Polar amplification

Polar amplification

Polar amplification is defined by International Arctic Science Committee on page 23 of the Arctic Climate Impact Assessment "Polar amplification (greater temperature increases in the "Arctic" compared to the earth as a whole) is a result of the collective effect of these feedbacks and other processes." [ [http://www.acia.uaf.edu/pages/scientific.html Arctic Climate Impact Assessment - International Arctic Science Committee] ] It does not apply to the Antarctic, because the Southern Ocean acts as a heat sink. [http://www.realclimate.org/index.php?p=18 RealClimate ] ] It is common to see it stated that "Climate models generally predict amplified warming in polar regions", e.g. Doran et al. [ [http://www.nature.com/nature/journal/v415/n6871/full/nature710.html Access : : Nature ] ] . However, climate models predict amplified warming for the Arctic but "only modest warming for Antarctica". [http://www.realclimate.org/index.php?p=18 RealClimate ] ]
