Columbia University professor who popularized ‘global warming’ dies at 87
STEPANAKERT, FEBRUARY 19, ARTSAKHPRESS: The longtime Columbia University professor and researcher died Monday at a New York City hospital, The Associated Press reports, citing a spokesman for the university’s Lamont-Doherty Earth Observatory. Kevin Krajick said Broecker had been ailing in recent months.
Broecker brought “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 professor Michael Oppenheimer. “He wasn’t fooled by the cooling of the 1970s. He saw clearly the unprecedented warming now playing out and made his views clear, even when few were willing to listen.
