Could a Leaking Ocean Current Keep Europe Toasty?

Climate scientists have long theorized that global warming, by increasing precipitation and melting Arctic ice, could eventually destabilize the Gulf Stream, the ocean conveyor belt that carries tropical waters into the North Atlantic and warms Western Europe. The paradoxical result would be a cooling trend for the region, even as the rest of the globe continued to heat up. Now, a new study suggests that the circulation of warm water in the Atlantic may be tougher to disrupt than previously thought. The research, by a team of marine scientists from Europe and the United States, found that “leakage” from a little-studied Indian Ocean current that runs along the east coast of Africa may intensify even as the Gulf Stream weakens, helping keep the northward flow of tropical waters in balance. And the leakage from the current, known as the Algulhas Current, may already be accel...
