...lives in Southern California, an even deadlier natural disaster was advancing slowly but inexorably south from Canada into the U.S. By midweek a huge mass of frigid arctic air had practically paralyzed much of the Midwest and East. Temperatures in dozens of cities dropped to all-time lows: -22 degreesF in Pittsburgh; -25 degrees in Akron, Ohio, and Clarksburg, West Virginia; -27 degrees in Indianapolis, Indiana. Chicago schools closed because of cold weather for the first time in history, Federal Government offices shut down in Washington, and East Coast cities narrowly escaped widespread power outages as overburdened electric utilities struggled...
...colleagues first stunned the research community six years ago by showing that a compound containing the exotic element yttrium could become a superconductor at 98 degrees on the Kelvin scale favored by physicists (that's a not-so-balmy -283 degreesF). That record, broken repeatedly, is now as outdated as the 19-foot pole vault, and last month the contest heated up again. First Chu announced in the journal Nature that a mercury-based compound could superconduct at 153 degreesK (-184 degreesF), a startling 20 degrees higher than the old standard. He got that result by subjecting the material...
Inglis admitted to TIME, however, that some aspects of the test might have enhanced the results and made it easier for the interceptor to find its target. The warhead, for example, was preheated before launch to 100 degreesF to provide a clearer infrared signature. The target warhead also carried explosives to increase the detonation and thus assist ground observations. Says a congressional staff member: "Either could have served to skew the tests...
...wrong. According to two articles in last week's Nature, deep holes drilled into the ancient ice of Greenland have brought up evidence of sudden, dramatic swings in climate during the last interglacial period, about 120,000 years ago. Several times, average global temperatures dropped as much as 25 degreesF, plunging the planet back into ice-age conditions, and stayed there for tens or hundreds of years before recovering. And the changes happened not over centuries, as scientists would have predicted, but in as little as a decade. The tranquillity of recent centuries may be a climatic fluke...
...ominous sign: normal temperatures during the last interglacial epoch were about 4 degreesF warmer than they are this time around, and levels of carbon dioxide in the atmosphere were significantly higher. As humans pump more and more CO2 into the air and temperatures rise, the planet will approach the state it was in back then. And if those conditions tend to be inherently unstable -- an idea scientists consider plausible -- people may someday look back on the early 1990s as an idyllic time when the weather was benign...
