WASHINGTON - Florida's humidity is hard to bear.

Scientists say it might get worse, thanks to global warming.

According to a study published today in the journal Nature, the amount of moisture in the air near the surface - the stuff that makes it humid - increased 2.2 percent in a little less than three decades. The researchers say the only explanation is man-made global warming.

Climate scientists have seen the man-made fingerprint of global warming on 10 aspects of Earth's environment: surface temperatures, humidity, water vapor over the oceans, barometric pressure, total precipitation, wildfires, change in species of plants in animals, water runoff, temperatures in the upper atmosphere, and heat content in the world's oceans.

Increases in humidity can be dangerous to people because it makes the body less efficient at cooling itself.
