Corals are not the only recorders of climate history. Jay Noller, for example, a geomorphologist from Vanderbilt University, has been studying ancient sediments from Peru's northern desert, which is among the dryest spots on earth--except during El Nino years. Then and only then, torrential rains from a succession of storms compact surface dust into a layer of fine, red soil. From the age of the soils he has examined so far, Noller concludes that the El Nino cycle has been operating for at least 2 million years, and probably much longer...
...America in the past. Before 1920, they found, El Nino appears to have affected a much larger region of the U.S. than it does today, channeling winter rain and snow all the way up into the Great Lakes and Great Plains. Afterward, however, its sphere of influence retreated to northern Mexico and the American Southwest. Why the shift? It may be, Cole suggests, that El Nino is overlaid on a different climate cycle that is even more important...
...Woods Hole Oceanographic Institution thinks it too is heavily influenced by the sea--in this case by an ocean gyre, a surface current that follows a sweeping circular route. This gyre, he believes, affects the atmosphere by shuttling parcels of warm and cold water between the tropics and northern latitudes...
