...greenhouse heating does not spawn more hurricanes, it may make the ones that do occur more powerful. In an extensive study published this summer in the journal Nature, Emanuel surveyed roughly 4,500 storms brewed in the North Atlantic and western north Pacific since the middle of the 20th century. He found that the average power of the storms increased 50% in those 50 years. It's a change that, he has little doubt, is linked to global warming. A slightly weaker Katrina may have made all the difference to New Orleans, where the levees were made for withstanding...
...History 1638, “US Social History, from 1920 to the Present;” History 1657, “Native America: The East;” History 1658, “Native America: The West;” History 1851, “20th-Century Japan;” History 1840b, “The Economic History of the Middle East Since 1945;” and History 1907, “West Africa from 1800 to the Present,” according to the agenda. Only two departmental courses previously served as alternates for Historical Studies...
...during the Upper Paleolithic age, when everyone was a hunter-gatherer, and Homo sapiens coexisted with Neanderthal man. They are evidence of the quantum leap in neural connections that gave birth to the uniquely human attribute of consciousness. Lascaux is the most fundamental example anywhere of what the iconoclastic 20th century writer and anthropologist Georges Bataille called "the basic desire of all men, of whatever period or region, to be amazed." Like few other creations of the human hand, it is a patrimony not of any one country or culture, but of humankind as a whole. Yet Lascaux's robust...
...concentrated in southern France and northeastern Spain. Some cultural impulse drove the early Homo sapiens of that region not only to venture deep into caves but also to paint and engrave them. Though some of the caves have been known for centuries, most were discovered - or rediscovered - in the 20th century. Lascaux is the most famous: its grandeur makes it exemplary. But so do its travails, as José A. Lasheras, the director of the museum and cave of Altamira in Spain, acknowledges. "Altamira had the great luck that Lascaux had problems before we did," he says. Like Lascaux...
When it first got under way, early in the 20th century, Modernism was an idealistic undertaking. Clean lines and glass-curtain walls were supposed to bring on a more just, more rational world. After World War II, the style drifted from its utopian foundations and was adopted wholesale for corporate headquarters everywhere. But Foster has kept his connection to Modernism's idealistic strain. His designs are environmentally conscious. His new library at Berlin's Free University is the last word in energy efficiency. And the diagrids of the Hearst Tower use 20% less steel than a conventional frame does...
