Global warming pioneer dies at 87


The Associated Press NEW YORK (AP) – A scientist who raised early alarms about the climate change and popularized the term "global warming" has died. Wallace Smith Broecker was 87.

The longtime Columbia University professor and researcher died Monday at a New York City hospital, according to a spokesman for the university's Lamont-Doherty Earth Observatory.

Kevin Krajick said Broecker had been in ailing in recent months.

Broecker brought the term "global warming" into common use with a 1975 article that correctly predicted rising carbon dioxide levels in the atmosphere would lead to pronounced warming.

He later became the first person to recognize what he called the Ocean Conveyor Belt, a global network of currents affecting everything from air temperature to rain patterns.

"Wally was unique, brilliant and combative," said Princeton University Prof. Michael Oppenheimer.

"He was not fooled by the cooling of the 1970s. He saw clearly the unprecedented warming now playing out and made his views clear, even when some were willing to listen. "

In the Ocean Conveyor Belt, cold, salty water in the North Atlantic sinks, working like a plunger to drive an ocean current from North America to Europe.

Warm surface waters borne by this current help keep the Europe's climate mild.Speech
