From coastlines to capital cities, healthcare workers are warning about the immediate need for a treaty to end plastic pollution.



The danger of a global health disaster is at its highest level as United Nations-led negotiations to form a plastic treaty continue to remain dead-locked due to ongoing disputes.



Plastic pollution not only endangers human health, but threatens to harm our planet itself. Without decisive action, the consequences could be irreversible.



<h2 class="wp-block-heading" id="h-plastic-treaty-negotiations">Plastic treaty negotiations</h2>



At the forefront of this urgent plea for action are researchers from the Revolution Plastics Institute at the <a href="https://www.port.ac.uk/" target="_blank" rel="noreferrer noopener">University of Portsmouth</a>.



The experts recently spotlighted the matter in an article published by the British Medical Journal, following their participation in the plastic treaty negotiations in Busan last December.



The negotiations concluded without any agreement being reached, and this pushed further discussions into 2025.



<h2 class="wp-block-heading" id="h-skyrocketing-plastic-production">Skyrocketing plastic production</h2>



With global annual <a href="https://www.earth.com/news/plastic-production-increases-create-identical-plastic-pollution-increase/" target="_blank" rel="noreferrer noopener">plastic production</a> currently at an alarming 400 million tonnes and expected to double by 2040, the scientists see health care professionals playing an increasingly crucial role.



The need of the hour, they say, is for more robust scientific evidence showing the impact of plastic pollution on human health. 



Such data will fortify the treaty process and guide the creation of targeted policies to reduce human exposure to plastic pollution.



"The treaty to end plastic pollution represents a historic opportunity to protect human health. If the treaty is to meet this challenge, its text must include specific measures to mitigate the health effects of plastic pollution, human health targets and metrics to measure progress towards improved health outcomes," noted Professor Steve Fletcher, the director of the Revolution Plastics Institute.



<h2 class="wp-block-heading" id="h-human-health-versus-plastic-pollution">Human health versus plastic pollution</h2>



The article focuses on two critical health concerns linked to plastic pollution. 



First, there are the omnipresent <a href="https://www.earth.com/news/microplastics-are-infiltrating-the-human-body-even-the-brain/" target="_blank" rel="noreferrer noopener">microplastics</a> - tiny particles found in the air we breathe, waterways, polar ice, soil, and in our food.



Humans are constantly ingesting, inhaling, and absorbing these particles. They have been detected in numerous organs and tissues, from the brain and blood to the placenta and liver. Microplastics have even been found in breast milk and semen.



<h2 class="wp-block-heading" id="h-open-burning-of-plastic-waste">Open burning of plastic waste</h2>



The other critical issue is the harmful health effects of inhaled <a href="https://www.earth.com/news/microplastics-can-make-other-pollutants-more-toxic/" target="_blank" rel="noreferrer noopener">toxic pollutants</a> that are released from the open burning of plastic waste. This danger is particularly acute in areas with deficient waste management systems.



The emissions from such open burns, which are loaded with toxic chemicals, particulate matter, and microplastics, are associated with serious health conditions. These include respiratory infections, <a href="https://www.earth.com/news/steep-rise-in-cardiovascular-disease-expected-in-the-u-s/" target="_blank" rel="noreferrer noopener">cardiovascular diseases</a>, and chronic conditions like COPD (chronic obstructive pulmonary disease).



Dr. Cressida Bowyer, the Deputy Director of the Revolution Plastics Institute, has extensively studied the perils of open burning of plastic waste. 



"With 16% of global municipal waste burned openly, rising to 40–65% in low-and middle-income countries, vulnerable populations bear the brunt of this crisis. The toxic fumes from burning plastic are a silent but deadly contributor to global health burdens. Urgent action is needed to eliminate this dangerous practice and protect public health," she warned.



<h2 class="wp-block-heading" id="h-vulnerable-populations-are-affected-the-most">Vulnerable populations are affected the most</h2>



The longer the world waits to finalize a binding plastic <a href="https://www.earth.com/news/global-plastics-treaty-countries-with-nothing-to-lose-delayed-progress/" target="_blank" rel="noreferrer noopener">treaty</a>, the more devastating the health impacts of plastic pollution will become.



Studies show that vulnerable populations, particularly in low- and middle-income countries, are disproportionately exposed to the harmful effects of plastics. 



This disparity is most apparent in regions with inadequate waste management systems, where open burning of plastic waste is rampant and environmental contamination intensifies daily.



Beyond its environmental toll, plastic pollution worsens global health inequalities. Microplastics and toxic chemicals from mismanaged plastic waste seep into the food chain, water sources, and also into the air.



Toxic emissions, especially in urban areas, have been linked to respiratory diseases such as cancer and cardiovascular disorders.



<h2 class="wp-block-heading" id="h-treaty-needed-to-end-plastic-pollution">Treaty needed to end plastic pollution</h2>



Health experts warn that without the necessary steps of action, these health crises will intensify and spread aggressively, straining health systems and threatening the health of future generations.



But dealing with plastic pollution is not just an environmental issue; it is an important step to ensuring the global public's health.



The message is clear. As responsible stewards of the planet and protectors of human health, it's time for all health professionals to take a determined stand against the harms of plastic pollution.

Imagine 30 million gallons of raw sewage dumped into the nation’s second-largest estuary, just off the shores of a major U.S. city and its largest park. That’s the situation in <a href="https://www.earth.com/news/kayakers-prepare-to-meet-shell-oil-rig-in-seattle/">Seattle</a> since an electrical failure resulted in the catastrophic spill of human waste into Puget Sound that occurred February 9-16, according to the <a href="https://www.ap.org/en-us/">Associated Press</a>.

Local authorities say that the accident damaging the underground network of pumps, motors, electric panels and other system components has been fixed and that no raw sewage has escaped since mid-February. They also say that they’ve been working 24 hours a day to effect repairs and clean up the damage.

However, the facility is currently only partially treating waste at this point before dumping it into the Sound.

“It has been a disaster, and we're not out of it yet,” said Jeanne Kohl-Welles, a King County councilwoman, in an <a href="https://www.ap.org/en-us/">Associated Press</a> interview. “We still don't know really what went wrong. We've got to get a handle on it. I'm very concerned about the environment, the effects on marine life in the sound, (and) public health.”

Kohl-Welles’s district includes the hobbled West Point Treatment Plant, which is located next to the city’s largest public park.

So far, damage and cleanup costs have exceeded $25 million and the treatment plant expects to not be finished until the end of April.

As for the long-term damage, untreated waste can adversely affect the health of humans and marine life through the release of chemicals and germs. It could also make the region’s popular shellfish risky to eat.

“Anytime pollution goes into the sound, it's a concern," Sheida Sahandy, who directs the Puget Sound Partnership, told the <a href="https://www.ap.org/en-us/">Associated Press</a>. PSS is the state agency responsible for cleaning up the sound.

The spill also gives a bloody nose to the reputation of the region for its clean waterways and environmental concerns.

Could man-made climate change be affecting the planetary airstreams that trigger extreme weather? An international team of climate scientists think so. 

The scientists – from the <a href="https://www.pik-potsdam.de/pik-frontpage">Potsdam Institute for Climate Impact Research</a> (PIK), <a href="http://www.psu.edu/">Pennsylvania State University</a>, and <a href="https://www.vu.nl/en/">Vrije Universiteit Amsterdam</a> – have linked “stalling” giant airstreams to human activity.

“The unprecedented 2016 California drought, the 2011 U.S. heatwave and 2010 Pakistan flood as well as the 2003 European hot spell all belong to a most worrying series of extremes,” said Dr. Michael Mann of Penn State, the study’s lead author, in a press release. “The increased incidence of these events exceeds what we would expect from the direct effects of global warming alone, so there must be an additional climate change effect. In data from computer simulations as well as observations, we identify changes that favor unusually persistent, extreme meanders of the jet stream that support such extreme weather events.”

The data point to human activity as a culprit in the unusual airstream activity, Mann said.

Extreme weather, from drought to flooding to heatwaves, occurs when the climate in an area gets “stuck” on otherwise normal weather, co-author Dr. Stefan Rahmstorf of PIK said. Dry, hot days or rain without a break can cause problems, he said.

“This occurs under specific conditions that favor what we call a quasi-resonant amplification that makes the north-south undulations of the jet stream grow very large,” Rahmstorf said. “It also makes theses waves grind to a halt rather than moving from west to east.”

The airstreams are powered by the gap in temperature between the polar regions and the Equator, he explained. The poles – especially the Arctic – are warming more quickly than equatorial regions, and that affects the movement of the airstreams, Rahmstorf said.

Another factor is that the average surface temperature over land masses is rising faster than over oceans. This also affects the airstreams, Rahmstorf said.

The team of scientists used temperature data recorded since 1870 to reach their conclusions. They found that a particular combination of temperature factors cause the planetary airstreams to “stall.” They also found that this concurrence of conditions had increased by 70 percent since the Industrial Revolution began. 

The pace has picked up even more in the past four decades, the team found.

“The more frequent persistent and meandering jetstream states seems to be a relatively recent phenomenon, which makes it even more relevant,” said Dr. Dim Coumou of VU Amsterdam. 

The researchers acknowledged that the study is only beginning to tackle how climate change and human activity may influence the planetary airstreams to cause extreme weather events.

“We certainly need to further investigate this – there is some good evidence, but also many open questions,” Coumou said. “In any case, such non-linear responses of the Earth system to human-made warming should be avoided.”

The study will be published in the journal <a href="http://www.nature.com/articles/srep45242">Scientific Reports</a>.

The world changed dramatically beginning some 35 million years ago in what is now Australia. For starters, the entire island nation broke off from <a href="https://www.earth.com/news/antarctica-sets-record-high/">Antarctica</a>, and at about the same time, temperatures dropped globally. The freeze resulted in a mass extinction event that drew the interest of modern-day scientists from <a href="http://www.anu.edu.au/">Australian National University</a>.

The ANU researchers used molecular evolutionary studies and fossil records to study a species of pygopodoid geckos that became extinct due to the abrupt climate change.

“The dramatic shift to colder and drier climates likely resulted in rapidly changing Australian habitats, which hugely impacted the animals that inhabited them,” said Ian Brennan, the lead researcher of the study and a PhD student at the ANU Research School of Biology. “Our research provides evidence that rapid shifts in climate may have profound and long-lasting effects on global biodiversity.”

Species of pygopodoid geckos died off in a mass extinction event caused by the freezing temperatures. But over time new species of the hardy reptile adapted to the changing climate in a number of ways once the effects of the big chill wore off and the landscape turned to heated deserts some ten million years ago.

For instance, the reptiles dodged the radiant heat by becoming nocturnal and they developed rugged skin and scales to defend against water loss.

The study proved that climate change affects biodiversity in long-term and dramatic ways. So how will Earth and its inhabitants change to meet the conditions to come under this next cycle of global environmental change?

The ANU study was published earlier this month in the journal Evolution.

Carbon dioxide is a greenhouse gas. It traps heat in the atmosphere, thus making it the main culprit for climate change. But what if science could find a way to convert CO2 to methanol?

On the face of it, that doesn’t look like much of a trade off. Methanol is a chemical that can cause blindness, coma and even death to humans. But when handled carefully, it’s a valuable substance in the production of paint, <a href="https://www.earth.com/news/first-evidence-that-deep-sea-animals-are-ingesting-plastics/">plastics</a> and even explosives.

And now researchers at the <a href="https://energy.gov/">U.S. Department of Energy's</a> Brookhaven National Laboratory, have taken the first steps toward that conversion by identifying in the lab the metal that can serve as the most efficient catalyst. Metal catalysts interact with metals to speed up chemical reactions that lead to conversions, and the researchers had to test many such metals.

“We found that copper zinc oxide should give the best results, and that copper zinc is not even stable under reaction conditions,” said Dr. Ping Liu, a chemist and the study’s lead author. “In fact, it reacts with oxygen and transforms to copper zinc oxide.”

The next step is to increase efficiencies in the operation.

“We want to improve it, and get it to operate at lower temperatures and lower pressures, which would save energy,” said Liu.

These findings, which were published in Science, could one day lead to technologies for turning a compound that’s slowly poisoning the earth into a useful substance.

Our planet contains countless breathtaking and unforgettable places to explore. This is not among them. Yes, it’s true. You can book a trip to Chernobyl. No, not to the actual reactor. That would be crazy. But you can explore just about everything short of the Chernobyl Sarcophagus, which is about as ominous as it sounds. That’s the massive steel and concrete structure that “temporarily” encases the damaged reactor while a more permanent confinement shelter is in the works.

As for Pripyat and the rest of what’s called the Chernobyl Exclusion Zone or the Zone of Alienation, well, it’s not so alienating anymore. The website for <a href="https://www.chernobyl-tour.com/english/">Chernobyl Tour</a> sums it up best, though in a bit of an understatement: “Radiation makes the zone particularly interesting.”

Not that you and the family have a thing to worry about, Chernobyl Tour assures. Stay for a day or two and…no problem. The tour group promise couldn’t be more reassuring: “Of course, the Zone in its central part still has places with elevated radiation, and we definitely would NOT recommend you staying at them for a long time. However, if you follow the suggested route and the guides' directions, your visit to the Chernobyl zone will be absolutely radiation-safe.”

This, of course, is despite the website’s stated theme for the tour: “Eye-opening experience of post-Apocalyptic world.” 

Indeed. 

But let’s step back for a moment for a brief history lesson.

Meltdown

On the evening of April 26, 1986, Chernobyl, a Soviet-style nuclear power plant, experienced the world’s first Level 7 meltdown of a nuclear reactor. The second such nuclear catastrophe occurred to the <a href="https://www.earth.com/news/scientists-fukushima-radiation-no-threat/">Fukushima</a> Daiichi plant in Japan in 2011, as the result of a devastating earthquake and tsunami.

The Chernobyl plant was – and is – located less than two miles from Pripyat, which was, at the time a thriving city of nearly 50,000 people. Two workers were killed immediately and nearly 30 other firefighters and workers lost their lives to radiation exposure in the days and months that followed. Not that the world learned of this cataclysmic event as it happened. Ukraine was part of the Soviet Union at the time, and authorities tried to keep it quiet. They sealed the damaged reactor in its sarcophagus and evacuated the surrounding cities and villages. 

Ghost town tours

Ukrainian authorities insist that, after 30 years of evacuation, the radiation levels are low enough that tourists can explore the two towns, settlements and villages that comprise the Zone of Alienation. You can see tens of thousands of abandoned homes and other structures, and more than 10,000 tourists a year take up the offer. The once bustling Pripyat is the largest of the ghost towns, and a popular destination for apocalyptical-minded sightseers – especially the abandoned amusement park with its landmark Ferris wheel. 

The Chernobyl Tour is a property of Ukraine’s Ministry of Economic Development and Trade, so it’s fully endorsed by the nation. There are significant explanations of health issues on the website, and an insistence that the stay of even a day or two is safe. In fact, some 200 people, including children, live in the Zone illegally. <a href="https://www.vice.com/en_us/article/hanging-out-with-the-only-residents-of-chernobyls-exclusion-zone">This 2012 Vice article</a> explains that many of those children are seriously ill. 

The photographers and extreme-sport version of tourists who visit can tell their friends they survived Chernobyl. What remains to be seen is whether they can still make that claim in 20 or 30 years.

The after-effects of an earthquake observed through seismic readings are not necessarily the same as when observed by orbiting satellites. That’s one conclusion that can be drawn from the study of the 7.8 magnitude quake that shook up <a href="https://www.earth.com/image/the-south-island-new-zealand/">South Island</a> in New Zealand last November. The event, known as the Kaikoura Earthquake – for the town near the epicenter – is now one of the most-studied quakes in history.

The researchers found that before-and-after photos of the area shot from the satellites Copernicus Sentinel-1 and the Japanese-owned ALOS-2 revealed rupture details previously unknown. The team of scientists from New Zealand, the United States and the United Kingdom started to study the satellite images soon after the quake struck and their findings have been written up in the latest issue of <a href="http://science.sciencemag.org/">Science</a>.

Kaikoura was a major quake, resulting in landslides and a tsunami.

Satellite views showed ruptures and land displacements as much as 30 feet high, and the locations of multiple fault lines. The scientists said that the rupture pattern also gave clues to the formation of nearby mountain ranges.

“An earthquake commonly ruptures across a single fault line or faults that are closely grouped, but Kaikoura ruptured at least 12 major crustal faults across two distinct active fault domains,” said Professor Tim Wright, study co-author and director of the Centre for the Observation and Modelling of Earthquakes, Volcanoes and Tectonics at the <a href="https://www.leeds.ac.uk/">University of Leeds</a> in the UK. “This challenges many assumptions about how individual faults control earthquake ruptures.”

The scientists said that their study of the Kaikoura quake could help seismologists reevaluate seismic hazard models.

“The message from Kaikoura is that earthquake science should be more open to a wider range of possibilities when rupture models are being developed,” said Dr. Ian Hamling, a natural hazards geodesist from GNS Science and the lead author of the just-released study. “It underlines the importance of re-evaluating how rupture scenarios are defined for seismic hazard models.”

Coral <a href="https://www.earth.com/image/grand-turk-island-coral-reefs/">reefs</a> are among the most delicate and unique ecosystems on our planet, containing a wide variety of marine life that rely on the reefs for food and protection. However, these days our reefs are under more destructive threats than ever before.

A new study has found that some coral reefs could be experiencing even more damage from invading bacteria and fungi, which may migrate from land-based sources. Outfall from sewage treatment plants and coastal inlets could be the culprit in many cases.

The research, published in <a href="http://aem.asm.org/">Applied and Environmental Microbiology</a>, points specifically at the reefs off the southeastern coast of Florida. Researchers Chan Lan Chun and Michael Sadowsky – both of the <a href="http://www.d.umn.edu/">University of Minnesota, Duluth</a> – took water samples from coastal inlets and oceanic outfall effluent that came from water treatment plants along Florida’s southeastern coast. They also retrieved water samples and samples of coral tissues in the reefs.

They found a crossover between specific bacterial species as well as fungal families in both land-based sources and in the water and tissues of the reefs. Along the coastline the scientists studied, the distance from sewage outfall pipes to the reefs ranged from 5.5 to 25 miles.

Sadowsky explained their hypothesis, saying “The [data] we have now strongly suggests that anthropogenic input sources are becoming established on reefs.” Anthropogenic means originating from human activity, so the researchers clearly believe these invasive microbes are a direct result of the nearby sewage runoff. However, more experiments would need to be done to support this hypothesis.

In the meantime, the researchers are worried these microbes will be damaging to nutrient cycling and coral health within the reef. Invaders such as these could easily disrupt the balance of the flora and fauna in this delicate ecosystem. 

It remains to be seen if invading microbes will be yet another source of destruction to take down coral reefs. With climate change and coral bleaching already destroying reefs around the world, these ocean ecosystems need our help now more than ever.

The <a href="https://www.earth.com/news/idea-tackle-arctic-ice-melt/">Arctic</a> just set another new record – and it’s not one that pleases climatologists. For the third straight year, the polar region saw a reduction in the amount of sea ice at the end of winter, according to satellite data released by the <a href="https://nsidc.org/">National Snow and Ice Data Center</a>.

It was the lowest amount of sea ice ever found in nearly 40 years of measurements by satellite. And much of the ice that did survive the winter appeared to be thinner than usual, due to dramatically high temperatures recorded at the North Pole.

“This is just another exclamation point on the overall loss of Arctic sea ice coverage that we’ve been seeing,” Mark Serreze, the data center’s director, told the <a href="http://www.nytimes.com/">New York Times</a>.

What this is leading to is a polar region that will see no ice coverage at all during the region’s summer months, an annual occurrence that could happen as early as the next couple decades.

While the sea ice loss doesn’t trigger rising seas, it does unbalance the region’s food chain by, for instance, delaying the bloom of phytoplankton at the bottom of the chain. Less sea ice also means there’s more open ocean to absorb the sun’s energy, which leads to additional warming globally.

To understand the scale of the seasonal ice loss, consider that the iced-in sea area recorded this winter in the Arctic is some 470,000 square miles less that the average annual figure from the years 1981 to 2010.

It’s no wonder. Recorded temperatures late last fall were, in some parts of the Arctic, as much as 35 degrees Fahrenheit higher than the usual recorded temperatures for that time of the year. Even right at the North Pole, mean temperatures late last year were 23 degrees warmer than normal.

Can <a href="https://www.earth.com/news/south-georgias-past-ice-cap/">climate change</a> be a beautiful thing? At least it can sometimes seem that way. When observed at a very micro level, some of the damage created by our irresponsible environmental stewardship can look misleadingly attractive. 

Monet’s waterlilies 

The French impressionist Claude Monet wrote, “I am only good at two things: gardening and painting.” He combined his two talents by spending the last 30 years of his life mainly painting the waterlilies in his beloved garden – a portfolio of some 250 of his most classic works. 

Monet’s waterlilies would be in colorful abundance if he were alive today. That, unfortunately, is at least in part because the greenhouse effect, brought on by the release of carbon dioxide into the atmosphere. The effect warms the planet – and waterlilies love the warmth. They also thrive in shallow water, and that’s an environmental fact in many regions of the world.  

As UN-Water, the United Nations agency on water issues, wrote, “Higher temperatures and changes in extreme weather conditions are projected to affect availability and distribution of rainfall, snowmelt, river flows and groundwater, and further deteriorate water quality.”

Not that all waterlilies are thriving these days. Tropical lilies In the Na Kha river basin in Thailand are threatened with extinction due to the damage done by water pollution.

The emerald green sea

The description of a vast emerald green body of water sounds inviting. Except that this particular photo op portends a winter dead zone in the Arabian Sea about the size of Texas – and still growing. The water’s soothing coloration is due to the winter and summer bloom of Noctiluca scintillans, more commonly known as sea sparkle. These microscopic bioluminescent plankton glow because of the chlorophyll in them. And their widespread presence here is because they – and they alone – thrive in the dying waters. 

The Arabian Sea has this ever-growing patch of oxygen-depleted water because of the overpowering amount of raw sewage and fertilizer that finds its way into the sea. Man’s devastation throws off the whole food chain, resulting in the loss of the fishing that sustains life in the region – and a beautiful, serene sea of emerald green. 

A haunting blue luminescence 

Noctiluca scintillans strikes again. Only this time the plankton’s base is at Preservation Bay, along the southern coast of Australia. CBS News described the sea sparkle bloom, just a few days ago, as “an ethereal blue light riding the waves along a beach in Tasmania.”

As poetic as it sounds – and the sight is attracting tourists and photographers – this plankton outburst once again signifies troubled waters. Different outbreaks of the sea sparkle have bloomed in green, such as in the Arabian Sea, or in red, as occurred at Bondi Beach in Sydney, Australia in 2012.

Regardless of the attractive coloration of the plankton, and of the gracious waterlilies, this activity taps into the damage human beings are causing our environment in a variety of ways. It’s a potentially deadly beauty, and one that only a photographer or landscape artist could truly appreciate.

Earth.com Feature: When environmental damage creates beauty

Can climate change be a beautiful thing? At least it...

Upon reacting to the release of the annual report of the World Meteorological Organization, Dr. Phil Williamson, associate fellow at the <a href="https://www.uea.ac.uk/">University of East Anglia</a> in England had some harsh words for climate change doubters in an interview with the <a href="http://www.dailymail.co.uk/ushome/index.html">Daily Mail</a>. He was addressing the release of the annual report from the <a href="https://www.wmo.int/">World Meteorological Organization</a>, a specialized agency of the <a href="http://www.un.org/en/">United Nations</a>.

“Human-driven climate change is now an empirically-verifiable fact,” he said. “Those who dispute that link are not sceptics, but anti-science deniers.”

The <a href="https://www.wmo.int/">WMO</a> report released earlier this week stated that, once again, last year was the warmest since measurements had been made in 1880.

 Other “lowlights” of the report were that <a href="https://www.earth.com/news/rising-sea-louisiana-coast/">sea levels</a> continued to rise due to melting polar ice and Arctic and Antarctic ice levels were far below average.

“With levels of carbon dioxide in the atmosphere consistently breaking new records, the influence of human activities on the climate system has become more and more evident,” WMO chief Petteri Taalas wrote.

The report shows that the effect of greenhouse gases can be felt in a number of ways. For instance, warming in the Arctic and melting sea ice were leading to a shift in wider oceanic and atmospheric circulation patterns. That, in turn, created confusing weather conditions all over the globe, and including unexpected highs in the U.S. and Canada last year and chilly temperatures in the Arabian peninsula and North Africa.

Worst of all, the WMO report indicated that we’re making few gains in defense of the planet.

“Provisional data also indicates that there has been no easing in the rate of increase in atmospheric carbon dioxide concentrations,” it stated.

The phenomenon is suspected to be brought about by some of the hottest summers on record, due to climate change. As the soil warms, it thaws pockets of methane gas that had been frozen beneath the surface for thousands of years.

Satellite imagery has revealed the craters and funnels caused by numerous of these explosions, and scientists describe walking on ground that feels spongy with gas built-up.

Alexey Titovsky, director of one of the affected region’s department for science and innovation, said that the methane gas bubbles are contained in what are known locally as pingos, the dome-shaped mounds of soil encasing large segments of ice.

“At first such a bump is a bubble,' he said. “With time the bubble explodes, releasing gas. This is how gigantic funnels form.”

The craters and funnel-shaped gouges in the earth can be seen by satellite. Fortunately, the region is not well populated, so there’s little risk to humans. In fact, one of the Arctic peninsulas is known by the natives as “the end of the world.” However, the explosions could affect energy production facilities in the area – and they serve as yet one more alarming evidence of climate change.

According to an article published yesterday in the <a href="http://www.nytimes.com/">New York Times</a>, the Trump administration is about to start the process of rolling back former President Barack Obama’s set of environmental regulations knowns as the Clean Power Plan – but it won’t be easy. It will be a long and arduous process, and one fraught with lawsuits that will probably end up before the U.S. Supreme Court in years to come. In the meantime, however, there are smaller steps the president is taking to change Obama-era policies, rules and regulations.

The Clean Power Plan is a set of regulations that, in part, shut down hundreds of high-polluting coal-fired power plants and froze the construction of new plants. Trump signaled that he was about to challenge those regulations when he told a Kentucky audience earlier in the week that he was preparing a plan to “save our wonderful coal miners from continuing to be put out of work.”

Most economists have concluded that the coal mining industry was on life support even before the election and that most of the lost jobs won’t be coming back because energy technology has moved beyond <a href="https://www.earth.com/news/obama-protect-streams-forests-coal-mining/">coal</a>.

Despite the long road ahead of the Trump administration in killing the Clean Power Plan, the president has also taken several quicker steps to weaken or roll back Obama-era initiatives to address climate change by:
<ul>
 	<li>    Proposing to reduce the budget of the Environmental Protection Agency by 31 percent, the steepest cut    to any federal agency, and eliminate funding for climate change research</li>
 	<li>    Lifting the former president’s moratorium on new coal mining leases on public lands</li>
 	<li>    Announcing last week that he’d ordered EPA Administrator Scott Pruitt to revise the agency’s standards on vehicle tailpipe pollution</li>
</ul>
The administration is also expected to eliminate an Obama budgeting metric that assigned a carbon a social cost of $36 per ton when issuing regulations that could hurt industries such as coal mining, and rescind an executive order by Obama mandating that federal agencies take climate control into consideration when issuing environmental permits.

In addition, <a href="https://www.epa.gov/">EPA</a> Administrator Scott Pruitt butted heads with most climate scientists in announcing earlier this month that he didn’t believe carbon dioxide was the main driver of climate change. And Trump’s budget director, Mick Mulvaney, said in regards to budget cuts to environmental agencies and programs, “As to climate change, I think the president was fairly straightforward. We’re not spending money on that anymore.”

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

Today’s Video of the Day from 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."

Today’s Video of the Day from <a href="http://www.ntu.edu.sg/">NTU Singapore</a> reveals that some plants can remove toxic heavy metals from soil.&nbsp;



The researchers analyzed samples of various tropical plant species to test for levels of heavy metals and metalloids. The study showed that there are existing plants with high levels of these contaminants, which means that these species are great candidates for drawing pollutants out of the soil.&nbsp;



Among the plants examined in the study, 12 species had accumulated several types of heavy metals and metalloids. These plants are widely available, including species that are native to Singapore.



“In a small nation like Singapore, land may be repurposed to support new development plans, so it is important that we have a green and sustainable way to remediate land that is contaminated," said Professor Lam Yeng Ming.



"We set out to uncover how to better make use of tropical plants to do phytoremediation and through advanced characterization techniques, we showed how some of these tropical plant species can be an environmentally friendly and literally a 'green' way to remove contaminants in soil."&nbsp;



"Phytoremediation also has benefits of cost effectiveness, simplicity of management, aesthetic advantages, and long-term applicability and sustainability. The strategy prevents erosion and metal leaching by stabilizing or accumulating heavy metals, so that helps reduce the risk of contaminant spread.”

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes why herbicides are not as effective in killing weeds anymore. In the 20th century, chemical companies developed thousands of herbicides. The most commonly used herbicide was glyphosate, which was introduced in 1974.



Over the past few decades, dozens of species of weeds have evolved resistance to glyphosate. Depending on the site of action, the part of the plant that an herbicide interacts with, weeds may even be resistant to herbicides that have not been developed yet.&nbsp;



With increasing resistance to glyphosate and other herbicides, weeds are - once again - becoming a major concern for farmers.&nbsp;

Today’s Video of the Day from the <a href="https://www.jpl.nasa.gov/">NASA Jet Propulsion Laboratory</a> (JPL) describes a dust storm on Mars that was nearly twice the size of the United States. As the storm covered the southern hemisphere of the planet, some of NASA’s explorers had to delay their normal activities.



NASA’s Insight lander put itself in a "safe mode" for 11 days to conserve battery power because solar power was disrupted by the dust. The Ingenuity Mars Helicopter postponed flights until conditions improved.



"A fleet of NASA orbiters monitor Martian dust storms like this one and serve as lifelines to Earth by relaying data from the rovers and lander on the ground back to the team. This includes the Mars Reconnaissance Orbiter, MAVEN, and Odyssey," reports JPL.



"Dust storms like this recent one start close to the ground and are spread by wind as they rise – warming the cold Martian atmosphere."



The images in the video were captured by NASA’s Curiosity as the dust rolled in. A fleet of orbiters monitored the dust storm from above, relaying data from Mars’ explorers back to scientists on Earth.

Qeshm is separated from the Iranian coast by the Clarence Strait, also known as Khuran.&nbsp;The Hara Forest Protected Area is a network of shallow waterways and forest located between the island and the mainland. This protected region is home to sea turtles, snakes, and more than 150 species of migrating birds.



Qeshm is famous for its wide range of&nbsp;ecotourist&nbsp;attractions, such as the&nbsp;Hara marine forests. According to environmentalists, about 1.5 percent of the world birds and 25 percent of Iran's native <a href="https://www.earth.com/news/female-hummingbirds-avoid-sexual-harassment-by-looking-like-males/">birds</a> annually migrate to the forests, which are the first national geo park in Iran.



Tourists are also drawn to the island to see an age-old Portuguese&nbsp;fort, historic mosques, the&nbsp;Seyyed Mozaffar&nbsp;and&nbsp;Bibi Maryam&nbsp;shrines, and the "Valley of Stars."



The average temperature on the island is 81 degress and the region is often hot and humid. From June to August, the island is described as being oppressively hot. The ideal time to visit is during the winter season.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Inhambane Bay in southeast Mozambique.&nbsp;



"Inhambane Bay is a deep inlet into which the small Mutamba River flows," says ESA. "On one side of the bay lies the historical city of Inhambane, capital of the Inhambane Province, while the sister city of Maxixe, the economic capital of Inhambane, sits across from it. The province is the second largest grower of cashews, after Nampula, and it also produces coconut and citrus fruits."



The beaches of Barra and Tofo are popular with tourists. There are also coral reefs along the long coastline of Inhambane, making it an ideal destination for scuba diving and snorkeling.



"Mozambique’s extensive coastline heightens the country’s vulnerability to tropical cyclones that develop in the Indian Ocean as well as storm surge flooding," says ESA.



"More than half of the population lives in low lying coastal areas, putting communities at risk. Inhambane Bay was dangerously close to where Cyclone Idai made landfall in 2019 causing widespread destruction to the country."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency </a>&nbsp;features the Kangerlussuaq Glacier, one of the largest tidewater outlet glaciers in Greenland. The glacier is located on the east coast of the Greenland ice sheet.



As human-induced climate change continues to drive up temperatures, global ice loss is accelerating at an alarming rate. ESA reports that, over the past decade alone, 3.5 trillion tons of ice have melted from the Greenland ice sheet. This is enough to cover the UK with meltwater 15 meters deep.



Based on satellite imagery, researchers determined that Kangerlussuaq entered a new phase of rapid retreat and acceleration in 2017. In their study, published in <a href="https://www.frontiersin.org/articles/10.3389/feart.2019.00123/full">Frontiers in Earth Science</a>,&nbsp; the experts report that the glacier's ice front is now at its most retreated position since the early 20th century.



"Given Kangerlussuaq’s previous impacts on both the magnitude and pattern of ice sheet wide mass loss, we predict that its new phase of retreat, acceleration and thinning will markedly enhance the south-east region’s contribution to increasing discharge from the ice sheet," wrote the study authors.&nbsp;&nbsp;



"More broadly, accurate forecasting of the ice sheet’s contribution to sea level rise will require a deeper understanding of, and responses to, these non-linear ice dynamic processes."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the complex relationship between ocean and climate. ESA's Climate Change Initiative will help us understand how oceans influence the climate and how climate change is impacting the oceans.&nbsp;



"Earth’s oceans are huge heat stores, soaking up 93% of the excess heat from human activity over the past 70 years. Ocean currents redistribute heat around the planet, from the Equator to the poles. Where this ocean heat goes influences weather patterns and regional climate," explains ESA.



"As well as absorbing heat, oceans are a natural carbon sink, absorbing a quarter of carbon dioxide emissions from human activity. This has led to the acidification of ocean water, threating marine life."



The amount of heat and carbon dioxide soaked up by the ocean depends on specific variables, including phytoplankton, temperatures, waves, salinity, and ice cover. Satellites can be used to measure these variables from space.



"From their unique vantage point, satellites provide key information for understanding the complexities of our planet and monitoring environmental issues," says ESA.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the importance of monitoring the shape of the sea surface, which is constantly changing. These observations have many applications, such as ship routing, <a href="https://www.earth.com/news/the-modem-ocean-is-a-tough-place-for-whales-to-survive/">ocean</a> current forecasting, and debris tracking.



"A project supported by the Discovery element of ESA’s Basic Activities recently investigated a new technique to measure sea surface topography very precisely," reports ESA.



"The technique involves looking at satellite navigation (GNSS) signals that have been reflected off of the sea surface at very low angles. At these so-called grazing angles, waves and surface roughness have very little impact on the reflection process; the sea surface acts as a very smooth mirror."



Estel Cardellach is the principal investigator at the Institute for Space Studies of Catalonia, who first submitted the idea for the project.



“In a mirror-like reflection the phase of the signal can be tracked – it is continuous," said Cardellach. "Different surface heights result in different phase measurements. It gives a very precise measurement of the surface altitude at a few centimetres’ precision.”



The researchers developed a GNSS receiver and set up an experiment in the Balaeric Islands to collect signals from the receiver that were reflected off the sea surface. Ultimately, these signals will provide improved measurements of the shape of the sea surface.

Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA’s Goddard Space Flight Center</a> describes how scientists are using autonomous sound sensors to monitor deforestation in the Amazon. By recording soundscapes, the experts can determine which animals are present through their distinct sounds.&nbsp;



Using this method, sounds can be used as scientific measurements to analyze the effects of deforestation. The researchers will gain a better understanding of how the acoustics of a forest can be used to measure its health.&nbsp;



"From space, parts of the Amazon rainforest that have previously been logged or burned may look lush and green, like a place buzzing with activity and full of sounds. But inside the rainforest, the animal life may tell a different story, of a harsh environment and a quieter soundscape," says NASA.
