Did mammoths, sabre-tooth tigers and other Ice Age megafauna face a similar, impact-induced fate to the dinosaurs? That’s ...

In the Northern Hemisphere, the Younger Dryas cooling occurred between 12.8 and 11.7 ka BP. This cooling is thought to have been the result of an abrupt change in atmospheric and oceanic circulations.

At the end of the Pleistocene period, approximately 12,800 years ago — give or take a few centuries — a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger ...

(Santa Barbara, Calif.) — Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth’s atmosphere 12,800 years ...

Cosmic “touchdown airbursts” — explosions of comets or asteroids above Earth’s surface — may be far more common and destructive than previously thought, according to new research. Unlike ...

(Santa Barbara, Calif.) — Touchdown airbursts — a type of cosmic impact that may be more common than the crater-forming, dinosaur-killing kind — remain somewhat less understood. UC Santa Barbara Earth ...

The end of thePleistocene, marked by the Younger Dryas (YD) onset around 12.8 thousand years ago, witnessed the sudden extinction of many North American megafauna and the collapse of the Clovis ...
