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

The ~335 AD Hopewell Airburst Event in Ohio

American cosmic airburst in late Roman times revealed by University of Cincinnati

Meteorites, silicious vesicular melt glass, Fe and Si-rich magnetic spherules, positive Ir and Pt anomalies, and burned charcoal-rich Hopewell habitation surfaces demonstrate that a cosmic airburst event occurred over the Ohio River valley during the late Holocene. A comet-shaped earthwork was constructed near the airburst epicenter. Twenty-nine radiocarbon ages demonstrate that the event occurred between 252 and 383 CE, a time when 69 near-Earth comets were documented. While Hopewell people survived the catastrophic event, it likely contributed to their cultural decline. The Hopewell comet airburst expands our understanding of the frequency and impact of cataclysmic cosmic events on complex human societies.

  1. This well and truly puts the cat amongst the anthropologist pigeons, not to mention the old guard anti-impact in human history crowd.

    Their professional paradigms are collapsing under the weight of new scientific evidence.

    They are all the last of their kind that everyone else in scientific professions just wish they would get around to dying already so real, new, exciting and professionally rewarding science work can be done.

  2. My post about this on an Ohio Valley cultures(Adena) site was removed as pseudo science.

  3. And now the journal Geology is reporting multiple airbursts over the Atacama desert during the Younger Dryas.

    Airbursts that formed massive slabs of melt glass at >1600C!

    We live in interesting times.
