I woke up one day to read that the 'debate was over' on AGW or man-made global warming. This for me was a surprise, because I had not followed the debate. As a geologist familiar with complex systems over time, I wondered how such a statement could be true. So I have spent the last 18 months reading my way into the topic. This includes the IPCC reports, and not just the SPM. So far,I have failed to identify the source of the evidence or research which clearly links the rise in CO2 in this century with an increase in temperatures. Furthermore, many aspects of modern civilization contribute to changes in ait temperature but CO2 has been singled out as the only one to be mitigated. This implies that CO2 is the only factor we need to look at, a concept I find difficult knowing the complexity of the planet over geological time. From my reading, it is not clear if CO2 derived from man-made sources is significant, based on the IPCC date itself. In view of the certainty expressed by those who espouse the view that AGW is '90% certain' I would appreciate guidance in where I can find this information. Unfortunately, with most experts arguing for AGW, asking this question seems to be treated as heresy, rather than a sound scientific request. I hope you can help me in this matter. Cheers Christian Hi Stephen,
