I'm tired of reading so-called "mainstream" publications write articles as if man-caused global warming IS happening and how we're all destroying the earth (especially "Big Oil") etc etc. It has gotten almost comical in the way they go about writing as if it is not even something debateable. National Geograhic is one of those publications. Here in Arizona, we're in the midst of record low temperatures right now.. highs in the Phoenix areas barely making the mid-40's, and records being set for LOWS, since the 1980's. Following the way the libs do things, I guess we should claim this is GLOBAL COOLING and due to mankind we're now entering an ICE AGE??
