Doesn’t it seem odd that comets can “shed” for thousands of years? Really - they must be making new material...

A thousand-year freeze that began in 11,000 B.C. may have been caused by thousands of atomic-force chunks from a disintegrating comet, a British scientist said. The fragments, each hitting with the force of a 1-megaton nuclear bomb, triggered fires that covered whole continents and filled the atmosphere with smoke and soot that blotted out the sun, said Bill Napier, a professor at Cardiff University Astrobiology Center.

A better explanation is:
This was also at the same time of the gigantic zeta-pinch aurora that could have profoundly altered climate as well as have resulted in many of the same features (such as widespread burning and formation of nanodiamonds) as the comet-encounter that left no crater.

11,000 B.C. What a coincidence. That’s the year Helen Thomas started working for UPI.
