Divide by 100 to get changes in degrees Centigrade. Multiply that result by 1.8(=9/5) to get changes in degrees Fahrenheit. Best estimate for absolute global mean for 1951-1980 is 14C = 57.2F, 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 : .40C or .72F abs. scale if global annual mean : 14.40C or 57.92F
