Studying Nature's Impact on Ancient Civilization and Tuning In Online to Make Sense of Meteorites

Okmok. In remote Alaska. A strange name and a strange place for what some scientists and historians now say caused the downfall of the Roman Republic and the Egyptian Ptolemaic Kingdom shortly after the demise of Julius Caesar.

Studying Nature's Impact on Ancient Civilization and Tuning In Online to Make Sense of Meteorites

Huh?

A detailed study in the Proceedings of the National Academy of Sciences notes that Mount Etna in Sicily erupted at Caesar’s death in 44 BCE. Some have speculated that this eruption may have resulted in a cold-weather period accompanied by crop failures, famine, and other natural problems. The resulting outcome of all this was civic unrest and violence all around the Mediterranean region. That situation seems intensely familiar as the coronavirus pandemic is a contributing factor of social dissonance and upheavals all around today’s world.

One problem: that eruption of Mount Etna, truly, just wasn’t all that big. Now, a thorough analysis of volcanic debris in Alaska, ash found trapped in Greenland ice cores, tree ring analysis in Europe and North America, and deposits in a cave in China all point to a truly massive eruption of Alaska’s Mount Okmok with worldwide implications.

The volcano let go with a mighty bang about the time Roman senators were too busy assassinating Caesar to take note. Evidence collected from all the locations noted above indicates that 43 BCE and 42 BCE were among the ten coldest years within the past 2,500 years of Earth history. With that, the audience seems to indicate that cold snap likely was caused by the ash and gas unleashed into the atmosphere by Okmok.

Is Earth's Magnetic Field Linked to Atmospheric Oxygen?

The scientists making the observation were surprised. A time series analysis of geological records over the past 540 million years of Earth history seems to show a highly correlated link between oxygen levels in the Earth's atmosphere and the strength of the planet's magnetic field, and both seem to be slowly increasing in sync.

Is Subduction “Infectious?”

Earth’s surface is composed of huge plates of relatively stable continental crust and oceanic crust that are constantly forming and recycling. Where they meet, subduction frequently occurs, with ocean crust plunging beneath continents. Thus oceans open and close, appear and disappear.
