The Younger Dryas —
How Much Do You Know?
12,900 years ago, Earth was dragged back into the ice. A warming world went cold almost overnight. One of history’s greatest climate mysteries — six questions to see if you’ve got the answers.
The Event That Stopped the Thaw
Around 12,900 years ago, Earth was emerging from the last Ice Age. Glaciers were retreating. Temperatures were rising. It looked like the planet was finally warming for good.
Then — almost overnight in geological terms — it reversed. Temperatures plummeted. Ice sheets returned. An entire civilisation of prehistoric humans was caught in the freeze.
Was it caused by melting ice sheets disrupting ocean currents?
A cosmic impact — fragments of a comet hitting Earth?
Or something we still don’t fully understand?
The Younger Dryas remains one of the most debated periods in human history — sitting at the intersection of climate science, archaeology, and alternative history.
Take this quiz and discover how much you really know.

🎲 More QuizzesThe Younger Dryas Ended Faster Than It Began
The Younger Dryas lasted approximately 1,200 years — but its ending was even more dramatic than its beginning. Some scientific studies suggest temperatures in certain regions may have risen by 10°C or more within just a few decades, possibly even within a single human lifetime. In geological terms, that is barely a blink. What could cause a climate system to flip so fast? That question still has no fully agreed answer.
