Some things are just inevitable, TimG.
So please tell me what the difference is between your belief that zero emission technology is economically viaable and my belief that adaptation is a more cost effect way to deal with the consequences of CO2 emissions? I can at least support my view by looking at the costs of various technology options today and extrapolating a bit to take into account incremental improvements. Your view that future tech will magically solve all of the problems has no basis other than blind faith.
Why should anyone take your view seriously? Why is your view any different from a belief that god will save us all?
