Horror! This Comet almost Destroyed Earth just 13,000 years ago

Around 12,800 years ago, a massive climate change occurred on Earth which started an Ice Age that lasted another 10,000 years, just as our home planet was recovering from one. The event is called Younger Dryas and it caused a temporary reversal of climate warming after the Last Glacial Maximum (an ice age that lasted 1,00,000 years) started receding. The Younger Dryas event has always puzzled the scientific community due to the spontaneity and erratic nature of the event. It is understood that such an event could not have been caused simply as due course of nature and an external interruption had to be behind it. Recently, researchers have found large evidence for one such possibility - a comet strike. The new evidence of a comet impact also suggests that before the ice age came firestorm and massive destruction of life on Earth.

The study of the Younger Dryas event also tells us that a similar comet strike is possible in the future and what kind of an impact would it cause in present times. According to Melott, if the event that took place 13,000 years ago repeated itself in modern age, it would deplete the Ozone layer causing increase in skin cancer, make food sources scarce, and force humans to adapt to harsher climate conditions overnight causing a decline of the population.

The research has been published in The University of Chicago Press Journals and sheds light on the Younger Dryas event that has been a confusing time period for geologists worldwide. There have been two popular theories around the event, Laacher See volcano eruption and Impact Theory. The findings from this research points out that the Impact theory of a comet strike is the more plausible explanation for the ice age event. What’s scary is that
