Arctic Ocean changes driven by sub-Arctic seas

New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.

Ice melting Arctic cyclones more common than previously thought

Remember the Arctic cyclone that chopped up the Arctic sea ice in 2012, resulting in a new record low summer extent for the satellite era? It turns out they are…
