Exposure to two compounds approved can result in ‘sudden death’ and range of other serious health risks, lawsuit warns

The Trump administration has approved two new datacenter chemicals to which exposure can result in “sudden death” and a range of other serious health risks, like cancer, eye corrosion, neurological damage and reproductive harm, a new lawsuit warns.

The two compounds approved by the Environmental Protection Agency (EPA) for import and immediate use in facilities across the US are photoacid generators that also appear to be Pfas “forever chemicals”, though it is unclear because much of the EPA documents are redacted. Some Pfas are commonly used in the production of semiconductors.

This article was amended on 26 August 2026. A previous version said the EPA concedes that the chemicals present an “unreasonable risk” to workers. It has been updated to say the chemicals may present an unreasonable risk.

Jack Klein takes heat readings, gives fans to overheated passengers and lugs big jugs of water into the stations

On a recent August day in the subterranean furnace of New York City’s subway, one bearded, curly haired man was studying his phone for different reasons than the other wilting passengers – to track the soaring temperatures and ponder how underground train stations can cool down in an era of climate crisis.

Jack Klein, a 31-year-old construction site manager, has in the past two years taken it upon himself to become a sort of guerrilla subway heat operative, sticking teardrop-shaped thermometers to steel beams in seven of the hottest Manhattan stations and posting social media videos of the hades-like summer temperatures that commuters have to endure.

As wildfires rage and intense heat builds across the region, daytime highs of 110-11F (43-46C) are forecast

Surging temperatures are expected to broil more than 45 million people as a heat dome settles in across the south-western US through the end of August and into early September, according to the National Weather Service (NWS).

As wildfires rage in some parts and intense heat builds across the region, daytime highs of 110-115F (43-46C) are forecast, with limited cooling relief in the evenings and overnight. Experts predict that some record highs could be tied or broken this month and the weather agency warned of the scorching late summer heat as a potential health hazard.

Trump administration proposes new rule to dismantle requirement for datacenters to publicly report air pollution

A new rule proposed by the Trump administration aims to kill public notification for datacenter air pollution, public health advocates warn, and allow emission permits to be issued behind closed doors.

The datacenters are often sources of nitrogen oxide, which helps form ozone, carbon monoxide and heavy metals, among other pollutants.

There has been a 76% increase in under-construction gas-fired projects amid ‘frenzy’ to build more datacenters

The US has surged ahead of China in the building of new gas-fired power generation, largely to feed a boom in artificial intelligence (AI) that is adding vast amounts of planet-heating emissions, a new analysis has found.

For decades, China’s rapid economic growth has seen it outpace the US in the addition of new gas power generation but a recent “frenzy” in datacenter construction for AI has reversed this, said Global Energy Monitor (Gem) in its new report.

In Trump administration’s plan, California, Arizona and Nevada face about a 20% cut to water supply over two years

Nevada filed a federal lawsuit on Monday challenging the Trump administration’s new plan for the imperiled Colorado River, launching what could become the first of many court battles over the waterway that supplies 40 million people, dozens of tribes and 5.5m acres of farm land across the American west.

The federal plan, issued Friday, cut roughly 20% from the water supplied to lower basin states – Nevada, Arizona and California – over the next two years, with a potential for harsher cutbacks in the future, based on conditions.

Man, 68, was left searching for help in 116F weather after his car became stuck in mud along remote park road

A French tourist recently died in Death Valley national park after a car mishap left him stranded in 116F (47C) weather.

The visitor, identified as 68-year-old Pierre Michel Formosa, was traveling with another French man along the park’s remote West Side Road when their vehicle became stuck in mud near Queen of Sheba Mine Road.

Tens of thousands are still under evacuation orders or warnings amid ‘human-caused’, wind-driven blaze

The Hawk fire is about 27% contained, authorities said on Monday afternoon, two days after the fast-moving, wind-driven wildfire sparked near Reno, Nevada.

Authorities added that 23,000 people are under a “go-now” order and 40,000 people are under a “get-set” warning, an improvement from the 90,000 Nevadans under evacuation orders or warnings on Monday morning.

The Democratic and the Republican candidate each blame the other for the bungled recovery effort after storm struck region

Two years after North Carolina suffered the worst natural disaster in its history when Hurricane Helene struck the state’s western half, life in the hardest-hit areas appears back to normal. Downtowns are lively, blocked roads have been reopened and rivers are flowing below their banks.

But the telltale evidence of the disaster’s expensive impacts can still be seen – from “for rent” signs in storefronts whose businesses never came back to debris from the storm still lurking in some waterways. And in the race for North Carolina’s US Senate seat, it’s almost as if the hurricane never left.

Human-caused Hawk fire covers more than 15,000 acres as blaze approaches University of Nevada campus in Reno

A fast-moving Nevada wildfire exploded to more than 15,000 acres (6,000 hectares) on Sunday, pushing from the Sierra foothills toward the center of Reno and urging nearly 90,000 residents to evacuate as flames threatened neighborhoods and reached the edge of the University of Nevada campus.

The Hawk fire’s “GO NOW” evacuation zone had expanded to the edge of the university campus as strong, gusty winds, low humidity and dry vegetation fueled the blaze, according to Truckee Meadows Fire and Rescue in Reno. Of those urged to evacuate, 42,000 were under strict orders. An additional 45,000 people were in the evacuation warning zone, and encouraged to leave now and be prepared to stay away for several days to clear the roads for first-responders.

Capitalism and the climate crisis are conspiring to destroy the concept of seasons. I’ll take solace in my pumpkin spice

Happy spooky season, everyone! Get those jack-o’-lanterns out, because Halloween is just around the corner!

Just kidding, no, it’s not.

Since Hurricane Sandy in 2012, a growing labor movement has addressed the climate crisis and economic inequality

Ryan McElroen had spent years repairing the New York City subway underground when he got the opportunity to work in the middle of the ocean.

“I had no views other than the darkness at work,” he said. “Then I went polar opposite.”

Beach patrols report hundreds of stings a day as warmer waters and drought create favorable conditions for jellyfish

An unusually high number of jellyfish are crowding Delaware’s beaches this summer amid climate change and other environmental factors – keeping some beachgoers out of the ocean and stinging lifeguards as well as bathers.

Beach safety patrols in the state have reported hundreds of daily stings as the jellyfish have increased with intensifying environmental factors, including warmer waters, hot and dry conditions, and water circulation favorable to the invertebrates.

The 10-year blueprint mandates water cuts of up to 40% for California, Arizona and Nevada

It’s official: after years of tense negotiations and missed deadlines, there is finally a plan to govern the future of the imperiled Colorado River - or at least the makings of one.

With the previous framework set to expire in October, the US Bureau of Reclamation publicly released its proposal for a new plan on Friday.

State sought to stop system off coast of Santa Barbara from resuming operations after Trump ordered its reopening

An oil pipeline can continue to operate off the California coast after a judge gave it the green light this week, despite the opposition of state regulators and environmental groups.

The system off the coast of Santa Barbara resumed operations earlier this year for the first time in more than a decade after Donald Trump ordered Sable Offshore Corporation to reopen it, citing US energy needs during the war in Iran.

Administration’s plan to scrap drilling-free buffer zone around New Mexico site prompts scrutiny from Unesco

The Trump administration’s push to expand oil and gas extraction across the US is set to bring drilling near cherished natural and cultural sites, raising alarm among conservationists and prompting questions from the UN’s heritage body.

Unesco said it had received information on the administration’s plan to scrap a drilling-free buffer zone around the Chaco Culture national historical park in New Mexico, a world heritage site and one of the most important cultural areas in the US. A Unesco spokesperson said it had procedures regarding “potential threats” to a world heritage property and was awaiting a response from the federal government as to its impact.

Regulations that would block sale of older tires praised by environmental groups amid rightwing backlash

California has become the first state in the nation to mandate that replacement tires be energy efficient, a major auto industry regulation set to block the sale of older tires and make vehicles on the road greener.

State regulators have said the new rules will reduce emissions and drivers’ fuel costs. But the rules – which come as the Trump administrations fights to block other California restrictions to promote greener cars – have already sparked a rightwing backlash, with one conservative news outlet calling the policies a “massive overreach”.

Discovery marks latest grim finding in lake as water levels in crucial reservoir outside Las Vegas continue to decline

Human remains have once again been discovered at Lake Mead outside Las Vegas, Nevada, marking the latest in a line of gruesome discoveries as water levels in the crucial reservoir continue to drop, authorities said.

These remains were discovered on 16 August, USA Today reported. The National Park Service (NPS) told the outlet there did not appear to be anything suspicious about the body.

Image captured in early June shows animal foraging in the waterway in first since early 1900s, signaling its recovery

An otter has been spotted in the Bronx River for the first time in more than 100 years, in a further sign that New York’s previously befouled waterways are recovering some of their ecological health.

The North American river otter was photographed by a motion-activated camera foraging near some vegetation in the Bronx River, a waterway that flows through New York’s Bronx and empties into the East River.

Firefighters describe being pushed to limit by a brutal wildfire season, with key leadership roles going unfilled

The US has faced a critical shortage of firefighters at the US Forest Service (USFS) this summer as thousands of fires erupted across the country.

Despite officials’ claims that the firefighting workforce was stronger than ever, the agency has failed to keep pace with escalating conditions and the catastrophic fires fueled by them, according to nine firefighters who spoke to the Guardian anonymously, because they are barred from disclosing the information to the public.

Storm also caused destructive flooding and damage to homes and infrastructure with one woman dead

• Tropical storm Lala wreaks ‘devastation’ to some areas of Hawaii’s Big Island

Crews in Hawaii are working to restore power to thousands of residents after the outer bands of Hurricane Lala battered the islands over the weekend, causing destructive flooding and killing one person.

On the hard-hit Big Island, crews were working to clear and restore roads, but some communities on the southern end of the island remained isolated as they were cut off from communication.

Almost 45m acres of national forests could be potentially opened to road construction, drilling and logging

The Trump administration said on Tuesday it plans to rescind the “roadless rule” that has protected old-growth forests in the US for 25 years, potentially opening up almost 45m acres of national forests to road construction, drilling and logging.

Conservationists had feared the announcement was coming since last summer after Brooke Rollins, Trump’s secretary of agriculture, targeted a rule brought in by Bill Clinton’s administration, describing it as “overly restrictive” and an “absurd obstacle” to development.
