...Fred peeped out of the tent flap at 4:30 a.m. to find four inches of snow on the ground. Then he slipped on an extra suit of thermal underwear and set out in the dark. In the near-zero temperature, the inlet rimming the camp was layered with ice, and the sand was frozen hard as concrete. Bending like a bloodhound over the maze of snow tracks in the clearing, Fred whispered: "They're moving out of that shintangle [thicket] over there just after sundown." At dusk, as he watched a deer 100 yards off through his binoculars...
...working above the Arctic Circle at a remote encampment 120 miles east of Thule. For several years, they drilled through the 4,500-ft.-thick Greenland icecap, gathering cores, or cylindrical samples, that provide a remarkably accurate record of Greenland's weather. The cores consist of layers of ice, each representing a year's precipitation. They have remained virtually unchanged for centuries. By analyzing these layers, scientists have been able to reconstruct a climatic history that reaches back for 100,000 years...
...water is O18, and water molecules containing the heavy isotope will fall from clouds in the form of rain or snow before those with ordinary oxygen atoms. In colder weather, the isotope falls even more rapidly. Thus, by the time that clouds arrive over the site where the ice cores were taken, the ratio of O18 atoms to ordinary oxygen atoms in the precipitation is lower than usual...
...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...
...Barnett destroy a protest movement by leading a "floatin" in front of a Liberian freighter carrying grain for Royalists in Yemen? Impossible. Will Barnett make a mockery of the Camp aesthetic and win the ice-cold heart of Rosalie by memorizing all the shows of the Ted Mack Original Amateur Hour! Improbable. Might Barnett expiate 400 years of white guilt by joining "a group of young white businessmen who had gathered together to back a Negro clothes designer and a Harlem dress store in a new line of maternity clothes called 'Mother Jumpers'?" Unconscionable. Could Barnett win Rosalie...
