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
Best Case – January 2080-2099
Moderate Case – January 2080-2099
Worst Case – January 2080-2099
Best Case – July 2080-2099
Moderate Case – July 2080-2099
Worst Case – July 2080-2099
