For Good Measure: Scientists Collaborate to Track Sea Level Rise From Glaciers in Greenland and Antarctica
Scientists who study both the ice sheets and nearby peripheral glaciers are working together to improve the accuracy of estimated sea level rise.

Key Ocean Current Contains a Warning on Climate
A new study shows that a giant current circling Antarctica has speeded up during past warm periods, eating away at the polar ice. It’s doing it again now.

In Massive Project, Scientists to Probe Deposits Beneath West Antarctic Ice Sheet
Drilling into sub-ice deposits left behind during times when the Earth was warmer than today should provide insights into how a massive ice sheet will react to human-induced climate change.

Closing Out Climate Week: Why 2 Degrees is Too High for the Cryosphere
Experts say that snow and ice loss will create conditions beyond the limits of adaptation for billions of people if climate warming reaches 2 degrees Celsius.

Why Care About the Polar Regions? These Polar Climate Ambassadors Will Tell You.
The polar regions are a critical aspect of the climate crisis, but polar science is not always accessible, especially to young students. The Polar Climate Ambassadors program seeks to help close this gap.

Fast-Wasting Antarctic Glacier Lost Ice Even Faster in Past, Raising Concerns for Future
Some time in the past 200 years, Antarctica’s giant Thwaites Glacier saw a period of retreat much faster than even that observed in recent years. It could be a warning of rapid sea-level rise in the near future.

How Is Climate Change Affecting Ocean Waters and Ecosystems?
Biological oceanographer Hugh Ducklow describes decades of work in far-flung places to understand the evolving ecology of the oceans. The picture is not always clear.

In Sediments Below Antarctic Ice, Scientists Discover a Giant Groundwater System
For the first time, scientists have mapped in detail water locked in a deep basin far under the Antarctic ice. The discovery could have implications for how the continent reacts to, or even contributes to, climate change.

Defying Some Expectations, Southern Ocean Did Not Increase Carbon Uptake in Ice Ages
In much of the world ocean, there is evidence that iron-rich dust blowing from land has fertilized algae during cold period, increasing uptake of carbon from the air, and keeping things frigid. Not here, says a new study.
