Solar Storms Are Back, Threatening Life As We Know It On Earth by Brian K. Sullivan

Solar storms have their roots in an 11-year cycle that shifts the polarity of the sun’s magnetic field. The magnetic forces at work on the sun get tangled during the process, and can punch out through the surface, sending the sun’s plasma into outer space and potentially triggering storms on Earth. The most powerful geomagnetic storm ever recorded resulted in the 1859 Carrington Event, when telegraph lines electrified, zapping operators and setting offices ablaze in North America and Europe. If a storm of that magnitude were to hit today, it would likely cut power to millions if not billions of people. “When I first started on this road and was briefed on space weather I raised an eyebrow,” said Prouse. “It is much more mainstream and some of the mystification is gone. You can now raise it as a risk and not get laughed at.”
