Compare Regional Climate Projections Side-by-side
Use the popup menus along the top edge of this interactive (below) to choose a pair of maps to view side-by-side. For example, try comparing:
- temperature change in North America vs. precipitation change in North America
- temperature change in South America as compared to temperature change in Africa

These maps depict projections of future climate in various regions of the world. You may choose from eight different regions, and can display either changes in temperature or changes in precipitation.
These projections represent averages from 21 different climate models. They show how much change is expected near the end of the 21st century as compared to late 20th century values. Specifically, the maps show the projected average values for the years 2080 to 2099 as compared to the average values a century earlier (1980 to 1999).
- The maps showing temperature have a scale running from -1° C. (that is, a decrease in temperature of 1°) to +10° C.
- The maps showing precipitation have a scale running from -50% (a 50% decrease in precipitation) to 50% (a 50% increase in precipitation).
