Himalayas Are Experiencing an “Exceptional” Loss of Glacial Mass

by Rishika Pardikar 10 February 202210 February 2022

The Himalayas have lost 40% of their glacial mass since the Little Ice Age. East Nepal and Bhutan have experienced the most rapid losses.

“Sticky” Ice Sheets May Have Led to More Intense Glacial Cycles

by Clara Chaisson 5 January 202211 May 2022

New research attributes a shift to longer, stronger glacial cycles to increased friction between ice sheets and bedrock in the Northern Hemisphere 1 million years ago.

Arctic Unicorns and the Secret Sounds of a Glacial Fjord

by Evgeny A. Podolskiy 9 December 202123 June 2022

The successful deployment of a seafloor seismometer near the calving front of a Greenland glacier has opened a new avenue to study hidden glacial processes and the behavior of fjord-dwelling wildlife.

Quit Worrying About Uncertainty in Sea Level Projections

by Jeremy Bassis 30 November 202124 January 2022

Emphasizing uncertainty in model projections of long-term sea level rise is a misguided approach. Instead, we should focus on communicating what we do know while improving model confidence.
