Probably, in times of great warmth even the Antartic and Arctic region flourished with vegetation...
...savage, Siberian culture, with roots as far away as the Ural Mountains. Among the remarkable objects found in Ipiutak ruins are chains and swivels cut laboriously out of walrus ivory. They have no strength and are obviously not for use. Larsen believes that the Ipiutaks, pushing farther & farther into Arctic America, eventually lost touch with their sources of metal. But their religion still demanded certain objects, so their artists copied the metal chains and swivels faithfully in ivory, hoping that the gods would not notice the difference...
...Alaska proved that conventional liquid-cooled engines were impractical for such climates. It put Continental, the biggest maker of air-cooled engines for tanks in World War II, to work. Jack Reese claimed-and Army Ordnance backed him up-that the engine will operate efficiently in desert heat or Arctic cold, and weighs only one-third as much as liquid-cooled jobs of equivalent horsepower. Developed by Continental Engineers Carl F. Bachle and Edward A. Hulbert, the new engine is simple in design and requires only a small stock of spare parts...
Migrating birds are excellent navigators, hitting small oceanic islands like radio-guided airplanes. But some of them seem to cross unnecessary oceans. The Arctic tern, for instance, nests in summer in North America; when winter approaches, it heads for Antarctic regions near South America. But instead of flying south, the most direct route, it heads eastward across the North Atlantic to Europe, then down the African coast and across the South Atlantic. Other birds that migrate long distances take similar detours. All this tends to vex and confuse the ornithologists, who want to know why birds behave that...
Some three weeks ago a well-heeled expedition, sponsored by the National Geographic Society, Cornell University and the Arctic Institute of North America and equipped with airplanes, motion picture cameras and other up-to-date gadgets, made a serious attack on the curlew's domestic privacy. Last week the exciting news was flashed to Dr. Gilbert Grosvenor, president of the National Geographic Society, from Dr. Arthur A. Allen, head of the expedition: "We have found the curlew's nest." It was at 62° north latitude, 164° west longitude, near Mountain Village on the lower Yukon...
