Simply looking at raw temperature and CO$_2$ data over the past 150 years gives a transient response of roughly 2 K per doubling, in good agreement with IPCC conclusions based on far more extensive analysis. The 0.58 K of Ref. 1 is very unlikely.4 pages, 1 figure: response to Physics and Society, July 2008 issueAtmospheric and Oceanic Physicstext
