The first column I ever wrote, 39 years ago, was titled “The Profits of Doom.” This was long before Al Gore made millions of dollars promoting global-warming hysteria. Back in 1970, the prevailing hysteria was the threat of a new ice age — promoted by some of the same environmentalists who are promoting global-warming hysteria today. -Thomas Sowell, Dec. 2016

“Scientists have solid experimental and theoretical evidence to support…the following predictions: In a decade, urban dwellers will have to wear gas masks to survive air pollution…by 1985 air pollution will have reduced the amount of sunlight reaching earth by one half….” -Life Magazine, January 1970

"Global warming activists have claimed for years that the 1970s global cooling scare never existed. They have tried to erase the inconvenient history which ironically blamed extreme weather like tornadoes, droughts, record cold and blizzards on global cooling.” -Marc Morano

The suspicion that winters are getting colder is no longer merely a suspi­cion among climatologists. Over the last 30 years permanent snow on Baffin Island in Canada has expanded. Pack ice around Iceland in the winter is increasing and becoming a serious hazard to navigation. Warmth-loving armadillos that mi­grated northward in the first half of this century are now retreating southward toward Texas and Oklahoma.

  If all indications are correct, worse is yet to come. Judging by what has happened in the past, it may very well get cold enough to allow great glaciers thousands of feet thick to cover North America as far south as Long Island, burying the highest peaks of the White Mountains and Adirondacks.
