Professor Says Mayan Calendar Does Not Portend Earth's Doom (2012AD)

Mike Baillie's tree ring data indicate worldwide catastrophic events at the following dates: 3195BC, 2354BC, 1628BC, 1159BC, 540AD and smaller events at 207BC and 44BC.

I believe we've seen this before. Where, I don't know?

"An Impact Event in 3114BCE? The beginning of a Turbulent Millennium."

Here, I fixed the title. Gotta be politically correct now.

When did the Mediterranean Sea break through the Bosporus Straits to fill the Black Sea? The mass migration caused by that would surely have wreaked havoc throughout Europe. And even earlier question is when did the Mediterranean break through the land bridge from Gibraltar to North Africa? That was an even bigger upheaval to the people living in the low-lying, fertile, and warm area that is now the bottom of the Mediterranean Sea.

This is quite poorly written.

Comet impact
A comet impact in AD 536?
Emma Rigby1, Melissa Symonds2 and Derek Ward-Thompson2

Emma Rigby, Melissa Symonds and Derek Ward-Thompson review the evidence for the possibility that a comet may have impacted the Earth in historical times, and discuss the size of the putative comet.

Abstract

A global climatic downturn has previously been observed in tree-ring data associated with the years AD 536–545. We review the evidence for the explanation of this event which involves a comet fragment impacting the Earth and exploding in the upper atmosphere. The explosion would create a plume, such as was seen during the impact of comet Shoemaker-Levy 9 with Jupiter. The resulting debris deposited by the plume on to the top of the atmosphere would increase the opacity and lower the temperature. We calculate the size of the comet required, and find that a relatively small fragment of only about half a kilometre in diameter could be consistent with the data. We conclude that plume formation is a by-product of small comet impacts that must be added to the list of significant global hazards posed by near-Earth objects.
