Jones, I think your post was spot on. If one looks at the geologic record there is evidence that there are several stable atmospheric thermal states signposted by different levels of atmospheric CO2. It is what happens to conditions for life during the changeover periods that concerns me. You pinpoint the dangers of runaway climate change accurately and it is precisely this danger which seems to be discounted at Government levels, inasmuch as an argument they advance is the "we must delay until the science is certain" one. As I am sure you appreciate, this is an insane risk. By the time the final verdict as to whether humans can definitively screw up the climate is in, it will be much too late to do anything about it. Putting excess levels of sequestered carbon from fossil fuels back into the atmosphere is experimenting with the climate plain and simple. We cannot afford to complete the experiment to see what happens because the consequences of doing so could be catastrophic. We cannot wait for the verdict of science - we need STRATEGY now. I have long held the view that cold fusion (or Blacklightpower etc) holds out great hope because, frankly, humanity en masse seems too stupid to take the necessary action for itself.
