Explore charts, maps and data of observed and projected climate variables for California. The tools show projections for two possible climate futures, one in which emissions peak around 2040 and then decline (RCP 4.5) and another in which emissions continue to rise throughout the 21st century (RCP 8.5). Both futures are considered possible depending on how much action we decide to take. Learn more about working with climate projections on our Resources page.
