Sadly, I think it's probably realistic to assume that the vast majority of that time will be eaten by bureaucratic indecision and that global power and telecommunication infrastructure will suffer considerably.
Perhaps at some future "earth day" it would be wise to test the shut-down of significant portions of our power and telecommunications systems.
- ksaj 5y agoWhen the electrical grid went out for a part of Canada and the US for a few August days a while back, we got a taste of what could happen. It would take a lot longer to get up and running again in the case of an overly-well directed EMP from the Sun. As far as I know, we don't have technology for dealing with it if it does happen. But we have had practice and incentive to improve the outcomes.
