North will remain North for now, say geo-magnetic boffins

Re: Be prepared!

There are even possible correlations with climate changes. There's a theory that cosmic rays can produce cloud condensation nuclei or CCNs, leading to changes in cloud cover, precipitation and weather. So if our magnetic field declines, that may have more of an impact. The SAA's potentially an interesting place to observe that, but I suspect challenging given that's mostly over ocean.

But there's also the potential for shorter term events like the Carrington Event in 1859, which was a large CME (Coronal Mass Ejection) that damaged power and communications. A repeat would be far more damaging today, and there's a realisation that protecting against CMEs would be a good thing. But an expensive challenge.
