Interestingly this happens every 11 years and also their is a longer cycle called the Hale cycle which is double the length at 22 years. It flips from a mostly dipole where the poles match the orientation of earth to a reverse and much more irregular magenetic orientation. I didn't see anything about how this really affects Earth directly other than what I knew previously about sun spots make Coronal Mass Ejections s…

Mostly affects cloud formation [1] 1. https://home.web.cern.ch/news/news/physics/cloud-discovers-n...

You might want to find a better link.

That specific article, while interesting, doesn't mention the sun's magnetic field once.

Nor the sun, nor magnetic fields.

Its so perplexing to me how the laws of physics replicates simple properties into massive scales.

so then i wonder why do people struggle with the impact of polar shifts on climate?

What makes you think that people do struggle?

Are you hinting at the sun's poles or the earth's? Further do you mean the rotational pole, or the magnetic poles?

FWiW, NASA has written on all of these, for example:

Why Variations in Earth’s Magnetic Field Aren’t Causing Today’s Climate Change

So... What's the range and how do we modulate it?

The range would be awesome, but the city took pretty significant offense to my plan to setup a 11 lightyear dipole antenna on my property. It's a hard life being an amateur radio operator these days...

Hopefully you hadn't bought the metal for it yet, 208 cubic kilometres isn't easy to store.

The food pyramid is misunderstood 'those scientists' were from Sweden responding to protests over the increasing costs of food due to famine. When looked at from the lens of maximizing calories per dollar, it makes a lot more sense.

it could have been divine revelation. what matters is that it is used to this day for policy.

Which is not what you said originally, when you disparaged those who created the food pyramid,

Regardless of the cause of climate change, on any time scale (even if it is a 100% natural cycle and human effects are zilch in the grand scheme), pollution is icky and hey, I'm walking^W living over here .

With respect, 2/3 of the carbon dioxide out there is purely natural such that “icky” isn’t an appropriate foundation for the relevant public policy

With respect, they said pollution is the icky part. I’m not aware of any major industries that are responsible for an appreciable amount of CO2 emissions and no other pollutants/icky stuff, but I’d love to be proven wrong about that.

Which made me think. I would expect other stars to do this. Would magnetic polarity be detectable at interstellar distances? could novel astronomy* be done on stars this way?

* Does the magnetic flip period tell us anything about the star that would otherwise be hard to figure out.

Makes sense. In a similar vein, once fast food places started stating calories per item... It actually helped me maximize calories per dollar and eat more calories, which seems opposite of the original goal of helping people limit their calories. Who is going to fast food to keep calories low?

> . Who is going to fast food to keep calories low?

I'd guess that there are more people use that information to select lower calorie food than people who make their menu selections based on the maximum number of calories per dollar, although I'd bet both those groups are a tiny fraction compared to the number of people who just order whatever they're in the mood for/tastes best to them and knowing how many calories are in that meal doesn't influence their behavior/choices at that moment but may still inform their choices later on

and that one word a century baud rate is a bit of a downer.

So going off of the previous HN thread, I thought we were due for a Carrington event a month ago ( https://news.ycombinator.com/item?id=40321821 ). Will this next bout of astronomical magnetic phenomena pose a threat to technological civilization as we know it?

Perhaps. The Carrington event was 2-4 times as strong as the one last month, but on the other hand it also looks like most of the electrical systems are a lot more resilient than they used to be.

I am curious about how would the general public be made aware of another Carrington-class storm. NOAA rated May 2024 storm as G5, which is the highest rating for a geomagnetic storm regarding its effect on the public.

Just need Bruckheimer + Bay and/or Emmerich to make a couple of disaster movies about the concept to incept it into the public's mind. Hopefully that will then provide NOAA the popular support to do what they need to do.
