  1. Why Raindrops Keep Falling . . . Or Do Not

    Research published in the Sept. 5 issue of Science puts two of the biggest problems in climate modeling--the respective roles of clouds and aerosols--in a new perspective. Of the greenhouse gases in the atmosphere, the one that has the biggest overall effects is a natural one, water vapor. Yet the impacts of clouds on temperature are incredibly complicated and still quite poorly understood: depending on their height, density, and other factors, they can either trap radiation or reflect it back into space. Aerosols--tiny particles or drops of liquid, suspended in a gas--also have big effects on climate, and those …
