THE WAR ON SCIENCE:

The Coming Ice Age : A true scientific detective story (Betty Friedan, September 1958, Harper's)

THIS is the story of two scientists, who started five years ago -- with a single radiocarbon clue from the ocean bottom and a wild hunch -- to track down one of the earth's great unsolved mysteries: What caused the ancient ice ages? Their search led over many continents and seas, to drowned rivers and abandoned mountain caves, into far-removed branches of science. It took them down through recorded history, from the stone tablets of primitive man to contemporary newspaper headlines.

These two serious, careful scientists -- geophysicist Maurice Ewing, director of Columbia University's Lamont Geological Observatory, and geologist-meteorologist William Donn believe they have finally found the explanation for the giant glaciers, which four times during the past million years have advanced and retreated over the earth. If they are right, the world is now heading into another Ice Age. It will come not as sudden catastrophe, but as the inevitable culmination of a process that has already begun in northern oceans.

As Ewing and Donn read the evidence, an Ice Age will result from a slow warming and rising of the ocean that is now taking place. They believe that this ocean flood -- which may submerge large coastal areas of the eastern United States and western Europe -- is going to melt the ice sheet which has covered the Arctic Ocean through all recorded history. Calculations based on the independent observations of other scientists indicate this melting could begin, within roughly one hundred years.

It is this melting of Arctic ice which Ewing and Donn believe will set off another Ice Age on earth. They predict that it will cause great snows to fall in the north -- perennial unmelting snows which the world has not seen since the last Ice Age thousands of years ago. These snows will make the Arctic glaciers grow again, until their towering height forces them forward. The advance south will be slow, but if it follows the route of previous ice ages, it will encase in ice large parts of North America and Europe. It would, of course, take many centuries for that wall of ice to reach New York and Chicago, London and Paris. But its coming is an inevitable consequence of the cycle which Ewing and Donn believe is now taking place.

Yeah, but this time the climate hysterics are right!
