[...] At the heart of the matter, geologists believe, is a disturbance in the outer core of the Earth’s interior (2900km below the surface). This superheated pool of molten metal is what generates the magnetic field.
“If we look at our best numerical simulations of a magnetic field reversal, this is the type of pattern we see right before a reversal,” says Professor Tarduno. “We don’t know if the current (anomaly) will lead to a full reversal.”
If the anomaly continues to grow, a larger patch of near-orbit and our planet will become increasingly exposed to harmful rays and solar storms.
The last time Earth’s magnetic poles reversed was some 780,000 years ago.

Magentic fields at both poles are acting up recently: https://soylentnews.org/article.pl?sid=19/01/13/1128250 [soylentnews.org]

It's a Chinese conspiracy to undermine our economy because the people all around the South Atlantic oppose The Wall and there are colluding ! No further studying shall be allowed, and anyway NASA is furloughed.
Done. The rest of the comments can be about core/mantle physics.

Pole shift on the way. Get ready for lots of clouds reflecting sunlight, leading to a mini-ice age.
