More evidence is coming in to support the claim that something big smacked into the earth ~10800 BCE, triggering the abrupt reversal of the global warming that was ending the Ice Age and ushering in a cold period known as the Younger Dryas period. We recently found an impact crater buried under the Greenland Ice Cap that may date from this age, though that still needs to be verified. But now this:

Major cosmic impact 12,800 years ago: Geologic and paleontological evidence unearthed in southern Chile supports the theory that a major cosmic impact event occurred approximately 12,800 years ago

Controversial from the time it was proposed, the hypothesis even now continues to be contested by those who prefer to attribute the end-Pleistocene reversal in warming entirely to terrestrial causes. But Kennett and fellow stalwarts of the Younger Dryas Boundary (YDB) Impact Hypothesis, as it is also known, have recently received a major boost: the discovery of a very young, 31-kilometer-wide impact crater beneath the Greenland ice sheet, which they believe may have been one of the many comet fragments that impacted Earth at the onset of the Younger Dryas.


Now, in a paper published in the journal Nature Scientific Reports, Kennett and colleagues, led by Chilean paleontologist Mario Pino, present further evidence of a cosmic impact, this time far south of the equator, that likely lead to biomass burning, climate change and megafaunal extinctions nearly 13,000 years ago.


"We have identified the YDB layer at high latitudes in the Southern Hemisphere at near 41 degrees south, close to the tip of South America," Kennett said. This is a major expansion of the extent of the YDB event." The vast majority of evidence to date, he added, has been found in the Northern Hemisphere.
