Simulated difference in the mean annual number of days with a minimum temperature less than 32°F
Simulated difference in the mean annual number of days with a minimum temperature less than 32°F (Tmin < 32°F) for the contiguous United States, for the 2041-2070 time period with respect to the reference period of 1980-2000 (top). Color only (category 1) indicates that less than 50% of the models show a statistically significant change in the number of days. Color with hatching (category 3) indicates that more than 50% of the models show a statistically significant change in the number of days, and more than 67% agree on the sign of the change (see text) (see text). Mean annual number of days with Tmin < 32°F for the 1980-2000 reference period (bottom left). Simulated mean annual number of days with Tmin < 32°F for the 2041-2070 future time period (bottom right). These are multi-model means from 8 NARCCAP regional climate simulations for the high (A2) emissions scenario. Changes are downward everywhere. Decreases are largest in the western U.S. and are smallest in the far southeast.
