Warming is accelerating global water cycle
Fresh water evaporates from the oceans, rains out over land and then runs back into the seas. A new study finds evidence that global warming has been speeding up this hydrological cycle recently, a change that could lead to more violent storms. It could also alter where precipitation falls — drying temperate areas, those places where most people now live.
