For decades, scientists have been studying the cause of the Younger Dryas, and trying to figure out if something like it could happen again. And it turns out that what caused this event is the subject of a heated debate.

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...

"Platinum is rare on Earth, but it's more common in meteorites." Strictly speaking, there is just as much platinum on Earth than in meteorites, it's just that it's almost all concentrated in our planet's iron-nickel core, which separates it from surface geological processes.

It’s just like what is called “rare earth elements/minerals.” They aren’t necessarily “rare,” just highly dispersed over vast areas or concentrated in hard to access areas.

"Hey! That flower just sprouted." "That would be a younger Dryas."

Shoutout to you guys for putting that acknowledgement about the indigenous peoples of the Americas on your video.

0:08 : Where have I heard that name...? 0:47 : aaah... 1:02 : OOOH so THAT's why is called that way!

[@JaniceLHz]

Me too!

[@ArborScientiae]

Hey, I wrote my paleoclimatology term paper on thermohaline circulation and the Younger Dryas, thanks for the throwback!

[@tacticalultimatum]

OMG as a channel islander its great to have a shout out. Fun fact, the plant shown in the image of the north coast of Jersey is Hottentot fig, a prevalent invasive species

[@fersacristan8716]

Was I the only one who have noticed that there is an old painting of marine reptiles behind the narrators?

[@NicholasHay1982]

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

[@markholton8555]

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

[@dang1099]

As always great content! I really appreciate you slowing down a little bit when you speak. Thank you.

[@johnwalters1341]

Always enjoy your videos. Another possible topic for a show would be fossil reefs through time--not only (hexa)corals, but also tetracorals, archaeocyathids, rudists, etc.

Love you all at PBS Eons so much

I love this channel, have been binging it a lot ever since I found it! Always fascinated

13 thousand years ago. Isn't this the same time that it was estimated the Clovis people went extinct? Hasn't it been hypothesized that a comet impact ended a lot of things in North America among the Clovis people?

[@Mojabi_ghost]

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.

[@Evan-rj9xy]

The outro will never feel the same without Steve :(

[@BenLavallee1]

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.

[@Miamcoline]

One of the most astonishing and interesting yet. Well done.
