For balance to FC thoughts on global warming let me add.. Yes global warming is taking place.. Like the tide over time it comes and goes.. We can do little to change.. On the separate issue of "pollution" ..yes that is something if 7.2 billion folks would do something "collectively " we could impact.. But you will not stop global warming.. Gore failed to differiate these 2 issues. They should not be blurred. Those promoting carbon tax credits do this ... misleading us to believe that if we stop pollution then global warming will stop... The literature does not support this finding. Yes this site sould not be on this topic. But the data posted earlier needed another perspective. I will not post further on the topic as our time in important. Tpower
