Solar Storms Can Devastate Entire Civilizations

Solar Storms Can Devastate Entire Civilizations

Solar flare

Climate has inarguably become a hot topic of discussion in developed economies over the last decade, and it is getting hotter by the day as study after study warn we are close to doomed if we don’t change our ways urgently. Yet climate on Earth is not the only problem that humankind faces. There is another climate we need to pay attention to, and there is nothing we can do to change that.

Solar storms, whose more scientific name is coronal mass ejections, were until recently believed to be a rare occurrence—only happening once every couple of centuries or so. However, there is reason to believe they may be a lot more frequent than that. In a world increasingly dependent on electricity, this is, to put it mildly, a problem.

In 1859 the Sun spewed concentrated plasma that broke through its magnetic fields in the direction of the Earth. Commonly referred to as the Carrington Event, that coronal mass ejection hit the Earth’s magnetic field, which warped it and caused telegraphs around the world to fail. For a long time, the scientific consensus was that solar storms of this magnitude were a rarity.

That was in the 19th century where telegraphs were cutting-edge tech. Now, we have power grids, airplanes, satellites, and computers, and all of them are potentially susceptible to the effects of another solar storm. We also know that solar storms of the magnitude of the Carrington Event or even worse occur more frequently.

“The Carrington Event was considered to be the worst-case scenario for space weather events against the modern civilization… but if it comes several times a century, we have to reconsider how to prepare against and mitigate that kind of space weather hazard,” the lead research in a study that reached that conclusion, Hisashi Hayakawa, said after the release of the study earlier this month.
