PARCS (Paleoenvironmental Arctic Sciences)
The Last Interglacial in the Arctic:
An International Meeting 12,13 October 2002, Coastal Maine, USA
The most recent effort to summarize the Arctic during the last interglacial was coordinated by LIGA (dominantly the terrestrial records) in the early 1990s, which resulted in a dedicated issue of Quaternary Research. In the subsequent decade, substantial progress has been made on four fronts: 1) LIG records from Arctic lake and bog sediments, 2) LIG records from the Arctic Ocean, and improved records from the Nordic Seas, 3) New evidence about the Greenland Ice Sheet during the LIG, and 4) Advances by the climate modeling community in coupled GCMs and in the understanding of feedbacks within the Arctic associated with Arctic warmth.
CAPE (Circum-Arctic PaleoEnvironments) and PARCS (Paleoenvironmental Arctic Sciences) are sponsoring a small working group meeting to provide a forum for the international community to present evidence for environmental conditions during the peak of the last interglacial, with a focus on quantitative estimates of summer warmth and to compare paleo-data with model simulations for the circum-Arctic at the last interglacial (LIG). The LIG appears to have been substantially warmer in the Arctic than at any time during the Holocene. The meeting will address how much warmer the Arctic was in the LIG, and whether there are there thresholds in the ocean/atmosphere/cryosphere that are pertinent to future warming.
