Satellite measurements of warming in the troposphere
So where does that leave us? An
"Executive Summary" by the U.S. Climate Change Science Program, co-authored by John Christy of UAH concludes:
"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. This significant discrepancy no longer exists because errors in the satellite and radiosonde data have been identified and corrected. While these data are consistent with the results from climate models at the global scale, discrepancies in the tropics remain to be resolved.
This difference between models and observations may arise from errors that are common to all models, from errors in the observational data sets, or from a combination of these factors. The second explanation is favored, but the issue is still open."
In other words, according to UAH, satellite measurements match the models apart from in the tropics. This error is most likely due to data errors. According to RSS, satellites are in good agreement with models.
Well, whatever the underlying cause, the mistake was on the part of the UAH team, and when corrected, their data showed what everybody else's data did.
