New Study Reveals 2022 Hunga Tonga Volcano Eruption Cooled Earth’s Climate
Recent research from a team including Dr. Andrew Dessler, an atmospheric scientist at Texas A&M University, is challenging the widely held belief that the 2022 Hunga Tonga volcano eruption contributed to Earth's recent extreme warmth. Contrary to initial assumptions, their findings indicate that the eruption actually had a cooling effect on the global climate.
The Hunga Tonga eruption, occurring over two days in mid-January 2022, was a significant event, releasing vast amounts of volcanic aerosols and water vapor into the atmosphere. Unlike past volcanic eruptions, such as Tambora in 1815 and Mt. Pinatubo in 1991, which led to global cooling by blocking sunlight with aerosols, Hunga Tonga's underwater eruption added an unprecedented amount of water vapor to the stratosphere, increas...
