The Holocene Thermal Maximum

The timing, dynamics, and cause of the Holocene Thermal Maximum in the Arctic


A major goal of PARCS research is to understand the nature and consequences of warmth in the Arctic and its impact on the global climate system. Here we describe such a warming that occurred during the early to middle Holocene. We developed a network of sites with paleoenvironmental records derived from lake and marine sediment cores, glaciers, and other sources. These data are used to identify spatial-temporal patterns of warmth on time scales ranging from decades to millennia. For manageability, we chose to describe first the western Arctic (Kaufman et al. 2004). Our description and analysis of the eastern Arctic Holocene Thermal Maximum will be complete by late 2005.
