PARIS – 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 today 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 and Europe, and also help the temperatures in the tropical Pacific to remain stable, they suggest.
This time last year we were being served up the standard line on AGW , namely that the planet’s climate was on an inexorable warming trend and that if we failed to take substantial measures to combat the emissions of Co2 then we were all sure to fry. More recently we have begun to see more and more reports suggesting. that our future may be cooler rather than warmer. Like the one that I quote above. while this piece suggest that we may see a period of cooling before a return to the much mooted AGW warming trend I find it rather hard to believe that the soothsayers have any idea at all. When it is impossible to predict with any accuracy what the weather will be like tomorrow I see no reason to accept claims that cooling temperatures mean that “Global warming” is happening as claimed by the likes of Gore and Flannery et al.
