Global warming

What with the raging debate about man made global warming and all its derivative industry pro & con, I am still trying to get my head around it, although I must admit that I am growing increasingly weary about the blatantly partisan direction that the debate is taking. Channel 4's The Great Global Warming Swindle takes a refreshingly contrarian position: it not just questions the economics of counter measures (it barely does, in fact), but it goes so far as to question the received wisdom that global warming is scientifically proven (yes, yes ...) to be man made. It offers alternative explanations for unquestioned climatic variability (unsurprisingly, the sun), plus a set of more or less obvious conspiracy theories. Well worth watching for every open minded contrarian.
