A new study has found that, contrary to previous claims, the ocean is not a significant source of microplastics to the atmosphere, but rather a major sink.&nbsp;



The research team used a global chemical transport model to evaluate how tiny plastic particles, known as microplastics, move around the world. 



The finding challenges past assumptions about the ocean’s role in releasing plastic fragments into the air.



<h2 class="wp-block-heading" id="h-the-journey-of-airborne-microplastics-nbsp">The journey of airborne microplastics&nbsp;</h2>



Plastic debris in dust form is increasingly recognized as a worldwide contaminant. <a href="https://www.earth.com/news/microplastics-in-the-brain-alarming-new-details-revealed/" target="_blank" rel="noreferrer noopener">Microplastics</a> (particles less than 5 mm in diameter) have been detected in soils, freshwater, the ocean, and even in the air that we breathe.&nbsp;



Scientists warn that microscopic plastic bits pose risks for human health, since they can easily enter the respiratory system and the bloodstream.&nbsp;



Once airborne, these tiny pieces can travel large distances and eventually settle in remote or sensitive regions, harming wildlife and potentially impacting human populations.



But how do these particles enter the atmosphere in the first place? The planet’s primary sources of microplastics are typically found on land, from everyday materials such as vehicle tires shedding particles on roads, or synthetic clothing fibers washed out in domestic wastewater.&nbsp;



However, earlier models had suggested that there might be an additional large source at sea. Microplastics often accumulate in the <a href="https://www.earth.com/news/microplastics-pose-a-greater-threat-to-some-ocean-animals/" target="_blank" rel="noreferrer noopener">oceans</a>, carried there by rivers and other waterways. Then, once present in the marine environment, it was believed that they could be lofted into the air by sea spray or wind-driven wave action.



<h2 class="wp-block-heading" id="h-what-is-the-ocean-s-contribution">What is the ocean's contribution?</h2>



Prior reports pointing to a large marine source relied on an inverse modeling technique. That method uses atmospheric measurements of particular substances and attempts to infer their origin by matching observed concentrations with predicted distributions.&nbsp;



Applied to microplastics, inverse modeling suggested the ocean might contribute hundreds of millions - or even billions - of kilograms of these fragments to the air each year.



Such massive figures were then tested experimentally, with scientists using wave tanks and other controlled setups to see how vigorously wave action or bursting bubbles could transfer plastics from the water surface into the atmosphere.&nbsp;



Those studies, however, hinted that only tens or hundreds of thousands of kilograms of plastic might plausibly be introduced into the air - orders of magnitude smaller than the figures derived from inverse modeling.



<h2 class="wp-block-heading" id="h-a-global-chemical-transport-model">A global chemical transport model</h2>



In an effort to reconcile these contradictory outcomes, a group led by researchers at the <a href="https://mpimet.mpg.de/en/homepage" target="_blank" rel="noreferrer noopener">Max Planck Institute for Meteorology</a> (MPI-M) ran a global chemical transport model. This computer model simulates the movement of substances, such as microplastic particles, through the atmosphere.&nbsp;



By prescribing a minor oceanic emission of microplastics - consistent with the low estimates from laboratory work - they were able to predict how microplastic concentrations should appear in the air at various locations around the globe.



The results aligned well with real-world measurements. Based on the model, the ocean in fact took up some of these airborne particles instead of emitting them in large quantities.&nbsp;



The scientists learned that rather than being a source, the ocean appeared to be a sink, in which 15 percent of all airborne microplastics are deposited.&nbsp;



In other words, waves, spray, and wind may occasionally lift small amounts of plastic out of the sea, but far more of the material is settling onto the water rather than emanating from it.



<h2 class="wp-block-heading" id="h-how-airborne-microplastics-travel">How airborne microplastics travel</h2>



The study also uncovered the significant influence of particle size on how microplastics travel. Larger plastic fragments drop out of the atmosphere relatively quickly, often landing in coastal areas or not far from their point of emission.&nbsp;



By contrast, smaller particles can remain suspended for up to a year. That extended flight time allows them to cross entire oceans or continents and reach distant regions such as the <a href="https://www.earth.com/news/citizen-scientists-uncover-microplastics-in-the-remote-arctic/" target="_blank" rel="noreferrer noopener">Arctic</a>, where they land on ice or snow.



These discoveries highlight the global character of plastic contamination, showing that microplastic dust can be widespread in places typically considered pristine.&nbsp;



They also clarify that stopping microplastic pollution at its land-based sources may be the most efficient approach, as the ocean itself is neither the greatest emitter nor the root cause.



<h2 class="wp-block-heading" id="h-a-roadmap-for-pollution-reduction">A roadmap for pollution reduction</h2>



Given that airborne microplastics reach faraway corners of the planet, the research team’s results have immediate practical value. Any broad plan to cut plastic pollution should focus on terrestrial origins: tire wear on roads, textiles shedding fibers, and insufficiently treated wastewater.&nbsp;



Additionally, lessening single-use plastics and improving waste management at landfills can help limit microplastics before they disperse into the environment.



These findings show that ocean waters, already burdened by plastic accumulations, are predominantly sinks - taking in plastic particles from the air. They also emphasize that microplastics do not stay put in the environment: large ones settle nearby, while smaller ones can travel global distances.&nbsp;



Future models aimed at <a href="https://www.earth.com/news/plastic-pollution-is-changing-the-entire-earth-system/" target="_blank" rel="noreferrer noopener">plastic pollution</a> will need to consider these dynamics in more detail, particularly when mapping out strategies to protect vulnerable ecosystems, reduce human exposure, and maintain cleaner oceans.



By settling this debate over whether the ocean is more of a source or a sink, scientists can now direct their attention to mitigating the true origins of airborne microplastics, thus improving targeted policies to help address this pressing environmental concern.

BP Oil Spill Settlement Money Found In Strange Places. Clusters of landlocked municipalities more than 100 miles from the Gulf Coast have secured millions of dollars in BP money through settlements designed to compensate local governments for lost tourism dollars and other economic damage from the company's 2010 oil spill, according to records obtained by The Associated Press.
This week, BP finished making approximately $687.4 million in settlement payments to 383 local government entities in the five Gulf states. Nearly $8 million of that money went to 32 government entities that are more than 100 miles from the coast, in places like the<a href="https://www.bing.com/search?q=mississippi&amp;cvid=a6dd128c0c76464cb2b2849ff061a493&amp;FORM=ANAB01&amp;PC=HCTS"> Mississippi</a> Delta and suburbs of central Alabama, the records show.BP Oil Spill Settlement Money Found In Strange Places
BP's well blowout off Louisiana's coast triggered a deadly explosion that killed 11 rig workers and spewed millions of gallons of oil into the Gulf of Mexico, staining beaches, killing wildlife and scaring away tourists.
The company agreed last month to pay up to $1 billion to resolve economic claims by local governments, but the settlement payouts have fallen well short of that maximum amount. The records obtained by the AP provide the most comprehensive accounting of where the money went and what types of government entities received shares.
The AP analyzed minimum distances from the center point of each city or town to the coastline to determine which locations were farther than 100 miles away from the coast.
Jackson, Mississippi, approximately 175 miles from the coast, received $1.3 million. Birmingham, Alabama, more than 200 miles from the coast, received $1 million.
Among the smaller cities receiving money is Ruleville, a Mississippi Delta city that landed $40,748. Ruleville, which is nearly 300 miles from the coast and has about 3,000 residents, said it lost revenue from sales taxes and other sources due to a drop in tourist travel after the spill. The city, perhaps best known as the hometown of civil rights activist Fannie Lou Hamer, is in an area that is a popular destination for blues music fans.
"Everybody in Mississippi suffered to varying degrees," said Danny Griffith, Ruleville's city attorney.
Irondale Mayor Tommy Joe Alexander - whose city in the <a href="http://www.earth.com/news/drinking-cocoa-can-make-your-brain-sharper-and-faster/">Birmingham</a> suburbs received a $57,225 settlement award - said a seafood shortage after BP's spill led to a decrease in sales tax generated by local restaurants.
"We're very fortunate that we did get something," he said. "There was an impact on the whole state."
BP's settlements with local governments are part of its broader $18.7 billion agreement with the five Gulf Coast states and the federal government. Larger portions of settlement money are dedicated to coastal restoration work. BP already has paid billions of dollars in compensation to Gulf Coast businesses and residents who claim the spill cost them money.
July 15 was the deadline for local governments to decide whether to accept the settlement offer, which could not be renegotiated. BP, which couldn't veto individual payments, accepted the package of settlements on July 27.
A modest "windfall" for several communities far from the coast must have been an afterthought for BP given the broader deal's high stakes, according to Ed Sherman, a Tulane University Law School professor emeritus and expert in complex litigation.
"It's not a great deal of money when you consider the total amount of the settlement," Sherman said.
Only a handful of local governments have publicly announced that they rejected a settlement offer. They are free to continue pursuing their claims, but may have to wait for a trial date if BP is unwilling to negotiate a separate deal.
Many local governments that sued BP over the spill enlisted help from private attorneys who handled their claims on a contingency basis, typically in exchange for at least 20 percent of the settlement amount.
Ike Gulas, an attorney who filed claims for several government entities in the Birmingham area, said officials from other local communities contacted him after the settlement was announced last month and were disappointed to learn it was too late to file their own claims.
"A lot of lawyers looked at it and didn't think there was a claim there, but we did," Gulas said.
Many communities sought significantly more than what they ultimately accepted. Bessemer, another Birmingham suburb, accepted a $310,392 settlement, even though city attorney Shan Paden said independent accountants pegged Bessemer's spill-related losses at roughly $590,000.
"The timing was bad," Paden said of the spill. "The general economy was in bad shape. We can show objectively that the revenues were down for that period of time."
The federal judge overseeing most of the spill-related litigation against BP appointed a panel of neutral parties, including former FBI director Louis Freeh and Lafayette-based attorney Patrick Juneau, to determine the amounts of each settlement offer. The formulas and criteria used by the panel members have not been publicly disclosed.
The panel made offers to each local government that met certain legal requirements. To qualify, each government entity had to formally present its Oil Pollution Act claim to BP and either file a lawsuit or submit a two-page claim form directly to the federal court in New Orleans.
The $687.4 million in payments doesn't include awards to local governments that resolved their BP claims before the broader settlement was announced on July 2.
Nearly $371 million - more than half of the total settlement money - was awarded to local governments in Louisiana. Approximately $210 million is going to local governments in Florida, where the tourism industry cratered in the spill's aftermath even though few places in the state ever felt any direct impact from BP's oil. Local governments in Texas are getting $39.9 million, while those in Mississippi are receiving $37.3 million. Local governments in Alabama are getting $28.8 million.
The bulk of the settlement money - which was paid by BP in lump sums and can be spent on anything - is going to city and county or parish governments along the coast. Nearly $157 million, almost one quarter of the total, is going to more than 50 public school districts. Law-enforcement agencies are receiving around $21 million. Airports are getting nearly $15 million. About $6 million is going to hospitals.
William Husfelt, schools superintendent in Bay County, Florida, said the spill led to losses in property and sales tax revenues that fund public schools across the state.
"It was a terrible time for it to happen. It was right after the recession," he said. "The budgets were cut. Pay raises were flat."
Henry Kelley, a spokesman for the Okaloosa County, Florida, public schools, said the school board hadn't yet decided how to use its $2 million settlement award.
"We're not flush with cash. If spent properly, this will make a big impact," he said.

This story has been corrected to indicate that 32 recipients, not 33, are more than 100 miles away from the coast, and that the amount of money going to those entities is nearly $8 million instead of nearly $8.2 million.

BP Oil Spill Settlement Money Found In Strange Places

Western Wildfires Burning Unchecked Due To Lack Of Firefighters. This summer's massive western wildfires have strained resources to the point that<a href="https://www.bing.com/search?q=wildfire&amp;cvid=3d1e2b511a104aeaa6d8b0656bf735b0&amp;FORM=ANAB01&amp;PC=HCTS"> wildfire</a> managers are being forced to let some fires burn unchecked, and that has renewed a longstanding debate about whether it is better to fight a fire - or to sometimes just let it burn out.
Drought and heat have combined to make this one of the most active fire seasons in the Lower 48 in recent years. Nearly 29,000 firefighters are battling some 100 large blazes across the West, but it hasn't been enough. In northern Idaho, private citizens have even jumped on fire lines to help overwhelmed firefighters. Western Wildfires Burning Unchecked Due To Lack Of Firefighters
"What we're getting now are much more intense fires because of all those years of suppression," said John Freemuth, a Boise State University professor and a public lands expert. "Those kinds of intense fires are usually not allowed to burn."
But fire managers have little choice this year.
Some 11,000 square miles have burned so far. Most of that has been in Alaska, but an increase in fires in the Idaho, Oregon, Montana, Washington and California has caused competition for firefighting resources with some requests going unmet.
Some fires have simply been unstoppable. Steve Ellis, deputy director of the U.S. Bureau of Land Management, earlier this week flew over a 443-square-mile rangeland fire in southwest Idaho and said he could see where retardant bombers put in lines that the fire easily crossed.
"It's always tough when we get to this point where we have much more fire than we have resources," said John Segar, one of eight members on an interagency group based in Boise that decides how to deploy the nation's wildland firefighters. "The decisions are essentially triage decisions."
Segar, chief of Fire Management for the U.S. Fish and Wildlife Service, sits on the National Multi-Agency Coordination Group at the National Interagency Fire Center.
While there's been a longstanding debate about whether it's better to fight a fire or just let it burn out, Sager said conditions are so volatile right now that every current fire or new fire start is being attacked with the intent of putting it out if resources are available.
"It's just been too dry and too hot," he said. Letting fires burn "really hasn't been a consideration this year."
Freemuth said land managers have moved toward recognizing using fire as a tool to reduce fuels that lead to intense fires, particularly after the giant fires in Yellowstone National Park in the late 1980s.
"Having fire on the landscape in the right conditions has been accepted management now," Freemuth said.
But efforts to reduce the threat of fires have been hampered by a lack of money for prescribed burns or work to clear brush.
Some Western lawmakers, including Republican Sens. Mike Crapo and Jim Risch of Idaho and Democratic Sen. Ron Wyden of Oregon, have been pushing for letting firefighting agencies use dollars meant for natural disasters. Currently, agencies have been dipping into money set aside for fire prevention, such as prescribed burns.
"It's sort of an East-West issue where other members of Congress and other parts of the country don't get it because they don't see these kinds of fires," Freemuth said.
Even some <a href="http://www.earth.com/news/scientists-track-endangered-green-turtles-in-western-australia/">Western</a> residents don't want to allow beneficial fires to burn because of the smoke, he noted. "It's like two environmental values having to be reconciled - the need for the right kind of fire and the need for good air quality."
Arguments have also been made for decades that more logging to remove trees and grazing by livestock to mow down grasses could remove fuels that would otherwise burn.
"Those can be legitimate tools," Freemuth said. "But that gets to the question of what's the purpose of our federal lands. Other people are going to say the No. 1 purpose should be ecosystem health."
Segar said the fires this year will likely burn until a season-ending weather event with rain or snow arrives, which could be weeks.
"We have so much fire on the ground we don't have enough people to put them out," he said. "They'll go out at the end of the season."

July Was The Hottest Month Ever Recorded On Earth. Earth just keeps getting hotter. July was the planet's hottest month on record, smashing old marks, U.S. weather officials said.
And it's almost a dead certain lock that this year will beat last year as the warmest year on record, they said.
July's average temperature was 61.86 degrees <a href="http://www.earth.com/news/babbler-birds-are-shifting-their-behavior-in-the-wrong-direction/">Fahrenheit</a>, beating the previous global mark set in 1998 and 2010 by about one-seventh of a degree, according to figures released Thursday by the National Oceanic and Atmospheric Administration. That's a large margin for weather records, with previous monthly heat records broken by a 20th of a degree or less.
"It just reaffirms what we already know: that the Earth is warming," said NOAA climate scientist Jake Crouch. "The warming is accelerating and we're really seeing it this year."
NOAA records go back to 1880. Separate calculations by NASA and the Japanese weather agency also found July 2015 to be a record.
The first seven months of 2015 were the hottest January-to-July span on record, according to NOAA. The seven-month average temperature of 58.43 degrees is 1.53 degrees warmer than the 20th-century average and a sixth of a degree warmer than the old record set in 2010.
Given that the temperatures have already been so high already - especially the oceans, which are slow to cool - NOAA climate scientist Jessica Blunden said she is "99 percent certain" that 2015 will be the hottest on record for the globe. The oceans would have to cool dramatically to prevent it, and they are trending warmer, not cooler, she said.
Crouch, Blunden and other scientists outside of the government said these temperatures are caused by a combination of man-made climate change and a strong, near-record El Nino. An El Nino is a warming of the equatorial Pacific Ocean that alters weather worldwide for about a year.
The oceans drove the globe to record levels. Not only were the world's oceans the warmest they've been in July, but they were 1.35 degrees warmer than the 20th-century average.
The heat hit hard in much of Europe and the Middle East. It was the hottest July on record in Austria, where records go back to 1767. Parts of France had temperatures that were on average 7 degrees above normal and temperatures broke 100 in the Netherlands, which is a rarity. And an Iranian city had a heat index (the "feels like" temperature) of 165 degrees, which was still not quite record.
Nine of the 10 hottest months on record have happened since 2005, according to NOAA. Twenty-two of the 25 hottest months on record have occurred after the year 2000. The other three were in 1998 and 1997.
This shows that despite what climate change doubters say, there is no pause in warming since 1998, Blunden said.
It doesn't matter if a month or a year is No. 1 or No. 2 or No. 5 hottest on record, said University of Georgia climate scientist Marshall Shepherd.
"The records are getting attention but I worry the public will grow weary of reports of new records each month," Shepherd said in an email. "I am more concerned about how the Earth is starting to respond to the changes and the implications for my children."

Nine of the 10 hottest months on record have happened since 2005, according to NOAA. Twenty-two of the 25 hottest months on record have occurred after the year 2000. The other three were in 1998 and 1997.
This shows that despite what climate change doubters say, there is no pause in warming since 1998, Blunden said.
It doesn't matter if a month or a year is No. 1 or No. 2 or No. 5 hottest on record, said University of Georgia climate scientist Marshall Shepherd.
"The records are getting attention but I worry the public will grow weary of reports of new records each month," Shepherd said in an email. "I am more concerned about how the Earth is starting to respond to the changes and the implications for my children."

Earth just keeps getting hotter. July was the planet's hottest month...

1,800 Years Of Global Ocean Cooling Halted By Global Warming. Comprehensive analysis of ocean surface temperature data shows a cooling trend preceding the Industrial Revolution

Prior to the advent of human-caused global warming in the 19th century, the surface layer of Earth’s oceans had undergone 1,800 years of a steady cooling trend, according to a new study. During the latter half of this global ocean cooling period, the trend was most likely driven by large and frequent volcanic eruptions.1,800 Years Of Global Ocean Cooling Halted By Global Warming

An international team of researchers reported these findings in the August 17, 2015 issue of the journal Nature Geoscience. The study also indicates that the coolest temperatures occurred during the Little Ice Age—a period that spanned the 16th through 18th centuries and was known for cooler average temperatures over land.

The concurrence of cooling events on both land and sea suggests that a <a href="http://www.earth.com/news/the-window-to-avoid-dangerous-global-warming-is-narrowing/">global</a> cooling phenomenon was erased by subsequent human-caused global warming.

“Today, the Earth is warming about 20 times faster than it cooled during the past 1,800 years,” said Michael Evans, second author of the study and an associate professor in the University of Maryland’s Department of Geology and Earth System Science Interdisciplinary Center (ESSIC). “This study truly highlights the profound effects we are having on our climate today.”

Compared to the atmosphere, the oceans can absorb much more heat and trap it for longer periods of time. Thus the <a href="https://www.bing.com/search?q=ocean&amp;cvid=62049be582284d8ab101b0a5aaaea521&amp;FORM=ANAB01&amp;PC=HCTS">ocean</a> can buffer short-term changes in global temperature. But when events such as volcanic eruptions cluster together in a relatively short period of time, the temperature changes can become prolonged.

“Volcanic eruptions have a short-term cooling effect on the atmosphere, but our results showed that when volcanic eruptions occurred more frequently, there was long-term ocean cooling,” said lead author Helen McGregor, an Australian Research Council (ARC) Future Fellow at the University of Wollongong in Australia. “With this research, we now have new insight into the century-scale global sea-surface temperature variations that came before man-made greenhouse gas forcing.”

The scientists are the first to combine 57 previously published marine surface temperature reconstructions that cover all of the world’s oceans, from near-polar to tropical regions. The team compiled the data within 200-year brackets to observe long-term trends, and then compared the findings to land-based reconstructions, which revealed similar cooling trends.

“No matter how we divided the data set, the cooling trend stands out as a robust signal,” McGregor said.

To investigate the cause of the cooling trend, the researchers turned to climate models. They examined how sea-surface temperatures reacted to various “forcing” factors, such as changes in solar output, Earth’s orbit, land use, volcanic activity and greenhouse gases. Only volcanic events resulted in a cooling trend that matched the team’s real-world observations.

Understanding how forcing factors changed ocean temperatures in the past can open a window into future climate change.

“Model simulations by others have shown us that the oceans can impart a substantial delay in the warming of the surface climate,” said Evans, who is also the lead of the Ocean2k working group of the Past Global Changes (PAGES) program. “With much of the heat from global warming entering our oceans, recent ocean surface warming may foreshadow additional future warming, in the same way ocean cooling appeared as a long-term response to large and frequent volcanic events in recent centuries.”

“We are still learning how the oceans mediate climate variations,” Evans added. “Further work combining both observations and simulations of ocean climate will refine our understanding of the ocean's role in climate change.”

EPA Downplays Gold King Mine Spill Danger. More than two weeks after the Gold King mine spill fouled waterways in several Western states, officials expressed concern Thursday over the long-term effects of contaminated river bottoms as the federal agency that triggered the accident downplayed the dangers.
U.S. Environmental Protection Agency workers released more than 3 million gallons of contaminated water Aug. 5 while investigating an inactive mine site near Silverton, <a href="https://www.bing.com/search?q=colorado&amp;cvid=fec366068ea545b38cdc7720af0ddf39&amp;FORM=ANAB01&amp;PC=HCTS">Colorado</a>. The spill prompted the shutdown of public drinking-water systems and left rivers in the regiadoon tinged a disturbing yellow-orange color that has since faded.EPA Downplays Gold King Mine Spill Danger
The EPA said in recent days that poisons including lead and thallium have been detected in river sediment samples collected from the Animas River, which travels from Colorado into northern New Mexico, joining the San Juan River before emptying into Lake Powell along the Utah-Arizona border.
In Colorado, contaminants exceeding drinking-water standards were found in seven private wells out of more than 100 tested, according to the EPA. Details on what contaminants were found and at what concentrations were not disclosed. Officials said Thursday that they would continue to investigate the wells, but noted that it was not clear if the spill was to blame.
EPA officials have repeatedly said sediment contamination was returning to pre-spill levels and no longer threatens recreational river users on the upper Animas or water treatment plants.
But state health officials were more cautious as they attempted to nail down the potential for long-term damage to private drinking wells and aquatic life, from the heavy metals and other contaminants that dropped out of the passing plume.
Experts warn that sediments could be stirred up from river bottoms by storms or during the annual spring runoff, when snow at high elevations in the Rocky Mountains melts.
The sediment contains thallium, a naturally occurring metal that can cause hair loss and kidney or liver problems, as well as lead, which can delay mental development in children.
"We are concerned about this particular sediment load given how the various constituents in the sediment may continue to affect the stream," Colorado health officials said in a statement released by Jan Stapleman, spokeswoman for the state Department of Public Health and the Environment.
The officials added that there was "ongoing potential for those (private) wells to be affected as the sediment migrates into the groundwater table." It could take years to gather enough data to accurately gauge the extent of problems for fish and other aquatic life, they said.
In Utah, scientists from the state Department of Environmental Quality said tests to date suggested the water in the <a href="http://www.earth.com/news/men-marijuana-higher-sperm-counts/">San Juan</a> River presents little health risk to users. Agency officials said they were turning to a long-term monitoring strategy focusing on sediment and what, if any, steps can be taken to deal with it.
In the interim, Utah health officials warned river visitors not to drink the water and to minimize contact with dirt and sand.
In New Mexico, environmental regulators monitoring the sediment said the threat it posed was an "open question" that required long-term investigation.
After tumbling from the heights of Colorado's Rockies, the Animas slows as it enters New Mexico, allowing more sediment to drop out of the water column and onto the river bottom, said Bruce Yurdin, a water quality expert with the New Mexico Environment Department.
Contaminants can be taken up by insects living on the bottom, which are then consumed by fish and ultimately by people fishing on the popular waterway.
Yet it could be difficult to distinguish problems caused by the EPA's spill from the long history of contamination flowing from upstream mines, Yurdin said.
Thirty-eight private water wells have been sampled in New Mexico, according to the EPA. Results of those tests were not provided.
Arizona wildlife officials planned to test the tissue of fish from Lake Powell for potential contaminants.
Despite repeated requests from The Associated Press, the EPA has not released further information on the pre-spill contamination levels in the Animas and San Juan rivers, which would shed light on how much things have changed.
EPA spokeswoman Lisa McClain-Vanderpool said the agency planned to release more information on sediments soon.
Navajo President Russell Begaye visited Silverton over the weekend and poured water over sediment settling on the banks of the river. He watched as yellowish sediment flowed over the rocks and downstream.
"These are things I'm concerned about, is what happens when the rain comes," Begaye said in a video posted on his office's Facebook page.
Tribal spokesman Mihio Manus said the president was considering lifting an advisory Saturday against using the San Juan River for irrigation. The EPA planned to end water deliveries for agriculture to the reservation on Friday.
The Interior Department, which is conducting an independent review of the spill at the EPA's request, said Thursday that it expects to deliver a final report by late October.
The probe will be overseen by Interior's Bureau of Reclamation.

EPA Downplays Gold King Mine Spill Danger

EPA Downplays Gold King Mine Spill Danger. More than two...

Tar Sands Battle

Battle Looms Over The First US Tar Sands Mine Set To Open In Utah. On a remote <a href="http://www.earth.com/image/great-salt-lake-in-northern-utah/">Utah</a> ridge covered in sagebrush, pines and wild grasses, a Canadian company is about to embark on something never before done commercially in the United States: digging sticky, black, tar-soaked sand from the ground and extracting the petroleum.
The impending opening of the nation's first tar sands mine has become another front in the battle across the West between preservationists and the energy industry.
U.S. <a href="https://www.bing.com/search?q=oil&amp;cvid=a230c5a104fd45e99b37113784c7bfb8&amp;FORM=ANAB01&amp;PC=HCTS">Oil</a> Sands has invested nearly $100 million over the last decade to acquire rights to about 50 square miles, obtain permits and develop what it says is a brand-new, non-toxic method of separating out the oil with the use of an orange-peel extract similar to what's in citrus-scented household soaps and detergents.Battle Looms Over The First US Tar Sands Mine Set To Open In Utah
"We're dedicated to having the world's most environmentally responsible oil sands project ever built," CEO Cameron Todd said in a boast that has failed to reassure protesters.

Across the rolling green hills of the Book Cliffs of eastern Utah, about 165 miles from Salt Lake City, the company plans this fall to begin digging the first in a series of pits, each the size of a football stadium, and start unsticking oil from the sand that crumbles in your hand like a brownie.
Tar sands, also called bitumen, are naturally occurring deposits of petroleum. Unlike the oil that flows out of wells, the hydrocarbons in tar sands must first be separated from the dirt by mixing the stuff with hot water and solvent. The oil is then sold to refineries for eventual use as fuel or an industrial ingredient.
Oil production from tar sands has been going on for years in Canada and Venezuela. The Canada-to-Texas Keystone XL pipeline that has been blocked by the Obama administration is supposed to carry tar sands oil.
While tar sands mining involves higher operating costs than traditional drilling, it can be highly profitable, especially when crude prices are high. But whether U.S. Oil Sands can make any money on this project remains to be seen.


[caption id="attachment_2383960" align="alignleft" width="150"]<a href="http://cff1.greenatom.net/uploads/2015/08/21142532/tar-sands-mine-utah-protestors_2big_ap.jpg"><img class="size-thumbnail wp-image-2383960" src="http://cff1.greenatom.net/uploads/2015/08/21142532/tar-sands-mine-utah-protestors_2big_ap-150x150.jpg" alt="Chipmunk mask-wearing protesters sit outside the U.S. Oil Sands commercial tar sands operation, in the Book Cliffs, in eastern Utah. " width="150" height="150" /></a> Chipmunk mask-wearing protesters sit outside the U.S. Oil Sands commercial tar sands operation, in the Book Cliffs, in eastern Utah.[/caption]
What looked like a shortage of oil when the company began raising money has now become a glut, in part because energy companies have learned to extract petroleum from formations long thought out of reach.
By the company's own estimate, it will make little to nothing at crude oil's current price of $48 per barrel, down from a peak of $147 in 2008. As of Tuesday, U.S. Oil Sands stock was trading at just 12 cents.
Protesters have tried to thwart the mine's construction for two summers in a row and have gotten arrested for chaining themselves to equipment. They argue that the project is an eyesore and that it could contaminate nearby springs and ruin habitat for deer, beaver and bears.
The mine sits on a cleared swath of land enclosed by barbed wire, with modular buildings, bulldozers, large metal posts and rails and a massive metal cylinder with a cone-shaped bottom where the tar sand mixing will be done.
Demonstrators who have been camping out all summer near the site gathered outside the front gate on a recent day to show their opposition. Some wore chipmunk masks. Other banged drums. Some held signs with messages such as "Dirty Energy Kills."

"It's heartbreaking to see what they've been doing out here," said Melanie Martin of the Tar Sands Resistance Movement. "It's impossible to reclaim and rehabilitate the land once they do what they are planning to do with it. The land is not going to come back for millennia."
Opponents also worry the mine will spur more projects in this pristine area that attracts hikers, campers and hunters. A 45-mile, $86 million highway as smooth as an autobahn has been built out to the mine. And the state has given approval for three other tar sands operations in the same corner of Utah.
Instead of relying on the usual industrial-strength hydrocarbon solvent, U.S. Oil Sands says it will employ the biodegradable citrus extract that is in grease-cutting household products.
Utah officials who recently approved the mine also imposed a key requirement environmentalists considered a victory: The company must monitor water and air quality.


[caption id="attachment_2383955" align="alignleft" width="150"]<a href="http://cff1.greenatom.net/uploads/2015/08/21142520/tar-sands-mine-utah_1big_ap.jpg"><img class="size-thumbnail wp-image-2383955" src="http://cff1.greenatom.net/uploads/2015/08/21142520/tar-sands-mine-utah_1big_ap-150x150.jpg" alt="Doug Thornton with U.S. Oil Sands, looks at the sticky, black, tar-soaked sand " width="150" height="150" /></a> Doug Thornton with U.S. Oil Sands, looks at the sticky, black, tar-soaked sand[/caption]
And instead of leaving open pits, ponds of mining debris and barren land, U.S. Oil Sands says it will fill in the holes with the clean leftover sand and plant grass and other vegetation.
U.S. Oil Sands estimates there are 180 million barrels of oil close to the surface on the land it is leasing. It plans to begin turning out 2,000 barrels per day later this year - a puny share of the 9.3 million the U.S. produces daily - and take it by truck to refineries. It says the mine will create about 50 full-time jobs when opened.
"This is a breakthrough in technology," Todd said by telephone from Calgary. "If we're able to demonstrate to the investment world that this is possible, there are many, many places where this could be done."
Alex Beeker, an industry research analyst, said he doesn't expect the mine to set off an explosion of tar sands mining in the U.S., where the prospects are basically limited to Utah. "But if U.S. Oil Sands starts to do very well, you're going to see more operators try to mimic what they're doing," he said.

Battle Looms Over The First US Tar Sands Mine Set...

Documents Show EPA Was Aware Of 'Blowout' Potential At Gold King Mine. Internal documents released late Friday show managers at the U.S. Environmental Protection Agency were aware of the potential for a catastrophic "blowout" at an abandoned Gold King mine that could release "large volumes" of wastewater laced with toxic heavy metals.
<a href="https://www.bing.com/search?q=EPA&amp;cvid=24c5289c519d466385a20f925b206a75&amp;FORM=ANAB01&amp;PC=HCTS">EPA</a> released the documents following weeks of prodding from The Associated Press and other media organizations. EPA and contract workers accidentally unleashed 3 million gallons of contaminated wastewater on Aug. 5 as they inspected the idled Gold King Mine near Silverton, <a href="http://www.earth.com/image/cameron-peak-fire-is-now-the-largest-in-colorados-recorded-history/">Colorado.</a>
Among the documents is a June 2014 work order for a planned cleanup that noted that the old mine had not been accessible since 1995, when the entrance partially collapsed. The plan appears to have been produced by Environmental Restoration, a private contractor working for EPA.Documents Show EPA Was Aware Of 'Blowout' Potential At Gold King Mine
"This condition has likely caused impounding of water behind the collapse," the report says. "ln addition, other collapses within the workings may have occurred creating additional water impounding conditions. Conditions may exist that could result in a blowout of the blockages and cause a release of large volumes of contaminated mine waters and sediment from inside the mine, which contain concentrated heavy metals."
A subsequent May 2015 action plan for the mine also notes the potential for a blowout.
There are at least three ongoing investigations into exactly how EPA triggered the disaster, which tainted rivers in Colorado, New Mexico and Utah with lead, arsenic and other contaminates. EPA says its water testing has shown contamination levels have since fallen back to pre-spill levels, though experts warn the heavy metals have likely sunk and mixed with bottom sediments that could someday be stirred back up.
The documents, which the agency released about 10:30 p.m. eastern time, do not include any account of what happened immediately before or after the spill. The wastewater flowed into a tributary of the Animas and San Juan rivers, turning them a sickly yellow.
Elected officials in affected states and elsewhere have been highly critical of the EPA's initial response. Among the unanswered questions is why it took the agency nearly a day to inform local officials in downstream communities that rely on the rivers for drinking water.
Much of the text in the documents released Friday was redacted by EPA officials. Among the items blacked out is the line in a 2013 safety plan for the Gold King job that specifies whether workers were required to have phones that could work at the remote site, which is more than 11,000 feet up a mountain.
EPA did not immediately respond Friday night to questions from the AP. In the wake of the spill, it has typically taken days to get any detailed response from the agency, if at all.
On its website, contractor Environmental Restoration posted a brief statement last week confirming its employees were present at the mine when the spill occurred. The company declined to provide more detail, saying that to do so would violate "contractual confidentiality obligations."
The EPA has not yet provided a copy of its contact with the firm. On the March 2015 cost estimate for the work released Friday, the agency blacked out all the dollar figures.

Farmers Markets And Food Coops Are Becoming More Popular. University of Iowa study finds local food movement rooted in relationships and values

More Americans than ever before are supporting their local farmers markets, and it's not just because they believe the food is fresher and tastes better.

According to a new University of Iowa study, people are shopping farmers markets and joining food coops at record numbers because they enjoy knowing who grows their food. These so-called "locavores" are also driven to eat locally grown produce and meat because their commitment to do so makes them feel a part of something greater than themselves - a community that shares their passion for a healthy lifestyle and a <a href="http://www.earth.com/news/new-discovery-could-provide-sustainable-freshwater-to-volcanic-islands/">sustainable</a> environment. Farmers Markets And Food Coops Are Becoming More Popular

For these enthusiasts, supporting the local food movement is a sort of civic duty, an act to preserve their local economy against the threats of globalization and big-box stores.

"It's not just about the economical exchange; it's a relational and ideological exchange as well," said Ion Vasi, an associate professor with a joint appointment in the Department of <a href="https://www.bing.com/search?q=Sociology&amp;cvid=f66c94e4734a43f195c8f6ab20853621&amp;FORM=ANAB01&amp;PC=HCTS">Sociology</a> and Tippie College of Business at the UI and corresponding author of the study.

Vasi said the local food market is what sociologists call a "moralized market," that is a market in which people combine economic activities with their social values. Among their findings, the UI researchers discovered local food markets were more likely to develop in areas where residents had a strong commitment to civic participation, health and the environment.

"It's about valuing the relationship with the farmers and people who produce the food and believing that how they produce the food aligns with your personal values," Vasi said.

Vasi shared the results of the study August 22 at the American Sociology Association Annual meeting in Chicago.

For his study, Vasi examined the development of local food markets by looking at the number of farmers markets, food coops, community-supported agriculture providers and local food restaurants in cities across the United States. Researchers also conducted 40 interviews with consumers and producers in different local food markets in Iowa and New York.

From a historical perspective, the recent growth of local food markets is rather surprising.

In 1971, Jane Pyle predicted farmers markets were "doomed by a changing society" in an article penned for The Geographical Review. At the time, there were about 340 farmers markets left in the United States and many were "populated by resellers, not farmers, and were on the verge of collapse," Pyle wrote.

Some 20 years later, the tide was beginning to turn.

According to the United State Department of Agriculture, national direct-to-consumer food sales increased three-fold between 1992 and 2007, growing twice as fast as total agricultural sales. The number of farmers markets listed in the USDA National Farmers Markets increased from 3,706 in 2004 to 8,268 in 2014. Plus, UI researchers found the number of Internet searches for farmers markets has almost tripled during that same 10-year period and the number of newspaper articles that mention farmers markets has almost quadrupled.

So, what's behind this need to know who grows your food and to believe in how it's produced?

It was the onslaught of big-box stores and globalization forces that reignited "buy local" campaigns across the country in the 1990s, said the UI researchers.

According to the study: "A growing number of communities have attempted to gain control of their own economies by encouraging civic engagement that supports investing in locally owned businesses instead of outside companies."

Sara Rynes, a professor of Management &amp; Organizations in the UI's Tippie College of Business, and co-author of the study, said the researchers also found that local food markets, whether farmers markets, food coops or otherwise, were more likely to be located in cities and counties with higher education levels, higher income levels and more institutions of higher education.

"Sociologists and political scientists have argued that higher income allows people to make consumption decisions based on values in addition to matters of price or value," Rynes said. "Education is likely to facilitate knowledge about such things as links between the way products are produced and their environmental and health impacts. And universities sometimes get involved in helping local farmers and individuals who are struggling to make a living, particularly through extension efforts."

"It's not just about the economical exchange; it's a relational and ideological exchange as well," said Ion Vasi, an associate professor with a joint appointment in the Department of Sociology and Tippie College of Business at the UI and corresponding author of the study.

Vasi said the local food market is what sociologists call a "moralized market," that is a market in which people combine economic activities with their social values. Among their findings, the UI researchers discovered local food markets were more likely to develop in areas where residents had a strong commitment to civic participation, health and the environment.

"It's about valuing the relationship with the farmers and people who produce the food and believing that how they produce the food aligns with your personal values," Vasi said.

Vasi shared the results of the study August 22 at the American Sociology Association Annual meeting in Chicago.

For his study, Vasi examined the development of local food markets by looking at the number of farmers markets, food coops, community-supported agriculture providers and local food restaurants in cities across the United States. Researchers also conducted 40 interviews with consumers and producers in different local food markets in Iowa and New York.

From a historical perspective, the recent growth of local food markets is rather surprising.

In 1971, Jane Pyle predicted farmers markets were "doomed by a changing society" in an article penned for The Geographical Review. At the time, there were about 340 farmers markets left in the United States and many were "populated by resellers, not farmers, and were on the verge of collapse," Pyle wrote.

Some 20 years later, the tide was beginning to turn.

According to the United State Department of Agriculture, national direct-to-consumer food sales increased three-fold between 1992 and 2007, growing twice as fast as total agricultural sales. The number of farmers markets listed in the USDA National Farmers Markets increased from 3,706 in 2004 to 8,268 in 2014. Plus, UI researchers found the number of Internet searches for farmers markets has almost tripled during that same 10-year period and the number of newspaper articles that mention farmers markets has almost quadrupled.

So, what's behind this need to know who grows your food and to believe in how it's produced?

It was the onslaught of big-box stores and globalization forces that reignited "buy local" campaigns across the country in the 1990s, said the UI researchers.

According to the study: "A growing number of communities have attempted to gain control of their own economies by encouraging civic engagement that supports investing in locally owned businesses instead of outside companies."

Sara Rynes, a professor of Management &amp; Organizations in the UI's Tippie College of Business, and co-author of the study, said the researchers also found that local food markets, whether farmers markets, food coops or otherwise, were more likely to be located in cities and counties with higher education levels, higher income levels and more institutions of higher education.

"Sociologists and political scientists have argued that higher income allows people to make consumption decisions based on values in addition to matters of price or value," Rynes said. "Education is likely to facilitate knowledge about such things as links between the way products are produced and their environmental and health impacts. And universities sometimes get involved in helping local farmers and individuals who are struggling to make a living, particularly through extension efforts."

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.

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.
