Read the comments too.  There is a lively debate that offers counterpoints from those who still believe in "climate change."  One commenter had a question that I have asked for years: What caused the warming that ended the glacial period 10,000 years ago?  Certainly wasn't man's use of carbon fuels.  Maybe warming and cooling is a natural cycle?
