People didn't have enough to eat because of that.

Because they weren't getting nutrition, their immune systems got weak, and they became susceptible to opportunistic diseases.

And then in 542 A.D., you had the Justinian Plague, which came in and wiped out, some estimates are, half the population of Europe.

And this is what led into the Dark Ages.

And it was not until this warming, global warming, that took place between 900 and 1000 AD that the population of the world began to increase again because people were now, you had now, agriculture was much more, you know, much more viable than it had been during the Dark Ages because we can go back into our historic accounts and

Describing that months at a time, they couldn't see the sun, right?

Eventually, all that cleared off.

In fact, there was a flourishing wine industry in Britain, even up to Scotland, which was

at the end of the medieval warm period, that the wine industry in Northern Europe collapsed.

But so for about 300 years, 350 years, you had this warming, according to some estimates, was even a degree warmer on average than now.

But because of the abundant...

food that people were eating, population rapidly expanded.

In fact, the stature of Northern Europeans even increased by three to four inches.
