Ice streams move due to tiny ice quakes: Dynamics of Greenland’s ice decrypted

The great ice streams of the Antarctic and Greenland are like frozen rivers, carrying ice from the massive inland ice sheets to the sea—and...

Arctic sea ice levels second lowest on record for January: US data

The sea ice in the Arctic was the second lowest on record for January last month, according to a US analysis released Tuesday, with...

Cracks in Greenland Ice Sheet grow more rapidly in response to climate change, study warns

The Greenland Ice Sheet is cracking open more rapidly as it responds to climate change. The warning comes in a new large-scale study of...

First major chunk breaks off world’s biggest iceberg

An enormous chunk has broken off the world's largest iceberg, in a possible first sign the behemoth from Antarctica could be crumbling, scientists told...

‘Last Ice Area’ in the Arctic could disappear much sooner than previously thought

The Arctic's "Last Ice Area" (LIA)—a vital habitat for ice-dependent species—might disappear within a decade after the central Arctic Ocean becomes ice-free in summer,...

Global sea level very likely to rise between 0.5 and 1.9 meters by 2100 under a high-emissions scenario

An interdisciplinary team of researchers from NTU Singapore, and Delft University of Technology (TU Delft), The Netherlands, has projected that if the rate of...

How is Antarctica melting, exactly? Crucial details are beginning to come into focus

The size of the Antarctic ice sheet can be hard to comprehend. Two kilometers thick on average and covering nearly twice the area of...

Permafrost in climate change: Models predict Arctic’s response to global warming

The Arctic is heating up particularly fast as a result of global warming—with serious consequences. The widespread permafrost in this region, where soils currently...

Antarctic sea ice rebounds from record lows: US scientists

Antarctic sea ice rebounded in December after a long period of record lows, US scientists said, giving pause to speculation that Earth's frozen continent...

Could habitable planets orbiting white dwarfs retain their oceans? Maybe

Potentially habitable exoplanets are so incredibly common that astronomers have started to consider more unusual situations where life might arise. Perhaps life can be...

Decades of observations uncover secrets of Antarctic fast ice

Sea ice that has persisted for at least 15 days and is held fast to the shoreline is called "fast ice." Around Antarctica, fast...

Massive Antarctic icebergs may calve at random, analysis suggests

Antarctica is losing ice quickly, in part because of climate change. Massive calving events, such as the one that formed the Delaware-sized (5,800 square...
