Another risky experiment with the oceans may have already been tried inadvertently. The temperature of the earth's surface depends to a considerable extent on the atmosphere's small content of carbon dioxide (about .03%), which permits short-wave sunlight to pass but impedes the escape of longer heat waves into space -the so-called '"greenhouse" effect. Since 1860 modern man's furnaces and auto exhausts have spewed out 360 billion tons of carbon dioxide. Warns Revelle: "By 2005 we will have added to the atmosphere some 1,700 billion tons of carbon dioxide-about...
...Centigrade. "Southern California might dry up completely if the temperature rose in the way we think it might-making it an impossible place to live, rather than almost impossible the way it is now." The ocean will also grow warmer, and will be forced to release dissolved carbon dioxide to the atmosphere. This will increase the greenhouse effect. At some point in this chain reaction, the Antarctic icecap will melt, adding enough water to the ocean to drown nearly all of the earth's great cities...
...most important basic improvements in incandescent lamps since Thomas Edison." The pencil-shaped tube lasts twice as long and is one two-hundredth the size of a standard industrial lighting lamp, does not grow dim throughout its life. Iodine vapor in the bulb prevents the formation of blackening carbon on the inside; the lamp's high operating temperature incinerates dirt that touches the outside. Because of their small size, the new lamps can be used to throw exact lighting patterns for show windows, building facades, sports fields, airports. They will permit development of smaller, more effective lighting fixtures...
When lectures came on Saturdays-during which Orthodox Jews are forbidden to work, ride in a vehicle or talk on the phone-Abe would have a friend put a sheet of carbon paper under his lecture notes and hope he remembered to use a ballpoint pen. Sabbath restrictions begin on Friday night, just before sundown, and on occasional Fridays only a lucky break in the traffic has saved him from having to abandon his 1952 De Soto and walk the rest of the way home. On Saturdays Abe was not on duty, but sometimes, to follow...
...TRADE POLICY is being stiffened by Commerce Department, which approved only $6,626,960 of $21.8 million in applications for Soviet-bloc exports during first quarter this year v. $10,213,000 in last quarter of 1958 out of $16 million in applications. Among items banned: polyethylene, carbon-welded pipeline, stainless steel...
