These interactive maps show Georgia’s expected climate late in the 21st century (2070-2099). The datasets that generated the maps were developed for the Fourth National Climate Assessment. They combine weighted-mean projections from 32 Global Climate Models included in the Coupled Model Intercomparison Project Phase 5 (CMIP5) and downscale the results using the Localized Constructed Analogs (LOCA) method.
Projections include a business-as-usual high-emissions scenario (RCP85) and a moderately-lower emissions scenario (RCP45). A third, upper-bound, scenario combines data for only the three warmest or three wettest models. Brief explanations of the scenarios and a full listing of the 47 available variables can be found here.
The full datasets include historical climate data (1976-2005) and projections for the short-term (2016-2045), medium-term (2036-2065) and long-term (2070-2099).
The maps show data from the high emission (RCP85) scenario, except for the map that shows the difference in average temperature between the RCP85 scenario and lower-emission RCP45 scenario.
Full-screen versions of these interactive maps are also available:
- Average increase in annual temperature in 2070-2099 with business-as-usual (high emissions)
- Average increase in annual precipitation in 2070-2099 with business-as-usual (high emissions)
- Added number of maximum consecutive dry days in 2070-2099 with business-as-usual (high emissions)
- Added days with temperature over 100 degrees F in 2070-2099 with business-as-usual (high emissions)
- Reduction in average temperature comparing high-emission (RCP85) and lower-emission (RCP45) scenarios.
