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.

28 January 2019

Researchers have descended on West Antarctica to begin a five-year study of Thwaites Glacier. The joint US-UK project aims to better understand the glacier's ice loss and potential impact on sea level rise.

26 November 2018

CIRES and NSIDC scientists Ted Scambos and Bruce Wallin are traveling to Antarctica. You can follow the research team's progress, read about previous research, and learn about the team members at the expedition blog: On Thin Ice.

22 October 2018

After forty years, satellite data has made sea ice one of the most studied natural phenomena on Earth, revealing trends in sea ice extent, concentration, and thickness.
