A huge asteroid may have hit the Earth 12,800 years ago causing global climate change and extinction, according to new evidence found in South Africa.

Or not.

This conflicts a wee bit with the Laurentide ice sheet.

As to whether humans alone or climate change caused the megafauna extinction, I'm an "all of the above" guy:

1. People were here feasting on large animals.
2. A comet hit, causing massive climate disruption.
3. Times were pretty desperate. People finished off the megafauna.

Humans can be amazing survivors.

[Opinionated Blowhard]

I love how the Daily Mail has a couple artist renditions of how an asteroid could have smashed into Earth and a scary massive asteroid hurtling toward Earth.

[plain talk]

Randall Carlson is a big believer in this theory.

[The Louiswu]

12k years is virtually nothing in terms of time, the Earth could still be feeling long term effects from such a strike.

[null and void]

In our orbit around the galactic center we cross dust lanes about every 12,000 years.

They’re not just dust, they’re dust, gravel, rocks, boulders, and the occasional mountain.

Mostly we miss the mountains, they are few and far between.

Hopefully we’ll miss the boulders the next time...

And the Sasquatch, with their warm fur, prospered through the ice age.

[Pearls Before Swine]

Another form of “Global Reset.”

I was watching a show about exoplanets, with scientists discussing whether or not an alien species might be looking at Earth and wondering if it is habitable for them.

One scientist commented that it’s possible, but they might likely pass on Earth because, with large quantities of ice at both poles, we would rightly be considered in an ice age!

I was both shocked and pleased by his honesty!

[T. Rustin Noone]

Wait.

What?

12,800 years ago we were emerging from the last Ice Age. Was
there another Ice Age that they did not tell us about during the Holocene Climate Optimum?

[ChessExpert]

“Another theory was presented by American scientists in 2007 – that the cooling was triggered by the dust fallout of an asteroid impact.”

Why is this a different theory?

[higgmeister]

What does not kill you, makes you stronger.

[Openurmind]

Whoops... How about that. Exactly what “pseudo-archaeologists” Graham Hancock and Brien Foerster have been stating for years now... In fact almost to the very year this new discovery indicates.

[Ciaphas Cain]

I have a friend whose longtime professional research has been about the Younger Dryas. Fascinating stuff!

[chrisser]

Wait a minute - I thought all climate catastrophes were caused by SUVs...

[xzins]

Catastrophism

Re: "Extinction Level Events"

Complex life forms and almost all major animal groups began to appear in the fossil record between 540 million and 515 million years ago.

Since then, several meteors, several mega-volcanic events, and at least one glacial event (445 million years ago), came close to wiping out most land animals, and sometimes aquatic animals, too.

In addition, there were probably dozens of smaller local events that wiped out most life across thousands of square miles.

Life in our universe is fragile, and quite rare, I think.

Unfortunately for them, the current ice age has been in effect for 4 million years.
