Exploring abrupt climate change induced by comets and asteroids during human history

UCSB Press Release

From a University of California – Santa Barbara Press Release:

In the entire geologic record, there are only two known continent-wide layers with abundance peaks in nanodiamonds, impact spherules, and aciniform soot. These are in the 65-million-year-old Cretaceous-Paleogene boundary layer that coincided with major extinctions, including the dinosaurs and ammonites; and the Younger Dryas boundary event at 12,900 years ago, closely associated with the extinctions of many large North American animals, including mammoths, mastodons, saber-tooth cats, and dire wolves.

“The timing of the impact event coincided with the most extraordinary biotic and environmental changes over Mexico and Central America during the last approximately 20,000 years, as recorded by others in several regional lake deposits,” said Kennett. “These changes were large, abrupt, and unprecedented, and had been recorded and identified by earlier investigators as a ‘time of crisis.’ “

  1. Well, one can say that science is finally finding out what the Maya and the Hopi Indians have known for centuries. The Popol Vuh gives the whole event in great detail while Mary Miller and Karl Taube were the first to identify where all those meteorites came. from, way back in 1998 or so.

    Wunderbar. Our scientific studies are finally verifying what the Maya, and the Hope always knew, and even India and how about Ireland? The data about the event has been around for centuries.
