Catastrophe also holds a fascination wherever in time it may happen and that certainly holds true for the Younger Dryas Impact Hypothesis.
About 12,800 years ago, global temperatures plunged and the ensuing cool period lasted over 1,000 years.
Much ink has been spilled over the years wrangling over the cause of this momentous event was it a sudden freshwater surge spilling out of a lake, was it volcanoes, was it a solar super flare … or was it the one that appeals most to popular imagination an impact with a comet or asteroid?
Well, a new study gives weight to the latter idea and finds new evidence that yes indeed, there was a cosmic impact at the beginning of the Younger Dryas event.
