Paleoclimate

Paleoclimate data provide just one line of evidence for the reality of human-caused climate change.

Paleoclimate studies and studies of the contemporary Arctic together have identified four potential feedback mechanisms between the impacts of climate change on the Arctic and the global climate system; these are: albedo (reflectivity); greenhouse gas emissions and/or uptake through biological responses to warming; greenhouse gas emissions from methane hydrates released from thawing permafrost; and freshwater fluxes that affect thermohaline circulation.

Effects of climate change on landscape and regional processes and feedbacks to the climate system in the Arctic 2009

Paleoclimate data show that climate sensitivity is ~3°C for doubled CO2, including only fast feedback processes.

Other GCM MIPs of relevance to the ACIA include the Ocean Model Intercomparison Project [43], which is designed to stimulate the development of ocean models for climate research, and the Paleoclimate Modeling Intercomparison Project [44], which compares AGCM/OUML models (see Box 4.1) and AOGCMs in simulations of paleoclimate conditions during periods that were significantly different from the present-day climate.

Paleoclimate modeling experiments have shown that the northward movement of the treeline 6,000 years BP accounted for half of the climatic warming that occurred at that time [108].
