And you have a recognized pulse of meltwater at that time as the last of the glaciers collapse into the sea called Meltwater Pulse 1b, round about 11,600 years ago. So this is a period which is very tightly defined. It's a period when we know that human populations were grievously disturbed.

That's when the so-called Clovis culture of North America vanished entirely from the record during the Younger Dryas, and it's the time when the mammoths and the saber-toothed tigers vanished from the record as well.

The abrupt cessation of the global meridional overturning circulation, of which the Gulf Stream is the best known part, And the main theory that's been put forward up to now, and I don't dispute that theory at all, is that the sudden freeze was caused by the cutting off of the Gulf Stream, basically, which is part of the central heating system of our planet. So no wonder it became cold.

But what's not really been addressed before is why that happened. Why? gulf stream was cut why a sudden pulse of melt water went into the world ocean and and it was so much of it and it was so cold that actually stopped the gulf stream in its tracks that's where the younger dryas impact hypothesis offers a very elegant and very satisfactory solution to the problem now

The hypothesis, of course, is broader than that. Amongst the scientists working on it are, for example, Bill Napier, an astrophysicist and astronomer. They have assembled a great deal of evidence which suggests that the culprit in the Younger Dryas impact event or events was what we now call the torrid meteor stream, which the Earth still passes through twice a year.

It's now about 30 million kilometers wide. It takes the Earth a couple of days to pass through it on its orbit. It passed through it in June and it passes through it at the end of October.

The suggestion is that the Taurid meteor stream is the end product of a very large comet that entered the solar system round about 20,000 years ago, came in from the Oort cloud, got trapped by the gravity of the Sun and went into orbit around the Sun, an orbit that crossed the orbit of the Earth. However, when it was one object, The likelihood of a collision with the Earth was extremely small.
