Tom,

If you understood what he was alluding to, why did you deliberately misstate 
his position?

The paper is wrong in its predictions because he he uses a climate sensitivity 
of 4.2 degrees for doubling of CO2 rather than ~3 degrees which most climate 
scientists, including him, now believe is the correct value (the science has 
progressed since then).

Are you saying you don't believe in climate change because has been proved to 
only be extremely bad not catastrophic, therefore it can't be real??

The papers predictions also don't match observed temperatures because the 
prior conditions in the paper (concentrations of non-CO2 greenhouse gasses, 
esp CFCs) don't match current conditions. His predictions of future levels of 
CFCs in the atmosphere were too high.
