I have studied this issue for many years, reading everything I can find on the subject, including all the IPCC reports (not just the executive summaries). I have yet to come across any credible evidence that increasing atmospheric CO2, man-made or otherwise, is causing global warming. To the contrary, all of the research-backed theories that seem to explain past climate changes have nothing to do with CO2. Since you all seem to be convinced that it is, maybe you can point me to some research to enlighten me. So far, all this hype appears, in my view, to be based on computer models that are seriously flawed.
With a science and mathmatics background, I work in the Environmental Protection field. There are plenty of issues such as stormwater management, erosion, use of pesticides (etc,), and poor development planning that need our attention. So to waste time and huge amounts of resources on this doomsday scenario seems rather counter productive .
