1. Global Circulation Model Predictions of Future Temperatures Maps compiled from the IPCC DDC web tool that allows access to GCM modeling resultsIPCC DDC web tool NASA’s GISS ER model used for all simulations Temperature anomalies presented as difference between late 21 st 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

2. Best Case – January 2080-2099

3. Moderate Case – January 2080-2099

4. Worst Case – January 2080-2099

5. Best Case – July 2080-2099

6. Moderate Case – July 2080-2099

7. Worst Case – July 2080-2099
