Quote:as well as Global Warming.That is not a theory any more than global cooling, or global spinning are theories. The unknown is what level of CO2 in the atmosphere causes bad things to happen, which is pretty unanswerable and stupid to continue to experiment on ourselves. I am still hopeful that nature has the capacity to reel us back from the brink of disaster, but only a few hundred years will tell.
