I'd like to see the papers without the summary.
Papers will provide conditions, the who, what, when, where, perhaps a 'why', and potential sources of error, and recommendations for further future research.
A hypothesis remains a hypothesis until a consensus is agreed upon by a number of other experts in the same field.

I don't recall any lifeform-affecting phenomena on Earth ever being associated with a magnetic excursion. Certainly not any 'disaster.'
It would be like saying that kitchen magnets could destroy the world.

A look at NASA / Jet Propulsion Laboratory revealed zero research being conducted for Earth 'disasters' related to geomagnetic excursions. That would be a clue.
