Abrupt mid-twentieth-century decline in Antarctic sea-ice extent from whaling records

An analysis of whaling records indicate that, averaged over October to April, the Antarctic summer sea-ice edge has moved southwards by 2.8 degrees of latitude between the mid 1950s and early 1970s. This abrupt change poses a challenge to model simulations of recent climate change, and could imply c...

Summary:An analysis of whaling records indicate that, averaged over October to April, the Antarctic summer sea-ice edge has moved southwards by 2.8 degrees of latitude between the mid 1950s and early 1970s. This abrupt change poses a challenge to model simulations of recent climate change, and could imply changes in Antarctic deep-water formation and in biological productivity.
