2. For each model at each grid point, the mean temperature under the RCP4.5 scenario was calculated for the period of 2036–2065, and the mean temperature for the reference period was calculated for the period of 1986-2015. To calculate the mean values for the reference period, the RCP4.5 scenario data for 2006-2015 were appended to the historical data for 1986-2005, and then the 30-year mean was calculated using the period of 1986-2015.

3. At each grid point, the difference in projected temperature was calculated for 2036–2065 minus 1986–2015.

4. For each model, these data were re-gridded to a common grid.

5. At each grid point, the mean temperature difference was computed by averaging the following models:

ACCESS1-0, ACCESS1-3, bcc-csm1-1, BNU-ESM, CanESM2, CCSM4, CESM1-BGC, CMCC-CMS, CNRM-CM5, CSIRO-Mk3-6-0, FGOALS-g2, GFDL-CM3, GFDL-ESM2G, GFDL-ESM2M, GISS-E2-H-p1, GISS-E2-R-p1, HadGEM2-AO, HadGEM2-ES, inmcm4, IPSL-CM5A-LR, MIROC5, MIROC-ESM, MPI-ESM-LR, MPI-ESM-MR, MRI-CGCM3, NorESM1-M.

6. The mean temperature difference was plotted for grid points in the Contiguous U.S., Alaska, Hawai’i, Puerto Rico, and the U.S. Virgin Islands."^^
