Curious if this will cause a slight cooling of the earth's air temperature due to increased volcanic particles in the air. I had no idea of the size of this eruption and it looks absolutely enormous based on this article. It didn't mention how many metric tons were ejected into the atmosphere Here is an article saying that after a eruption the air temperature rapidly cools for a while. Lets hope this doesn't wreck crop production. https://www.scientificamerican.com/article/volcanoes-cooled-earth-in-the-past-constrain-warming-from-excess-co2/ https://www.scientificamerican.com/article/volcanoes-cooled-...

Not this time apparently. > Pinatubo erupted for several days, sending about 20 million tons of sulfur dioxide gas into the stratosphere, or upper atmosphere. There, the gas combined with water to create aerosol particles that reflected and scattered some of the sun’s rays, keeping them from hitting the surface. That had the effect of cooling the atmosphere by about 1 degree Fahrenheit (about half a degree Celsius) for several years. (It is also the mechanism of a controversial form of geoengineering: using planes or other means to continuously inject sulfur dioxide into the stratosphere to intentionally cool the planet.) > But the Hunga eruption lasted only about 10 minutes, and satellite sensors in the days that followed measured about 400,000 tons of sulfur dioxide reaching the stratosphere. “The amount of SO2 released is much, much smaller than, say, Mount Pinatubo,” said Michael Manga, an earth sciences professor at the University of California, Berkeley. So unless the Hunga eruption resumes and continues at a similarly strong level, which is considered unlikely, it won’t have a global cooling effect. - https://www.nytimes.com/2022/01/19/climate/scientists-tonga-volcano-eruption-effects.html https://www.nytimes.com/2022/01/19/climate/scientists-tonga-...
