Energy Bill

Let me make the record absolutely clear. I said that during the 4 billion year history of the planet there have been much greater changes in climate than anything that is likely to result from a 50% increase in greenhouse gas concentrations, but that those changes took place before there were human beings, which are one of the most recently arrived species. If we are to support life for 7 billion going on 9 billion human beings in the style to which we have rapidly become accustomed and to which many still aspire, the one absolute precondition is climate stability.
