Exploring abrupt climate change and pandemic induced by comets and asteroids during human history
The cruel irony of this welcome movie should be apparent to Tusk regulars. A satirical blockbuster uses an impending comet impact as a plot device to communicate a deeper message to the planet that no one listens to scientists who....warn us of climate change. The director reveals his subtext in many interviews, and calls it here, “...the most thinly disguised metaphor in the history of metaphors.”
As the Taurid meteor season wanes on the approach of Thanksgiving, I thought it was relevant (and economical) to share a couple of recent videos which present the Taurid phenomena from different, but mutually informative contexts. The first is a ‘live shot,’ and the second is a ‘retrospective,’ if you will.
In wake of Halloween last week a very, very scary scientific paper was published. "Widespread glasses generated by cometary fireballs during the late Pleistocene in the Atacama Desert, Chile," creates a rebuttable presumption that horrific cosmic airbursts -- without leaving craters -- have indeed occurred in human history, a central contention here at the Tusk.
The post Comet fragment airburst melts, whips and glasses Chilean desert sands during Younger Dryas appeared first on The Cosmic Tusk.
The trust-but-verify ancient history crowd was devastated last month by the passing of indefatigable YouTube science communicator Charles Appleton. I took it hard like many. But I feel particularly sorry upon his death, and a bit guilty. Not long before Chuck died, I responded to a tweet from LasVegApps with this: WTF?! Have you run […]
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 […]
