That goes back to 250,000 years ago. That's all the way to the bottom 3000 meters down. That's all the way to the bottom of the Greenland ice sheet. Now this is oxygen isotopes and. And what can cause something like that?

Well, see, you just asked me, that's the question. Yeah. We need to know. Yeah. Now, you can see the spasm that got us out of the Ice Age. There was a massive warming. Then it cooled. That was the Younger Dryas. If we go to the next slide, I think we're zooming in on that. Let's go back. So, like, just how –

Well, yeah, I mean, you think about going back to a full glacial mode compared to now. Yeah. I mean, yeah, you had at the end of the last ice age, you had armadas of icebergs, giant icebergs flowing south along the east coast of the United States as far as Florida. Yeah.

So you go across the peninsula to the other side 12,000, 13,000 years ago, you could see huge icebergs floating to the south, melting as they flow, but But, yeah, I don't think we've seen – I mean, have you seen any icebergs off of – It's been a minute, yeah.

Well, okay, the good question – Now, one of the considered to be the modern analog, the analog for the modern Holocene was the Eemian, right? And the Eemian was apparently a period of extended warmth that was considered to be the analog for the Holocene. But that's the Eemian right there, that huge spike to the... So it's now recognized that the Eemian was a lot more variable than the Holocene.

It's like what it's done is the relative stability of the Holocene has given us this window of opportunity within which we have created modern civilization. If any of that, any of that happened now...

Forget it.

Forget it.

Forget it.

See, one of the things that's frustrated me is, you know, when I was quoting Herman Flone there from 1979, now it's 79, early 80s, when I was reading and learning about this, that, oh, wow, you know, climate has really changed dramatically. So then...
