This is a great discussion. We should send it to all of our politicians who (at least seem to) BELIEVE this global warming caused by humans BS. It's great to be among a bunch of like thinkers who know this to be untrue. How can these gasbags make most of the people believe this stuff? Methinks that the dumbing down process in our educational system has succeeded beyond the perpetrators wildest dreams. Just look at how many people think that a train can stop as they pull their SUVs out onto the tracks because whatever they are doing is more important than whatever that train is hauling. OK, off the soapbox.
