‘The precedent is Flint’: How Oregon’s data center boom is supercharging a water crisis

‘The precedent is Flint’: How Oregon’s data center boom is supercharging a water crisis

Rolling Stone reports: In the spring of 2022, Jim Doherty kept having the same conversation with folks at the only grocery store in Boardman, his eastern Oregon hometown, or at the grain depot where he picked up food for his four ranch dogs. Healthy adults that these people knew were coming down with unexplained medical conditions, including diseases and cancers that usually afflicted the elderly. “It was kinda grim,” Doherty says. Sixty years old, broad-chested, with a salt-and-pepper goatee, Doherty…

Nature can bounce back if we just give it a chance

Nature can bounce back if we just give it a chance

Emma Marris writes: When the last of four dams on the Klamath River in southern Oregon and Northern California was demolished in October 2024, everyone who knew the river well had a question: How long would it take for salmon to reclaim the upper reaches they’d been cut off from for more than 100 years? About 10 months later, when they began their fall migration, Chinook salmon immediately took advantage of their new river access, looking for places upstream to…

How humanity has broken a cycle that sustains life on Earth

How humanity has broken a cycle that sustains life on Earth

Jack Lohmann writes: Stored in rock and organic material, phosphorus cycles slowly around Earth, through magma and mountains, down rivers, through waste and into oceans. Without it, there’d be no life – every living being needs it to grow. Unlike other mined materials, we all eat it. In the human body, it gives our cells energy, structure and identity, and it is particularly concentrated in our bones. Rare enough to be notable, common enough to be necessary, phosphorus tracks the…

Thousands of toxic sites across America at risk of coastal flooding

Thousands of toxic sites across America at risk of coastal flooding

The Guardian reports: More than 5,500 toxic sites nationwide could face coastal flooding by 2100 due to rising sea levels, according to new research. The study, published on Thursday in Nature Communications and led by scientists at the University of California, warns that if heat-trapping pollution continues unabated, rising seas will flood a wide range of hazardous facilities including those handling sewage, toxic waste, oil and gas, as well as other industrial pollutants. The analysis relies on projections of a…

Northern Hemisphere absorbing more sunlight than Southern, and clouds can no longer keep the balance

Northern Hemisphere absorbing more sunlight than Southern, and clouds can no longer keep the balance

Live Science reports: Years ago, scientists noted something odd: Earth’s Northern and Southern Hemispheres reflect nearly the same amount of sunlight back into space. The reason why this symmetry is odd is because the Northern Hemisphere has more land, cities, pollution, and industrial aerosols. All those things should lead to a higher albedo — more sunlight reflected than absorbed. The Southern Hemisphere is mostly ocean, which is darker and absorbs more sunlight. New satellite data, however, suggest that symmetry is…

Humans have an internal lunar clock – but light pollution is disrupting it

Humans have an internal lunar clock – but light pollution is disrupting it

Flash Vector/Shutterstock By Stefano Arlaud, Queen Mary University of London Most animals, including humans, carry an internal lunar clock, tuned to the 29.5-day rhythm of the Moon. It guides sleep, reproduction and migration of many species. But in the age of artificial light, that ancient signal is fading – washed out by the glow of cities, screens and satellites. Just as the circadian rhythm keeps time with the 24-hour rotation of the Earth, many organisms also track the slower rhythm…

How soon will the global sea-level rise?

How soon will the global sea-level rise?

Evan Howell writes: In May 2014, NASA announced at a press conference that a portion of the West Antarctic Ice Sheet appeared to have reached a point of irreversible retreat. Glaciers flowing toward the sea at the periphery of the 2-kilometer-thick sheet of ice were losing ice faster than snowfall could replenish them, causing their edges to recede inland. With that, the question was no longer whether the West Antarctic Ice Sheet would disappear, but when. When those glaciers go,…

Coral collapse signals Earth’s first climate tipping point

Coral collapse signals Earth’s first climate tipping point

Science News reports: Earth has entered a grim new climate reality. The planet has officially passed its first climate tipping point. Relentlessly rising heat in the oceans has now pushed corals around the world past their limit, causing an unprecedented die-off of global reefs and threatening the livelihoods of nearly a billion people, scientists say in a new report published October 13. Even under the most optimistic future warming scenario — one in which global warming does not exceed 1.5…

Only 1% of people are eating a healthy and sustainable diet, major report finds

Only 1% of people are eating a healthy and sustainable diet, major report finds

BBC Science Focus reports: A major report on the global food system has found that less than 1 per cent of the world is eating a diet that’s good for the planet and human health. But switching to a healthier eating pattern could prevent up to 15 million premature deaths per year, while cutting global greenhouse gas emissions by up to 20 per cent. These are the findings of a report by the 2025 EAT-Lancet Commission. The report brings together…

Marine mammals are dying in record numbers along the California coast

Marine mammals are dying in record numbers along the California coast

The Los Angeles Times reports: On a spit of sand 12 miles north of Santa Cruz, a small, emaciated sea lion lay on its side. The only sign of life was the deep press of its flippers against its belly, relaxing for a few seconds, then squeezing again. “That’s a classic sign of lepto,” said Giancarlo Rulli, a volunteer and spokesperson with the Marine Mammal Center, pointing to the young animal’s wretched self-embrace. The corkscrew-shaped bacteria, leptospirosis, causes severe abdominal…

Jane Goodall (1934–2025): primatologist, conservationist, and messenger of hope

Jane Goodall (1934–2025): primatologist, conservationist, and messenger of hope

Rhett Ayers Butler writes: Jane Goodall, who revealed the intimate lives of chimpanzees and gave the modern world a language of hope, has died at the age of 91. Over the course of six decades, she moved from an unlikely young researcher in the forests of East Africa to one of the most recognizable scientists and conservationists of her time. Her patient fieldwork at Gombe transformed primatology, overturning entrenched beliefs about the uniqueness of humans and forcing science to reckon…

A massive eruption 74,000 years ago affected the whole planet – archaeologists use volcanic glass to figure out how people survived

A massive eruption 74,000 years ago affected the whole planet – archaeologists use volcanic glass to figure out how people survived

Collecting microscopic glass samples at Border Cave in the Lebombo Mountains in South Africa. Katherine Elmes By Jayde N. Hirniak, Arizona State University If you were lucky 74,000 years ago, you would have survived the Toba supereruption, one of the largest catastrophic events that Earth has seen in the past 2.5 million years. While the volcano is located in what’s now Indonesia, living organisms across the entire globe were potentially affected. As an archaeologist who specializes in studying volcanic eruptions…

The surprising recovery of once-rare birds

The surprising recovery of once-rare birds

Sandhill cranes can be spotted in many states, but in the 1930s their populations had crashed to a few dozen breeding pairs in the eastern U.S. Rsocol/Wikimedia Commons, CC BY By Tom Langen, Clarkson University When I started bird-watching as a teenager, a few years after the first Earth Day in 1970, several species that once thrived in my region were nowhere to be found. Some, like the passenger pigeon, were extinct. Others had retreated to more remote, wild areas…

Scientists transform plastic waste into efficient carbon dioxide capture materials

University of Copenhagen: Chemists at the University of Copenhagen have developed a method to convert plastic waste into a climate solution for efficient and sustainable CO2 capture. This is killing two birds with one stone as they address two of the world’s biggest challenges: plastic pollution and the climate crisis. The work is published in the journal Science Advances. As CO2 concentrations in the atmosphere keep rising regardless of years of political intentions to limit emissions, the world’s oceans are…

How many AI queries does it take to use up a regular plastic water bottle’s worth of water? kieferpix/iStock/Getty Images Plus By Leo S. Lo, University of Virginia Artificial intelligence systems are thirsty, consuming as much as 500 milliliters of water – a single-serving water bottle – for each short conversation a user has with the GPT-3 version of OpenAI’s ChatGPT system. They use roughly the same amount of water to draft a 100-word email message. That figure includes the…

Collapse of critical Atlantic current is more likely than previously thought, study finds

Collapse of critical Atlantic current is more likely than previously thought, study finds

The Guardian reports: The collapse of a critical Atlantic current can no longer be considered a low-likelihood event, a study has concluded, making deep cuts to fossil fuel emissions even more urgent to avoid the catastrophic impact. The Atlantic meridional overturning circulation (Amoc) is a major part of the global climate system. It brings sun-warmed tropical water to Europe and the Arctic, where it cools and sinks to form a deep return current. The Amoc was already known to be…
