Though there can be significant differences in regional surface impacts between one SSW event and another, the typical pattern includes changes in sea level pressure resembling the negative phase of the North Atlantic Oscillation (NAO) / Arctic Oscillation (AO), (representing a southward shift in the Atlantic storm track), wetter than average conditions for much of Europe, cold air outbreaks throughout the mid-latitudes, and warmer than average conditions in eastern Canada and subtropical Asia (see figure below, left panel).

Note that I am not saying that warming has not taken place just that it is not global — BEST admits that 30 % of the stations have cooled and that is true of severla of therse long term stations — but that we should concentrate on finding a useful set of temperature trends in regional and zonal areas that reflect the impacts of climate change, as for example the Sahel, and understand the true reasons without assuming carbon dioxide to be the culprit.

Modeled regional and global climate responses to simulated (107, 110, 111) and reconstructed historical land cover changes over the past century (112) and millennium (113) generally agree that anthropogenic deforestation drives biogeophysical cooling at higher latitudes and warming in low latitudes and suggest that biogeochemical impacts tend to exceed biogeophysical effects (113).
