...dating each ice layer like growth rings on a tree, the scientists have been able to use the oxygen-isotope ratio to chart yearly variations in weather to depths of 300 ft. Beyond that level, the annual record becomes blurred. But it is still clear enough to let scientists distinguish broad climatological trends. Analysis of the layers showed, for example, that the earth's last ice age began some 70,000 years ago and did not end until about 10,000 years ago. The investigators also made some long-range forecasts. Projecting the established weather pattern, they predicted that...
