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...

ESA and NASA satellites deliver first joint picture of Greenland Ice Sheet melting

Academics from Northumbria University are part of an international research team which has used data from satellites to track changes in the thickness of...

Ice is melting, seas are rising—how scientists are tracking the changes

Will the sea rise by 20 cm or 3 meters by 2100? This is obviously an interesting question to answer. Predicting the sea level...

Melting sea ice in Antarctica causes ocean storms, scientists say

The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according...
