Multiply that result by 1.8(=9/5) to get changes in degrees Fahrenheit (deg-F). Best estimate for absolute global mean for 1951-1980 is 14.0 deg-C or 57.2 deg-F, so add that to the temperature change if you want to use an absolute scale (this note applies to global annual means only, J-D and D-N !) Example -- Table Value : 40 change : 0.40 deg-C or 0.72 deg-F abs. scale if global annual mean : 14.40 deg-C or 57.92 deg-F
