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?<br>
