Environmentalists first predicted impending climate disaster in the 1970s, but they didn’t call it global warming. Back then, it was “Global Cooling” that would end life on earth as we knew it. The smog of industrial pollutants was blocking out sunlight so severely, we were warned, that our planet would enter a new ice age unless we acted quickly. Magazine covers featured pictures of snowball earth.
In the eighties, we cleaned up our air, the threatened the ice age did not occur, and thousands of people with time on their hands and seeking purpose in life had discovered that they could make a career out of disaster prophecy. Thus, it was time for a new catastrophe: “Global Warming” Well, maybe not so new. Same villain: us and our machines. Same victim: our delicate planet earth. Same threat: the end of life as we know it. Only the predicted temperature had changed.
