[Vision2020] Goddard Institute for Space Studies: Sept. 2011 Ninth Warmest Since 1880: Arctic Warmth Continues

[Paul Rumelhart]

This reminds me of something I wanted to ask.  Polar amplification comes 
out of climate models that make assumptions about GHGs being forcings 
for the climate.  Yet, there doesn't seem to be anything intrinsic to 
polar amplification to tie it specifically to warming from greenhouse 
gases.  Is anyone working on the question of whether or not polar 
amplification would happen if warming was more from natural causes than 
anthropogenic ones?
