Since the Stern report I have started to read up on the subject in some detail. Of course I am not a climate scientist, but can read and have spent much time seeking, downloading and reading papers on the subject, both popular and more scientific.
Also having a general interest in geology I have come to question the current authodoxy on Anthropogenic Global Warming. The Stern report was a serious shot across the bows of anybody who does not realise that Governments can see a great opportunity to raise taxes even more than the current daylight robbery.
This documentary, whilst flawed, does contribute much more to the debate and thought process than sadly the David Attenborough BBC presentation from 2006 (which I have also boaught and re-watched).
At least TGGWS presents some facts all be it rather controversially.
As for those commentators who claim that the program has been discredited by the Ofcom report of July 2008, please feel free to read that report (as I have) and you will find Ofcom makes no claim at any stage of the 60 odd pages devoted to TGGWS, about the science, only critising the fact that the program makers did not give Carl Wunsh or David King enough time to respond. Most of the complaints were rejected.
Clearly the whole question has become a religious/idealogical crusade for many people and this results in sad and vitriolic ad-hominem attacks on people. This is NOT the scientific way, but the self righteous way of zealots and idealoues. If people would stick to the science and discuss the subject accordngly the only conclusion so far can be "Case not proven, much more reasearch needed".
This documentary at least makes some popular contribution to countering the religious tone of those asserting that debate is over.
