This is not a forum for scientific debate. It cannot be while it is hijacked by lunatics who argue that Margaret Thatcher is part of a Marxist conspiracy, and while people can write nonsense like "not one single number or graph offered for review", while rejecting the very possibility that any evidence offered by the scientific community might be real.

As for Burt Rutan, I wouldn't want to fly in an aeroplane designed by someone who's expertise was in climatology, so why should I take his opinion on the subject as of any significance? Every so often the denialists dig up a list of 'scientists' or 'famous people' supposedly supporting their position but few or none these people have any expertise in the subject being discussed. If there is to be a debate on the issue, it needs to be conducted within the relevant scientific community, as science, rather than used as a political football by the wilfully ignorant, the pushers of deranged conspiracy theories, and clueless anti-intellectuals incapable of rational debate.

I see also that MadBlaster has openly declared that he is trolling - I look forward to seeing him permanently blocked from the forum.
