Oh yeah, one of my heroes, Herman Flone, he's one of the godfathers of modern climatology. Let's see what he had to say.

He said, from the viewpoint of, and look at this, this is 1979, from the viewpoint of the climatologist, the most important result of these investigations is the fact that within the human timescale of about 100 years or less, our climate is much more variable than hitherto assumed. Especially important, and indeed disquieting,

is the evidence of abrupt coolings within warm interglacial periods, apparently as rare events with a recurrence interval of 10,000 years. Now, he's talking about cooling events, but the counterpart is warming events, and we're going to see some more of that. Let's go to the next one, Ryan.

So he says the problem of intense, abrupt, intense coolings during an interglacial, which we're in an interglacial, During an interglacial climate similar to the present climate resembles, to some extent, the Damocles sword hanging high above the globe and its inhabitants. Because of its possible consequences for the human race, its study deserves a much higher priority. Now, this was in 1979.

Now, hold on this slide for a second. So what we're looking at here is from Greenland ice cores. If you go down the right-hand column, zero is now. Ten means 10,000 years ago. Over on the left, zero is the ice surface. 1,500 means 1,500 meters down. Now, shifts to the left mean cooling. Shifts to the right mean warming. Okay.

Now, if you look at this, and of course, at one point, as it says here, look, the graph of the last 10,000 years of temperature change as preserved in Greenland ice cores shows temperature constantly and repeatedly warming and cooling 2 to 3 degrees Fahrenheit or more. In fact... Just up from the bottom, you'll see a spike to the left. That's at 8,200 to 8,400 years ago.

That was a spike of cooling that lasted about 200 years. If that happened now, our civilization would be extinct. You would have global agricultural failures. Yeah, okay. And within two years, within two years, we'd have mass famine. Shortly after that, because of weakened immune systems, we'd have pandemic diseases, the whole thing. Humans would survive. We survived that.
