Younger Dryas blows hot and cold The Younger Dryas — a period of sudden cooling in the Northern Hemisphere about 12,900 years ago — is perhaps the best-known example of abrupt climate change. But the global extent of the Younger Dryas is a topic of intense debate, particularly in the record of glacial behaviour in New Zealand. A new reconstruction of the growth and retreat patterns of glaciers in the Southern Alps in New Zealand at the time of the Younger Dryas supports the suggestion that temperature reductions in the north caused warming and glacial retreat in the Southern Hemisphere through a series of climate feedbacks.
