Global warming? Next decade could be cooler, says study

PARIS (AFP) — Global warming could take a break in the next decade thanks to a natural shift in ocean circulations, although Earth's temperature will rise as previously expected over the longer term, according to a study published on Thursday in the British journal Nature.

Climate scientists in Germany base the prediction on what they believe is an impending change in the Gulf Stream -- the conveyor belt that transports warm surface water from the tropical Atlantic to the northern Atlantic and returns cold water southwards at depth.

The Gulf Stream will temporarily weaken over the next decade, in line with what has happened regularly in the past, the researchers say.

This will lead to slightly cooler temperatures in the North Atlantic and in North America...
