Alex: aren't you HAPPY that the melting glaciers are the result of a volcanoe? If true, that would mean that global warming is NOT man- made and that we will NOT all die a horrible death like Al Gore wants us to believe. Aren't you excited about the possibility that the concept of man-made catastrophic global warming is all bunk?
