Warming is making Himalayan rivers more unstable, with potentially serious consequences downstream. The Himalayas do more than tower over Asia. They help store and release the water that feeds some of the continent’s most important rivers, supporting nearly 2 billion people from mountain valleys to densely populated plains. Now, a new study suggests that this [...]

An Antarctic glacier just collapsed at record speed, stunning scientists and raising fears about the future of Earth’s ice. Antarctica’s Hektoria Glacier has undergone one of the fastest glacier retreats ever documented, surprising scientists with how quickly the ice disappeared. Between January 2022 and March 2023, the glacier retreated by about 25 kilometers (15 miles). [...]

A global analysis of more than 3,100 surging glaciers reveals a dynamic and unevenly distributed phenomenon that challenges conventional expectations about glacier retreat. While most of the world’s glaciers are steadily shrinking as temperatures rise, a small subset behaves in a very different way. These glaciers can suddenly accelerate, surge forward, and reshape entire landscapes [...]

New radar data reveals Alaska’s glaciers are melting longer and reacting faster to heat. Alaska’s glaciers are not just shrinking. They are staying in melt mode for longer stretches of the year. Using satellite radar, researchers found that for every 1 degree Celsius (1.8 degrees Fahrenheit) increase in average summer temperature, glaciers across Alaska experience [...]

A pioneering robotic submarine that explored beneath Antarctica’s glaciers has been lost, but its discoveries are reshaping our understanding of ice melt as a more advanced successor is prepared to continue the mission. A new robotic submarine is set to take over where Ran left off, reopening one of the most challenging frontiers in Earth [...]

Drilling through 500 feet of floating ice into the Antarctic Ocean floor, climate scientists have retrieved a rare 23-million-year record of sediments that helps demonstrate why the planet’s southern ice shield could determine the fate of distant low-lying coastal areas. The layers of rock, silt and fossils are like pages in a book of geological […]

Scientists testing a popular climate theory in Antarctica found that melting glaciers deliver far less iron to the ocean than previously believed. Most of the iron feeding carbon-hungry algae actually comes from deep water and sediments, not from the ice itself. A Climate Hope in the Southern Ocean For years, researchers studying the Southern Ocean [...]
