|Could global warming produce a big chill?
By David Arnold, Globe Staff, 10/1/2002
OODS HOLE - In what would be a surprising byproduct of global warming, average temperatures in North America and Europe could drop by 5 to 10 degrees Fahrenheit in the coming decades as melting polar ice and increased water evaporation profoundly alter the ocean currents that keep both regions warm, say researchers at the Woods Hole Oceanographic Institution.
Terrance Joyce, chairman of the Woods Hole Department of Physical Oceanography, said he believes that key parts of the Gulf Stream ocean current system could virtually shut down, perhaps in our lifetime, reducing or cutting off the flow of warmer water from the equator to the North Atlantic. If these key features, called thermohaline pumps, shut down, it would signficantly cool northern latitudes, including New England.
