In every case we arrive at this same climate sensitivity range of 2 to 4.5 °C, and the most likely value is 3 °C for a doubling of atmospheric CO2. (skepticalscience.com)
Curry's evidence to support that assertion boiled down to arguing of a supposed «lack of warming since 1998», discrepancies between models and observations during that time, a lower climate sensitivity range in the 2014 than the 2007 IPCC report, and the fact that Antarctic sea ice extent has increased.

Most GCM equilibrium climate sensitivities range between 2 and 4.5 °C (average 3.2 °C in GCMs used in IPCC AR5). (skepticalscience.com)
