Arctic coastal sea ice thinning twice as fast than thought

Sea ice in key Arctic coastal regions is thinning at a rate of 70–100% faster than previously thought.

These values, reported in a paper recently published in The Cryosphere, are derived when the sea ice thickness in the period 2002–2018 is calculated using new snow data with more realistic variability and trends.

Results are outcomes of the Polar+ Snow on Sea Ice and ArcticSummIT: Arctic Summer Ice Thickness projects.
