I'm off home in a minute, but there appear some differences in levels. Keith and Tim's diagram is the new one that didn't make it to the present IPCC draft. For the other two, yours has 0.12 added to it to correct your base period of 1902-80 (can't remember your exact dates) to 1961-90. For mine we've used a mean and SD calculated by Tim based on April-September average temps from the NH Land series north of 20N. As I say only problem is the level - the curves are similar given that one is a 40 year and one a 50 year filter. We'll work on this more tomorrow.
