This is the last in a series of posts inspired by the news that, during its annual meeting in December, the American Geophysical Union will hold a workshop on possible climate effects from the 2022 Hunga Tonga blast, which injected LOTS of water into the normally dry upper stratosphere.
Hopefully, the workshop still will be held and the subject debated objectively by the best minds on the planet even though US policy makers have already ruled out, apparently via some sort of metaphysical revelation (since the opinion is expressed without data support and in The Hill rather than in a scientific journal), any connection between this unprecedented eruption-induced stratospheric loading and climate effects since January 2022.
From what I’ve read, possible effects from such stratospheric hydration theoretically can be expected to continue for a couple years more.
Anyway, here at this blog we’ve looked at the stratosphere as well as at the eruption.
Now it’s time to check out what is known about ordinary volcanic effects on climate. Since it’s only possible to do videos here, presentations get extreme quickly:
- Super simple:

Not bad, but having lived through the CFC ban decades ago, I disagree with her about spray cans.
- A lecture.
There are several online and I’ve chosen this one because it is the most like reading a book.
She actually doesn’t get into atmospheric aerosol until around the thirty-minute mark — and then only as much/little as that animated film did — but I like the whole discussion as an intro, that is, covering typical volcano stuff that we laypeople don’t usually associate with fire mountains.
The 2022 Hunga Tonga eruption was so different from this:
