The link is to global lower atmopshere temps for last 30 years. UAH is University Alabama Huntsville. I have no idea if this is accurate. Note that this is not surface temps, and that I recall (but could be wrong) that the upper atmosphere is forecast to cool with surface warming (don't know if that would be upper Troposphere, or stratosphere, or what).

But, looking at this graph, the way I see it there has been warming for the last 15 years, not much before, 1998 is an anomaly/outlier, it has not warmed in the last 5 years or so, and it has cooled during 2007 and early 2008. Theer seem to be occasional sharp drops throughout the 30 years. Will be interesting to see how this one plays out.

I'd like to see an unbiased graph of global surface temperatures (say, from NOAA or NASA), up through late 2008, with some explanation of how it was corrected (for urban heat effects and anything else).
