Key remaining uncertainties relate to the precise magnitude and nature of changes at global, and particularly regional, scales, and especially for extreme events and our ability to simulate and attribute such changes using climate models.

Computer models fail to simulate the magnitude or even the sign of changes of important elements of the climate system, including regional and atmospheric temperatures, precipitation, clouds and winds.

For terrestrial British Columbia, precipitation averages and extremes can be simulated more accurately within individual regions by using gridded downscaling to increase the resolution of both global and regional climate models.

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).

So climate scientists simulate regional changes by zooming in on global models — using the same equations, but solving them for a much larger number of grid points in particular locations.
