- Earth's magnetic poles are constantly on the move, but they haven't drifted far enough to actually flip in the modern age.
- Researchers know that Earth's poles have flipped in the past, but opinion has been split over what effects such an event might have on the planet and its inhabitants.
- Now, new research suggests that a magnetic pole flip roughly 42,000 years ago brought with it some dramatic changes, and may have changed the course of human history.
Disaster movies have shown us what Hollywood thinks might happen if Earth's poles were to suddenly flip, but the reality of the situation would likely be much different. We don't know for sure how daily life would be affected if our planet's magnetic poles suddenly went wonky, but scientists are constantly looking for evidence of past polar movements in order to get a better idea of what we should expect.
A new study published in Science offers us some useful information thanks to one extremely old tree. The tree, which was still growing when the most recent magnetic pole flip occurred some 42,000 years ago hints at dramatic and possibly catastrophic changes that took place in the atmosphere and on the surface of our planet.
