Global Warmest defector says, "No smoking hot spot"

So to my eye - without running the actual regression here mathematically - it looks like the latter period is roughly 0.2 C higher in temp than the earlier period. A "step", if you will. Sorry if I'm not explaining myself well.

I see what you're saying. It seems like a matter of interpretation. I don't think we have enough data to conclude definitively one way or the other so I'm not going to say you're wrong. Ok? My bigger problem with these graphs is that they are not global. The long term temperature increase is more evident in the global plots.

Fair enough - a longer record would be better, but we have what we have, and 30 years is not bad.

As for it not being global, the graphs exclude primarily the Antarctic (stop at 70 degrees south latitude). As may know, on the surface at least the Antarctic has actually cooled over this timespan. So if anything, inclusion of that region might further reduce any temperature anomalies, rather than increase them. But I'd have to research it to say for sure.
