What if Doggerland had survived?

Countries surrounding the North Sea imposed an outsize impact on world affairs. But the sea itself was once land, and might have stayed that way had world temperatures been a degree or two different. Lee Rimmer wonders: What if Doggerland had survived?

The cultural impact of changing the movement of tribal groupings within northwestern Europe would be immediately evident in terms of language. …The languages spoken in modern Doggerland and its neighbouring states may sound vaguely familiar to us, but we wouldn't understand them.
…Doggerland's more sheltered, lower-lying peninsula may have been a more agreeable farming region than the windswept highlands of the British Isles, leaving them with a much lower population distribution. Stonehenge, or something like it, may have been built on the plains of Doggerland rather than Salisbury Plain.

Wild, impossible counterfactuals. My favored parallel-world Doggerland is one that remained as a small island (even now its uplands lie barely feet under the waves). A strange spooky pinewood backwater where the signs are in three languages and the kids speak them all, and where the rain washes the blood leaching from the deep earth.

The (real) Dogger is to serve as the foundations of a vast offshore wind farm, which will provide 4.8GW of sustainable power.
