Approximately 14,000 years ago, the unprecedented solar event—now judged to be the most powerful known to have occurred—marked Earth’s transition into the Holocene epoch, according to the findings of an international team of scientists.
The team traces the event to around 12,350 BC using a new climate-chemistry model specifically designed to reconstruct ancient solar particle activity. This expands the known timeline for ancient solar storms and raises the bar on the upper boundaries of their intensity.
Although the event in question was already known from past observations of radiocarbon spikes in ancient wood samples, its scale and magnitude remained unknown.
Now, thanks to a unique model employed by researchers at the University of Oulu in Finland led by postdoctoral researcher Kseniia Golubenko and Professor Ilya Usoskin, the ancient storm is recognized as being 18% more intense than the next strongest solar event of similar character, which occurred in AD 775 based on data from tree-ring data.
The discovery was made possible by the team’s specially designed SOCOL:14C-Ex model, which also showed the extremity of the event from 14,000 years ago compared with the most powerful solar storms of recent years.
“Compared to the largest event of the modern satellite era — the 2005 particle storm — the ancient 12,350 BC event was over 500 times more intense, according to our estimates,” Dr. Golubenko said.
Golubenko notes that the scale of such storms in the past reveals the potential that storms of similar magnitude could occur again. The impact such solar activity might have on modern infrastructure, including satellites, electrical grids, and communication systems, could be vastly underestimated.
“This event establishes a new worst-case scenario,” Golubenko said.

(excerpt) The Younger Dryas impact hypothesis suggests that a comet or asteroid impact, likely around 12,800 years ago, triggered the Younger Dryas cooling period and other significant environmental changes. This hypothesis proposes that the impact caused a sudden drop in global temperatures, contributed to the extinction of megafauna, and influenced the shift to agriculture in some regions.
Elaboration:
Younger Dryas:
This is a period of abrupt cooling that occurred around 12,800 years ago, interrupting a warming trend and causing a significant drop in global temperatures.
Impact Hypothesis:
The Younger Dryas impact hypothesis suggests that a comet or asteroid impact was the primary driver of this cooling period.
Evidence:
Proponents of the hypothesis point to the presence of unusual materials, like iridium and platinum, in sediment layers from the time period, suggesting a cosmic impact.
Consequences:
The Younger Dryas impact is thought to have caused:
Extinctions: The impact is linked to the extinction of large mammals like mammoths and cave bears.
Climate Change: It is believed to have triggered a sudden cooling period, with temperatures dropping by as much as 10°C in some regions.
Cultural Shifts: The impact may have contributed to changes in human populations, potentially leading to the decline of some cultures and the rise of new ones, like the shift to agriculture.
Ongoing Research:
The Younger Dryas impact hypothesis is still being researched and debated, with new evidence and analysis continually emerging.

A comet impact 13,000 years ago might have wiped out megafauna

this can't be right - we're told climate chemistry models show that the Sun has little to do with our climate, compared to gas powered vehicles, coal burning power plants, etc.
So the headline says it was 500 times more intense than any previous event and the story explains it was 18% more intense than an event in 775 AD?

Here’s a link that works:
Humans were still cavemen when this occurred!
So the holocene megafauna extinction was an event and not due to ecosystem collapse caused anthropogenically? Imagine that.
OR, Humans were still cavemen BECAUSE this occurred!
I don’t think a lot of folks don’t comprehend the recent events of the ice age. Geologically speaking, on a timeline of the earth…the ice age “just ended.”
My geology professor said if you are thinking in geology terms, the ice age would be an ice cube that had been sitting on your counter for about 15 minutes. Much of it would be melted, but you could still tell there was an ice cube there.
The environment isn’t getting hot for the first time in its “life.” It is going back to normal. Humans are merely along for the ride.
OR, Humans were cavemen BECAUSE this occurred!
When we went on an Alaskan cruise we were bombarded with Climate Propaganda about the glaciers retreating.
I asked, “Well how do you suppose the folks there felt when the glaciers were advancing?”
They didn’t have an answer for that one.
You don’t need an ice age for that.
Colossal Biosciences is currently attempting to bring back extinct species, including woolly mammoths and dire wolves, by editing the DNA of closely related living animals. They are focusing on de-extinction through genetic engineering, rather than cloning, using the DNA of extinct species to modify the genomes of extant animals like grey wolves (for dire wolves) and Asian elephants (for woolly mammoths).

Clovis folk may have been wiped out, then replaced long afterwards by Siberian/Asian/other walkers and sailors.
Detroit was under a mile high sheet of ice.
It does and there were a couple of theories about causes. One was this one, a solar event. The other is an asteroid or comet impact event.
Not really. They were likely in small hunter gatherer communities; some learning about growing stuff. The ice age killed off a bunch of people. But in the temperate zones things were going along just fine.
The cooling period of the Younger Dryas would have killed any crops because the impact was felt all over the world, not just in the higher latitudes. This is why the impact theory seems to make some sense to people.
That action would have caused a significant decline in population…and that was the period where humans sought shelter in caves. But the cave paintings of the time showed intelligence and a higher thinking process. The fact that someone was “thinking about hunting”, and found the tools and the light source, then went into a cave and put them on the wall; and then “showed them” to other humans takes a level of intelligence and socialization that goes beyond “cavemen.”
Personally, I welcome the coming ice age. I always wondered what woolly mammoth tastes like…
