the earth's magnetic poles have already flipped at least 10 times in the past few million years. I recall reading that there could be a long period of increased solar radiation affecting life and causing a lot more cancer during the period that the actual reversal takes place but it's all theoretical.
- giantg2 4y agoI doubt there would be that much extra cancer. The estimates I saw were merely a 25% reduction in field strength. The predictions I saw were more concerned about technology failures. A slight increase in solar radiation seems like small potatoes compared to all the other potential carcinogens we live with, but it does seem like it could be significant for our electronics.
