Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences

Description:

This Synthesis and Assessment Product is an important revision to the conclusions of earlier reports from the U.S. National Research Council and the Intergovernmental Panel on Climate Change. 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.
This Synthesis and Assessment Product is an important revision to the
conclusions of earlier reports from the U.S. National Research Council and the Intergovernmental Panel on Climate Change. For recent decades, all
current atmospheric data sets now show global-average warming that is
similar to the surface warming. While these data are consistent with the
results from climate models at the global scale, discrepancies in the tropics
remain to be resolved. Nevertheless, the most recent observational and
model evidence has increased confidence in our understanding of observed
climatic changes and their causes.
