In 1970s, there was "global cooling" consensus among scientists that triggered governments to do something about it or we'll live in the new ice age. One of those alarmist predicted that 1 billion people will die in a coming new ice age by 2020. Today, there is consensus among scientists about "global warming", and the same guy who predicted "then global cooling", urges immediate passage of the Obama administration's proposed cap-and-trade legislation to control carbon emissions before it is too late to save the planet from "global warming". Today, that guy, John Holdren, is working in the White House as Obama's science czar. Well, OK... 40 years ago was global cooling, then 10 years ago it changed to global warming. But, its getting bit confusing, since all those "global warming" screamers, are really looking very stupid these days. What happened to global warming?
