Argument: Atmosphere has responded as expected to human-induced climate change

Issue Report: Is climate change chiefly human-caused?


  • “Temperature Trends in the Lower Atmosphere, Understanding and Reconciling Differences”. Climate Change Science Report (CCSP). SAP 1.1. Executive Summary. – “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 humaninduced 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.”
  • The IPCC Fourth Assessment Report Summary for Policymakers states – “New analyses of balloon-borne and satellite measurements of lower- and mid-tropospheric temperature show warming rates that are similar to those of the surface temperature record and are consistent within their respective uncertainties, largely reconciling a discrepancy noted in the TAR.”
