All this bluster just because I had the temerity to post a link to a paper from a well respected, honoured and awarded climatologist who doesn't agree with the consensus view on AGW and CO2 in particular. If I'd posted Joe Bloggs from the Daily Express denounces AGW together with his reasons why, I'd understand. Me thinks you all doth protest too much folks, this isn't a personal battle you know, calm down. There is still much uncertainty over CO2 and the role it plays in AGW, not least the amount of impact it has had; if you don't understand this, think the science is a done deal, no more questions to be asked or research to be done then might I suggest your position is misguided, mis-informed and incomplete - perhaps more reading and research on your part is required before leaping on other members of this forum.Can anyone please tell me where the proof that the rise in Co2 is causing global warming,there seems to no proof ,but we keep on being told there is.
