The ferocious winds of tropical cyclones churn up ocean water as they spin over the surface, significantly affecting the transport of heat in the ocean, a new study finds. And as global warming heats up the ocean surface, this process could be intensified, preventing the potential shutdown of the oceanic conveyor belt. The intensification could also have strange effects on storms. Lire la suite

WASHINGTON – The head of NASA drew criticism from scientists when he said he was not sure global warming was a problem. “I have no doubt that global � that a trend of global warming exists,” NASA Administrator Michael Griffin said in a taped interview that aired Thursday on National Public Radio. “I am not sure that it is fair to say that is a problem we must wrestle with.” Lire la suite

I was diving just south of Lancaster Sound, off the northern tip of Baffin Island in the Canadian Arctic. The water was 29 degrés (-2�C), about as cold as seawater gets before it freezes.

De la haute montagne aux feuilles de vastes glaces polaires, le monde perd sa glace plus rapidement que quiconque croyait possible. Même les scientifiques qui avaient suivi depuis Chacaltaya 1991 pensé que ce serait tenir pour quelques années de plus. Il n'est pas surprenant que les glaciers fondent que les émissions des voitures et l'industrie réchauffer le climat. Mais dernièrement, la perte de glace a dépassé le fluage à la hausse des températures mondiales. Lire la suite
