Using a technique called structured expert judgment, researchers asked 22 ice sheet experts to estimate plausible ranges for future sea level rise due to the projected ... read more
In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected, according to a ... read more
An international team of scientists has found part of the world's largest ice shelf is melting 10 times faster than the ... read more

New research on how glaciers in the European Alps will fare under a warming climate has come up with concerning results. Under a limited warming scenario, glaciers would lose about two-thirds of ... read more

Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise. Glaciers alone lost more than 9,000 billion tons of ice since ... read more

A new paper shows that air temperature is the 'smoking gun' behind climate change in the ... read more

Glaciology experts have issued evidence that a large section of the Brunt Ice Shelf in Antarctica, which is home to the British Antarctic Survey's Halley Research Station, is about break off. ... read more

Glaciers extending into freshwater lakes can form long, submerged terraces that menacingly rise above the surface when icy chunks fall into the ... read more

The dramatic loss of ice in the Arctic is influencing sea-ice transport across the Arctic Ocean. Today only 20 percent of the sea ice that forms in the shallow Russian marginal seas of the Arctic ... read more

NASA research shows that Jakobshavn Glacier, which has been Greenland's fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. The glacier is ... read more

Researchers Unveil Effects of Dust Particles on Cloud Properties

Scientists have generated significant findings that highlight the impact of high-latitude dusts on the conversion of clouds' water droplets to ice -- or glaciation -- within low-level clouds in ... read more

Antarctic Snowfall Dominated by a Few Extreme Snowstorms

A new study reveals the importance of a small number of intense storms around Antarctica in controlling the amount of snow falling across the ... read more

Tall Ice-Cliffs May Trigger Big Calving Events -- And Fast Sea-Level Rise

Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving ... read more

Arctic Sea Ice 2019 Wintertime Extent Is Seventh Lowest

Sea ice in the Arctic appears to have hit its annual maximum extent after growing through the fall and winter. The 2019 wintertime extent reached on March 13 ties with 2007's as the 7th smallest ... read more

Uncertain Projections Help to Reveal the Truth About Future Climate Change

Scientists explain how differing climate model projections can be used collectively to reduce uncertainties in future climate ... read more

New Perspective on Changing Travel Conditions in Arctic Communities

Inuit communities' travel skills and regional knowledge have helped mitigate the effects of Arctic climate change on travel conditions, according to a new ... read more

It's Raining on the Greenland Ice -- In the Winter

Rainy weather is becoming increasingly common over parts of the Greenland ice sheet, triggering sudden melting events that are eating at the ice and priming the surface for more widespread future ... read more

Migrating Snowline Plays Outsized Role in Setting Pace of Greenland Ice Melt

Meltwater from Greenland's ice sheet is a leading contributor to global sea level rise, and a new study shows that an underappreciated factor -- the position of the snowline on the ice sheet -- ... read more

New Satellite Keeps Close Watch on Antarctic Ice Loss

A recently-launched satellite mission has captured precision data on the elevation of the Antarctic ice sheet proving a valuable addition to monitoring efforts in the region, according to new ... read more

Thousands of Tiny Quakes Shake Antarctic Ice at Night

Scientists placed seismometers on the McMurdo Ice Shelf and recorded hundreds of thousands of tiny 'ice quakes' that appear to be caused by pools of partially melted ice expanding and ... read more

Human 'Footprint' on Antarctica Measured for First Time

The full extent of the human 'footprint' on Antarctica has been revealed for the first time by new research which used satellite images to measure stations, huts, runways, waste sites and ... read more

Mystery of Green Icebergs May Soon Be Solved

Researchers have proposed a new idea that may explain why some Antarctic icebergs are tinged emerald green rather than the normal blue, potentially solving a decades-long scientific ... read more

Antarctic Ice Shelves Buckle Under Weight of Meltwater Lakes

The filling and draining of meltwater lakes has been found to cause a floating Antarctic ice shelf to flex, potentially threatening its ... read more
