Researchers probe remote Alaskan permafrost to see where it thaws, and how deep the thaw goes.

12 February 2019

The Arctic is warming twice as fast as the rest of the world, and sea ice loss plays a large role in this. While warmer conditions lead to more melting of sea ice, the loss of sea ice also makes it warmer - a vicious feedback cycle.

7 February 2019

NSIDC has updated two key data sets from NASA's Airborne Topographic Mapper (ATM) sensor, expanding the range of these data sets from 1993 to 2018.
