This is very concerning. The carrington event was not mentioned in this article, but I'm not sure why. It was in 1859, before the mentioned records were kept, but still, a mention would be expected due to the havoc it wreaked on the early telegraph systems.
Definitely hope someone is thinking about making our systems resistant to this.
Over the last few decades, I have noticed more power lines which have a ground line strung above them. These ground wires will provide some protection from a solar storm, so they're at least doing something.
Yes, I'm the kind of person who habitually looks at power lines...
I read another article a few years ago which said that if we had a huge solar storm that knocked out a large percentage of transformers at distribution stations it would take decades to remanufacture them all at today's production capacity.
