Is the Ice Sheet Collapse Inevitable? What Ancient Ice Reveals About Our Future
Scientists from the Mann Research Group drove a climate model both forward and backward in time and discovered significant path dependence in the development of…
Glaciers are massive, persistent bodies of dense ice that are constantly moving under their own weight. They form where the accumulation of snow exceeds its melt over many years, often centuries. Glaciers are primarily found in polar regions like Antarctica and Greenland, but also in mountain ranges around the world, from the Rockies to the Himalayas. As glaciers flow, they shape the landscape through processes like erosion and deposition, creating features such as valleys, moraines, and fjords. Although they cover only about 10% of the world’s land surface, glaciers are vital to the global ecosystem. They store about 69% of the world’s freshwater and act as indicators of climate change, with their retreat providing some of the clearest evidence of global warming. The melting of glaciers has significant implications for sea level rise and freshwater availability, affecting both natural environments and human populations.

MIT researchers have developed a new model to predict glacier flow by studying microscopic defects in ice, revealing significant variations in how ice responds to…
A study using a whaler’s forgotten aerial photos from 1937 shows East Antarctica’s ice has been stable and even grown, despite some early signs of…
Venezuela is the first postglacial nation in the Andes, as its last substantial patch of ice is now considered too small to flow under its…
Satellite data provides the first evidence of warm ocean water intrusion beneath Antarctica’s Thwaites Glacier. For the first time, visible evidence has been captured showing…
Satellite radar data shows substantial seawater intrusion beneath Antarctica’s Thwaites Glacier, causing ice to rise and fall. Using high-resolution satellite radar data, a team of…
Meandering ocean currents play an important role in the melting of Antarctic ice shelves, threatening a significant rise in sea levels. A new study published…
It is not a secret that glaciers are melting, and that it causes a problem with sea levels rising, but a new way of reading,…
Researchers at the Alfred Wegener Institute (AWI) have created simulations of ocean currents beneath the ice of the 79° North Glacier in northeast Greenland. The…
Global warming is unlocking methane reserves, the size of which remains uncertain. A young researcher at the University of Copenhagen found significant amounts of this…
UC Irvine researchers suggest we may be underestimating the severity of sea level rise. Researchers at the University of California, Irvine and NASA’s Jet Propulsion…
A team of scientists from EPFL and Charles University in Prague have discovered that microbial life is set to thrive in mountain streams, as a…
Nestled within the immense wilderness of Antarctica, the Thwaites Glacier stretches impressively across approximately 80 miles on the continent’s western frontier. Despite its monumental scale,…
The surface melting of a high-elevation glacier in the Alps has rendered it unusable for scientific research. Glaciers are natural archives of past climate. In…
There’s enough water frozen in Greenland and Antarctic glaciers that if they melted, global seas would rise by many feet. What will happen to these…
Even if global warming were to stop entirely, the ice volume in the European Alps is projected to decrease by 34% by 2050. Should the…
Alaska’s Columbia Glacier has significantly retreated over 20 km since the 1980s, with climate change being a major factor. Satellite imagery from 2023 highlights the…
Resting atop a shingled sandstone landscape, the Norwegian glacier has been in decline since the late 1990s. Ålfotbreen glacier rests on ledges of sandstone among…
