The mean of the various GCM models is .5 degree C higher than the mean of the current values in NASA table LOTI, even with their inflated values. The GCM models also have the increase as a more geometric increase (more and more CO2) so the separation between the models and the actual values is growing every year now. My model shows this growing separation will continue until 2035 such that it will be over 1.0 degrees C by then.
