Some clouds cool the earth. But how are these clouds formed? How does the chemistry of the ocean affect their formation? Is this process affected by climate change? Can humans affect cloud formation to increase the cooling effect of clouds, having positive implications for the health of the planet?

Microbiologist William Whitman and marine scientist Mary Ann Moran of the University of Georgia think these are timely questions. They are coauthors of a paper that will appear in the May 12 issue of the scientific journal Nature. The research covered in this news release was funded primarily by the National Science Foundation's Division of Molecular and Cellular Biosciences, along with the Division of Ocean Sciences.

Whitman and Moran's team of researchers discovered key bacterial genes that influence sulfur gas flux from seawater, with important implications for understanding the role of ocean bacteria in cloud formation. "We are now better able to evaluate the impacts of climate change on the process and the implications for cloud manipulation, which has been proposed as a means to mitigate global warming," said Whitman.

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2022 budget of $8.8 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
