    Abstract:

    The uncertainty in projections of climate change at the end of the 21st Century, due to burning of fossil fuels, is roughly equally due to uncertainty in greenhouse gas emissions and uncertainty in the response of the climate to those emissions. Concerning the latter, it is well known that climate models share a similar global pattern of warming. Here, I will show that the differences in the projections of warming across the models also share a common pattern. The physical significance of this pattern will be explored. The results highlight that most of the uncertainty in regional temperature projections is related to generic, non-local feedback processes. Narrowing the uncertainty in global mean temperature projections will also narrow the uncertainty in regional warming projections almost everywhere on the globe. Implications for numerical downscaling, and for quantifying the uncertainty in climate impacts such as human heat stress, will be discussed.
