Here are some links about the potential modern effect of a Carrington scale event.

These IT pros include a video which I did not watch because my IT savvy partner is too busy on HIS PC, and if I look at a Video it interferes with his activities on line. Grrrr

This link mentions a relatively recent much milder CME event that took place in March. It hit parts of Canada, and I try to imagine the whole north of the central US and Europe being hit with something stronger but still not Carrington level. Also cost estimates in $trillions.

After a noticeable CME event 4 years earlier, this 2011 NG article postulates effects for our technology 10 years ago.

In a completely different vein, this link causes me to ask has civilization caused our brains to shrink. I believe it has been reported our brains are smaller than Cro Magnon’s. Most of us are now domesticated. Every day I see people I know would be dead in a week. Is this why girls are attracted to the wild boys? Remember the 2000 deaths in New Orleans from Katrina, including in the so called big shelter.
So, folks, I have a question. What would happen if Putin decided to start his attack on Ukraine just when a major CME hit?
Kabuki theater. He recognized his illegal puppet states, then sent troops in apparently after Biden announced the sanctions.
