Swarm reveals growing weak spot in Earth's magnetic field

5 hours ago (phys.org)

Since the core is spinning as it always has, then dont think we humans caused this one? :)

Our energy needs are always insatiable so thats why I am not a big fan of geothermal, better not mess with the balance down there

  • Or geothermal uptake is nothing compared to regular volcanic activity. Earth's poles swap positions: https://en.wikipedia.org/wiki/Geomagnetic_reversal

    > Reversal occurrences appear to be statistically random. There have been at least 183 reversals over the last 83 million years

    Whether this is part of one is anyone's guess.

    • There was a time when we could say "our greenhouse gas emissions are nothing compared to regular biological processes," and yet here we are.

One thing not mentioned in the article I expected: Does this invite more/less harmful UV radiation? Does it change overall temperature projections?

  • It means more UV radiation. The Hubble telescope for example doesn't run its UV sensors while passing through the anomaly to keep them from getting damaged.

I wish these articles would go all the way showing a decent visualization of the increase.

I remember something like a KML overlay that would display magnetic data on Google Earth, but it was kind of obsolete and didn't had any historical data that could be used to observe change.
