...winter is through. At week's end, temperatures were rising in some regions, but the scientists and computers at the National Atmospheric and Oceanic Administration were confidently predicting that the frigid weather would continue. The chilling pronouncement of Dr. J. Murray Mitchell Jr., NAOA'S senior climatologist: "The forecast is for no change." And spring may indeed be a little late this year-the year when a real old-fashioned winter gripped the U.S., and held...
...Whatever the cause of current weather patterns, they cannot yet be related to any of the long-range cooling -or warming-trends foreseen by scientific Cassandras. Says George Kukla, a climatologist at Columbia University's Lamont-Doherty Geological Observatory: "Just because we can't get our cars started, are suffering from frostbite, and have a few feet of snow in our driveways, we should not start worrying about an Ice Age." Among scientists who fear that significant worldwide climatic changes have already begun, there are those who believe that another Ice Age is not far ahead-as well...
...Climatologists admit that they really do not know. A substantial number believe the earth is undergoing a cooling trend and is returning to the conditions of the "Little Ice Age"-the generally cold, damp weather that prevailed from around 1600 to 1850. British Climatologist Hubert Lamb believes the change is cyclical, occurring every 200 years or so. Reid Bryson of the University of Wisconsin and many others blame the earth's cooling on an increase of dust particles in the atmosphere; the particles act like tiny mirrors, reflecting back some of the sunlight sinking the atmosphere and depriving...
There is some evidence that the earth had cooled down-at least temporarily-in the 1950s and 1960s. In 1972, according to German Climatologist Horst Dronia, the atmosphere in the Northern Hemisphere was one full degree centigrade colder than in 1949. But there have been indications of a slight warming since then. If the cooling-theory school is correct, however, the prospects for man are chilling. A global average temperature drop of only 1° could shorten the growing seasons in the temperate zones by a critical week or more and reduce food supplies. Increased heating requirements would...
...learn more about these fluctuations, an international consortium of scientists is compiling a record of the earth's climate. Climatologist Lamb and his colleagues have assembled an accurate historical record of the seasons going back as far as 1400 A.D.-based on parish registers, government documents, monastery records, and such physical evidence as sediment deposits in lakes and growth rings in trees. Says Lamb: "The more we know about cycles of the past, the better we can work with the highly detailed and sophisticated observations we have of our weather today." Geophysicist Willi Dansgaard of the University of Copenhagen...
