Just gave a very quick read of "Ordonez, A., S. Martinuzzi, V. C. Radeloff and J. W. Williams, 2014. Combined speeds of climate and land-use change of the conterminous US until 2050. Nature Climate Change 4, 811-816."
Ordonez and colleagues present a short article representing lots of work mapping climate change and land use across the US. They examined where climate change and land use change would affect ecosystem most rapidly as independent and combined effects.
For climate change, the strongest effects will be seen in the Great Plains where there will be no topographic refugia for a warming climate. There will also be high rates of land use change, much of urbanization. So the Plains are screwed. The West appears to have relatively low rates of change for climate and land use. The ne and se US will be mixed.
