#Divide by 100 to get changes in degrees Celsius (deg-C). #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 !) #
