Projected Change in Annual Mean Temperature; 2021-2050 relative to 1971-2000
Projected change in annual mean temperature (°F) for the contiguous United States, for 2021–2050 with respect to the reference period of 1971–2000. These are multi-model means using CMIP3 SRES A2, A1B, and B1 scenarios (left column), and CMIP5 RCP8.5, 6.0, 4.5, and 2.6 scenarios (right column). Color with hatching (category 3) indicates that more than 50% of the models show a statistically significant change, and more than 67% agree on the sign of the change (see Section 3).
