Any idea if this will have a measurably effect on climate change?
I heard from an Anton Petrov video it would reduce the planets average temperature by half a degree for some time, but I don't know where he got that info from.

My colleague's backyard weather station picked up the pressure wave in Christchurch several times as it repeatedly circled the globe. Sea levels in the upper south were a little 'odd', trending higher and more variably than usual, even if not by that much, for a week.
Here in California in the Sierra Nevada, a pressure variation was noticeable around 4am pacific.
30.16 inHg just before, 30.19 spike followed by an immediate drop to 30.14, then basically normalized again.

no, there’s multiple areas with bays, there’s only one Bay Area.
I suspected you were just assuming that, so I googled it, and found quite a few.

I'll celebrate for a whole week whenever the US converts to the metric system. I hope I'll still be young enough to handle it.
Since it's a big "moat" for parts manufacturing (mainly for defense industry)... I predict the USA will give up imperial units when it's empire finally collapses. Perhaps in the next few decades as China builds its own economic sphere.

My back yard weather station picked up the shockwave here in the bay area: https://twitter.com/DavidCWG/status/1482451910154014720 I had no idea that was even possible. Crazy stuff.

You'd be more on point if OP had referred to San Francisco as "The City" as many in the City do; since that's something that's also used in other cities like NYC.
NB: current resident of the Greater Bay Area in China and former resident of the lesser Bay Area in California.
I posted a visualization of the shock wave as a submission, but I"ll repost it here. This is a satellite measurement of integrated atmospheric water vapor (IIUC), so changes in the density of air change the integrated measurement, such that you can see the shock wave travel around half the globe. https://cimss.ssec.wisc.edu/satellite-blog/images/2022/01/22...

139MB is utter insanity for an animated GIF. Crushing it with gifsicle can get it down to 125MB but clearly GIF is the wrong choice of format here. Here's a HEVC compressed video version which is only 25M and suffers only extremely mild softness: http://david.gloveraoki.net/f/32M.mp4 It would probably be even better if I could work with the source video and not the gif version.
In other news IT still takes days to get back to me about getting my BYO device onboarded...
I'm not saying it's a paradox just noticing the juxtaposition
Heard it go bang, 2600km away, echoing through the hills around our place at the top of the South Island of New Zealand. That's pretty staggering to think about it. Then to see other peoples Home Assistants around the world pick up the change in pressure on opposite sides of the planet. Mental, just mental...

I wonder if the eruption could be heard on the exact opposite side of the globe, where the waves converged? This would have been somewhere around 20.570000, 4.620000, in Guezzam, Algeria, according to: https://www.antipodesmap.com
I was wondering the same thing. One factor might be the variation in propagation speed, which is visible for example due to winds near low pressure systems.
Unless you already factored that in...

Um, it's unamerican to use "imperial" units. When you have a revolution, you have to get rid of all things imperial! Therefore US pints are 16oz, not 20oz, and so on for most fluid measures (fluid ounces are based on dry ounces, which are avoirdupois, not imperial).
We kept linear measurements the same (feet, yard, miles). So it's a bit of a stretch to say we're not imperial. I'd say it's "US imperial".
