# Neanderthals May Have Been Killed Off By Magnetic Pole Flip

## Polar Opposites

Scientists have discovered evidence that Earth’s magnetic poles flipped 42,000 years ago — possibly leading to the Neanderthals’ extinction.

Researchers from Sydney’s University of South Wales (UNSW) and the South Australian Museum released [a paper describing the findings](<https://science.sciencemag.org/content/371/6531/811>) in the journal *Science* detailing how the reversal of the poles caused abrupt solar storms and climate shifts that could have killed off humans' closest ancient relative.

## Extinction Evidence

According to the work, the flip caused Earth’s magnetic field — which protects the planet from harmful radiation and particles from the sun — to almost disappear.

"Unfiltered radiation from space ripped apart air particles in Earth’s atmosphere, separating electrons and emitting light — a process called ionization," Chris Turney, professor at UNSW Science and co-author of the study, [said in a statement](<https://www.cnn.com/2021/02/19/world/magnetic-fields-earth-intl-scli-scn/index.html>). "The ionised air 'fried' the Ozone layer, triggering a ripple of climate change across the globe."

In the paper, the researchers hypothesize that the magnetic flip triggered "pronounced climate change" along with a host of scary-but-beautiful cosmic events such as frequent northern and southern lights, electrical storms, and violent weather.

## Future Flip

There’s some evidence that indicates that our poles are headed towards another reversal event. If that happens, it’ll cause a global catastrophe that makes *The Day After Tomorrow* look like *Snow Day.*

"If a similar event happened today, the consequences would be huge for modern society," says Alan Cooper, co-author of the study, said in a statement. "Incoming cosmic radiation would destroy our electric power grids and satellite networks."

Of course, with a global pandemic, wildfires throughout the northwest, and catastrophic snowfall in Texas, a world-ending magnetic reversal might just be on brand these days.
