claim: UAH atmospheric temperatures prove climate models and / or surface temperature data sets are wrong.
evidence: Globally, most climate models used by the IPCC in preparation of their third assessment in 2007 show a slightly greater warming at the TLT level than at the surface ( 0.03 °C / decade difference ) for 1979–1999 while the GISS trend is +0.161 °C / decade for 1979 to 2012, the lower troposphere trends calculated from satellite data by UAH and RSS are +0.130 °C / decade and +0.206 °C / decade.
