Evidence of a Younger Dryas impact event just keeps adding up, as time goes by. This research paper is from last month's Science Daily.

Quote:African evidence support Younger Dryas Impact Hypothesis

A team of scientists from South Africa has discovered evidence partially supporting a hypothesis that Earth was struck by a meteorite or asteroid 12 800 years ago, leading to global consequences including climate change, and contributing to the extinction of many species of large animals at the time of an episode called the Younger Dryas.

..................

Thackeray's team believes their discovery of a platinum spike at about 12 800 years ago at Wonderkrater is just part of the strengthening view that an asteroid or cometary impact might have occurred at that time.

This is the first evidence in Africa for a platinum spike preceding climate change. Younger Dryas spikes in platinum have also been found in Greenland, Eurasia, North America, Mexico and recently also at Pilauco in Chile. Wonderkrater is the 30th site in the world for such evidence.

"Our evidence is entirely consistent with the Younger Dryas Impact Hypothesis" says Thackeray.

The discovery in South Africa is expected to be integrated with those made in other parts of the world, recognising that the source of the platinum at Wonderkrater could hypothetically be cosmic dust that was dispersed in the atmosphere after a meteorite impact in Greenland.

The probability of a large asteroid striking Earth in the future may seem to be low, but there are thousands of large rocks distributed primarily between Jupiter and Mars. One in particular, classified as Apophis 99942, is referred to as a "Potentially Hazardous Asteroid." It is 340 meters wide and will come exceptionally close to the Earth in 10 years' time.

"The closest encounter will take place precisely on Friday April 13, 2029," says Thackeray. "The probability of the Apophis 99942 asteroid hitting us then is only one in 100,000, but the probability of an impact may be even higher at some time in the future, as it comes close to Earth every 10 years."

The true purpose of democracy is not to select the best leaders — a clearly debatable obligation — but to facilitate the prompt and peaceful removal of obviously bad ones.

Yeah, that one has been known for over a year now, and there is speculation about that one and the Y-D Impact event being related. The problem is that there is no evidence of its age..........yet.

Its entirely possible that both Impactors are directly related to the same event. My guess is that all this is related to the sun, because comets have this terrible habit of swinging too close to the sun. Once they enter the inner system the gravitational effect of the sun breaks the comet into lots of objects that find a new orbit, which our planet has a bad habit of entering as it swings around the sun.
