But such a graph would be meaningless. All climate scientists (and other scientists) work with anomalies. So the indices are constructed on that basis - that is the variance from a defined base point, and for good reasons. NASA set their 'zero' to be the average climatology from 1951-1980, for reasons to do with the quality of coverage over that timespan, all laid out in the documentation.
1.2C is about right. Probably in the region of 0.8C of that is greenhouse. The IPCC project around +0.2C / decade (though not in a straight line!) for the next few decades.
Cue the argument that such a 'small' change is nothing to worry about ...
