What the hell am I going to do with all these south pointing compasses I bought?

Sell them to Trumpers as Mexico Detectors.

Isn't this the part of the movie where the disaster happens exactly as the main scientist guy's political boss tells us not to worry about it?

The study is published in PNAS.

The study must've contained a lot of hard facts to come to these conclusions then.

The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal.

Cool, I hadn't heard anyone connect that to pole reversal, but ok.

Now do the accelerating movement of the North Pole.

FTFA: "However, the magnetic field is not stable, and at irregular intervals at an average of every 200,000 years polarity reversals happen."

So, they haven't got any evidence that it will reverse soon. However, they also don't have any evidence that it won't. Fun fact: it's been about 800,000 years since the last reversal.
