Atomic dust clouds may have caused the recurrent ice ages in the past, Donald H. Menzel, Professor of Astrophysics, reported Saturday to the American Association for the Advancement of Sciences...
...long-range radiation rays, says Menzel, which usually fly off from the earth, would be stopped by the cloud and retained. Thus the weather would be come warmer, the proper weather for an ice age. More water would evaporate from the earth and fall at the poles as snow, compress itself into ice and start moving as a glacier...
...claims Menzel, the weather would have to be just right. If it became too cold, then too little snow would fall to form ice. On the other hand, a spell of unusually warm weather would melt the ice packs...
Professor Menzel continues to point out that the hypothetical dust cloud which enveloped the earth was thicker at some places than at others. When the world passed through a thick mass of dust, the earth experienced fairly warm weather and the tropics probably flourished. Then as the planet passed into thinner areas, the earth would grow cold and led packs formed...
