QotD: The next “Carrington Event”

Filed under: History, Quotations, Science, Space — Tags: , — Nicholas @ 01:00

The last one happened in 1859. The Earth was hit by a cloud of magnetized plasma from a “coronal mass ejection” — something that our Sun often does. Most fly off in other directions; the last that barely missed us was in July, 2012. (You can tell it missed from the fact that the Internet still exists.) The last bullseye on our beloved planet was named after the brilliant English amateur astronomer, Richard Carrington (1826–75), who, in the course of figuring out what happened, demonstrated the existence of “solar flares.”

He was trying to explain why telegraph operators all over the world, on the 1st of September, 1859, were suddenly getting electric shocks; and then, prior to the whole cable system going down, why some had been able to send and receive messages even after disconnecting their power. Too, why auroras had lit up the night sky at temperate latitudes so bright people could read newspapers by it; or why those at higher elevations near the equator could enjoy the aurora borealis and the aurora australis — simultaneously.

Now, the world a sesquicentury ago was not so dependent upon electricity as it is today. And the system of telegraphy was so ridiculously simple, that it was soon repaired. I daresay Morse Code is worth learning in preparation for the next Carrington Event — which, when it comes, we will be able to predict, at best, a few hours in advance. (Other cosmic events might impinge on our lifestyles meanwhile, but I like to consider my apocalypses one at a time.)

Gentle reader may do a mental inventory of the gizmos in his environment that are connected directly or indirectly to the power grid. Then add in anything that contains a computer chip, whether it happened to be “on” or “off” when the Earth’s magnetic field was impacted. For I assume it will all turn “on” of its own, for a brief but memorable interval.

The “beauty” (as they say in Cape Breton) is that we have no back-up system, and moreover, there can be no back-up, except what we can rig from horse, or paddle. For we have made ourselves totally dependent upon sparks.

On the plus side, the environmentalists may exult, because the quick reduction of the world’s population to post-Plague mediaeval levels could prove a lucky break for the other endangered species.

It will, even more happily, improve national security for the survivors in USA. For the same magnetic storm that makes the cities (and towns) of America uninhabitable will also have disabled the military capacities of Russia, China, and Iran. If they want to come at us they will have to do so in sailing ships. Moreover, the depopulation of Mexico will probably reduce the invasion threat from there, whether or not Donald Trump is President.
