Xinhua: To cool planet, researchers propose spraying particles into marine clouds

"A group of researchers at the University of Washington (UW) is investigating the idea of marine cloud brightening as a strategy to offset global warming. As a short-term measure for a possible future emergency situation, the strategy involves spraying saltwater into clouds above oceans to boost their capacity to reflect sunlight. In a paper published in the journal Earth's Future, two UW researchers, including lead author Rob Wood, a professor of atmospheric sciences, say small-scale tests of marine cloud brightening would also help answer scientific questions about clouds and aerosols' possible role to help cool the planet."
