Just one comment: You compare HADCRUT3 and the satellite record, but the graph on WFT you point to is actually using WTI - that's my average of all four temperature sources and hence includes HADCRUT3 (and GISTEMP) already. Also, WTI is rebased to the satellite baseline, so you're actually showing the small baseline difference (0.15K), which actually makes it look *more* different than it is! I think the fairest comparison is probably with RSS (with baseline adjustment): http://www.woodfortrees.org/plot/rss/plot/hadcrut3vgl/from:1979/offset:-0.15 which makes them look even more identical. Which means, as you say, whatever else is/was going on at CRU, significant changes to the global trend over the last 30 years isn't one of them. Best wishes Paul P.S. That's one of my favourite cartoons, too :-) Hi,
