The Guardian article continues: “Previous work found little evidence that the event had a profound impact on the planet, possibly because the focus had not been on the period during which the poles were actually shifting. Now scientists say the flip, together with a period of low solar activity, could have been behind a vast array of climatic and environmental phenomena with dramatic ramifications.
“It probably would have seemed like the end of days,” said Turney.
Every 12,000 years –or there abouts– our planet suffers a magnetic excursion during which its north and south magnetic poles “wander” and eventually “flip” — this process results in a waning of Earth’s magnetosphere which in turn fuels serious climatic events and mid-level extinction events on the ground.
The devastation of these events is truly “cataclysmic,” because these events are much more than climatic, they also result in a bombardment of cosmic energy on the lower atmosphere as our shield against the Sun fails.
We’ve seen accelerated magnetic field loss in recent years (driven by our wandering poles–visualized above) — and this a key indication that the excursion is winding up, that the poles are readying to flip.
In the mid-1800s, after millennia of stability, the field began waning and has been doing so ever-since — accelerated losses were officially reported as 10 percent in the year 2000, and then, just a decade later, as 15 percent in 2010. 2015 and 2017 accelerations were only announced to the world in 2020 and 2021, and they detected significant shifts in the South Atlantic Anomaly (SAA).
