23rd Annual Gregory Lecture. Tracing Arctic climate evolution: from a forested arctic to the present.

17:30, 5 March 2015

The new paleoclimate record from Crater Lake El’gygytgyn (Lake E), NE Russia, provides the first complete record of Pliocene and Pleistocene climate change from the terrestrial arctic high latitudes. These data are now being used to assess the climate evolution of the Arctic since a time when the arctic borderlands were forested and the Greenland Ice sheet did not exist in its present form. Moreover, these data provide a means to better understand inter-hemispheric linkages of natural climate variability, potentially impacting both polar regions over the past few million years. The project continues as a successful multinational collaboration.
