Scientists Say A Comet Crashed On Earth And Caused A Huge Fire 12,000 Years Ago

It was long thought that the Ice Age was over when a huge comet came slamming down in chunks onto Earth around 12,800 years back and started enormous flames, the impact of which dove the planet into another cool period and drove numerous creatures into a phase of extinction.

Researchers have already imagined this situation and now new research has discovered proof. Two studies in the Journal of Geology depict tests taken from ice and from sediment that go down the effect driven environmental change, an icy period known as the Younger Dryas. As per the researchers, synthetic investigation of the samples taken from many locales throughout the world, proposes enough flames broke out to cloud the sky and shut out the sun, which would have prompted the around thousand-year frosty time.

“The hypothesis is that a large comet fragmented and the chunks impacted the Earth, causing this disaster,” researcher Adrian Melott said in a statement from the University of Kansas. “A number of different chemical signatures — carbon dioxide, nitrate, ammonia and others — all seem to indicate that an astonishing 10 percent of the Earth’s land surface, or about 10 million square kilometers, was consumed by fires.”

Millenniums passed and the planet started to warm up once more, “people again emerged into a world with fewer large animals and a human culture in North America that left behind completely different kinds of spear points,” explained the university.

A considerable measure of substantial North American creatures were strangely wiped out together around 11,000 years back, including saber-toothed cats, wooly mammoths, ground sloths and mastodons. The situation the researchers portray could offer a clarification for their vanishings.

As per the researchers, the comet that broke into the pieces that sprinkled down on Earth would have initially been around 62 miles crosswise over and what stays of it is as yet flying around the solar system.

“Computations suggest that the impact would have depleted the ozone layer, causing increases in skin cancer and other negative health effects,” Melott said. “The impact hypothesis is still a hypothesis, but this study provides a massive amount of evidence, which we argue can only be all explained by a major cosmic impact.”
