From the high Yukon to the mountains of Central Asia, melting ice exposes fragile ancient artifacts that tell the story of the past – and provide hints about how to respond to a changing climate.
Survey respondents who overestimated the amount and speed of sea-level rise were more likely to express greater concern. But concern is not always helpful in prompting action.
If emissions continue at their current pace, Antarctica will cross a threshold into runaway sea rise when today’s kids are raising families. Pulling CO2 out of the air later won’t stop the ice loss.
New research shows how fibre-optic cables can monitor the hidden structure of glaciers, teaching us about past and future ice flow.
Greenland’s glaciers have retreated so far that they can no longer support the ice sheet that feeds them. The ice sheet system has reached a new normal of consistent annual ice loss.
Two centuries after it was first sighted by Russian explorers, Antarctica is a key site for studying the future of Earth’s climate – and for global scientific cooperation.
Satellite research confirms its enormous ice sheet is melting faster than most scientists predicted.
These lakes could threaten the future stability of parts of the Antarctic ice sheet.
Studies show that the Arctic is heating up twice as fast as the rest of the planet.
Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical ‘cores’ of the sediment and rock that’s as much as two miles down at the ocean floor.
Last summer one of Antarctica’s floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
We used 11 different satellite missions to track Antarctica’s contribution to rising sea levels.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
The climate secrets contained in an ancient tree that lived through abrupt global change reveal how Antarctica can trigger rapid warming in the north by dumping cold water into the Southern Ocean.
Greenland’s ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.
After record-breaking amounts of sea ice in Antartica, this year we’re seeing record lows.
New projections suggest the world could warm 3-7 degrees over coming centuries.
A glaciologist develops a lightweight method for probing the depths of Greenland’s ice sheet to answer a crucial question: How fast is it melting?
