Recently an advocate of AGW posted a graph from Wikipedia that was intended to prove that the surface record was not contaminated by urbanization. Climate models indicate that the troposphere should have warmed 1.3 times faster than the earths surface. The graph shows trends from 1982 - 2004, as listed below.
Surface : +0.187˚C/Decade (BLUE)
UAH : +0.163˚C/Decade (RED)
RSS : +0.239˚C/Decade (GREEN)
The UAH indicates that the surface warmed at a faster rate than the atmosphere, which disproves the CO2 theory. RSS indicates that the atmosphere warmed at 1.278 times faster than the surface which supports the theory, but the RSS correction involves utilizing a climate model to make it's corrections which seems suspicious. And the graph computes the slopes starting at 1982, which also is very suspicious. It seems that if the slopes were computed from 1979 neither would support AGW.
