“Ship of Fools” Captain Chris Turney at UNSW claims to have recognized a local weather disaster 42,000 years in the past, brought on by a interval of photo voltaic minima, intense cosmic ray bombardment, and the collapse of the Earth’s geomagnetic area.
Earth’s magnetic area broke down 42,000 years in the past and prompted large sudden local weather change

The world skilled a couple of centuries of apocalyptic circumstances 42,000 years in the past, triggered by a reversal of the Earth’s magnetic poles mixed with modifications within the Solar’s behaviour. That’s the important thing discovering of our new multidisciplinary research, printed in Science.
This final main geomagnetic reversal triggered a collection of dramatic occasions which have far-reaching penalties for our planet. They learn just like the plot of a horror film: the ozone layer was destroyed, electrical storms raged throughout the tropics, photo voltaic winds generated spectacular gentle reveals (auroras), Arctic air poured throughout North America, ice sheets and glaciers surged and climate patterns shifted violently.
Throughout these occasions, life on earth was uncovered to intense ultraviolet gentle, Neanderthals and big animals often called megafauna went extinct, whereas fashionable people sought safety in caves.
Due to the coincidence of seemingly random cosmic occasions and the intense environmental modifications discovered around the globe 42,000 years in the past, we’ve known as this era the “Adams Occasion” – a tribute to the good science fiction author Douglas Adams, who wrote The Hitchhiker’s Information to the Galaxy and recognized “42” as the reply to life, the universe and every little thing. Douglas Adams actually was onto one thing large, and the remaining thriller is how he knew?

Geological archives report a number of reversals of Earth’s magnetic poles, however the international impacts of those occasions, if any, stay unclear. Unsure radiocarbon calibration has restricted investigation of the potential results of the final main magnetic inversion, often called the Laschamps Tour [41 to 42 thousand years ago (ka)]. We use historical New Zealand kauri bushes (Agathis australis) to develop an in depth report of atmospheric radiocarbon ranges throughout the Laschamps Tour. We exactly characterize the geomagnetic reversal and carry out international chemistry-climate modeling and detailed radiocarbon relationship of paleoenvironmental data to analyze impacts. We discover that geomagnetic area minima ~42 ka, together with Grand Photo voltaic Minima, prompted substantial modifications in atmospheric ozone focus and circulation, driving synchronous international local weather shifts that prompted main environmental modifications, extinction occasions, and transformations within the archaeological report.

Sadly the complete research is paywalled, however I believe we get the thought.
I requested Dr. Willie Quickly about this paper. He’s very doubtful in regards to the suggestion that cosmic rays considerably affect international local weather, the date for the Laschamp occasions (41,000 yr geomagnetic anomaly), relationship of the kauri bushes, and claims that the collapse of the Earth’s geomagnetic area led to the destruction of the ozone layer.
Chris Turney’s different efforts embrace his unwell thought of ship of fools expedition which acquired caught within the Antarctic international warming, and a few fascinating dying penguin theories.
