High Mountain Asia, often called the “Third Pole,” holds the largest store of ice outside the Arctic and Antarctic. Its glaciers have shaped landscapes, nourished rivers, and sustained communities for thousands of years. But today, these frozen giants are shrinking at a troubling pace. 



Scientists have long agreed that warming temperatures drive the <a href="https://www.earth.com/news/half-of-the-worlds-glaciers-can-be-saved-with-strong-climate-action/">retreat</a>, yet new evidence reveals another culprit: shifting rainfall and snowfall patterns, especially those tied to the South Asian monsoon.



<h2 class="wp-block-heading" id="h-glaciers-losing-ice-faster">Glaciers losing ice faster</h2>



The numbers are staggering. Glaciers across the region are losing more than 22 gigatons of ice each year, equivalent to nearly nine million Olympic swimming pools. 



While rising temperatures explain much of the retreat, researchers from the <a href="https://www.utah.edu" target="_blank" rel="noreferrer noopener">University of Utah</a> and <a href="https://www.vt.edu" target="_blank" rel="noreferrer noopener">Virginia Tech</a> show that the timing and type of precipitation now play a major role. Rain falling instead of snow fuels melt, and shorter or weaker monsoon seasons reduce the ice that glaciers can accumulate.



“These findings highlight that glaciers dominated by the South Asian monsoons, such as the Central Himalaya, Western Himalaya and Eastern Himalaya, are especially vulnerable,” said Sonam Sherpa, assistant professor at the University of Utah and lead author of the study. 



“If the timing and intensity of the monsoon continues to alter, it could accelerate <a href="https://www.earth.com/news/glaciers-from-the-rockies-to-the-alps-are-melting-much-faster-than-expected/">ice</a> loss and threaten water availability for millions downstream.”



<h2 class="wp-block-heading" id="h-billions-rely-on-glacier-water">Billions rely on glacier water</h2>



The glaciers of High Mountain Asia supply freshwater to more than 1.4 billion people. These rivers sustain agriculture, hydropower, and drinking water across South and Central Asia. 



As glaciers retreat more rapidly, rivers will depend less on glacial melt and increasingly on rainfall as their main source of water.



“Looking ahead, a faster retreat of mountain glaciers will shift the main source of river flow from <a href="https://www.earth.com/news/glaciers-are-melting-from-hidden-underwater-waves/">glacier</a> melt to rainfall, thereby heightening the risk of droughts in downstream regions for future generations,” said Susanna Werth, assistant professor at Virginia Tech and co-author of the study.



<h2 class="wp-block-heading" id="h-monsoon-impacts-on-glaciers">Monsoon impacts on glaciers</h2>



To understand these shifts, the researchers used satellite gravimetry from NASA’s GRACE and GRACE-FO missions. These satellites can “weigh” changes in water storage, including ice, by measuring gravity variations.



Scientists corrected the data to account for groundwater use, soil moisture, surface water, and snow. They paired this with climate reanalysis models, dividing the year into four phases: winter, premonsoon, monsoon, and postmonsoon. 



By analyzing rainfall and <a href="https://www.earth.com/news/glacier-melting-threatens-global-water-supplies-and-coastal-communities/">snowfall</a> separately, they revealed how timing and precipitation type affect glacier mass.



<h2 class="wp-block-heading" id="h-monsoon-timing-speeds-ice-loss">Monsoon timing speeds ice loss</h2>



The experts found that glaciers respond more strongly to seasonal precipitation than to annual totals. 



Cycles repeating every 3 to 4.5 years and 5 to 8 years match the natural rhythm of South Asian monsoons. In the Central Himalaya, glacier loss was tied to reduced premonsoon rainfall.



In the Eastern Himalaya, declining postmonsoon snowfall accelerated retreat. In the Western Himalaya, increased summer rain caused rain-on-ice events that sped melting. These details show that the seasonality of rain and snow is as important as overall precipitation amounts.



<h2 class="wp-block-heading" id="h-glacier-loss-differs-by-region">Glacier loss differs by region</h2>



Different climate systems influence each subregion. Monsoon-fed glaciers in the Central and Eastern Himalaya show the highest rates of ice loss.



Glaciers dominated by the Westerlies, such as those in the Pamir–Hindu Kush and Karakoram, show slower declines or in some cases slight gains.



The Tien Shan, influenced by Siberian systems and western cyclones, also shows significant losses. These contrasts highlight how winds and precipitation phase shifts shape glacier health differently across the mountains.



<h2 class="wp-block-heading" id="h-hazards-on-the-rise">Hazards on the rise</h2>



Rapid melting brings hazards that are both immediate and long-term. Glacial lake outburst floods are becoming more common as ice retreats, creating unstable lakes held back by fragile moraine walls. Landslides and river floods often follow, putting downstream communities at risk.



“This risk is not only about long-term water shortages but also about immediate threats to lives and infrastructure,” said Sherpa.



<h2 class="wp-block-heading" id="h-glacier-loss-under-stronger-monsoons">Glacier loss under stronger monsoons</h2>



Climate projections suggest stronger and more intense monsoons in the coming decades, with possible changes in their timing. 



By 2100, ice loss in monsoon-dominated basins could reach 38–58 percent, depending on future emissions.



Such a shift would profoundly affect river flows, agriculture, and disaster risks. The study emphasizes that improved monitoring networks are urgently needed to capture rain, snow, and temperature changes across high-altitude regions.



<h2 class="wp-block-heading" id="h-protecting-communities-downstream">Protecting communities downstream </h2>



High Mountain Asia’s glaciers are retreating under the combined weight of heat and shifting monsoons. Seasonal timing and the balance of rain versus snow now shape their fate more than annual totals. 



Protecting communities downstream will require better observation and planning that accounts for these seasonal fingerprints. 



The research makes clear that what happens in these mountains will ripple far beyond their valleys, potentially impacting the lives of more than a billion people.

Shrinking glaciers in the Himalayas are not just threatened by heat

Its glaciers have shaped landscapes, nourished rivers, and sustained communities for thousands of years. But today, these frozen giants are shrinking at a troubling pace.

Plants need more nitrogen to combat climate change. Plants can grow faster as atmospheric carbon dioxide concentrations increase, but only if they have enough nitrogen or partner with fungi that help them get it, according to new research published this week in Science.

The study was led by César Terrer Moreno, a Ph.D. student at Imperial College London, and included researchers from <a href="http://www.nau.edu" target="_blank" rel="noopener noreferrer">Northern Arizona University</a>, the University of Antwerp (Belgium), Indiana University and New South Wales University (Australia).

The team synthesized more than 80 past experiments and found that higher CO2 boosted plant growth, as long as the plants received enough nitrogen. Without added nitrogen, CO2 had no effect, confirming the long-standing idea that nitrogen limits plant response to rising CO2. But there was a major exception: some plants--those with specialized partnerships with soil fungi--were able to respond to the extra CO2, just as much as if they had been fertilized with nitrogen. Plants need more nitrogen to combat climate change

"Nitrogen and mycorrhizae are like the X-factors in plant responses to CO2," said Bruce Hungate, Director of NAU's Center for Ecosystem Science and Society and Regents' Professor of Biological Sciences, who was a co-author on the study. "Rising CO2 is not a universal fertilizer, but neither is nitrogen limitation a universal restriction on the CO2 response. The truth is in the middle, and microbes are the key mediators," Hungate said.

Most plants associate with mycorrhizal fungi, a partnership in which the fungus provides the plant with nutrients and water and receives food from the plant in return. But not all mycorrhizae are the same. Arbuscular mycorrhizal fungi specialize in taking up phosphorus from the soil, but not nitrogen, and plants that associated with arbuscular mycorrhizae were unable to respond to CO2 unless extra nitrogen was added. It was the plants that form ectomycorrhizal partnerships that responded to extra CO2 without any added nitrogen fertilizer, because these fungi produce enzymes that liberate bound nitrogen from soil organic matter, and the fungi can take up the nitrogen and pass some along to the plant.

This synthesis helps resolve a long-standing debate about the role of nitrogen limitation for plant responses to CO2. Without enough nitrogen, it is thought that plants will be unable to respond much to rising CO2, and many experiments support this idea. But in some experiments where nitrogen is in short supply, the plants still grow more with elevated CO2, and the reasons have puzzled scientists for many years. The new synthesis offers a clear answer: "Plants need nitrogen to respond to high CO2, whether they find it readily available in the soil, or whether their mycorrhizal partners can help them get it," explained Hungate.

The research should help project climate change into the future. Forests, grasslands and other ecosystems around the world currently absorb about 30 percent of human CO2 emissions, without which climate change would be happening even faster than it is now. The future of this terrestrial carbon sink depends on carbon accumulation by ecosystems through plant growth. This new research shows that it is essential to take into account mycorrhizal fungi, and suggests that the next generation of global carbon cycle models should include mycorrhizae as an important control point on plant responses to rising CO2 in the atmosphere. It is well known that grasses and herbs form arbuscular mycorrhizae, and that many trees form ectomycorrhizae. Since global carbon cycle models already recognize these different plant forms, adding mycorrhizae to models of the carbon cycle should be straightforward, and the team is already moving toward that goal.

Fukushima disaster and the oceans: What do we know, 5 years on?. A major international review of the state of the oceans 5 years after the Fukushima disaster shows that radiation levels are decreasing rapidly except in the harbour area close to the nuclear plant itself where ongoing releases remain a concern. At the same time, the review's lead author expresses concern at the lack of ongoing support to continue the radiation assessment, which he says is vital to understand how the risks are changing.

These are the conclusions of a major 5 year review, with multi-international authors who are all working together as part of a <a href="http://www.whoi.edu/CMER/rio5-working-group" target="_blank" rel="noopener noreferrer">Scientific Committee on Oceanic Research (SCOR) Working Group</a>. The report is being presented at the Goldschmidt geochemistry conference in Japan. The review paper is also published in Annual Review of Marine Science*. The main points made by the report are:
<ul>
 	<li>The accident. The Tohoku earthquake and tsunami on March 11, 2011 led to the loss of power and overheating at the Fukushima Daiichi Nuclear Power Plants (FDNPP), causing extensive releases of radioactive gases, volatiles and liquids, in particularly to the coastal ocean. The radioactive fall-out on land is well-documented, but the distribution of radioactivity in the seas and onto the wider oceans is much more difficult to quantify, due to variability in the ocean currents and greater difficulty in sampling.</li>
 	<li>Initial release of radioactive material. Although the FDNPP accident was one of the largest nuclear accidents and unprecedented for the ocean, the amount of 137Cs released was around 1/50th of that released by the fall out of nuclear weapons and 1/5th that released at Chernobyl. It is similar in magnitude to the intentional discharges of 137Cs from the nuclear fuel reprocessing plant Sellafield.</li>
 	<li>Initial fallout. The main release of radioactive material was the initial venting to the atmosphere. Models suggest that around 80% of the fallout fell on the ocean, the majority close to the FDNPP. There was some runoff from the land, peaking around 6 April 2011. There is a range of estimates of the total amount of 137Cs release into the ocean, with estimates clustering around 15-25 PBq (PetaBecquerel, which is 1015 Becquerel. One Becquerel is one nuclear decay per second). Other radioisotopes were also released, but the focus has been on radioactive forms of Cs given their longer half-lives for radioactive decay (134Cs = 2 yrs; 137Cs = 30 yrs) and high abundance in the FDNPP source.</li>
 	<li>Distribution in water. Cs is very soluble, so it was rapidly dispersed in the ocean. Prevailing sea currents meant that some areas received more fall-out than others due to ocean mixing processes. At its peak in 2011, the 137Cs signal right at the FDNPP was tens of millions of times higher than prior to the accident. Over time, and with distance from Japan, levels decrease significantly. By 2014 the 137Cs signal 2000km North of Hawaii was equivalent to around six times that remaining from fallout from atmospheric nuclear tests from the 1960's, and about 2-3 times higher than prior fallout levels along the west coast of N. America. Most of the fallout is concentrated in the top few hundred metres of the sea. It is likely that maximum radiation levels will be attained off the North American coast in the 2015-16 period, before declining to 1-2 Bq per cubic metre (around the level associated with background nuclear weapon testing) by 2020. Sea-floor sediments contain less than 1% of the 137Cs released by the FDNPP, although the sea-floor contamination is still high close to the FDNPP. The redistribution of sediments by bottom-feeding organisms (more common near the coast) and storms is complex.</li>
 	<li>Uptake by marine life. In 2011, around half the fish samples in coastal waters off Fukushima had radiocesium levels above the Japanese 100Bq/kg limit, but by 2015 this had dropped to less than 1% above the limit. High levels are still found in fish around the FDNPP port. High levels of 131I were measured in fish in April 2011, but as this has a short radioactive half-life, it is now below detection levels. Generally, with the exception of species close to the FDNPP, there seem to be little long-term measurable effects on marine life.</li>
 	<li>Risk to Humans. The radiation risk to human life is comparatively modest in comparison to the 15,000 lives were lost as a result to the Tohoku earthquake and tsunami. So far, there have been no direct radiation deaths. The most exposed FDNPP evacuees received a total dose of 70 mSv, which (if they are representative of the general population) would increase their lifetime fatal cancer risk from 24% to 24.4%. However, there are still over 100,000 evacuees from the Fukushima area, and many industries such as fishing and tourism have been badly hit.</li>
</ul>
Lead author, Dr. Ken Buesseler (Woods Hole Oceanographic Institution, USA) said:

"This report pulls together much of the academic, industry and government studies to form a more complete picture of the amount of radioactivity released, its fate and transport in the ocean, whether we should be worried or not, and what can be predicted for the future. Overall, the results show a trend of decreasing radiation risk in oceans themselves and to marine life. This is generally true, except for the harbour at Fukushima NPP. The highest remaining oceanic contamination remains in seafloor sediments off coast of <a href="https://en.wikipedia.org/wiki/Japan">Japan</a>.

Despite this, we are still concerned that there is little support to continue assessments as time goes by, in particular from the US federal agencies which have not supported any ocean studies. This is not good, as public concern is ongoing, and we can learn a lot even when levels go down in the environment, and are no longer of immediate health concern".

Prof. Bernd Grambow, Director of SUBATECH laboratory, Nantes, France and leader of the research group on interfacial reaction field chemistry of the ASRC/JAEA, Tokai, Japan, commented: "This report is an excellent summary of the impact and the fate of the release of radioactive substances to the ocean. While the distribution and impact of <a href="http://www.earth.com/video/how-to-remove-radioactive-waste-from-water/">radioactive</a> material becomes clearer with time, a lot of work still needs to be done. Discharge flux rates of Cs-137 to the ocean continue to be in the range of some TBq/yr. Forest and soil bound Cs-137 is only slowly being washed away, with waste piles accumulating in many places

The evolution of transfer mechanisms and the flux of radioactive material through soils, plants and food chain from land to ocean are still insufficiently understood and still deserve close attention of the international scientific community."

Ocean circulation slowed with every cooling during last ice age

Ocean circulation may cause abrupt climate changes. There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery. New evidence published this week in the leading journal Science shows for the first time that the ocean's overturning circulation slowed during every one of those temperature plunges - at times almost stopping.

"People have long supposed this link between overturning circulation and these abrupt climate events. This evidence implicates the ocean," said L. Gene Henry, the lead author of the study and a graduate student at Columbia University's Lamont-Doherty <a href="https://en.wikipedia.org/wiki/Earth">Earth</a> Observatory.

The impact of changes in the ocean overturning circulation on climate has become a hot topic today as global temperatures rise and melting sea ice and glaciers add freshwater to the North Atlantic. A 2015 study suggested that cooling in the <a href="http://www.earth.com/image/phytoplankton-blooms-persist-in-the-north-atlantic-ocean/">North Atlantic</a> may be due to a reduction in the overturning circulation, while a 2016 study suggested there had not been enough freshwater to have an effect.

The new study explores what happened to ocean circulation when the earth went through a series of abrupt climate changes in the past during a time when ice covered part of North America and temperatures were much colder than today. It looks at the Atlantic meridional overturning circulation, which distributes heat as it moves warmer surface water from the tropics toward Greenland and the high northern latitudes and carries colder, deeper water from the North Atlantic southward.

Using chemical tracers in sediment that builds up on the sea floor over time, Henry and his coauthors were able to document the relative speed of the Atlantic meridional overturning circulation during each abrupt climate change during the last ice age.

The chemical tracers show that the speed of the ocean overturning circulation changed first, and that sea surface temperature changed a while later. That suggests that cooling may start with changes in the ocean circulation, influencing the northern sea surface and atmosphere, said co-author Jerry McManus, a professor at Lamont-Doherty Earth Observatory. Evidence from ice cores and deep-sea sediment has shown that the northern climate also cooled before the southern climate during these abrupt changes, creating a "bipolar seesaw," with the north cool while the south was warm, and the south cooling as the north warmed.

The scientists stress that more work is needed to determine whether changes in ocean circulation initiated the abrupt climate changes or were an intermediary effect initially triggered by something else. "Our study supports the view that changes in ocean circulation were at least in part responsible for causing abrupt climate changes. However, what in turn caused those changes in circulation remains a mystery," Henry said.

Also unclear is why these abrupt climate shifts, also seen in previous ice ages, haven't happened in the past 10,000 years. The instability appears to occur only in certain temperature ranges, and when there is a large amount of land ice that could contribute freshwater.

"We would all like to understand better how the earth's climate operates," McManus said. "This demonstrates the crucial role that global circulation can play. The dynamics of the deep ocean directly influence the earth's climate."

The series of abrupt climate changes studied here occurred between 60,000 and 25,000 years ago, ending as the last ice age peaked. Each followed a general pattern in the Northern Hemisphere: The cooling happening over hundreds to 1,000 years, then the frigid temperatures persisted for a few hundred years in what is known as a stadial, McManus said. Once warming started, it happened very rapidly, with a rise of 3 to 6 degrees Celsius in average sea surface temperature and larger changes over Greenland within a span of decades.

During every cold northern stadial, the overturning circulation had slowed, so it wasn't bringing as much heat northward from the tropics and Southern Hemisphere, the study shows. The chemical tracers also suggest that circulation slowed almost to a halt during certain stadials known as Heinrich events, when massive amounts of icebergs broke off and drifted away from the Laurentide ice sheet, which covered a large part of North America at the time. Icebergs carry freshwater that can affect ocean circulation, and computer models have suggested that adding that much freshwater to the Atlantic could shut down circulation. Exactly what influence the icebergs had during these periods will be the target of future research.

To determine how ocean circulation changed, the scientists measured three types of chemical tracers. By comparing the ratio of protactinium-231 to thorium-230, two daughter isotopes of uranium decay that remain in seawater for relatively short but consistently different periods of time before drifting into the seafloor, they could determine when circulation was strongest. Another isotope, carbon-13, captured in tiny shells, is more common in North Atlantic waters than in southern waters. When circulation was strong, protactinium was low and carbon 13 was high, because more protactinium was carried away by the current and more northern waters formed.

Axel Timmermann, a professor of oceanography at the University of Hawaii who studies abrupt climate changes and was not involved in this study, called it a "breakthrough analysis."

"Large changes in the North Atlantic meridional overturning circulation are thought to have played a major role in generating millennial-scale global variability, known as Dansgaard-Oechger events, during the last glacial period. The paper by Henry, McManus and colleagues finally provides supporting evidence for this fundamental scientific hypothesis," Timmermann said.

A variety of normally harmless bacteria can cause bleaching disease in seaweeds when the seaweeds become stressed by high water temperatures, <a href="https://en.wikipedia.org/wiki/NASA">UNSW</a> Australia researchers have discovered.

Seaweeds are the "trees" of the ocean, providing vital habitat, food and shelter for many species of fish and other coastal marine <a href="http://www.earth.com/video/tiny-marine-organisms-may-affect-ocean-mixing/">organism</a>, such as crayfish and abalone.

"A lot of attention has been paid to coral bleaching, but seaweeds are also affected by temperature-related diseases," says study senior author UNSW's Dr Suhelen Egan.

"In most cases, the infectious agents that cause the diseases are unknown. Improving our understanding these disease processes is not only important for maintaining a healthy marine environment; it also has economic significance, given that seaweeds are increasingly being cultivated as sources of food and feed-stock for biofuels."

The study, by Dr Egan's team at the UNSW Centre of Marine Bio-Innovation, is published in the journal Environmental Microbiology.

The researchers collected samples of healthy and diseased red alga, Delisea pulchra, from about 8 metres under the water at different locations on the Sydney coastline. The diseased seaweeds had undergone natural bleaching, in which areas of pigment are lost.

"Bleaching reduces the ability of the seaweed to photosynthesise and harvest energy from the sun, and to reproduce. It also makes them more susceptible to grazing by fish and other herbivores in the ocean," says Dr Egan.

The researchers isolated microbes that were in greater abundance on the diseased seaweeds and cultured them. They then tested the ability of these microbes to cause bleaching disease in seaweeds in the laboratory.

"We were surprised to identify three very different kinds of bacteria which are usually present in low numbers on seaweeds, but which we now know can all cause the same bleaching disease," says Dr Egan.

"We also found that the usual balance of microbes was disturbed on the diseased seaweeds, with a lower diversity of microbes present than normal.

"We believe these kinds of opportunistic pathogens are more common in marine environment than had been realised before. They seize the chance to cause disease when the host is stressed, in the same way that normally harmless, common bacteria can cause disease in people who have weakened immune systems."

The three newly identified pathogens that cause the bleaching disease are members of the Alteromonas, Aquimarina and Agarivorans genera.

Toxic algae bloom invades Florida beaches. As a noxious algae bloom fouls beaches on Florida's Atlantic coast, the <a href="https://www.bing.com/search?q=u.s.+army+corps&amp;form=EDGEAR&amp;qs=PF&amp;cvid=01079f54837c4b47b2d838da065cf3b2&amp;cc=US&amp;setlang=en-US&amp;elv=AY3%21uAY7tbNNZGZ2yiGNjfNohb9CLHhC*AbSHwHQGaD3uTGsfYh*E0fmbM16UjamUs*m18FNrgGG*yBvlQDu7iG5vyVv*mQsglpf7zANuVx0&amp;plvar=0&amp;PC=HCTS">U.S. Army Corps</a> of Engineers is preparing to reduce the flow of water from Lake Okeechobee that many blame for fueling the problem.
The Corps' Jacksonville District planned to begin the reductions Friday, targeting the Caloosahatchee Estuary and the St. Lucie Estuary, a news release said. Toxic algae bloom invades Florida beaches
The action comes after Florida Gov. Rick Scott declared a state of emergency over the problem, and as politicians and residents are blaming the federal government.
Multiple Florida lawmakers have asked federal authorities that oversee Lake Okeechobee to immediately stop freshwater releases that coastal communities blame for algae blooms and other environmental damage.
"I would describe them as guacamole-thick. And it stinks," said Gabriella Ferraro, spokeswoman for Martin County.
<a href="http://www.earth.com/image/striking-antisolar-rays-over-florida/">Florida</a>'s U.S. senators, Republican Marco Rubio and Democrat Bill Nelson, have joined Martin County commissioners in calling for the Army Corps of Engineers to stop the flow of water between the river and Lake Okeechobee. Residents and business owners blame the algae on pollutants streaming from the lake.
After touring the St. Lucie River as it passes through downtown Stuart, Nelson said the problems can be traced to Florida's history of diverting water to the ocean.
"We need to repair 75 years of diking and draining, but that takes time," he said. He called on Florida's Legislature to spend money approved by state voters for environmental projects such as purchasing land around Lake Okeechobee for water storage instead of diverting the funds to pay for administrative costs.
Rubio is scheduled to visit the area Friday.
<img class="alignleft size-thumbnail wp-image-2400905" src="http://cff1.greenatom.net/uploads/2016/07/01101101/algae-bloom-florida-june2016_1big_ap-150x150.jpg" alt="algae-bloom-florida-june2016_1big_ap" width="150" height="150" />The blue-green algae is the latest contaminant featured in yearslong arguments over water flowing from Lake Okeechobee, which is critical to South Florida's water supply and flood control systems.
At Central Marine boat docks in Stuart, pea-green and brown algae coated the water Thursday and smelled strongly like cow manure. Blooms that started last week in the St. Lucie River continue to spread, threatening Atlantic beaches expecting crowds of families for the holiday weekend.
Sarah Chaney, a receptionist at Central Marine, said boaters and fisherman are cancelling reservations after seeing reports of the algae, which she called "horrible and disgusting."
When Scott declared a state emergency for the area Wednesday, he blamed the federal government for neglecting repairs to the lake's aging dike that's considered one of the country's most at-risk for imminent failure. On Thursday, he amended the emergency declaration, adding Lee and Palm Beach counties to Wednesday's emergency declaration for Martin and St. Lucie counties. Palm Beach County is located directly south of the existing emergency area, while Lee County is located on Florida's Gulf coast.
Some residents blamed Scott instead Thursday. He hasn't done enough to curb pollution from farms north of the lake or purchase land farther south where lake waters could be stored and cleaned, said Irene Gomes, owner of the Driftwood Motel in Jensen Beach.
The algae has rapidly grown from a beach nuisance to a health concern, as one customer made plans to leave early if the algae triggered breathing issues, said Gomes, whose family has owned the motel's turquoise-colored cabins since 1958.
"At one point, I could say to my customers, 'Come down, it's not at all the beaches,' because it wasn't toxic. Now we're talking about health issues," Gomes said.
Chaney, the Central Marine receptionist, said Scott should visit the area, even if he gets criticized.
"He needs to come see it himself and stop being a coward," she said.
Scott said in a news release Thursday that the Florida Department of Economic Opportunity will immediately activate a virtual business emergency operations center to assess businesses impacted by the blooms. The program will begin to survey businesses affected by the water releases and share the results with various state and local agencies to implement appropriate disaster relief programs.
Lake Okeechobee is the largest in Florida and the second largest body of freshwater in the contiguous United States. Flooding there after a major hurricane in 1928 killed at least 2,500 people in surrounding communities of mostly poor, black farmworkers. It inspired the storm central to Zora Neale Hurston's novel "Their Eyes Were Watching God."
To reduce the risk of a breach in the dike built after that hurricane, the Corps of Engineers tries to keep lake water levels between 12.5 feet and 15.5 feet above sea level. Shoring up the dike will take years. Meanwhile, freshwater is released east and west of the lake into the Caloosahatchee and St. Lucie rivers.
State water managers have said local stormwater runoff and septic tanks also fuel algae blooms. They're working to direct more water south of Lake Okeechobee into the parched Everglades, but federal regulations, conservation mandates and stalled restoration projects complicate those efforts.
In neighboring St. Lucie County, home to the troubled Indian River Lagoon, officials have prohibited homeowners from using fertilizer during the summer and begun working with the state to test waterways for pollution that might be linked to septic tanks.
Murky waters on southwest Florida's Gulf Coast also are blamed on the lake's discharges. Fort Myers-area lawmakers said Thursday that Scott should extend the state of emergency to Lee County because of water issues in the Caloosahatchee River.

Scientists: Environmental toxins hurt brain development. An unprecedented alliance of leading scientists, medical experts, and children's health advocates argue that today's scientific evidence supports a link between exposures to environmental <a href="https://www.earth.com/news/high-levels-of-toxins-found-in-stranded-whales-and-dolphins/">toxins</a> in air, food, and everyday products and children's risks for neurodevelopmental disorders. The alliance, known as Project TENDR, which stands for "Targeting Environmental Neuro-Developmental Risks," is calling for immediate action to significantly reduce exposures to toxic chemicals to protect brain development.

Among the signatories to the TENDR statement published online in Environmental Health Perspectives are Frederica Perera, professor and director of the Columbia Center for Children's Environmental Health, and Virginia Rauh, professor of Population and Family Health, both faculty at Columbia University's Mailman School of Public Health. Scientists: Environmental toxins hurt brain development

"There is overwhelming scientific evidence that early-life exposure to neurotoxic chemicals is contributing to a host of developmental problems in children," says Perera, a professor of Environmental Health Sciences. "Exposure to these <a href="https://www.bing.com/search?q=chemicals&amp;cvid=c9b0b768100249a8a327d9b6b43d9526&amp;FORM=ANAB01&amp;PC=HCTS">chemicals</a> is pervasive, warranting action now to reduce their production and use."

Neurodevelopmental disorders linked to certain environmental exposures include intellectual disability, autism spectrum disorder, attention deficits, hyperactivity, and learning disabilities.

Prime examples of the chemicals and pollutants that are contributing to children's learning, intellectual and behavioral impairment include:
<ul>
 	<li>Organophosphate (OP) pesticides</li>
 	<li>Polybrominated diphenyl ether (PBDE) flame retardants</li>
 	<li>Combustion-related air pollutants, which generally include polycyclic aromatic hydrocarbons (PAHs), nitrogen dioxide and particulate matter</li>
 	<li>Lead</li>
 	<li>Mercury</li>
 	<li>Polychlorinated Biphenyls (PCBs)</li>
</ul>
TENDR signatories call on government to remove these toxic chemicals from food and consumer products so that pregnant women and children are not exposed. In addition, they call on regulators to follow scientific guidance for assessing how chemicals affect brain development, such as taking into account the special vulnerabilities of the developing fetus and children, all sources of exposure to neurotoxic chemicals, and the lack of a safety threshold for many of these chemicals. Among action items, they call on businesses to eliminate chemicals harmful to brain development from their supply chains and products.

Project TENDR, which stands for "Targeting Environmental Neuro-Developmental Risks," is an alliance of 48 of the nation's top scientists, health professionals and health advocates. TENDR participants have come together across many disciplines and sectors, including epidemiology, toxicology, exposure science, pediatrics, obstetrics and gynecology, nursing, public health, and federal and state chemical policy. Medical and scientific societies that have signed on in support include American Congress of Obstetricians and Gynecologists, Endocrine Society, National Medical Association, National Hispanic Medical Association and the National Council of Asian Pacific Island Physicians. TENDR's long-term mission is to lower the incidence of neurodevelopmental disorders by reducing exposure levels to chemicals and pollutants that can contribute to these conditions, especially during fetal development and early childhood. Project TENDR is a joint endeavor of the Learning Disabilities Association of America (LDA) and the University of California Davis MIND Institute (Medical Investigations of Neurodevelopmental Disorders).

NASA scans powerful Typhoon Nepartak. NASA's Aqua satellite passed over Typhoon Nepartak after it became a major typhoon in the Northwestern Pacific Ocean.

The second tropical cyclone of the northwestern Pacific Ocean season formed on July 3 and strengthened quickly into a tropical storm that was named Nepartak.

On July 5 at 0359 UTC (11:59 p.m. EDT) infrared data from the Atmospheric Infrared Sounder aboard NASA's Aqua satellite detected strong thunderstorms completely surrounding the center of Nepartak with temperatures colder than minus 63 degrees Celsius (minus 81 Fahrenheit). Temperatures that cold indicate very powerful thunderstorms with cloud tops high into the troposphere. Bands of powerful thunderstorms wrapped into the low-level center of circulation from the northwest and southeast.NASA scans powerful Typhoon Nepartak

On July 5 at 1500 UTC (11 a.m. EDT) Nepartak's maximum sustained winds were near 120 knots (138 mph/222 kph). Nepartak is currently a category 4 hurricane on the Saffir-Simpson Scale, making it a major hurricane/typhoon. It was centered near 17.6 degrees north latitude and 132.7 degrees east longitude, about 821 nautical miles east-southeast of Taipei, Taiwan. Nepartak is moving to the west-northwest at 18 knots (20.7 mph/33.3 kph). <a href="https://www.earth.com/video/nasa-telescope-will-capture-millions-of-galaxies/">NASA's</a> Aqua satellite passed over Typhoon Nepartak after it became a major typhoon in the Northwestern Pacific Ocean.

The Joint Typhoon Warning Center noted that "passage over very warm water, low vertical wind shear, and favorable outflow enhanced by an upper-level trough to the northwest are supporting the rapid intensification trend."

Nepartak is forecast to move northwest and is expected to intensify to 125 knots (143 mph/231 kph) over the next two days. The Joint Typhoon Warning Center forecast calls for the tropical cyclone to cross over northern and then over far eastern China before reemerging into the Yellow Sea.

First 6 months of 2016 were hottest ever in New Zealand. Ski fields are struggling to open and winter electricity consumption is down in New Zealand after the first six months of 2016 proved to be the hottest start to a year that scientists have ever recorded.
Temperatures in the <a href="https://www.earth.com/image/noumea-in-the-south-pacific-archipelago-of-new-caledonia/">South Pacific</a> nation were 1.4 degrees Celsius (2.5 Fahrenheit) above the long-term average for the first half of the year, according to the government-funded National Institute of Water and Atmospheric Research.
That's the highest since record-keeping began more than a century ago, and significantly higher than the previous record of 1.1 Celsius above average, reached in 1938 and again in 1999. First 6 months of 2016 were hottest ever in New Zealand
Chris Brandolino, a scientist at the research agency, said Monday that ocean temperatures in the Tasman Sea to the west of New Zealand have been unusually warm this year and that warmer winds from the north have also predominated.
"What's happened in the background is that the Earth has continued to warm as greenhouse gas levels have risen," he said.
The agency reported that carbon dioxide levels recorded at a station near Wellington passed 400 parts per million in June for the first time. The threshold is seen as significant internationally as an indicator of climate change.
While many New Zealanders reveled in a summer that never seemed to end, commercial ski fields including Coronet Peak, Mount Hutt and Turoa have found themselves with little snow, electing to delay opening or operating with limited runs as the Southern Hemisphere winter gets underway.
Brandolino said the rise in average temperatures doesn't necessarily mean the ski season will be bad, "although if I'm a skier or snow enthusiast, record warm temperatures aren't going to bode well for me."
Transpower, the government agency which owns the national electricity grid, provided figures to The Associated Press showing that New Zealanders consumed about 2 percent less electricity in June than they did during the same month a year earlier, likely due in part to lower heating requirements.
The Transpower figures showed a June drop of 8 percent in Wellington and 7 percent in Christchurch compared with a year earlier. Those cities are typically cooler in winter than the largest city, Auckland, where the drop was 2 percent.
The June month was the third-hottest June ever recorded in New Zealand and the hottest ever recorded in Christchurch, according to the research agency.

EOMAP: Developing new methods to detect coral bleaching events. The EOMAP aquatic remote sensing company, together with partners at the Remote Sensing Research Centre of Queensland University and the Great Barrier Reef Foundation, are developing new methods to monitor and detect coral bleaching events using Europe’s Sentinel-2A satellite.

The Great Barrier Reef is suffering dramatic levels of coral bleaching over large areas of the northern reefs. EOMAP: Developing new methods to detect coral bleaching events

In order to assess the extent of a bleaching event, scientists and managers often resort to surveys from aircraft, followed by targeted dive surveys. With the <a href="http://www.earth.com/news/brutal-coral-bleaching-event-strikes-the-great-barrier-reef/">Reef</a> being approximately the size of Italy, this is a costly and time-consuming procedure, particularly when repeat surveys are required.

Today, Sentinel-2A provides the required spatial and temporal resolution for detecting and monitoring coral bleaching (of a certain magnitude in area and duration) at Reef-wide scales.

<a href="https://en.wikipedia.org/wiki/NASA">EOMAP</a> and partners believe they have the right algorithms to best exploit these new data sources.

Dr Petra Lundgren, Science Manager at the Great Barrier Reef Foundation, comments, “Given the Great Barrier Reef’s vast size, and the scale of the threats it faces, there is an urgent need to develop new, cost-effective monitoring technologies that will improve the spatial and temporal scope of observation data.”

Australian and German teams are testing this methodology over an area of the Reef where, based on recent aerial surveys, bleaching is occurring. The premise is relatively simple: compare Sentinel-2A images taken before and during coral bleaching.

[caption id="attachment_2401026" align="alignleft" width="150"]<img class="size-thumbnail wp-image-2401026" src="http://cff1.greenatom.net/uploads/2016/07/01174308/coral-bleaching-from-space_1big_sentinel-2_esa-150x150.jpg" alt="An example of the seafloor reflectance product " width="150" height="150" /> An example of the seafloor reflectance product[/caption]

However, such satellite image comparisons are not straightforward, particularly where water-covered targets are concerned. Variations in viewing and illumination geometries, atmospheric conditions, water column optical properties, sea surface roughness, tides and water depth all add to the difficulties.

Dr Magnus Wettle, Managing Director of EOMAP Australia, explains: “These variations, between images taken, say, 1–2 months apart, can distort the measured signal to the point where it significantly affects the perceived differences in the image data; errors of omission and commission are both likely.

“We can get around this by using our proprietary Seafloor Reflectance product.”

Calculated using physics-based algorithms, the EOMAP seafloor reflectance is the theoretical true colour of the seafloor, as if the overlying water column were removed and the viewer were standing on the seafloor.

In other words, the perceived colour of the seafloor is normalised for atmospheric and aquatic optical effects, and seafloor colour can therefore be accurately compared between images taken at different dates, from different sensors, and under varying environmental conditions.

“The areas that are shown in the maps as potentially bleached make sense based on our interpretation of aerial and field observations, as well as our understanding of the coral bleaching process,” says Dr Chris Roelfsema, Co-Director of the Remote Sensing Research Centre at the University of Queensland.

“These results are very promising and will provide a step forward in combining field and satellite methods for monitoring bleaching for large areas such as the Great Barrier Reef.”

The next important step is to incorporate additional, accurate field survey data, acquired over the period during which the corals are bleached, in order to further validate these outputs.

Australian agencies working on the Reef have now collected field survey data, which could be used towards validating this approach.

Once proven, the approach can be deployed across larger, regional scale areas of the Reef, both for mapping and future monitoring purposes.

Hurricane Blas: NASA analyzes first hurricane of the Eastern Pacific season. The second named tropical cyclone of the Eastern Pacific Ocean hurricane season has become hurricane Blas. NASA analyzed Blas in infrared light on July 5 and saw powerful thunderstorms with very cold cloud top temperatures after it reached hurricane status. Earlier, NASA's RapidScat instrument analyzed surface winds as the storm was strengthening from a depression to a tropical storm.

The tropical depression that grew to become Tropical Storm Blas formed at 11 p.m. (0300 UTC) on Saturday, July 2. At that time the center of<a href="https://www.earth.com/news/nasa-catches-tropical-depression-sarika039s-landfall/"> Tropical Depression</a> Three-E was near latitude 11.1 north and longitude 108.3 west. By 5 a.m. EDT on July 3 the depression strengthened into a tropical storm.

On July 3, the RapidScat instrument that flies aboard the International Space Station saw surface winds east of Blas' center near 21 meters per second (46.9 mph/75.6 kph). RapidScat is an important tool for meteorologists, because maximum sustained winds are not always equally distributed in a storm. Hurricane Blas: NASA analyzes first hurricane of the Eastern <a href="https://www.bing.com/search?q=pacific&amp;cvid=48a4b994995f4fb39e182bc8cec44e27&amp;FORM=ANAB01&amp;PC=HCTS">Pacific</a> season shows forecasters the location of the strongest winds in different quadrants of a storm, indicating locations facing greatest impacts.

By July 5, Blas had become the first hurricane of the Eastern Pacific hurricane season. At 5 a.m. EDT (0900 UTC) Maximum sustained winds have increased to near 100 mph (155 kph) with higher gusts.

The center of Hurricane Blas was located near latitude 14.2 North, longitude 118.1 West. That's about 805 miles (1,295 km) southwest of the southern tip of Baja California. Blas is far from land, so there are no coastal watches or warnings in effect.

Blas was moving toward the west-northwest near 14 mph (22 kph), and a motion toward the west-northwest or west is expected for the next couple of days. The estimated minimum central pressure is 978 millibars.

On July 5 at 0941 UTC (5:41 a.m. EDT) infrared data from the Atmospheric Infrared Sounder aboard NASA's Aqua satellite detected strong thunderstorms completely surrounding the center with temperatures colder than minus 75 degrees Celsius (minus 103 Fahrenheit). That indicates very powerful thunderstorms with cloud tops high into the troposphere. Infrared data also suggests a ragged eye has developed.

Visible satellite data shows that the overall convective cloud pattern has also become more symmetrical.

The National Hurricane Center (NHC) said that additional strengthening is expected, and Blas is forecast to become a major hurricane later today, July 5. NHC noted that in two days, Blas will be moving over cooler waters that will put the storm on a weakening trend.

The first named tropical storm of the Eastern <a href="http://www.earth.com/news/pacific-salmon-water-temperatures/">Pacific</a> Hurricane Season formed over the July 4th holiday weekend and by July 6 had weakened to a remnant low pressure area. NASA's Terra satellite captured a visible light image of tropical storm Agatha before the storm's big fireworks finale fizzled.

Agatha, which started out as Tropical Depression 2-E formed Friday, July 1 at 11 p.m. EDT. By 11 a.m. PDT (1500 UTC) on July 2, the depression strengthened into a tropical storm about 775 miles (1,245 km) southwest of the southern tip of Baja California, <a href="https://en.wikipedia.org/wiki/Mexico">Mexico</a>.

As Agatha neared peak intensity, NASA's Terra satellite flew overhead on July 3.The MODIS (Moderate Resolution Imaging Spectroradiometer) instrument aboard NASA's Terra satellite captured a visible image of Agatha on July 3, 2016 when the storm's maximum sustained winds were near 45 mph (75 kph).The image showed strongest thunderstorms on the eastern side of the storm with a band of storms wrapping into the low-level center of circulation from the northwest.

At 11 p.m. EDT (0300 UTC), on July 4, Agatha became a remnant low pressure area. The center of Post-Tropical Cyclone Agatha was located near latitude 19.3 North, longitude 130.4 West. That's about 1,345 miles (2,160 km) west of the southern tip of Baja California, Mexico. The post-tropical cyclone was moving toward the west near 12 mph (19 kph). Maximum sustained winds are near 35 mph (55 kph) and weakening.

By July 5 at 0300 UTC (July 4 at 11 p.m. EDT) Agatha's remnants were located near 19.3 degrees north latitude and 130.4 degrees west longitude. Agatha continued to move west and is expected to dissipate like fading fireworks in a day or two.

Understanding forest fire history can help keep forests healthy. For nearly a century, forest fires have been viewed by scientists and the public as dangerous and environmentally damaging disasters. However, recent research has shown that forest fires are vital to maintaining healthy forests. While people in the western portions of the U.S. experience forest fires often and know of their value, many people on the eastern side of the U.S. do not know of their importance. In a new study, University of <a href="https://en.wikipedia.org/wiki/Missouri">Missouri</a> researchers have studied tree rings throughout <a href="http://www.earth.com/news/explosive-wildfires-western-oklahoma/">Oklahoma</a> and Tennessee to determine the history of fires in those areas.

Michael Stambaugh, assistant research professor in the MU College of Agriculture, Food and Natural Resources, says understanding this history is important for managing and improving the ecology of forests in the future.

"Many forest ecosystems are fire-dependent, meaning that in order to maintain their health and vibrancy, they must be subjected to fire on a regular basis," said Stambaugh, who is a member of the Missouri Tree-Ring Laboratory at MU. "By understanding how fire has maintained forest ecosystems in the past, we can determine the best ways to use fire to maintain those forests in the future."

To study the history of fire in Oklahoma and Tennessee, Stambaugh examined tree rings from 332 trees in eight different sites throughout both states. Stambaugh found 843 different fire scars embedded within the tree rings and was able to determine when and how often each site experienced forest fires over the last 300 years. He found that despite having a wetter, cooler climate, forests in Tennessee experienced higher fire frequency than Oklahoma. He also found that fires existed in those areas long before Euro-American settlement, showing that fire has been important to those forests for centuries.

"The history of fire in America also is the history of humans on this continent," Stambaugh said. "Humans have been here for more than 12,000 years and everywhere we see humans move, we see fires follow or be altered. This has been a constant for so long that forest ecology has become dependent on these fires, if they already weren't before humans arrived. However, many parts of the U.S., especially in the eastern half of the continent, have not experienced forest fires in more than 150 years because humans have worked hard to prevent those fires. Many of those forests are now suffering because of the lack of fire to help renew the ecology."

In order to understand the effects of fire around the U.S., Stambaugh and his fellow MU researchers are cataloging the history of fire by studying tree rings from trees throughout the entire country.
###
The study, "Scale Dependence of Oak Woodland Historical Fire Intervals: Contrasting the Barrens of Tennessee and Cross Timbers of Oklahoma, USA," was published in Fire Ecology. The study was coauthored by MU Associate Professor Richard Guyette along with Joseph Marschall and Daniel Dey of the USDA Forest Service Northern Research Station located at MU.

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

Satellites reveal how Earth's systems are interconnected

[sendtonews key="JbW4VsY53O-1632195-12187" type="single"] Satellites reveal how Earth's systems are interconnected...

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.

Today's Video of the Day from the <a href="http://www.esa.int/">European Space Agency</a> features Qeshm Island in the Strait of Hormuz. This strait provides the only sea passage from the Persian Gulf to the open ocean.



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.
