"A High Arctic Perspective on Holocene Climate Change"

Abstract: 

The Arctic is ground zero for future climate warming due to a number of important amplification processes that exist at high latitudes. Changes within the Arctic cryosphere, atmosphere, and ocean also impact climate at lower latitudes, through teleconnections within the climate system. During the past few years, we have been recovering lake sediment cores from throughout the Svalbard Archipelago and using these sedimentary records to document the Holocene climate history of this sensitive sector of the High Arctic, which is an important gateway for the exchange of heat between the North Atlantic and Arctic. Using a combination of approaches, we have developed continuous records of summer temperature, glacier activity, isotopes in precipitation, and the varying size of marine seabird populations, all of which document the dynamic natural climate variability of the region during the past 12,000 years. In this talk, I will present a number of the climate records we have developed and explore what they indicate about the past behavior of the Arctic climate system.
