Technology for oxidizing atmospheric methane won't help the climate, researchers say

As the atmosphere continues to fill with greenhouse gases from human activities, many proposals have surfaced to "geoengineer" climate-saving solutions, that is, alter the atmosphere at a global scale to either reduce the concentrations of carbon or mute its warming effect.

"Our work showed that the efficiency of the proposed technology was quite low, meaning widespread adoption of the technology would be required to make any meaningful impact on atmospheric CH4," said Mayhew, a postdoctoral researcher with the U's Wilkes Center for Climate Science & Policy. "Then, our results indicate that if this technology is adopted at scale, then we start to see some negative air-quality side effects, particularly for wintertime particulate matter air pollution."
