I think that debate of any null hypothesis less rigorous than the claim that «any
human influence on climate is more
catastrophic than any possible alternative action man might take» will ultimately be used by the CAGW forces as if that
catastrophic version were indeed the one that had been debated and not falsified.
Most global warming skeptics believe that
humans have some measurable impact
on global temperatures and the
climate, but that natural
climate forces, over longer periods, will overwhelm the
human influence... in addition, skeptics believe that the
human influence will not result in the hysterical
catastrophic climate disasters presented by doomsday pundits...
