Noted: UW-Madison physics professor Jan Egedal tells me that, within the community of solar physicists, “it is well known that a Carrington-level disturbance today would be devastating.” If wide swaths of the highly interconnected North American electrical grid were damaged, backup generators would conk out long before the multitude of necessary grid repairs could be made. Lack of electricity itself might hamper the manufacture and transport of the required replacement equipment.
