Listening to El Niño
Posted October 15, 2009
El Niño is a warming of the eastern equatorial Pacific Ocean that has far-ranging impact on global weather. The strongest El Niños of the past century occurred in 1982-1983 and 1997-1998, when sea-surface temperatures in the eastern Pacific rose more than three degrees Celsius above normal. In a November 29, 2005, lecture sponsored by the Academy's Atmospheric Sciences and Geology Section, Mark Cane of Columbia University's Lamont-Doherty Earth Observatory discussed what El Niño is, how it affects people, and what we know about how the cycle has behaved in the past. He discussed the history of ideas about El Niño, evidence of El Niño's effects over geological history, and how orbital changes of the Earth affected the phenomenon, among other topics.
