Sea ice strongly linked to climate change in past 90,000 years

“The Arctic sea ice responded very rapidly to past climate changes. During the coldest periods of the past 90,000 years the sea ice edge spread relatively quickly to the Greenland-Scotland Ridge, and probably far into the Atlantic Ocean.” says first author Ulrike Hoff, a r
