Part of the Greenland ice sheet may be close to a tipping point

Data from the Jakobshavn drainage basin of the Central-Western Greenland ice sheet reveals that the distinct mark of this part of the ice sheet has reached a tipping point. That is the conclusion by Niklas Boers from Potsdam ...

1.5C warming cap could 'halve' sea level rise from melting ice

Limiting global warming to 1.5 degrees Celsius could halve how much sea levels rise due to melting ice sheets this century, according to a major new study modelling how Earth's frozen spaces will respond to ever-increasing ...

Can extreme melt destabilize ice sheets?

Nearly a decade ago, global news outlets reported vast ice melt in the Arctic as sapphire lakes glimmered across the previously frozen Greenland Ice Sheet, one of the most important contributors to sea-level rise. Now researchers ...

New study: Thick sea-ice warms Greenland fjords

A new study led by Stockholm University Assistant Professor Christian Stranne shows that thick sea ice outside the fjords can actually increase the sensitivity of Greenlandic fjords to warming. Stranne and a team of researchers ...

What a glacial river reveals about the Greenland Ice Sheet

With data from a 2016 expedition, scientists supported by NASA are shedding more light into the complex processes under the Greenland Ice Sheet that control how fast its glaciers slide toward the ocean and contribute to sea ...

Melting ice sheets caused sea levels to rise up to 18 meters

It is well known that climate-induced sea level rise is a major threat. New research has found that previous ice loss events could have caused sea-level rise at rates of around 3.6 meters per century, offering vital clues ...

Greenland's ice melted away at least once in last million years

The ice sheet atop Greenland —which holds enough frozen water to swamp coastal cities worldwide—has melted to the ground at least once in the last million years despite CO2 levels far lower than today, stunned scientists ...
