A melting glacier contributed to the deadly Nepal floods. We can expect more like this

A melting glacier contributed to the deadly Nepal floods. We can expect more like this

NPR reports: More than a thousand people are missing and at least 400 people are dead after flash flooding tore through Nepal and Tibet early Wednesday. According to initial assessments, a massive chunk of ice snapped off a glacier and tumbled thousands of feet into the valley below. Rock, ice and mud plunged down for miles, washing away communities along the river. Scientists say glaciers in this region, and around the world, are increasingly unstable because of human-caused global warming….

World’s oceans hit highest temperature on record as El Niño grows

World’s oceans hit highest temperature on record as El Niño grows

BBC News reports: The world’s oceans are hotter than ever recorded, new data suggests, as they suffer from human-caused climate change and the growing El Niño weather phenomenon. The average surface temperature of the planet’s seas outside the polar regions hit 21.1C (70F) on Saturday, according to figures from the European Copernicus climate change service. That edges past the 21.09C recorded in March 2024, and is far above average for the time of year. Warmer oceans can have wide-reaching consequences,…

Trump administration moves to allow roads and logging in pristine national forests

Trump administration moves to allow roads and logging in pristine national forests

The New York Times reports: The Trump administration on Tuesday advanced a plan to open nearly 45 million acres of wilderness in national forests to road construction and logging, removing protections that had been in place for a quarter century. The proposal by the U.S. Forest Service would repeal the 2001 “roadless rule,” enacted during the Clinton administration to preserve the wild nature of forest land. It comes as President Trump pressures the agency to increase logging and to thin…

Scientists detect a surprising shift in human blood as atmospheric carbon dioxide rises

Scientists detect a surprising shift in human blood as atmospheric carbon dioxide rises

Science Daily reports: Rising levels of carbon dioxide in the atmosphere may already be influencing human biology. New research has identified long-term changes in blood chemistry that appear to track rising atmospheric CO2, raising concerns that an important blood marker could approach the upper end of its healthy range within the next several decades. The findings may be particularly important for children and teenagers. Because their bodies are still developing, younger generations are expected to experience the greatest lifetime exposure…

A ‘super’ El Niño could transform the Amazon. Is the world’s biggest rainforest doomed?

A ‘super’ El Niño could transform the Amazon. Is the world’s biggest rainforest doomed?

Nature reports: El Niño is back with a vengeance. A mammoth patch of warm water is growing in the equatorial Pacific Ocean, and the US National Oceanic and Atmospheric Administration is giving four-in-five odds that the disruptive climate phenomenon will turn into a “very strong” event by the end of the year. Some forecasters say this El Niño is on track to become the strongest in at least 150 years. For the Amazon rainforest, the timing could hardly be worse….

Potatoes ‘boil’ in the ground as record heatwave sweeps across swathes of Asia

Potatoes ‘boil’ in the ground as record heatwave sweeps across swathes of Asia

The Guardian reports: In a potato field in Yanggu county, 80 miles (130km) north-east of Seoul, Lee Sang-hyuk dug into the soil and found nothing worth saving. A week earlier the crop, located in Gangwon province, had looked fine. Now the potatoes came up soft and collapsing, “like boiled potatoes”, spoiled by heat that had turned the ground into something closer to an oven. “It’s not just one or two fields like this. How can I even put it into…

How AI will accelerate climate change by boosting fossil fuel production

How AI will accelerate climate change by boosting fossil fuel production

The Guardian reports: AI-driven productivity gains enable more planet-heating pollution from fossil fuels than they avoid from renewables, a study has found. Researchers modelled the technical potential for AI to boost clean power generation along with projections for how it can help produce coal, oil and gas. Across 64 scenarios, they found net yearly carbon pollution rose by 0.47-1.8 gigatonnes, or about 1-5% of the energy sector’s annual emissions. The study is the first to quantify the climate impact of…

Global warming is triggering earthquakes

Global warming is triggering earthquakes

Science reports: Climate change is worsening many natural hazards, including droughts, heat waves, and storm surges. Now, a new one has joined the list: earthquakes. Researchers have found that as global warming accelerates melting of mountaintop glaciers, the meltwater, percolating underground, increases the risk of damaging earthquakes. The evidence comes from beneath Grandes Jorasses, a glacier-clad peak in the Alps that is part of the Mont Blanc massif, home to Western Europe’s tallest mountains. Precise seismic records show a heat…

This is what happens when the world is on fire

This is what happens when the world is on fire

John Valliant writes: Water bombers, the air cavalry of wildfire fighting, buzz the treetops like air show stunt pilots as they save the day with surgical drops of water or orange retardant. But what happens when those drops have no effect? When, as a pilot working the massive Gironde Fire just west of Bordeaux, France, described it, “The environment above the fire is so hot that my payload of 10,000 liters of water evaporates in the air.”? Mathieu Jomain, a…

Amazon’s ‘climate pledge’ rings hollow as data center will have the most polluting power plant in the U.S.

Amazon’s ‘climate pledge’ rings hollow as data center will have the most polluting power plant in the U.S.

The New York Times reports: Amazon is investing in a natural-gas-burning power plant, as part of a huge data center in Texas, that could become the largest single source of climate pollution in the United States, the company confirmed Friday. The new gas-burning plant, if built to specifications, would be permitted to release more planet-warming gases than any other power plant in the country. Amazon has been struggling to meet its promise that it would effectively eliminate its planet-warming emissions…

Europe’s summer of reckoning is ‘just the beginning’

Europe’s summer of reckoning is ‘just the beginning’

The New York Times reports: A dense, yellow-orange pall hung over Bordeaux on Sunday, blotting out the sun and blurring the spires of the cathedral in this French city. A swirl of tiny ash particles stung eyes and stuck in throats. Twenty miles west of town, a mammoth forest fire burned so ferociously that it generated its own weather system. “We’ve never seen anything like it,” said Roger Peuron, 89, a retired engineer born before World War II, who was…

Britain could face food shortages as drought continues, farmers warn

Britain could face food shortages as drought continues, farmers warn

The Guardian reports: Britain could face shortages of certain foods after punishing drought in parts of England, the National Farmers’ Union (NFU) has warned as a heatwave was forecast to continue into next week. The UK’s Health Security Agency (UKHSA) has issued heat health alerts for eight regions of England, with temperatures set to rise above 30C in parts of the country. UKHSA said rising temperatures may increase health risks, particularly for vulnerable groups. Farms across the country were affected…

France had never seen a ‘fire cloud’ until this month’s record-smashing blazes

France had never seen a ‘fire cloud’ until this month’s record-smashing blazes

Wired reports: Firefighters in France are confronting a phenomenon never seen in the region before: fire clouds. It’s a sign of the intensity of the blazes burning—and how climate change is upping the odds that they appear. A wave of fires has swept over France and Spain, sending hundreds of thousands fleeing. Firefighters on the frontlines are facing what a spokesperson for the French firefighter association told AFP called an “operational impossibility”—in other words, a “natural force beyond our control.”…

In Texas, the first U.S. city that’s on track to run out of water

In Texas, the first U.S. city that’s on track to run out of water

Science Alert reports: It seems inconceivable, even if you’re aware of the perilous situation that the world’s water supplies are in, but a developed coastal city in Texas that more than 300,000 people call home is now in serious danger of running out of water. The city is Corpus Christi, and difficulties with water scarcity are now coming to a head after years of concerns over shortages. There are multiple issues combining here, perhaps most importantly the arrival of major…

Wildfires across North America won’t be extinguished with tarrifs

Wildfires across North America won’t be extinguished with tarrifs

The Guardian reports: After days of acrid smoke from northern wildfires choking major US cities and inspiring Donald Trump to threaten Canada with tariffs, officials now say the reverse is also happening as parts of Canada issue air quality warnings caused by American fires to the south. Officials in the Canadian province of British Columbia warned in an alert on Saturday evening that smoke from US fires, spurred on by thousands of lightning strikes in the north-east, was creating smoky…

‘Climate free fall’: Why the biggest risk to our economies is yet to be recognized

‘Climate free fall’: Why the biggest risk to our economies is yet to be recognized

Anders Levermann writes: I have studied climate tipping points for more than 20 years, and I’m increasingly concerned that scientists have overlooked the most dangerous aspect of these for societies. The potential collapse of major parts of the Earth system — from ice sheets to ocean circulations — will profoundly alter the warming planet and tip it irreversibly into a different state. But the greatest risks might not lie at that endpoint. How we get there — how the tipping…
