If I may ask, what physical mechanisms are behind your prediction? Why do you think it'll warm 0.75 C/century?
Empirical evidence more than anything else.

I make a habit of throwing the NOAA numbers into a spreadsheet every month to calculate a variety of averages, as well as velocity, acceleration and jerk. I see acceleration and jerk looking very much like sine waves, I see velocity as positive but relatively flat, and I see position looking a lot like a step function.

With the derivatives holding steady over time, I see no reason to expect temperature increase to vary from its (recent) historical norm.
