"Air pollution in China has cut the amount of light rainfall by 23 percent over the past 50 years, a new study finds.
The cause: Particles in air pollution cause smaller drops of water to form, and smaller drops have a harder time making rain clouds
The result: Bad air could hamper the country's ability to grow food.
It is the first such study to link pollution to altered climate that can directly affect agriculture.
"People have long wondered if there was a connection, but this is the first time we've observed it from long-term data," said study leader Yun Qian at the U.S. Department of Energy's Pacific Northwest National Laboratory. "Besides the health effects, acid rain and other problems that pollution creates, this work suggests that reducing air pollution might help ease the drought in north China."
The study is detailed in the Aug. 15 in the Journal of Geophysical Research-Atmospheres."
