There's ZERO doubt by me that the Earth is changing . Thing is, it always has. You can see the puzzle pieces that are Africa and South America. I don't doubt global warming either. It HAD to warm up from 42 years ago. Because if you recall, back then, many were calling for the next Ice Age. My late Brother used to scare the hell outta me with that. It was COOOOLD too! Even here in Jacksonville, I recall MANY MANY freezes in the mid to late 70s. Saw my first snow here , in 4th grade...Jan 1977. I was more accustomed to cold back in those days because I LIVED outside, like most kids of the 70s.
