There's reports of Aurora's in Puerto Rico. Last time they were seen this far south was 103 years ago.

This is a new excerpt from the news station "Primera Hora"

> "Por Primera Hora. 11 de mayo de 2024 • 7:53am. Las aurora borales que decoraron el cielo anoche se lograron ver en Puerto Rico, fenómeno que no se veía en la Isla desde hace 103 años"

English Translation:

>"For First Hour. May 11, 2024 • 7:53am. The northern lights that decorated the sky last night were seen in Puerto Rico, a phenomenon that had not been seen on the Island for 103 years"

FWIW, this is light years away from the impression that Food Not Bombs people and activism has left on me over a couple decades of occasional, incidental contact.

That's a shame. I'd be curious generally which area they're in and how they're different over there, I'd want to go and chat and see what's up.

My most recent experiences were not recent, to be fair.

But the locations were primarily Boston and San Francisco.

Demonstrably false. Did you even look at the map linked in what you responded to?

While the photos of the auroras which have been circulating are certainly impressive, this has got me thinking about the Carrington Event [1], as well as a possible future event of equal or greater magnitude. I'm not an electronics expert, but I'm guessing that the reason we're so vulnerable to such an event today is because our infrastructure was originally built without such an event in mind, and now the upgrade co…

No one would be willing to spend for an extreme level black swan event that is not proven to have ever happen. That said, the magnetic field is down 15% since the carrington event. Magnetic poles are moving fast (north to siberia, south outside antartica already) to meet around indonesia. When the sun will go micronova there's little chance electrical systems and the like will survive. Anyway the CME is the least of the worries, consider the earth reacts to such an event in unexepected ways...

Interesting, what's the proposed mechanism for CMEs causing fires? I unfortunately can't access the paper text.

Current is _generated_ in static lengths of wire. At any point the voltage exceeds the design, it arcs. Current passing through imperfect conductors are heating elements. Both sparks from shorts and excess heating of conductors are possible ignition points. n.b. I have not look at the paper.

Oh, so you mean it might just be power (or other metal) lines causing fires indirectly?

I'd be very surprised if anything naturally occurring in a forest would be long and/or conductive enough to be a problem even during very strong geomagnetic storms.

We also solved Peak Oil, Acid Rain and saved the whales.

In what way did we solve peak oil - by continuing to burn more every year? Climate scientists are going out of their minds. Is PFAS rain that much better than acid rain? Rainwater is no longer safe to drink anywhere on Earth . As for the whales, that's nice they got a reprive... But we're still extinctifying species at 100-1,000x the background rate. And the people responsible for all of this are not strung up, nor e…

Peak Oil was about the world running out of oil.

Ah, so we 'solved' it by finding so much more oil that life on Earth would be burned to a crisp long before we used it all, then just burning more every year.

All while subsidizing oil companies to an absurd degree, even as they make record profits and avoid liability for environmental disasters.

So glad we 'solved' that. How great for us, and what an interesting example of how we come together to solve global scale crises that was.

Maybe we can solve PFAS rain by coating everything in Teflon so the PFAS don't stick.

I guess that's one upside of living off of city water / sanitation. In my circumstance I wouldn't have a change of living due to well water pump being easily run from solar collected electricity. It would only have to run the pump a few times a day to keep the well bladder tank primed. Same thing for the mound system as the pump only needs to run a few times a day during normal operations. This could just be run once…

I'm in the same boat, and have a lot of power failures. So when I replaced my tank, I made sure I went for a 80gal size / 40 gal badder. I also upped my pressure from 30/50 to 50/80, so that I have more pressure in there regardless. But I've noticed a disturbing trend. A lot of people now have "continuous" pump/tank setups. A little pressure tank the size of a 20lb BBQ propane tank, just to allow for pressure stabili…

I had an irrigation guy try to sell me on the "continuous" pump setups. While you minimize some of the internal infrastructure - I agree with your take. The continuous system puts a ton more strain on the pump. The other piece is lift - even at 70 psi water pressure diminishes quite a bit if you're traveling three floors (basement, 1st, 2nd).

Definitely sad.
