...threat of the "greenhouse effect," the possibility that all-out burning of coal would pour so much carbon dioxide into the air as to keep heat from escaping out of the atmosphere into space. Theoretical consequences that some scientists like to cite: warming of the earth, melting of the polar ice caps, flooding of the world's seacoast cities. In fact, there is no known way of producing energy without some environmental danger...
...game, Sue St. Louis went behind the goal and whipped a pass out to fellow attackman, Ellen Seidler, who quickly fired it into the goal for the first tally of the contest. St. Louis followed Seidler's lead moments later when she stuffed the ball past the bewildered Polar Bear goalie...

...most curious of all these major moons is the innermost, lo (pronounced eye-oh). Roughly the size of the earth's own moon, it has reddish polar caps, a yellowish sodium cloud cover and a strange surface chemistry that may be a consequence of intense radiation bombardment. On its closest approach, Voyager will come within 18,800 km (11,650 miles) of this mysterious moon. Then, as Voyager sweeps away, its instruments will get glimpses of the other Jovian moons, perhaps even a tiny 14th moon, which was spotted several years...
Indeed, Armageddon is something of a growth industry. In an avalanche of recent books, polar caps melt, a new ice age begins, the oceans disappear, the ozone level is destroyed, terrorists touch off a nuclear war, astronauts bring back a deadly Andromeda Strain. Destruction may also come from a maddened god (Gore Vidal's Kalki). Or in an unending snowstorm (George Stone's Blizzard). Or from the scorching "greenhouse effect" of too much CO2 in the atmosphere (Arthur Herzog's Heat). Or through global political disintegration (The Third World War: August 1985 by a group of English...
