Where: Mesa Lab, Main Seminar Room.
Future climate change at local and regional scales will result from a combination of human and natural factors. In this talk I show that unpredictable, internally generated climate fluctuations make a substantial contribution to climate trends projected for the next 50 years over North America and Europe. Results are based on large ensembles of climate change integrations with the Community Earth System Model (CESM). I also will show that the large-scale atmospheric circulation is responsible for much of the diversity in climate change projections across the individual ensemble members. I will conclude by discussing some implications of the results for model validation, inter-model comparisons, and interpretation of observed climate trends.
