Critical Atlantic current significantly more likely to collapse than thought

Critical Atlantic current significantly more likely to collapse than thought

The Guardian reports: The critical Atlantic current system appears significantly more likely to collapse than previously thought after new research found that climate models predicting the biggest slowdown are the most realistic. Scientists called the new finding “very concerning” as a collapse would have catastrophic consequences for Europe, Africa and the Americas. The Atlantic meridional overturning circulation (Amoc) is a major part of the global climate system and was already known to be at its weakest for 1,600 years as…

Apollo vs Artemis: How the Earth changed in 58 years

Apollo vs Artemis: How the Earth changed in 58 years

Richard Hollingham writes: After the Apollo 8 crew captured the iconic Earthrise photo in 1968, Artemis astronauts have recreated the image, revealing changes to our fragile blue planet. When the commander of Apollo 8, Frank Borman, first saw the far side of the Moon from his spacecraft window in 1968 he was struck by its desolate appearance. “The lunar surface was terribly distressed with meteorite craters and volcanic residue,” he told me during a BBC interview in 2018. “It was…

Mass drowning of chicks puts emperor penguins at risk of extinction

Mass drowning of chicks puts emperor penguins at risk of extinction

The Guardian reports: The mass drowning of emperor penguin chicks as sea ice is melted by the climate crisis has led the International Union for Conservation of Nature (IUCN) to declare the species officially in danger of extinction. Emperor penguins rely on “fast” ice – sea ice that is firmly attached to the coast – for nine months of the year. It is where their fluffy chicks are hatched and grow until they have their waterproof feathers. Adults moult every…

A new economic superpower could spark a global retreat from fossil fuels

A new economic superpower could spark a global retreat from fossil fuels

Mark Hertsgaard and Kyle Pope write: The Iran war is also a climate war. Beyond its terrible human costs, the war’s disruptions of oil, gas, fertilizer and other shipments is another reminder of the risks inherent in basing the world economy on fossil fuels. The war’s jets, missiles and aircraft carriers, and the tankers, refineries and buildings they blow up, represent millions of tons of greenhouse gas emissions that further imperil a climate system that is already “very close” to…

Climate physicists face the ghosts in their machines: clouds

Climate physicists face the ghosts in their machines: clouds

Charlie Wood writes: In October 2008, Chris Bretherton lifted off from the coast of northern Chile in a C-130 turboprop plane. It was too dark to see the sandy hills of the Atacama Desert below, but the darkness suited Bretherton just fine. The researcher wasn’t going sightseeing. Seated directly behind the pilots, he kept his focus entirely on the sky. The plane was stuffed with instruments, and its wings bristled with sensors and other devices. Bretherton’s immediate mission was to…

As Trump retreats from climate goals, China is becoming a green superpower

As Trump retreats from climate goals, China is becoming a green superpower

BBC News reports: China has created a desert that no longer just reflects the Sun. It captures it. Aluminium soaks up the rays on the golden dunes of Inner Mongolia, transforming one of the harshest landscapes into one of the world’s largest solar farms. Xin Guiyi, who has lived here all his life, seems to welcome the change. “It used to be so dry and the desert was getting bigger,” he explains, as he mixes feed for his small flock…

China has planted so many trees around the Taklamakan Desert that it’s turned this ‘biological void’ into a carbon sink

China has planted so many trees around the Taklamakan Desert that it’s turned this ‘biological void’ into a carbon sink

Live Science reports: Mass tree planting in China is turning one of the world’s largest and driest deserts into a carbon sink, meaning it absorbs more carbon from the atmosphere than it emits, new research reveals. The Taklamakan Desert (also spelled Taklimakan or Takla Makan) is slightly larger than Montana, stretching across about 130,000 square miles (337,000 square kilometers). It is encircled by high mountains, which block moist air from reaching the desert for most of the year, creating extremely…

Trump regime erases the government’s power to fight climate change

Trump regime erases the government’s power to fight climate change

The New York Times reports: President Trump on Thursday announced he was erasing the scientific finding that climate change endangers human health and the environment, ending the federal government’s legal authority to control the pollution that is dangerously heating the planet. The action is a key step in removing limits on carbon dioxide, methane and four other greenhouse gases that scientists say are supercharging heat waves, droughts, wildfires and other extreme weather. Led by a president who refers to climate…

Point of no return: Hellish ‘hothouse Earth’ getting closer, scientists say

Point of no return: Hellish ‘hothouse Earth’ getting closer, scientists say

The Guardian reports: The world is closer than thought to a “point of no return” after which runaway global heating cannot be stopped, scientists have said. Continued global heating could trigger climate tipping points, leading to a cascade of further tipping points and feedback loops, they said. This would lock the world into a new and hellish “hothouse Earth” climate far worse than the 2-3C temperature rise the world is on track to reach. The climate would also be very…

Trump to direct Pentagon to buy coal in bid to revive industry

Trump to direct Pentagon to buy coal in bid to revive industry

Bloomberg reports: President Donald Trump will unveil plans to use government funding and Pentagon contracts to sustain US coal-fired power plants as he seeks to drive domestic reliance on the fossil fuel. The marquee initiative, set to be announced Wednesday, will come through an executive order, as Trump directs Defense Secretary Pete Hegseth to enter into agreements to purchase electricity from coal plants to power military operations, according to a White House official. The move is expected to tap special…

Nature’s ‘engine is grinding to a halt’ as climate change gains pace, says study

Nature’s ‘engine is grinding to a halt’ as climate change gains pace, says study

Phys.org reports: Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats at an ever-increasing rate, leading to a rapid reshuffling of ecological communities. A new study by researchers at Queen Mary University of London (QMUL) and published in Nature Communications shows this is emphatically not the case. The researchers analyzed a massive database of biodiversity surveys,…

Trump allies near ‘total victory’ in wiping out U.S. climate regulation

Trump allies near ‘total victory’ in wiping out U.S. climate regulation

The New York Times reports: In the summer of 2022, Democrats in Congress were racing to pass the biggest climate law in the country’s history and President Joseph R. Biden Jr. was declaring that global warming posed a “clear and present danger” to the United States. But behind the scenes, four Trump administration veterans were plotting to obliterate federal climate efforts once Republicans regained control in Washington, according to documents reviewed by The New York Times and interviews with more…

We need Greenland. But not in the way Trump imagines

We need Greenland. But not in the way Trump imagines

A year ago, Paul Bierman wrote: Donald Trump has a thing for Greenland. First, he wanted to buy the Arctic island. Then, his son visited for a photo-op. Now, he refuses to rule out using the U.S. military to seize it. Decades ago, the value of Greenland was indeed its strategic location between superpowers and its unique mineral resources. No longer. Today, Greenland’s value is the ice that covers 80 percent of the island. Keeping Greenland’s ice frozen preserves at…

Hundreds of iceberg earthquakes detected at the crumbling end of Antarctica’s Doomsday Glacier

Hundreds of iceberg earthquakes detected at the crumbling end of Antarctica’s Doomsday Glacier

Copernicus / ESA, CC BY By Thanh-Son Pham, Australian National University Glacial earthquakes are a special type of earthquake generated in cold, icy regions. First discovered in the northern hemisphere more than 20 years ago, these quakes occur when huge chunks of ice fall from glaciers into the sea. Until now, only a very few have been found in the Antarctic. In a new study published in Geophysical Research Letters, I present evidence for hundreds of these quakes in Antarctica…

How big a threat is AI to the climate?

How big a threat is AI to the climate?

The Guardian reports: During a golden sunset in Memphis in May, Sharon Wilson pointed a thermal imaging camera at Elon Musk’s flagship datacentre to reveal a planetary threat her eyes could not. Free from pollution controls, the gas-fired turbines that power the world’s biggest AI supercomputer were pumping invisible fumes into the Tennessee sky. “It was jaw-dropping,” said Wilson, a former oil and gas worker from Texas who has documented methane releases for more than a decade and estimates xAI’s…

The Amazon is shifting into a ‘hypertropical’ state unseen for millions of years

The Amazon is shifting into a ‘hypertropical’ state unseen for millions of years

Science Alert reports: A new study of the Amazon rainforest has found the region is shifting toward a ‘hypertropical’ state as droughts become longer, hotter, and more frequent. These conditions have “no current analogue” according to the international team of researchers behind the study. Trees are becoming exposed to whole new levels of stress, and the Amazon’s capacity to absorb carbon dioxide is being reduced, too. So drastic are the contemporary and impending changes, based on data gathered across the…
