Eli Rabett January 26, 2014 at 9:48 pm Angech, you are completely wrong,
amplified polar warming has been a major area of study for at least twenty years as all the IPCC reports show
Not exact matches
It is not that the
polar regions are
amplifying the
warming «going on» at lower latitudes, it is that any
warming going on AT THE POLES is
amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more
warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which
amplify climate change at high northern latitudes...»

The findings reinforce suggestions that strong positive ice — temperature feedbacks have emerged in the Arctic15, increasing the chances of further rapid
warming and sea ice loss, and will probably affect
polar ecosystems, ice - sheet mass balance and human activities in the Arctic...» *** This is the heart of
polar amplification and has very little to do with your stated defintion of
amplifying the effects of
warming going on at lower latitudes.
But the models fail to capture the
polar -
amplified cooling in the Arctic from 1945 to 1975 (upper right - hand graph), and they definitely do not show the
polar -
amplified warming that occurred from 1914 to 1945 (lower left - hand graph).
«In this condition, the ice sheet will continue to absorb more solar energy in a self - reinforcing feedback loop that
amplifies the effect of
warming,» wrote Ohio State
polar researcher Jason Box on the meltfactor.org blog.
As can be seen, there has been a cooling trend - granted, a very tiny -0.04 °C / century, but it remains far removed from the IPCC's unicorn science of «
amplified» and dangerous
polar warming.
The IPCC's climate science has long claimed that human CO2 emissions are producing an accelerated global
warming, with a «runaway»
warming trend, which is then being
amplified in the north and south
polar extremes.
Climate change signals are
amplified in
polar regions and indicators, such as the collapse of ice shelves and melting of sea ice, have raised public awareness of the consequences of a
warming world.
The research explains that there is an «
amplifying feedback» as
polar ice melts, because as more freshwater enters the ocean, it traps
warmer sea water, which melts more ice.
