Climate crisis could be destabilising mountain areas like Nepal, experts warn

Climate crisis could be destabilising mountain areas like Nepal, experts warn

The Guardian reports: The devastating flash flood that has ripped through the border communities of Nepal and Tibet has heightened fears that the climate crisis is destabilising the geology of mountain and polar regions, threatening millions of people. Satellite imagery suggests a glacier collapse high in the Himalayas was the primary cause of the deadly torrent of mud, water and ice that tore along the Bhotekoshi River on Wednesday. It swept away buildings and roads and left at least 360…

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,…

How Trump is trying to crush California’s environmental policies

How Trump is trying to crush California’s environmental policies

The New York Times reports: The Trump administration has taken a series of extraordinary steps to attack California’s position as a national leader in environmental protection, enlisting at least a half-dozen federal agencies to undermine the state’s efforts to pivot away from fossil fuels. The stakes are high. Because of its market muscle as the world’s fourth largest economy, California’s environmental regulations have influenced the manufacturers of automobiles and other consumer goods. And its green policies have spread to some…

The fungi in the ocean may be way more important than we realized

The fungi in the ocean may be way more important than we realized

Science Alert reports: Hidden inside tree trunks, between grains of soil, deep within our bodies, and below our feet, fungi seem to wind their way into everything. But did you know fungi actually live in the ocean, too? New research published in PLOS Biology reveals the overlooked role of marine fungi in the carbon cycle by zooming in on the seawater and sediments that line an Arctic fjord in Norway. We’re only just starting to understand how widespread fungi are…

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…

Why rivers are so mathematical

Why rivers are so mathematical

Natalie Wolchover writes: A river has my heart. It’s not the austere, black Thames winding through London, where I was born, but a lazy green one 5,000 miles away, where I spent my adolescence: the Blanco River in Texas. My maternal ancestors have dipped into its waters for generations, as I have on countless summer days. The Blanco is a tributary of the San Marcos, which flows into the Guadalupe, and on into the Gulf of Mexico. You can probably…

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…

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…

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

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

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…
