Comet theory false; doesn’t explain cold snap at the end of the Ice Age, Clovis changes or mass animal extinction

Comet, Meltzer, SMU, Clovis, boundary layerControversy still rages over what sparked climate change at the end of the Ice Age 12,800 years ago, including a theory it was caused by a comet hitting the Earth.

As proof, proponents point to sediments with deposits they believe could only result from a cosmic impact. A new study disproves the theory, said lead-author and archaeologist David Meltzer, SMU. Continue reading
