There's trouble in the air. Specifically, in the air off the west coast of the Americas, where the sea surface has been heated to abnormal extremes by an ominous, intermittent flood of hot water called El Nino.
The last time conditions looked like this was when the strongest, most destructive El Nino on record struck in 1982-83. By the time that event subsided, some 2,000 people had died in flooding, mudslides, droughts, fires and sundry related calamities, hundreds of thousands were forced out of their homes, and economic losses topped $8 billion worldwide - $1.5 billion in the United States.
This year's version promises to approach or even equal 1982-83, which climate researcher James J. O'Brien of Florida State University's Center for Ocean-Atmospheric Prediction Studies (COAPS) calls "the mother of all Los Ninos." Already, El Nino has begun to have dramatic effects in some parts of the world and the U.N.-sponsored World Climate Research Programme warns it "could be the climatic event of the century."
