Christy still using his bad data? LOL

CHRISTY is the director of the Earth System Science Center at the University of Alabama-Huntsville and Alabama state climatologist. CHRISTY and fellow University of Alabama professor Roy SPENCER co-authored a 2003 global warming study based on extensive data from weather satellites. Their report, which concluded that the troposphere had not warmed in recent decades, was ultimately found to have significant errors. The New York Times reported that when their miscalculations were taken into account, the data used in their study actually showed warming in the troposphere.

The troposphere should warm faster than the sfc, say the models and basic theory. As indeed it does - unless you're wedded to the multiply-corrected Spencer+CHRISTY version of the MSU series. CHRISTY (naturally enough) features in this section, though he seems to have forgotten the US CCSP report, and the executive summary which he authored says Previously reported discrepancies between the amount of warming near the surface and higher in the atmosphere have been used to challenge the reliability of climate models and the reality of human induced global warming. Specifically, surface data showed substantial global-average warming, while early versions of satellite and radiosonde data showed little or no warming above the surface. This significant discrepancy no longer exists because errors in the satellite and radiosonde data have been identified and corrected. New data sets have also been developed that do not show such discrepancies. See-also previous RC posts.
