When it rains: Rising carbon emissions (finally) making world wetter, study says

Keep the rain boots and slickers handy, suggests new research that indicates the world will get wetter as cities rein in air pollution from power plants, factories and cars.

Climate scientists thought global precipitation would rise in step with rising greenhouse gases that are warming the atmosphere, allowing it to hold more water. But that has not occurred, according to Peter Stott, a climate scientist with the Met Office Hadley Center in the United Kingdom.
