Globally event appears unlikely to have a significant cooling effect on temperatures globally, h >"However, to date, it injected 'only' 0.4 Tg (400,000 tonnes) of sulphur dioxide into the atmosphere, which is not enough to result in significant surface cooling for this individual eruption. "Unless further eruptive activity occurs, we should not detect significant surface cooling. At present, hazards related to ash fallout are really the number one concern." https://news.abs-cbn.com/spotlight/01/19/22/explainer-tonga-volcano-eruptions-effect-on-global-climate https://news.abs-cbn.com/spotlight/01/19/22/explainer-tonga-...
