A flipflop of Earth’s magnetic poles between 42,000 and 41,000 years
ago briefly but dramatically shrank the magnetic field’s strength — and
may have triggered a cascade of environmental crises.

Very solid science, I'd say. And it's good that they are continuing to investigate questions that arise.
If the ozone layer backed off on blocking the sun's rays, they might have had some "Global Warming" in those days, despite the total lack of gas-powered vehicles.
I'd like to be kept up-to-date on this research!

I'll post more about it if I get more. I'm spread a bit thin on this these days (and on everything else.)

I've caught a break Dana; they excused me from jury duty because of Cathy. She fell down on Sunday (mainly because a mouse startled her by running between her feet). I told the people there about that and her health issues and they gave me another year.
