When I was in elementary school all the text books talked about how, based on temperature trends, we were slowly descending into a new ice age. The past decade it's been all about how we are doomed to a fiery death at the hands of global warming. Now we are experiencing the coldest, most snow-laden winter since 1966. Even Red China is suffering it's coldest winter in a century. And how about those quickly melting ice caps that last year were thinner than they've ever been (at least thinner than they've been since 1972 when they started taking measurements)? Well, they've gained their weight back. Makes ya wonder.
A great site, though at times a bit on the heady side, is Junk Science.
