Scientists have discovered evidence that a reversal of Earth’s magnetic poles might have caused the extinction of the Neanderthals.

And it might happen again soon.
Polar Opposites
Scientists have discovered evidence that Earths magnetic poles flipped 42,000 years ago possibly leading to the Neanderthals extinction. 
Researchers from Sydneys University of South Wales (UNSW) and the South Australian Museum released a paper describing the findings in the journal Sciencedetailing 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 Earths 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 Earths 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. 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
Theres some evidence that indicates that our poles are headed towards another reversal event. If that happens, itll 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.
