Widespread evidence of cosmic impact documented – likely cause of the Younger Dryas cool climate episode

Watts Up With That?

From the University of California – Santa Barbara some paleoclimatology without the need to see hockey sticks.

Comprehensive analysis of impact spherules supports theory of cosmic impact 12,800 years ago

(Santa Barbara, California) –– About 12,800 years ago when the Earth was warming and emerging from the last ice age, a dramatic and anomalous event occurred that abruptly reversed climatic conditions back to near-glacial state. According to James Kennett, UC Santa Barbara emeritus professor in earth sciences, this climate switch fundamentally –– and remarkably –– occurred in only one year, heralding the onset of the Younger Dryas cool episode.

The cause of this cooling has been much debated, especially because it closely coincided with the abrupt extinction of the majority of the large animals then inhabiting the Americas, as well as the disappearance of the prehistoric Clovis culture, known for its big game hunting.
