I know much more about Peak Oil than about Global Warming, but I know enough about the latter to be able to discern some common errors. There was an article in the Daily Telegraph about a month ago which was not very good in that respect - it was scepticism, but woefully ill-informed.
This seems different. Doubtless there are places where he is wrong, but if his core point is correct, then there is some serious misleading going on. Whilst one of the most effective elements of Al Gore's film was the comparison of scientific assessments of global warming vis-a-vis the reporting of same in newspapers, I can't help but remember the cautionary phrase '100,000 lemmings can't be wrong'. Unanimity is no guarantee of truth.
I'd be interested to see a detailed rebuttal of the article, if anyone comes across one.
UPDATE: George Monbiot here.
