What Are Solar Storms and Can They Destroy Civilization?

TL;DR

Solar storms, caused by the Sun's magnetic field interacting with plasma, can disrupt electronics and threaten power grids. While everyday solar flares are harmless due to Earth's atmosphere, severe coronal mass ejections can induce damaging currents in electrical systems. Experts estimate a 12% chance of a devastating storm in the next decade, making preparedness crucial to mitigate potential catastrophic consequences.
