Re: Carrington Event
#2Anyone know of an estimate of the cost of hardening the US grid so that there wouldn't be an enormous death count, and likely societal collapse? The danger seems to be very real. See the paper discussed here:

Probably the cost of a gadget that detects the extra d.c. and injects and equal and opposite current to null it out, for every major power transformer in the land.

I think the number I saw was Carrington was something like 8.9 while this is 8.4, and that's a huge difference on the scale used here.

Or just breaks the circuit, like a fuse. Better for the grid to fail in a way that can be recovered from quickly than for it to fail and burn itself to the point that recovery takes years.

In layman-friendly terms, the scale goes from G1 to G5.
The one in 1859 was classified as G5 (extreme), and the one the other day was the very first time G4 warning has been issued. Not as in "it'll definitely be G4", but more along the lines of "it'll be G3, possibly increasing to G4 for a brief period of time".
There's also a more "scientific" scale called the K-index (https://en.wikipedia.org/wiki/K-index), but I don't understand it well enough to be able to explain it.
