I read a book a few years ago about global warming. They said when the ice cap melts, more moisture, will disrupt the heavens and we'll have tornadoes, hurricanes, etc. While I didn't believe in global warming, their predictions ARE coming true about the tornadoes and crappy weather. But, I still wonder if it's really global warming. If we hadn't had global warming for the last 1500 yrs, we'd have ice clear down to Oregon. They also said in the book that the oceans would rise...I haven't seen that happen!!!! I think it's cyclic....and we just FEEL like there's a lot of it happening because we never had the media/internet to inform us of what was happening on the other side of the US (or world). Remember -- we had dust bowl days and all kinds of things happening in the early 1900s and people at the other end of the states had no clue.
