20 degrees in Florida does not prevent global warming. The earth's temperature can rise 1 degree over a 10 year span and that is a warming trend. Do I think it is something to be upset about?......NO! I think there is evidence of a slight warming trend and I believe it is cyclical, but that's just me. Where the Dems lose me is their exaggeration of causes, most of which are aimed at emissions that fall under EPA guidelines, which we all know are impossible to follow to the letter. If we followed EPA guidelines to a tee, all our factories and plants would have to shut down.
I know I am going to catch heck for this post because I am a conservative, but I go with my gut.
