Scientists stunned as volcano cloud destroys methane in the atmosphere

In January 2022, the underwater volcano Hunga Tonga-Hunga Ha'apai in the South Pacific produced one of the most powerful eruptions in modern history. But scientists have now discovered that the eruption also triggered an unexpected atmospheric reaction that partially removed methane, a potent greenhouse gas, from the air. Researchers say the finding could eventually help scientists develop new strategies to slow global warming.
