Oceans cover almost three-quarters of the globe, yet little is known about how gases and aerosols made by ocean microbes affect weather and climate, or how human-produced pollution could influence this process. Now, scientists report they’ve used an “ocean-in-a-lab” to show that air pollution can change the makeup of gases and aerosols that sea spray releases into the atmosphere and, in turn, potentially alter weather patterns.
The researchers will present their results today at the American Chemical Society (ACS) Fall 2020 Virtual Meeting & Expo. ACS is holding the meeting through Thursday. It features more than 6,000 presentations on a wide range of science topics.
“It’s surprising that we don’t know more about the central role of ocean microbes in controlling climate,” says Kimberly Prather, Ph.D., the project’s principal investigator. “They have the potential to influence atmospheric composition, cloud formation and weather. Humans can alter these natural processes in two ways: by changing the microbial community structure in the ocean, and by producing air pollutants that react with compounds that the microorganisms produce.”
