclear whether the Chinese slowdown was due to a restructuring of its economy or a sign of economic instability, but the unexpected emissions reduction "give us hope that the world's biggest emitter can deliver much more ambitious emission reductions."
China, which accounts for almost 30 percent of global carbon pollution, pledged to peak its emissions around 2030 as part of the climate pact adopted in Paris last year. Many analysts say China's peak is likely to come much earlier - and may already have occurred.
"A few more years of data is needed to confirm this," said Bill Hare of Climate Analytics.
Even if China's emissions have stabilized, growth in India and other developing countries could push global CO2 levels higher again. India's emissions rose 5 percent in 2015, the study said.
The election of Donald Trump as president of the United States - the world's No. 2 carbon polluter - could also have an impact.
U.S. emissions fell 2.6 percent last year and are projected to drop 1.7 percent this year, as natural gas and renewables displace coal in power generation, the study showed. But it's unclear whether those reductions will continue under Trump, who has pledged to roll back the Obama administration's environmental policies, including the Clean Power Plan to reduce carbon pollution from power plants.
Obama's climate envoy, Jonathan Pershing, said Monday that China and other countries would move forward on climate action even if the U.S. reverses course under Trump.
"I'm hearing the same from the Europeans," he said. "I'm hearing the same from the Brazilians. I'm hearing the same from Mexico, and from Canada, and from smaller nations like Costa Rica and from Colombia."
Some researchers stressed that it's not enough for global emissions to stabilize, saying they need to drop toward zero for the world to meet the goals of the Paris deal.
"Worryingly, the reductions pledged by the nations under the Paris Agreement are not sufficient to achieve this," said climate scientist Chris Rapley of University College London.

Global temperatures in 2016 set to break heat record

Global temperatures are soaring toward a record high this year,...

China and other countries will stay committed to the Paris Agreement on climate change, irrespective of what the next U.S. administration decides to do, the outgoing U.S. climate envoy said Monday.
Jonathan Pershing told reporters at U.N. climate talks in Morocco he doesn't know what President-elect Donald Trump's "outlook" on climate policy will be. But Pershing said his Chinese counterpart, Xie Zhenhua, told him that China intends to move ahead regardless.
"Of course they are going to move forward," he said. "I'm hearing the same from the Europeans. I'm hearing the same from the Brazilians. I'm hearing the same from Mexico, and from Canada, and from smaller nations like Costa Rica and from Colombia."
Trump has called global warming a "hoax" on social media and promised during his campaign to "cancel" the Paris deal adopted last year. But many countries are hoping he will change his mind once in office.
"It is in the interest of the United States to deliver clean energy policies," said European Union Climate Commissioner Miguel Arias Canete.
Canete said he didn't want to speculate on "worst-case scenarios" such as the U.S. withdrawing from the Paris Agreement - the first in which all countries have agreed to take action on climate change.
"I prefer to be an optimist," Canete said.
He dismissed a proposal by former French president and current presidential candidate Nicolas Sarkozy for a carbon tax on American goods imported to the EU if the U.S. withdraws from the climate change deal.
"The European Commission is not thinking of making a proposal on that issue," Canete said.

The moon is a familiar sight in our sky, brightening dark nights and reminding us of space exploration, past and present. But the upcoming supermoon — on Monday, Nov. 14 — will be especially “super” because it’s the closest full moon to Earth since 1948. We won’t see another supermoon like this until 2034.

The moon’s orbit around Earth is slightly elliptical so sometimes it is closer and sometimes it’s farther away. When the moon is full as it makes its closest pass to Earth it is known as a supermoon. At perigree — the point at which the moon is closest to Earth — the moon can be as much as 14 percent closer to Earth than at apogee, when the moon is farthest from our planet. The full moon appears that much larger in diameter and because it is larger shines 30 percent more moonlight onto the Earth.

The biggest and brightest moon for observers in the United States will be on Monday morning just before dawn. On Monday, Nov. 14, the moon is at perigee at 6:22 a.m. EST and “opposite” the sun for the full moon at 8:52 a.m. EST (after moonset for most of the US).

If you’re not an early riser, no worries. “I’ve been telling people to go out at night on either Sunday or Monday night to see the supermoon,” said Noah Petro, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter (LRO) mission. “The difference in distance from one night to the next will be very subtle, so if it’s cloudy on Sunday, go out on Monday. Any time after sunset should be fine. Since the moon is full, it’ll rise at nearly the same time as sunset, so I’d suggest that you head outside after sunset, or once it’s dark and the moon is a bit higher in the sky. You don’t have to stay up all night to see it, unless you really want to!”

This is actually the second of three supermoons in a row, so if the clouds don’t cooperate for you this weekend, you will have another chance next month to see the last supermoon of 2016 on Dec. 14.

NASA scientists have studied the moon for decades. A better understanding of our moon helps scientists infer what is happening on other planets and objects in the solar system. “The moon is the Rosetta Stone by which we understand the rest of the solar system,” Petro said.

LRO has been mapping the moon’s surface and capturing high resolution images for more than seven years. Extensive mapping of the moon aids scientists in understanding our planet’s history, as well as that of planetary objects beyond the Earth-moon system.

“Because we have the Apollo samples, we can tie what we see from orbit to those surface samples and make inferences about what has happened to the moon throughout its lifetime,” Petro said. “The samples tell us how old certain lunar surfaces are, and based on the number of impact craters on those surfaces, we can estimate the ages of the rest of the moon. Furthermore, we can then apply those models to estimate the ages of surface on other planets in our solar system — all by studying the moon!”

When it comes to carbon storage, scientists have put a price tag on the value of mangrove forests in South Florida's Everglades -- and it's in the billions.

Mangrove forests absorb carbon dioxide, and much of that carbon remains trapped in the trees' biomass. Based on a scientific cost estimate, the stored carbon is worth between U.S. $2 billion and $3.4 billion. The billion-dollar price tag reflects the cost of restoring freshwater flow to areas that need it most, preserving the Everglades' mangroves.

That's a relatively small price when considering the cost to society if, rather than being stored, the carbon were released into the atmosphere, according to researchers at Florida International University (FIU).

Their results are published in the journal Environmental Science and Policy. The study was funded by the National Science Foundation's (NSF) Water, Sustainability and Climate Program and the NSF Florida Coastal Everglades Long-Term Ecological Research (LTER) site.

"If there isn't enough freshwater flowing through the Everglades, we may eventually lose some of the mangroves," said Mahadev Bhat, a scientist at FIU and co-author of the journal paper. "Once you let stored carbon out, that same carbon can lead to increased global warming and cost society a lot more."

In addition to removing excess carbon dioxide from the air, mangroves provide other benefits, including flood control, storm protection and good water quality.

"This finding is an excellent example of how research at long-term ecological research sites can inform management and policy decisions and help in making wise choices, in this case, how to mitigate the effects of increasing carbon dioxide in the atmosphere," said David Garrison, LTER program director in NSF's Division of Ocean Sciences.

The mangrove forests of the Everglades are the largest in the continental United States. Although protected, Everglades mangroves are affected by sea level rise, hurricanes, alterations in water flow and other changes.

"While our understanding of the Everglades is strengthened by this study, we need to remember that threats to this valued resource come from both saltwater intrusion and sea level rise," said Tom Torgersen, director of NSF's Water Sustainability and Climate program. "Management and policy decisions need to reflect the value of the Everglades, as well as the issues facing Florida."

According to the FIU researchers, preventing the loss of stored carbon in mangroves could become a critical component of the nation's climate change mitigation strategies.

"Having an inventory of the stored organic carbon and its potential economic value is key to designing strategies that secure funding for conservation and research work," said Meenakshi Jerath, lead author of the paper and a researcher at FIU's Extreme Events Institute. "It could, more importantly, further awaken public interest in and understanding of mangroves' socioeconomic importance."

Added John Schade, LTER program director in NSF's Division of Environmental Biology: "This research is a reminder of the valuable services mangroves provide, and the global benefits that can come from restoring and preserving them."

The study was conducted in collaboration with researchers at Louisiana State University and the NASA Jet Propulsion Laboratory.

On Election Day, 56 percent of California voters gave their approval to Proposition 64, which legalized marijuana. 

That means California (along with Nevada and Massachusetts) will be joining the five states where recreational pot is already legal: Colorado, Washington, Oregon, and Alaska.

So what does this mean for California residents?

First off, not all of the changes will come overnight. According to Amanda Reiman of the <a href="http://www.drugpolicy.org/">Drug Policy Alliance</a>, the group that helped to write the initiative, it’s not yet legal to buy marijuana without a medical card, and it probably won’t be until sometime in 2018. 

The state still needs to hammer out a lot of regulations, she said, so outside of areas that already have large and well-organized medical marijuana networks, there may be a wait.

However, as of November 9, the day after the election, Californians over the age of 21 can now possess, use, share and grow marijuana. Someone who already grows cannabis with a medical card can give a plant to a friend, or offer them marijuana that’s ready to use. But it cannot be bought or sold, even between acquaintances, until legal shops are cleared to open and state regulations on sales are in place.

 Other things to know:

Where to grow cannabis

Marijuana doesn’t have to be grown in your home in some places, but many areas require that it be grown in a “enclosed and secure” space, and a few cities do have ordinances barring outdoor cultivation. That makes growing indoors the easiest way to obey existing laws.

How much you can grow

Each household is permitted to have no more than six plants at one time, no matter how many people live there. 

Where pot can be smoked or ingested

Weed cannot be used while driving, and it cannot be taken across state lines or on a plane. People under the age of 21 are not permitted to ingest or smoke cannabis anywhere. Adults may not ingest or smoke in public. Prop. 64 does allow for licensed on-site use at some businesses, but it’s unlikely licenses will be issued any time soon. In the meantime, private homes are the only legal place to consume marijuana at this time. 

Criminal penalties

Starting on November 9, the penalties for using marijuana in California changed. Under the new law:
<ul>
 	<li style="font-weight: 400;">Some of those with criminal records related to pot possession will be able to have their records expunged, and if they are still serving a sentence, may be able to get an early release. However, this will almost certainly be limited only to activities which are now legal, not to those still illegal under the new law.</li>
 	<li style="font-weight: 400;">Juveniles (those under 18) will now be sentenced with counseling and community service if they are found to be in possession of pot, rather than jail time. </li>
</ul>

<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.

<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>.

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.

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>.

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.

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.

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."
