Looks like some rather uninformed arguments being put forward here. I would recommend the book 'Skeptical Environmentalist', which covers plenty of what is being debated (and not very well, I hasten to add!) - and more besides..! http://www.amazon.co.uk/Skeptical-Environm...1821&sr=8-1 Global Warming is definitely happening, over the long-run. Anthropogenic Global Warming is also happening, but it seems the jury is still very much out on what the actual / real effect of the AGW is - and how best to deal with it. The above book is written by Bjorn Lomborg, who used to be a member of Greenpeace, but left them. He left as he discovered the organisation was being rather choosy about what / how data was represented and interpreted, in much the same way as business / governments do. This in itself came about as, whilst Lomborg was - in his words - an 'old, left-wing style member of Greenpeace', some bloke argued against the doomsday environmental scenarios that were being bandied about. As an old-school style environmentalist - and a rather good statistician - Lomborg got so left trouser leged off about this that he decided to reanalyse the base data that the accumulated propaganda (on both sides of the argument) had built towards to prove this guy wrong. He expected to find that the other guy was twisting data to fit his right-wing capitalist agenda. But what he found was that - although the guy had some errors - a large part of what this other guy was saying was valid and correct. This made Lomborg question more 'accepted' environmental approaches and views and he started to see that the old fashioned environmentalism was as wrong as the arch-capitalist 'finger-in-the-ears-and-la-la-la' approach! Out of this he did more work and - having left Greenpeace, amongst other things wrote the above book to reanalyse what is going on in the world, environmentally. He is not an anti or pro environmentalist. He is not anti or pro GW / AGW. What he is the best type of commentator: not being lazy and looking at and understanding the data and hoping to guide what the best way is to understand the issues, the underlying causes and the best way to act (or not) to come to the best conclusion. Buy it, read it, enjoy it but most of all, GET EDUCATED!
