Arctic Sea-Ice is much THINNER 

Than we Thought

The thickness, and thus volume of remaining Arctic sea-ice is much less than we think. 

In late winter, what we thought was 3 ft thick ice is actually only about 2.8 ft thick; 2 ft thick ice is really only about 1.5 ft thick.

      

Ice volumes are lower by 11% to 25% depending on the overall thickness patterns.  

Terribly significant news, since sea-ice loss means broken persistent jet streams and many more, severe, longer duration extreme weather events.
