Giant Tonga Volcanic Eruption Could Disrupt Weather for Years to Come

- bamboozled 2y agoIn terms of global mean temperatures, which are a measure of how much climate change we are experiencing, the impact of Hunga Tonga is very small, only about 0.015 degrees Celsius. (This was independently confirmed by another study.) This means that the incredibly high temperatures we have measured for about a year now cannot be attributed to the Hunga Tonga eruption. For those of you planning to read this to find some positive climate news. Don't bother.
- fragmede 2y ago> 0.015 degrees Celsius roughly how many tons of TNT would it take to heat the atmosphere that much?
- cenamus 2y agoProbably actually colder, due to the ash in the atmosphere? Like the cold period caused by Mount Tambora. https://en.wikipedia.org/wiki/Year_Without_a_Summer https://en.wikipedia.org/wiki/Year_Without_a_Summer
- RetroTechie 2y agoSounds like a fun "What If?" question (xkcd). But our planet (and with it, atmosphere) is hardly affected by humanity's activities adding heat directly. Instead it's GHGs that affect the inflow/outflow balance of heat from the sun. The heat from gasoline you burn is quickly dissipated. But the CO2 produced has an effect for many decades to come.
- fragmede 2y agoAlright, I've emailed Randall Munroe.
- pmayrgundter 2y agoThe story above cites a confirmatory study for its ozone hole result and should also cite contradicting studies for its warming result. There was a study out of NASA/JPL that made a correct and timely prediction of major warming a year in advance (i.e. arriving last fall) It gave a forcing estimate of +0.15 Wm−2, *equivalent to half a decade of global human CO2 forcing* arriving mainly at 18-24 months after Jan 2022 (last fall) and lasting for 5+ years
- bamboozled 2y agoWhat does the study predict as being the cause? Undisclosed ?
- pmayrgundter 2y agoWhoops, meant to say Tonga, the same event Here's the study https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL099381 https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/202...

- jmlim00 2y agoWas expecting some good news from this article exactly. Bummer.
- pfdietz 2y agoAs a ballpark estimate, 100,000 launches of SpaceX's Starship would put about the same mass of water into the stratosphere.
- RetroTechie 2y agoNo mention of the NaCl from the seawater? If you boil seawater slow enough, yeah hardly any salt would be carried off with the water vapor. But undersea volcanic eruption? I'd imagine at least some salt would end up where the water vapor does. And at ~3.5% (weight % of ocean surface), that could put a fair amount of NaCl particles in the upper atmosphere.
