Melting glaciers may be silently setting the stage for more explosive and frequent volcanic eruptions in the future, according to research on six volcanoes in the Chilean Andes.
Presented today (July 8) at the Goldschmidt Conference in Prague, the study suggests that hundreds of dormant subglacial volcanoes worldwide – particularly in Antarctica – could become more active as climate change accelerates glacier retreat.
The link between retreating glaciers and increased volcanic activity has been known in Iceland since the 1970s, but this is one of the first studies to explore the phenomenon in continental volcanic systems. The findings could help scientists better understand and predict volcanic activity in glacier-covered regions.
Researchers from the University of Wisconsin-Madison, USA, used argon dating and crystal analysis across six volcanoes in southern Chile, including the now dormant Mocho-Choshuenco volcano, to investigate how the Patagonian Ice Sheet’s advance and retreat influenced past volcanic behaviour. The work is in collaboration with researchers from Lehigh University, University of California Los Angeles, and Dickinson College.
By precisely dating previous eruptions and analysing crystals in erupted rocks, the team tracked how the weight and pressure of glacial ice alter the characteristics of magma underground.
They found that during the peak of the last ice age (around 26,000-18,000 years ago), thick ice cover suppressed the volume of eruptions and allowed a large reservoir of silica-rich magma to accumulate 10-15 km below the surface.
As the ice sheet melted rapidly at the end of the last ice age, the sudden loss of weight caused the crust to relax and gasses in the magma to expand. This buildup of pressure triggered explosive volcanic eruptions from the deep reservoir, causing the volcano to form.
Pablo Moreno-Yaeger from the University of Wisconsin-Madison, USA, is presenting the research at the Goldschmidt Conference. He said: “Glaciers tend to suppress the volume of eruptions from the volcanoes beneath them. But as glaciers retreat due to climate change, our findings suggest these volcanoes go on to erupt more frequently and more explosively. The key requirement for increased explosivity is initially having a very thick glacial coverage over a magma chamber, and the trigger point is when these glaciers start to retreat, releasing pressure – which is currently happening in places like Antarctica.
“Our study suggests this phenomenon isn’t limited to Iceland, where increased volcanicity has been observed, but could also occur in Antarctica. Other continental regions, like parts of North America, New Zealand and Russia, also now warrant closer scientific attention.”
While the volcanic response to glacial melting is almost instant in geological terms, the process of changes in the magma system is gradual and occurs over centuries, giving some time for monitoring and early warning.
The researchers also note that increased volcanic activity could have global climate impacts. In the short term, eruptions release aerosol (tiny particles in gases) that can temporarily cool the planet. This was seen after the 1991 eruption of Mount Pinatubo in the Philippines, which reduced global temperatures by approximately 0.5 degrees C. But with multiple eruptions, the effects reverse.
“Over time the cumulative effect of multiple eruptions can contribute to long-term global warming because of a buildup of greenhouse gases,” said Moreno-Yaeger. “This creates a positive feedback loop, where melting glaciers trigger eruptions, and the eruptions in turn could contribute to further warming and melting.”
The research was funded by the National Science Foundation as part of a grant led by Professor Brad Singer at UW-Madison, and is due to be published in a peer-reviewed journal later this year.
The Goldschmidt Conference is the world’s foremost geochemistry conference. It is a joint congress of the European Association of Geochemistry and the Geochemical Society (US), and over 4000 delegates attend. It takes place in Prague, Czech Republic, from July 6-11 2025.
In the days before Hurricane Milton hit Florida, forecasters worried it could send as much as 15 feet of water rushing onto the heavily populated shores of Tampa Bay

In the days before Hurricane Milton hit Florida, forecasters were worried it could send as much as 15 feet (4.5 meters) of water rushing onto the heavily populated shores of Tampa Bay.
Instead, several feet of water temporarily drained away.
Why? “Reverse storm surge” is a familiar, if sometimes unremarked-upon, function of how hurricane winds move seawater as the storms hit land — in fact, it has happened in Tampa Bay before.
In the Northern Hemisphere, tropical storm winds blow counterclockwise. At landfall, the spinning wind pushes water onshore on one end of the eye and offshore on the other. Picture drawing a circle that crosses a line, and see how the pencil moves toward the line at one point and away at another.
The most pronounced water movement is under the strong winds of the eyewall, explains Brian McNoldy, a University of Miami senior researcher on tropical storms.
Milton’s path toward the central part of Florida’s west coast was clear for days, raising the possibility that Tampa Bay could bear the brunt of the surge. But it is always tricky to predict exactly where landfall will happen — and when, which can be important because a daily high tide can accentuate a surge.
To be sure, hazardous wind, rain and some degree of surge can happen far from the center. But the exact location of landfall makes a big difference in where a surge peaks, McNoldy said. Same goes for a reverse, or “negative,” surge.
Ultimately, the center of east-northeastward-moving Milton made landfall Wednesday night at Siesta Key, near Sarasota. It is about 70 miles (112 kilometers) south of the city of Tampa.
That meant fierce onshore winds caused a storm surge south of Siesta Key. The National Hurricane Center said Thursday that preliminary data shows water rose 5 to 10 feet (1.5 to 3 meters) above ground between Siesta Key and Fort Myers Beach.
More than 19 million Americans may be exposed to unsafe drinking water, researchers warn.
Millions of Americans may be exposed to contaminated drinking water systems that are dangerous for their health, an updated interactive map shows.
The map, a collaborative effort by Environmental Working Group, a nonprofit, nonpartisan organization, and Northeastern University‘s Social Science Environmental Health Research Institute, documents toxic fluorinated compounds known as PFAS at publicly known pollution sites across the U.S., including public water systems, military bases, military and civilian airports, industrial plants, dumps and firefighter training sites.
The researchers found at least 610 drinking water sources in 43 states contain potentially unsafe PFAS levels, and estimate that more than 19 million people are exposed to these man-made chemicals that have been linked to birth defects, increased risk of thyroid disease, infertility and reduced immune responses in children.
“The Environmental Protection Agency has utterly failed to address PFAS with the seriousness this crisis demands, leaving local communities and states to grapple with a complex problem rooted in the failure of the federal chemical regulatory system,” said Ken Cook, president of Environmental Working Group, in a press release. “EPA must move swiftly to set a truly health-protective legal limit for all PFAS chemicals, requiring utilities to clean up contaminated water supplies.”
Any detection of these chemicals were included in the interactive map, despite some of the levels being well below the Environmental Protection Agency’s “non-binding health advisory” standard of 70 parts per trillion, said Bill Walker, editor-in-chief of the Environmental Working Group, via email.
“We, along with many states and academic scientists, regard that number as far too high,” said Walker, who wrote the map’s accompanying reportlet. “EWG endorses studies by Dr. Phillipe Grandjean of Harvard that say levels as low as 1 (part per trillion) could have adverse health effects such as repressed immune function in children. Therefore, we believe a map showing only detections above the EPA advisory would be misleading as to the true extent of the contamination crisis.”
However, a spokesperson for the Environmental Protection Agency cautions the map “seems to show any samples for PFAS chemicals that have been collected, which may or may not be detections.”
“EPA has not fully reviewed the quality of the underlying data, and based on the agency’s commitment to good risk communication with the public, EPA cannot recommend the map be used to determine where public health risks associated with PFAS chemicals may or may not exist,” John Konkus, the EPA’s deputy associate administrator for public affairs, wrote in an email. “The agency’s efforts continue to be focused on taking the actions committed to in the PFAS Action Plan.”
Michigan has 192 sites on the map, reflecting the most comprehensive testing program in the U.S., according to the press release, followed by California, at 47, and New Jersey, at 43. The map also documents 117 military sites.
“Leaders in many communities and states are doing great work to raise awareness about PFAS and push for cleanup, but this is a national crisis demanding national action,” Phil Brown, director of the Social Science Environmental Health Research Institute, said in a press release. “The EPA should act more quickly to evaluate all PFAS chemicals and restrict their use, and polluting industries should be held responsible.”
In March, a bipartisan pair of PFAS-monitoring bills were introduced in U.S. Congress to “inform and enhance assessments of exposure, likely health and environmental impacts, and remediation priorities,” according to the House version of the bill. Meanwhile, the Centers for Disease Control and Prevention and Agency for Toxic Substances and Disease Registry are calling for researchers to apply for a multi-site project on the human health effects of PFAS exposure.

HUMAITA, Brazil (Reuters) – Water levels in the rivers that run through the vast Amazon rainforest have been falling, after a record drought followed by less rain, presenting unprecedented challenges for the Ribeirinhos people living there.
Generative AI Too Disruptive for Its Own Good: DeepAI FounderPlay Video
With rivers becoming more difficult to navigate and water too dirty to consume, many of the traditional rural population who live on river banks have been relying on outside supplies of drinking water.
Francisca das Chagas da Silva, a resident, said older people in particular have struggled because they needed to walk much further to get water. “We have to carry it from the riverbanks to our homes,” she said.
The Ribeirinhos usually get water directly from rivers or have connected systems – but these means of supply fail when water levels drop so dramatically.
Now, many residents rely on non-governmental organizations or the state government for drinking water.
Joao Ferreira Mendonca, a community leader, said the river bank was about 800 meters (0.5 miles) away from some homes, a long distance for an older person or one with health problems.
“Now imagine a person in the hot sun, people with high blood pressure, doing this journey,” he said.
The Brazilian Geological Service, SGB, has warned in recent days that all rivers in the Amazon basin were expected to drop below their historical levels.
Ribeirinhos usually live on river banks in pile dwellings – from where they move with motor boats.
Rosicleia Gomes Vieira, another resident, said life in general was becoming much more isolated because the low water levels make navigation more difficult and impossible to carry produce to the city.
Other than the rivers, which have long been the main way of transport for residents, there is only a long dirt road that cuts through the dense rainforest.
In Brazil, where wildfires have also occurred, the low water levels are also hitting soy and corn shipments in center-west states such as Mato Grosso, Brazil’s number one grains growing area.

A study of chemicals in U.S. drinking water found that arsenic, even in small concentrations, is responsible for disproportionate numbers of cancer cases.
Chemicals present within legal limits in tap water are projected to be responsible for more than 100,000 cancer cases in the U.S., according to estimates from a new study.
The study, published Thursday in the journal Heliyon, looked at nearly 50,000 water systems across the country. It analyzed the presence of 22 cancer-causing chemicals that are regulated by states and the Environmental Protection Agency but still found in varying degrees in drinking water.
Researchers with the Environmental Working Group, a nonprofit advocacy organization, said the study is the first to project on a national level the cancer risk the combination of chemicals pose over a person’s statistical lifetime – about 70 years.
They found that the majority of cancer cases came from water systems that were fully complying with drinking water standards set either by states or the EPA.
“Water that meets legal standards still poses health risks,” says Sydney Evans, the lead author of the study and a science analyst at Environmental Working Group.
Of the nearly two dozen chemicals examined, the biggest problem is arsenic, which even in small concentrations is responsible for disproportionate numbers of cancer cases, according to the study. But Evans says that this study is an attempt to start looking at the chemicals present in water as a mixture instead of assessing them one by one.
The analysis is conservative, according to Evans, because it only looked at chemicals with national monitoring data or health benchmark levels. Many more chemicals exist in drinking water that haven’t been studied enough to include in the assessment, Evans says.
The study does not include measurements from private wells, which roughly 13.5 million Americans rely on for drinking water. Private wells don’t have to follow federal drinking water standards.
A water filter is a good “first course of action for an individual who is concerned,” Evans says. Residents should check their local water reports to know what kind of filter would be best for the types of chemicals present where they live.
The study shows that tougher standards for drinking water are needed, according to Evans.
“Filters aren’t a solution,” Evans says. “They’re a measure people can take right now until their water quality is improved.”
Satellite imagery of Chennai that circulated across the internet in June starkly demonstrates how drought is affecting the Indian city. The pictures show how the reserves that provide the city with most of its water are nearly dry, contributing to a water scarcity crisis that has hit the 7 million residents hard.
The images from Chennai highlight how water scarcity is reaching into a growing number of countries. An estimated 600 million people across India face high to extreme water stress, according to a 2018 report by NITI Aayog, a think tank affiliated with the government. More than 2 billion people in 53 countries are experiencing high water stress, according to a report from the United Nations released earlier this year.
To combat these crises, many countries are taking measures to conserve water and find solutions to ongoing droughts. And while many of the measures are conventional strategies, from restricting public consumption of water to fixing faulty pipe systems, some of the solutions that have been proposed or implemented have been more creative. Here are five unusual solutions to global water shortages.

The 2017-18 water shortage in Cape Town, South Africa was one of the worst in recent memory, attracting international attention as people tried to find solutions to the crisis before the city would be forced to shut down its water taps. One idea that was considered by experts was the unusual plan to tow an iceberg from Antarctica across 2,500 miles as a new freshwater source for the struggling region, according to Bloomberg.
Nick Sloane, an expert in marine salvage, came up with the idea, and although the crisis was ultimately averted, concerns about South Africa’s water supply remain and he is still planning to carry out the idea. The project, which is estimated to cost more than $200 million, would use two tugboats to encircle an iceberg in a net fashioned with the supermaterial dyneema. The iceberg would then be towed by tankers to South Africa’s western coast, where it would be harvested for fresh drinking water. Sloane is currently working on developing a deal with South Africa to sell the water to them.

Nearly a tenth of the nation’s drinking water service lines contain lead, new data shows.
TNS
A piece of old lead pipe is seen in 2016 in Chicago.
In a first-of-its-kind report, the Environmental Protection Agency has released a comprehensive assessment on lead pipe infrastructure across the United States, revealing that an estimated total of 9.2 million lead pipes serviced American homes in 2021.
According to the report, lead service lines are estimated to make up over 9% of the entire national service line infrastructure, exposing much of America’s drinking water to lead contamination.
The EPA says there are no safe levels of lead in children’s blood, as lead exposure has been tied to an array of adverse health effects in children, including behavioral problems, lower IQ and slowed growth. In adults, lead exposure is linked with decreased cardiovascular health and kidney function, and lead exposure in pregnant women is linked to premature births.
The bulk of the nation’s lead pipe infrastructure is concentrated in a handful of states, including many of the Rust Belt states in the Great Lakes region. Florida has the most lead service lines in the country, with its 1.16 million lines accounting for 12.6% of the country’s total. Over 50% of the national service lines are concentrated in six states: Florida, Illinois (11.4%), Ohio (8.1%), Pennsylvania (7.5%), Texas (7.1%) and New York (5.4%).
Lead service lines are far less common west of the Mississippi River, with Texas as the lone exception. Notably, California’s service line infrastructure, which serves the largest state population over the third-largest area, has less than 13,500 lead service lines, or about 0.15% of the national total.
Federal law prohibits installing new lead plumbing because of its dangers to health. In 2021, the Biden Administration announced an aggressive plan to replace all lead service lines in the next decade as part of the Bipartisan Infrastructure Law, and earlier this year the EPA announced that $1.2 billion had already been distributed to 23 states to address that goal. But the costs associated with such an effort are significant. Over the next two decades, the EPA report estimates that $625 billion is needed to address the challenges with drinking water infrastructure.
Lead exposure does not impact all American demographics evenly. The Centers for Disease Control and Prevention published a study in 2021 indicating that non-Hispanic Black or African American children were at particular risk, as well as children living in areas with higher poverty rates.
Although the Safe Drinking Water Act, which was enacted 1974 and amended most recently in 1996, aims to ensure the public’s access to contaminant-free water, large-scale issues with drinking water distribution systems are still prevalent. Spikes in the rates of lead in children’s blood in 2015 sparked the start of a years-long water crisis in Flint, Michigan. The city of Jackson, Mississippi, which endured days with a full water outage last August and September, has ongoing projects to reduce elevated levels of lead in its water supply, and lead contamination has led to crises in Newark, New Jersey, Chicago and Washington, D.C., among other communities.
These are the states with the most lead pipes, according to the EPA:

HAVANA (Reuters) – Water shortages in Cuba are increasingly flaring tempers, including in capital Havana, as problems mount for hundreds of thousands of residents already ragged from shortfalls in food, fuel and electricity.
Upwards of 600,000 people – more than 1 in 20 on the Caribbean island of 10 million citizens – are suffering from water supply issues, officials said earlier this month.
Havana is the worst affected by water shortages, though most of the country’s largest cities report over 30,000 customers without water, the government has said.
Officials blame the growing problems on crumbling infrastructure and a persistent lack of fuel, symptoms of a festering economic crisis that has blighted growth and left the Communist-run country nearly bankrupt.
Rachel Trimiño, 32, said the root causes are no mystery, even in her Havana neighborhood of Vedado, a comparatively upscale district of the capital.
“All of the streets are full of leaking pipes, clean running water … but nothing in our homes,” she said.
The problem defies quick fixes.
Spare parts for outdated water infrastructure, like pipes and pumps, are in short supply, officials said. And without fuel and adequate transportation, even emergency water supply by cistern truck has been limited, according to residents.
Frequent blackouts only make matters worse.
“When they cut off power, we can’t give water,” said San Miguel de Padron resident Pedro Martino, who works with a church group that offers residents small quantities to stem the shortfall. “One thing depends on the other, and that’s the game we play.”
Isolated protests have erupted in some areas, as residents overwhelmed by the growing list of problems and shortages lose patience in the still blistering heat of the tropical summer.
Cuba’s economy has been decimated by a combination of factors, including the COVID-19 pandemic, stiffened U.S. sanctions and a state-dominated business model plagued by bureaucracy, mismanagement and corruption.
The social and economic crisis is widely seen as among the worst since Fidel Castro’s 1959 revolution, leading to a record-breaking exodus of Cuban migrants in the past two years.

California’s water supply for this year looks promising, with the statewide Sierra Nevada snowpack standing at its tallest in four years for early January, according to the state’s Department of Water Resources latest measurement on Thursday.
The Sierra Nevada mountain range supplies nearly a third of California’s water supply as it melts and sends billions of gallons of water into the state’s rivers, according to The Mercury News. On Thursday, state officials conducted their first snowpack measurement of the season at Phillips Station near Lake Tahoe and determined that the snow was 33.5 inches deep and its water content was 97% of the historical average for this time of year.
“It’s a good start,” Chris Orrock, a spokesman for the state Department of Water Resources, told The Mercury News. “It’s better than it was last year. But it’s still early. We’re cautiously optimistic.”
Now, the state must wait to see if January and February, which account for a large portion of California’s precipitation, will be as fruitful as was December.
In early December, rains reduced the portion of the state considered to be abnormally dry from 85.3% to 3.6% in just a week.
“It’s still too early to predict what the remainder of the year will bring in terms of snowpack,” Sean de Guzman, chief of the agency’s snow surveys and water supply forecasting area, told the Los Angeles Times.
After California’s historic drought of 2012 to 2016, the state also has some policies in place to help preserve the water supply. Due to legislation signed by then-Gov. Jerry Brown, officials in areas with some of the most over-pumped groundwater basins must tell the state this month how they will replenish their supplies. There are also a number of dam projects in the works, including one to raise the height of the Los Vaqueros Reservoir.
What’s the difference between Alkaline Water and Ionized Alkaline Water?
Water that has a pH higher than 7.0 is considered Alkaline Water. Minerals, such as baking soda, or other chemicals can be added to water to alter the water’s pH. This process is often confused as meaning Ionized Alkaline Water; however, they are entirely different.
Alkaline Water Ionizers are what create the Ionized Alkaline Water that we’ve come to enjoy. Ionized Alkaline Water is created during the electrolysis process, which gets rid of the low-quality water rather than altering it.
Quick Answer: Water that has a pH higher than 7.0 is Alkaline Water. Generally, this is created with chemicals, minerals and buffers, which lack the antioxidants needed to truly heal.

Here’s why Ionized Alkaline water is better than Bottled Alkaline Water
Alkaline Ionized Water (from a water ionizer machine) and Bottled Water are different because:
Additives, Chemicals, and pH buffers are often used to create a positive ORP Value. By creating Alkaline drinking water with our Water Ionizers, you’ll be drinking chemical free, natural water
With ZERO antioxidant value and a positive ORP value, Bottled Water lacks any molecular hydrogen.
Ranging from $2 to $5 per liter, bottled water is vastly more expensive compared to less than a penny per liter with our Water Ionizer, which will also generate nearly limitless amounts of Alkaline Ionized Water.
Alkaline Water Ionizers, such as our Aqua Ionizer Deluxe 9.5, also provide the benefit of less waste materials, effectively creating a smaller carbon footprint. Bottled water is expensive due to transportation costs, and materials. They also create more waste since they’re only used once then thrown away, making it a very short life-cycled product and wasteful.
What is Positive ORP and Negative ORP?
Liquids, such as Soda, Water, Green Tea, and Coffee, all have an ORP, which is the measure of oxidation reduction point.
Antioxidants have a Negative (-) ORP measurement, thus helping eliminate free radicals and help repair the body.
Quick Answer: ORP is the measure of Oxidation Reduction Potential of a substance.
ORP Measures Antioxidants, and Antioxidants HELP YOU HEAL!
Green Tea has a -ORP of 120mV, meaning it is high in antioxidants.
Opposite of the -ORP is the positive ORP. This positive ORP creates excessive oxidation, and free radicals in your body. Most carbonated beverages, such as soda (acidic) have a positive ORP.
Interestingly, most bottled water will contribute to oxidation since it has a positive ORP.
Ionized water is recommended to be consumed immediately after it’s been produced, due to Negative ORP being highly reactive and dynamic. It will also return to it’s neutral or positive state over the course of a few days- demonstrated by it “going flat.”
When ionized water is sitting around for a few days, you’ll begin to see the “off gassing” effect on the water container, where bubbles start to collect on the container. Negative ORP will drop with the increase of apparent bubbles being “off gassed.”
Our Aqua Ionizer Deluxe 7.0™ creates a -ORP of up to 800, a high antioxidant rich solution, depending on the water source. Consuming this water immediately after it’s produced by the water ionizer machine, will ensure that you’re receiving a substantially high oxidation reduction potential (ORP) water.
Our Aqua Ionizer Deluxe 9.0™ creates a -ORP of 860, which is approaching the high end of the spectrum. This unit features the “Daily Drinking” setting, which will allow you to enjoy a -ORP of 300. Comparing that to a cup a green tea, water created from our Water Ionizer machine will ensure you’re receiving more than 3 times the antioxidants!
Alkaline Water Benefits
Health Benefits of Alkaline Water
Toxic substances find their way into our bodies, and Alkaline Water can help combat and counteract that by helping neutralize the acid in our bodies. In an Alkaline environment, your body can focus on healing and fighting back against those toxic substances.
Acidic water can help rehydrate skin and can act as an astringent to help prevent skin problems such as acne, wrinkles, and other skin problems. Acidic water is also great for cleaning glass, and other surfaces in your kitchen. Most plants and flowers also thrive with a lower pH water and actually prefer this environment over a higher pH water.
Antioxidants are created simultaneously while both high and low pH waters are being produced. Molecular hydrogen, antioxidants, and oxygen allow the body to recover and heal effectively and efficiently. Molecular hydrogen helps combat free radicals in the body and helps boost your immune system by working deep within the cell walls.
