Description: Layer shows the historical and projected growing degree days (GDD), a measure of heat accumulation in plants, which measures the cumulative seasonal warming above a base temperature of 50°F. The figure compares watershed averages for historical conditions (1970 - 1999) and the projected change for current generation of climate models, all in units of °F-days. Two time periods are considered: the 2050s (2040 - 2069) and the 2080s (2070 - 2099), based on two greenhouse gas scenarios: one low (RCP 4.5) and one high (RCP 8.5). Dark green shading on the historical map indicates areas with the highest average GDD. Projected increases in growing degree days are depicted by the beige to dark green shading. Figure created by Robert Norheim, Climate Impacts Group, based on the CMIP5 projections used in the IPCC 2013 report. Data source: Mote et al. 2015.
