I invite you to read this article from the April 28, 1975 issue of Newsweek. They warned that unless we took drastic measure like artificially melting the artic ice cap, we will face major worldwide problems with crop production and thus food supply. Now that the ice cap is melting all by itself, they warn that unless we take drastic measure, the world will be submerged under water. I am not sure 30 years from now, what would be their warning? Any guess on what drastic measure they would want to ram down your throat with their more-than-conclusive evidence of global warming?
