Hmnnnn ... sceptical take on this story in Ars Technica: https://arstechnica.com/science/2021/02/study-blames-earths-magnetic-field-flip-for-climate-change-extinctions/ https://arstechnica.com/science/2021/02/study-blames-earths-... > But for most of the rest of the paper, the researchers search for anything that happened at roughly 42,000 years ago and try to tie it to the mix of altered environmental conditions they think were triggered by the Adams event. ... > Other potential connections are extremely tenuous. Modern humans, despite having been in Central Asia for tens of thousands of years, seemed to show up in Europe around the time of the Adams event, and Neanderthals went extinct shortly thereafter. While it's reasonable to suspect that those latter two events are linked, it's not clear why either would be associated with the magnetic field flip and any impact it had on climate.
