Trump issued an executive order Thursday declaring that U.S. policy includes “creating a robust domestic supply chain for critical minerals derived from seabed resources to support economic growth, reindustrialization, and military preparedness.” He described seabed mining as both an economic and national security imperative necessary to counter China.

Increasingly, mining companies have been eager to scrape the ocean floor for cobalt, manganese, nickel and other metals that could help make batteries for cellphones and electric cars. But scientists have warned that the process could irreparably alter the seabed, kill extremely rare sea creatures that haven’t been named or studied, and — depending on how the metals are carried up to the surface — risk introducing metals into fisheries that many Pacific peoples rely upon.

The order aims to jump-start the industry that has been spearheaded by small Pacific nations like Nauru seeking economic growth, but has been facing growing pushbac

Trump officials are analyzing whether to remove federal protections for national monuments spanning millions of acres in the West, according to two people familiar with the matter and an internal Interior Department document, in order to spur energy development on public lands.

Interior Department aides are looking at whether to scale back at least six national monuments, said these individuals, who spoke on the condition of anonymity because no final decisions had been made. The list, they added, includes Baaj Nwaavjo I’tah Kukveni-Ancestral Footprints of the Grand Canyon, Ironwood Forest, Chuckwalla, Organ Mountains-Desert Peaks, Bears Ears and Grand Staircase-Escalante — national monuments spread across Arizona, California, New Mexico and Utah.

Interior Department officials are poring over geological maps to analyze the monuments’ potential for mining and oil production and assess whether to revise their boundaries, one individual said.

At least 156 million Americans, about 46 percent of the population, live with unsafe levels of ozone, particulate pollution or both, according to the American Lung Association’s annual State of the Air report.

Air quality in the United States has been generally improving since the Clean Air Act was enacted in 1970, with levels of key pollutants dropping by nearly 80 percent. But millions of Americans still breathe polluted air every day, leading to both acute and chronic health conditions that, in some cases, increase the risk of early death.

Plans by the Trump administration to loosen environmental regulations and cut funding for air quality research would make matters worse, the report says.

“The biggest thing that has saved patients’ lives in regard to lung health and overall health is the Clean Air Act,” said Panagis Galiatsatos, a pulmonologist at the Johns Hopkins School of Medicine and spokesman for the lung association. “Clearly, legislation is needed because that’s what dic

In the summer of 1982, seven heroin users were admitted to a California hospital paralyzed and mute. They were in their 20s, otherwise healthy — until a synthetic drug they had manufactured in makeshift labs left them frozen inside their own bodies. Doctors quickly discovered the cause: MPTP, a neurotoxic contaminant that had destroyed a small but critical part of the brain, the substantia nigra, which controls movement.

The patients had developed symptoms of late-stage Parkinson’s, almost overnight.

The cases shocked neurologists. Until then, Parkinson’s was thought to be a disease of aging, its origins slow and mysterious. But here was proof that a single chemical could reproduce the same devastating outcome. And more disturbing still: MPTP turned out to be chemically similar to paraquat, a widely used weedkiller that, for decades, had been sprayed on farms across the United States and Europe.

For a young Dutch doctor named Bas Bloem, the story would become formative. In 1989, sho

For decades, farmers across America have been encouraged by the federal government to spread municipal sewage on millions of acres of farmland as fertilizer. It was rich in nutrients, and it helped keep the sludge out of landfills.

But a growing body of research shows that this black sludge, made from the sewage that flows from homes and factories, can contain heavy concentrations of chemicals thought to increase the risk of certain types of cancer and to cause birth defects and developmental delays in children.

Known as “forever chemicals” because of their longevity, these toxic contaminants are now being detected, sometimes at high levels, on farmland across the country, including in Texas, Maine, Michigan, New York and Tennessee. In some cases the chemicals are suspected of sickening or killing livestock and are turning up in produce. Farmers are beginning to fear for their own health.

The national scale of farmland contamination by these chemicals — which are used in everything

The protected land includes a one-acre fish hatchery at Unicorn Lake in eastern Maryland and the sprawling Green Ridge State Forest in the west. It includes shorelines, farms and woods around Naval Air Station Patuxent River, and the Chesapeake Forest Lands, some 75,000 wooded acres that are home to species like bald eagles and the once-endangered Delmarva fox squirrel.

None of it can be developed, and all of it has helped Maryland reach a landmark conservation goal six years ahead of schedule, before any other state that’s joined an effort known as “30 by 30.”

The program is part of a global initiative to protect 30 percent of the Earth’s land and waters by 2030. In 2023, Maryland joined the effort and a year later, Gov. Wes Moore, a Democrat, announced that the goal had already been met. Nearly 1.9 million acres of land has been permanently protected from development, and the state has set a new target, to conserve 40 percent of its land by 2040.

The Rangeley Lakes region can often feel like a forgotten corner of Maine, far from the state’s famed coasts or cities. This western stretch is remote, rugged woodland. Forests become impassable in spring’s muddy months and cool mountain streams teem with a trout population that draws legions of recreational fishers. It’s also a part of the state where logging and timber hauls have indelibly shaped the land and livelihoods of those who live there.

Now about 78,000 acres surrounding the Rangeley Lakes may soon be linked to 500,000 acres of protected land reaching across central Maine to New Hampshire. A project announced March 18 and agreed to by four leading conservation groups and a 70-year-old timber company aims to bolster a priority spawning ground for brook trout, broaden a migration corridor for wildlife and restrict future development in the woodlands.

The plan to permanently protect lands around Maine’s Magalloway River is the brainchild of the Ran

For hundreds of millions of people living in India and Pakistan, the early arrival of summer heatwaves has become a terrifying reality that’s testing survivability limits and putting enormous strain on energy supplies, vital crops and livelihoods.

Both countries experience heatwaves during the summer months of May and June, but this year’s heatwave season has arrived sooner than usual and is predicted to last longer too.

Parts of Pakistan are likely to experience heat up to 8 degrees Celsius above normal between April 14-18, according to the country’s meteorological department. Maximum temperatures in Balochistan, in country’s southwest, could reach up to 49 degrees Celsius (120 Fahrenheit).

That’s like living in Death Valley – the hottest and driest place in North America – where summer daytime temperatures often climb to similar levels.

The world’s largest meat company, JBS, looks set to break its Amazon rainforest protection promises again, according to frontline workers.

Beef production is the primary driver of deforestation, as trees are cleared to raise cattle, and scientists warn this is pushing the Amazon close to a tipping point that would accelerate its shift from a carbon sink into a carbon emitter. JBS, the Brazil-headquartered multinational that dominates the Brazilian cattle market, promised to address this with a commitment to clean up its beef supply chain in the region by the end of 2025.

In a project to understand the barriers to progress on Amazon deforestation, a team of journalists from the Guardian, Unearthed and Repórter Brasil interviewed more than 35 people, including ranchers and ranching union leaders who represent thousands of farms in the states of Pará and Rondônia. The investigation found widespread disbelief that JBS would be able to complete the groundwork and hit its deforestation tar

The spotted salamander has long been a unique part of Homewood’s history. Since at least the 1960s, and likely much longer, experts say, the amphibians have spent much of their time burrowing on the slopes of Shades Mountain, making their homes beneath the fallen leaves and limbs of the forest.

Once a year, as temperatures in Alabama begin to climb, the amphibians migrate from the mountain’s slopes across South Lakeshore Drive, a two-lane road, to the springtime, “vernal” pools located in a narrow patch of woods adjacent to existing sports fields that line Shades Creek.

By 2003, city officials officially designated a nearly half-mile stretch of South Lakeshore Drive as a salamander crossing—painted crosswalks and street signs included. By the next year, the city hosted the first Salamander Festival, a tradition that’s continued to this day. In 2024, more than 900 attendees flocked to Homewood for the event, according to organizers.

Now, though, residents of Homewood fear the worst

In the summer of 2023, a dozen people willingly walked into a steel chamber at the University of Ottawa designed to test the limits of human survival. Outfitted with heart rate monitors and temperature probes, they waited in temperatures of 42 degrees Celsius, or 107 degrees Fahrenheit, while the humidity steadily climbed, coating their bodies in sweat and condensation. After several hours, their internal body temperatures began ratcheting upward, as the heat cooked them from the outside in.

“Few people on the planet have actually experienced temperatures like this,” said Robert Meade, a postdoctoral researcher in epidemiology at the Harvard School of Public Health who led the study. “Imagine moisture condensing on the skin like a glass of water on a hot day. That’s how hot it was, compared to skin temperature.”

Their experiment tested the body’s ability to cope with extreme heat by exposing participants to temperatures at which they could no longer cool themselves. [Their study](htt

In an internal FEMA memorandum obtained and first reported by Grist, the Trump administration announced its plans to dismantle that program — the biggest climate adaptation initiative the federal government has ever funded — even as disasters incur hundreds of billions of dollars worth of damages across the United States.

“BRIC was yet another example of a wasteful and ineffective FEMA program,” a FEMA spokesperson told Grist. “It was more concerned with climate change than helping Americans effected by natural disasters.”

BRIC generally shoulders 75 percent of the cost of a given resilience project, and up to 90 percent of the cost of projects in disadvantaged communities. The program’s emphasis on equity is what may have marked it for demolition — the Trump administration has been systematically dismantling Biden-era efforts to infuse equity into governmental programs and direct more climate spending toward underrepresented groups.

The decision comes as at least seven people were

In Central Texas, a bitter fight over a $1 billion water project offers a preview of the future for much of the state as decades of rapid growth push past the local limits of its most vital natural resource.

On one side: Georgetown, the fastest growing city in America for three years straight, which in 2023 signed a contract with an investor-funded enterprise to quickly begin importing vast volumes of water from the Simsboro Formation of the Carrizo Wilcox Aquifer, 80 miles to the east.

On the other side: the cities atop the Simsboro that rely on its water. Bryan, College Station and the Texas A&M University System, a metro area with almost 300,000 people, have sued a local regulator to stop the project. A trial is set for the first week of May.

District manager Alan Day feels for the cities of Bryan and College Station. To an extent, he said, they are right. The more pumping from the aquifer, the sooner everyone will reach conditions of scarcity, though he doesn’t think it will h

The White House is weighing an executive order that would fast-track permitting for deep-sea mining in international waters and let mining companies bypass a United Nations-backed review process, according to two sources with direct knowledge of the deliberations.

If signed, the order would mark U.S. President Donald Trump's latest attempt to tap international deposits of nickel, copper and other critical minerals used widely across the economy after recent efforts in Greenland and Ukraine. Trump earlier this month also invoked emergency powers to boost domestic minerals production.

The International Seabed Authority - created by the United Nations Convention on the Law of the Sea, which the U.S. has not ratified - has for years been considering standards for deep-sea mining in international waters, although it has yet to formalize them due to unresolved differences over acceptable levels of dust, noise and other factors from the practice.

Trump's deep-sea mining order is likely to

More than 1,900 members of the National Academies of Sciences, Engineering and Medicine signed an open letter warning Americans about the “danger” of the Trump administration’s attacks on science. The letter comes amid the administration’s relentless assault on US scientific institutions which has included threats to private universities, federal grant cancelations and ideological funding reviews, mass government layoffs, resignations and censorship.

“We see real danger in this moment,” the letter states. “We hold diverse political beliefs, but we are united as researchers in wanting to protect independent scientific inquiry. We are sending this SOS to sound a clear warning: the nation’s scientific enterprise is being decimated.”

“The administration is slashing funding for scientific agencies, terminating grants to scientists, defunding their laboratories, and hampering international scientific collaboration,” the letter states. “The funding cuts are forcing institutions to pause res

The world is fast approaching temperature levels where insurers will no longer be able to offer cover for many climate risks, said Günther Thallinger, on the board of Allianz SE, one of the world’s biggest insurance companies.

The argument set out by Thallinger in a LinkedIn post begins with the increasingly severe damage being caused by the climate crisis: “Heat and water destroy capital. Flooded homes lose value. Overheated cities become uninhabitable. Entire asset classes are degrading in real time.”

“We are fast approaching temperature levels – 1.5C, 2C, 3C – where insurers will no longer be able to offer coverage for many of these risks,” he said. “The math breaks down: the premiums required exceed what people or companies can pay. This is already happening. Entire regions are becoming uninsurable.”

“This applies not only to housing, but to infrastructure, transportation, agriculture, and industry,” he said. “The economic value of entire regions – coastal, arid, wildfire-prone

One of the most extended U.S. flood episodes of recent years is on tap to begin late Wednesday, April 3, and stretch into the following weekend. The NWS Weather Prediction Center has issued four consecutive days of moderate flood risk for Wednesday through early Sunday.

The threat of tornadoes, destructive winds, and damaging hail will peak from Wednesday afternoon, April 2, into early Thursday. Then comes the deluge — perhaps a foot or more of rain, adding up to what could be some of the heaviest three- or four-day totals ever recorded in what is normally a moist region notorious for flooding.

According to the U.S. Department of Transportation, approximately one-third of the nation’s residents don’t have driver’s licenses. In her 2024 book “When Driving is Not an Option: Steering Away from Car Dependency,” disability advocate Anna Zivarts argues that not only is America’s car-centric infrastructure harmful to the climate, it also fails to meet the everyday needs of many Americans.
