I was in my mid-thirties, and remember the magazines hyperbolic predictions well. I also remember that the scientists who said we might trigger a new ice age were basing that opinion on the amount of pollution we were putting into the atmosphere, and the fact that it was reflecting sunlight. However, we cleaned that up, and then saw the rapid warming we are seeing today. In 1975, the PNAS had an article that addressed this. What the thrust of the article was that we had too little understanding of the climate to make accurate predictions. However, they also added that the majority of the scientists thought the warming from the increasing GHGs was going to be the problem. By 1981, Dr. James Hansen definitely proved the problem was going to be warming in his seminal article concerning the observed affects of GHGs in the atmosphere.I was a teenager in the early 1970's and I clearly remember seeing and reading the magazines about scientific predictions of global freezing wiping out humanity.
Scientists were calling it the new Ice Age. ...
