1. Global Circulation Model Predictions of Future Temperatures • Maps compiled from the IPCC DDC web tool that allows access to GCM modeling results • NASA’s GISS ER model used for all simulations • Temperature anomalies presented as difference between late 21st century temperatures (2080-2099 average) and the 1961-1990 30-year average baseline. • IPCC SRES Scenarios presented as: • Worst case (A2) • Moderate case (A1B) • Best case (B1) • Note – other scenarios can be found that give worse “worst” case and better “best” case predictions, but the ones chosen here are commonly used
