Answer 6

Global warming now, global cooling then.........I used to be more liberal, but as I aged I found myself reading more and applying common sense.  The earth goes through temperamental warming/cooling  cycles.  It's been doing it for millions of years.  Can we affect it?  Maybe.  Can we stop it? No.  Don't think that China or America is responsible.  These cycles won't end.  You and I will be long gone, and they will keep on rolling.  Try not to lose sleep over this issue.
