When the Earth Suddenly Stopped Warming

[@eons]

Hi all! A quick correction: at 9:17, our temperature conversion graphic mistakenly converts the temperature difference as an absolute temperature. A change of 10°C is equivalent to 18°F.
We apologize for the error and a big thanks to VUQuadrophenia for pointing this out to us!

What is interesting is the name for the volcano: Laacher See. It is named after the abbey close by, Maria Laach. But Laach itself means lake, and See means lake too. Basically, it's the lake's lake.
As a small addendum: The Latin name of the abbey, the one in the deed of foundation, is Abbatia ad Lacum, Abbey at the Lake, from which the German name is derived from. And the lake is the Lake of (Maria) Laach, the Lake of the Abbey at the Lake. This makes this the Abbey at the Lake of the Abbey at the Lake of the Abbey at the Lake of the Abbey at the Lake...

I quite like how Blake's face just scrunches up at the awful puns y'all make him say. As a punster it's just very satisfying to see the "oy" !

Proponents of the impact theory think the comet fragment or meteorite hit the North-American ice sheet. So the primary impact left no crater.
With the impact theory you still get all the effects like the influx of fresh water and shutting down of the ocean current but adds a little more devastation to account for the mass extinction.
Thanks for doing this episode. The YD event, whatever caused it, has very much shaped the world we live in today. Essentially we still live in the aftermath.

Thank you! I have been waiting for an episode on this topic for awhile.

[@NicholasHay1982]

I love your episodes about plants, and I would love to see more of them!

Steve, wherever you are, just know that you'll always be my favourite hominin... 😔

Data from GISP2 brings back memories. I was on that expedition!

I think it's interesting that agriculture started just after the Younger Drias. Somehow after the temperature got up, people made some changes.

I like how PBS acknowledges the lands where many of the fossils they bring into topic are from. It’s nice to see them add those endings as of lately, but it’s also important that we don’t forget where many scientific discovery have been found in recent years.

There are candidates for impact sites on the ice sheet. A few places being looked at. Also air bursts could easily have generated enough heat.

10:06 It was never their land, nomads have no concept of land ownership or even permanent settlements.

[@thangri-la]

But that's because the belief is that it cannot be owned. People are free to move around. The Iand is "communal" in a sense. Now some people come in, "take" this supposedly common land (quite illegal in the nomadic philosophy) and the nomads's share in it and restrict their movement. I call the argument you propose the argument of the thief. The same thing as people stealing public goods.

[@jamesmatthew1903]

@@thangri-la A thief you say? Because imo, the man who tills the land to sew crops has the stronger claim vs nomads. Farming is what makes our way of life superior to that of the nomad. And when I say superior, I mean able to feed more people per unit of work.

I really appreciate the recognition of the indigenous be people and their land. They are often forgotten. It is important to me that they and their land is recognized.
