After spending as long as I had available looking at the sources you cite, I have to say I am shocked and surprised that the programme appears to have faked one of the graphs used to make the case.

I haven't found anthing showing fakery in the other material so obviously, but it does throw doubt on the accuracy of other information put forward.

OTOH I had been sceptical about some of the claims about human effects on climate previously, though my best guess was that the actual effect of man was less than widely claimed, not that it was completely insignificant.
