...called Count Baltar, a first cousin to Darth Vader, the robots take off in hot pursuit of the survivors of the dozen planets, who are manning a ragtag fleet hovering around the "battlestar" Galactica. The humans are desperately searching for the 13th planet, a lost, legendary human colony called Earth. Lorne Greene is the wise old man in charge, and Dirk Benedict and Richard Hatch play Han Solo and Luke Skywalker . . . oops, Lieut. Starbuck and Captain Apollo. Galactica's version of Artoo Detoo is a robot dog, a "daggit," named Muffit. Unfortunately, the duplicator at Universal Studios, which...
...vitally important to the earth's wellbeing. A key ingredient in photosynthesis-the miraculous process by which green plants grow and produce oxygen-CO2 directly or indirectly sustains all terrestrial life. Now it appears that the gas may carry the potential for trouble as well. Accumulating in the atmosphere at an accelerating rate, carbon dioxide could significantly raise global temperatures by early in the next century and dramatically alter the quality of life. With such a prospect under study, a federal official says: "We have about ten years to come up with an answer...
...density of CO2 increases, the gas acts somewhat like a one-way mirror. Rays of life-giving sunlight can pierce it, heating the surface of the earth. But when this heat is radiated back by the ground in the form of longer infra-red waves, it is screened by the CO2, which absorbs it, thereby raising its own temperature and that of the ground. This so-called greenhouse effect is dependent on the concentration of atmospheric CO2: the greater the amount, the warmer the earth may become...
...projections, atmospheric concentration of CO2 might reach four to eight times that of the pre-industrial level by the year 2150. That, predicts the panel, could produce an increase in the global mean air temperature of more than 6° C (11° F.)-creating climatic conditions that the earth has not seen since the age of the dinosaurs more than 70 million years...
Even if the hike in temperature were smaller-say only a degree or so-the effects might not be minor. Applied year round to the entire earth, such an increase could shift whole forests, grasslands and deserts. At the polar regions, enough ice could melt to elevate sea levels by as much as 5 m (16 ft.). That would eventually inundate low-lying coastal areas round the world, including parts of The Netherlands and the Atlantic seaboard...
