• On January 15, 2022, the Hunga Tonga-Hunga Ha'apai volcano erupted with unprecedented force, sending a plume 35.4 miles into the atmosphere, reaching the mesosphere. This eruption was unique due to its ability to inject 146 teragrams of water vapor into the stratosphere, significantly more than any previous recorded eruption. Unlike typical volcanic eruptions that warm the stratosphere through sulfate aerosols, this event led to a cooling effect of 0.5 to 1 degree Celsius in the upper atmosphere. The eruption's impact on global temperatures was minimal, with no significant effect on the record heat years of 2023 and
• The eruption also caused atmospheric pressure waves that circled the globe and triggered a meteo tsunami in the Mediterranean.
