There are many world renowned scientists and organizations that include a massive amount of research indicating that the earth's temperature has been increasing due to man's activities.  Have you see the satellite pictures showing where there used to be ice or is this information along with all the studies just fiction? What do these hundreds if not thousands of scientists have to gain by fabricating all this?  Do tell me.  Trump has changed his mind on many positions since taking office and I am not saying that is a bad thing.  It's just a shame that he has to be so nasty at times when he disagrees on a subject.  I think I will go with these scientists instead of your degree in science.
