Local Researcher Says New Paper Builds Support For Concept Of What Led To Mass Extinction Of Plants, Animals In North America 12,800 Years Ago

Scientists have been puzzled for centuries about what caused the sudden cooling of the earth some 12,800 year ago, a change so dramatic it led to the extinction of some plants, and animals in North, and South America.

A new scientific paper co-authored by a longtime UC Santa Barbara researcher provides new support for a controversial theory that an asteroid debris field caused a major climatic change over the course of a year.

KCLU’s Lance Orozco reports the research team is finding tiny spheres containing exotic materials not normally found on earth which date back to the time period, which they believe were created by the asteroid debris field.
