Climate models generally say that surface warming on the Earth from greenhouse gasses should be greater at the poles than at the tropics. This is called "polar amplification." I don't now if the models originally said this, or if it was observed that the poles were warming more so it was thereafter built into the models, but that's what they say now. This amplification is due in part to how climate forcings around the globe interact with each other, and in part due to hypothesized positive feedback effects at the poles.

Why is Land Use/Land Cover Change a First-Order Climate Forcing?

Originally posted on August 5, 2005.
As recognized by the National Research Council in 2005, land-use/land-cover change is a first-order climate forcing. However, its role as a regional and global climate influence is not widely recognized, except as it effects the atmospheric concentration of carbon dioxide and the global average surface albedo. In the summary figure from the IPCC Statement for Policymakers (see Figure ES-2 here), in terms of the global mean radiative forcing, only albedo effects of land use/land cover change are identified.
