Dryas

Here’s the central question we’re chasing today.

What actually happened at the start of what geologists call the Younger Dryas? Because something did happen.

That part isn’t in dispute.

The Earth had been slowly warming out of the last ice age for thousands of years.

So the real question we're circling is this: What if the disruption twelve thousand eight hundred years ago wasn't local? What if it was big enough, sudden enough, and widespread enough that it didn't just threaten one group in one valley, but reshaped conditions across multiple continents at nearly the same time? That's the claim we're investigating.

And to understand it, we need to look at exactly what changed, starting with a climate reversal that scientists still argue about today.

The event has a name, the Younger Dryas.

And for people living through it, it may have felt like the world changing its mind.
