Earth is getting more humid too

With global warming, the world isn't just getting hotter. It's getting stickier. And people are to blame, researchers reported in the journal Nature.

The amount of moisture in the air near Earth's surface rose 2.2% in less than three decades, according to a computer model developed by researchers from the University of East Anglia in England.

Humidity increased over most of the globe, including the Eastern United States, they said. A few regions, including the Western U.S., South Africa and parts of Australia were drier, however.
