Lewis makes a couple of potentially interesting points, chief of which concern the magnitude and
uncertainty in the aerosol
forcing I used and the time period over which the calculation is done, and I
address these issues here.
[Response: A similar conclusion to the one cited by Gavin above was reached independently by a panel of scientists (of which I was a member) convened to report on these issues by the National Academy of Sciences last year, resulting
in the NAS report «Radiative
Forcing of Climate Change: Expanding the Concept and
Addressing Uncertainties (2005)».
Part II
addressed uncertainties in external
forcing data sets used
in the attribution studies and the relevant climate model structural
uncertainties.
It also means emissions of other GHGs have to be
addressed to the extent they really do add 40 % to the CO2
forcing, but the
uncertainty is CO2
forcing + 35 % + / - 65 % from aerosols + GHGs
in AR5.
