Wood for Trees is great! I didn't know about that before. (you say it's an average, but then use mean in the equation, that's a significant distinction)
UAH and RSS measure lower troposphere, while GISS and HADCRUT measure surface temperatures. I'm usually more interested in the temperatures in the first 10 feet of atmosphere rather than the first 10 miles of atmosphere (of course, I don't make climate models). HADCRUT4 is a different model of the same source data that HADCRUT3 uses and in theory should be more accurate.
In any case, you've got the hang of it now. By selecting a convenient data source, one can make many creative and not inaccurate statements.
- glenra 13y agoBy the way, when skeptics say there's been "no warming for the last decade", they often mean this: http://www.woodfortrees.org/plot/wti/last:120/plot/wti/last:120/trend http://www.woodfortrees.org/plot/wti/last:120/plot/wti/last:... That one works even if you use GISS - the trend for the last ten years is cooling. (The trend over several other recent periods is "warming, but not very much".) Note: the way I plotted "the last ten years" was to plot the last 120 monthly samples. The WRONG way to do that is to specify a "From" year and plot to the current day, because the resulting chart wouldn't start and end on the same month.
