Doggerland

As recently as 6500 BC, Great Britain was connected to Europe!  And if you go back further in your time machine, you'll see a huge plain called Doggerland between Britain and Denmark.

Why?  Because the sea level is lower during ice ages.  More water is in the polar ice caps and glaciers!

The last ice age, the Wisconsin glaciation, reached its peak a bit before 18000 BC.  Back then, there were huge ice sheets going down to the Great Lakes and the mouth of the Rhine.  The north of Britain was covered with ice, and the south was a polar desert!

The light green stuff in this map shows the land a bit later, in 16000 BC.  Back then Doggerland was a wide undulating plain full of complicated meandering river systems.

As the ice age ended, the sea level rose rather quickly.  Doggerland shrank to the medium green stuff in 8000 BC and the dark green stuff in 7000 BC.  One of the last parts to survive was the Dogger Bank.  You can see it on the map if you look close.  It was an island until 5000 BC.

A new theory says that Doggerland was flooded by a huge tsunami around 6200 BC, thanks to a submarine landslide off the coast of Norway!  It's called the Storegga Slide.  There's geological evidence of sediments washed up onto land then.  Maybe an earthquake triggered a catastrophic expansion of methane hydrates underwater.

This tsunami would have devastated a rich hunting and fishing ground populated by Mesolithic humans.   People of some sort have lived on the British Isles, on and off, for much longer!  There are flint tools dating back to 815,000 BC.  These would not be made by Homo sapiens, since our species only came into existence around 250,000 BC. 

But there were Homo sapiens in Britain by 40,000 BC, before the last ice age.  And when the ice age ended and treeless tundra slowly turned into forests of birch trees, more of us moved in.  Instead of eating reindeer and wild horses, the ancient Britons started eating pigs, elk, deer, wild boar and wild cattle - hunting them with ever more sophisticated stone tools.  So by 6200 BC, when the tsunami crashed over Doggerland, there would have been lots of people living quite well.

Puzzle 1: Why is it called "Doggerland"? 

Puzzle 2: What's a "dogger"?

Puzzle 3: When did people start building Stonehenge - how does that fit into the chronology here?

Interesting read:

"To reverse climate change, our society requires something beyond today’s renewable energy technologies. Fortunately, new discoveries are changing the way we think about physics, nanotechnology, and biology all the time. While humanity is currently on a trajectory to severe climate change, this disaster can be averted if researchers aim for goals that seem nearly impossible."
