about the alarming increase in the rate of loss of multi-year ice in the Arctic.

Key Points:


  1.  MYI area loss in the Beaufort Sea quadrupled from 46,000 km2yr-1in 
1997-2001 to 183,000 km2yr-1in 2017-2021.


  1.  MYI area loss peaked at 385,000 km2in 2018, which is close to the annual 
MYI area export through Fram Strait.


  1.  The Beaufort Sea has become a MYI export pathway rivaling Fram Strait, 
encouraging the transition to a seasonal Arctic sea ice cover.
