Greenhouse gases could affect ocean circulation

Authors


Abstract

The buildup of greenhouse gases could precipitate an abrupt collapse of the oceans' prevailing circulation system and send temperatures in Europe plummeting about 10° Celsius or more in a span of 10 years, says Wallace Broecker, professor of Earth and environmental sciences at Columbia University's Lamont-Doherty Earth Observatory, and author of new research that appears in the November 28 issue of Science magazine.
