The article reports that in 2005 oceanographers reported a sudden and shocking slowdown in the currents of the North Atlantic, a critical part of the vast system of ocean circulation that influences temperatures and weather around the world. A shutdown could cause famine in south Asia, kill off the Amazon rainforest and plunge western Europe into a mini ice age. The conclusions reported last year have been dismissed by many climate scientists, who say their models show the current will keep going for at least another hundred years or so. The glaciers that drain the ice cap are accelerating, and in the past decade the amount of ice they spit into the ocean has doubled. If currents hold fairly steady until the late 21st century, the cooling effect of a shutdown would help to mitigate warming.
