Climate seesaw, including periods of glaciation, hammered humans for 620,000 years. NOT the other way around. No mention of humans hammering the climate.
That’s what this study suggests. But I wonder, did those volcanoes erupt in sync with the Laschamps magnetic reversal? Because if they did, then the magnetic reversal was actually the real culprit.

“The fossil record shows no drastic changes in plant or animal life,” says this article on SOTT. I beg to differ.
When it erupted about 74,000 years ago, Indonesia’s Toba supervolcano may have triggered a 1,000-year episode of ice sheet advance, and a short-lived “volcanic winter” that drastically reduced the human population at the time.
