Twelve thousand years ago, give or take a klick, there was a huge land which was below sea level.
It was very warm and very fertile. It was protected from the sea by a solid block of land many miles across.
But over the years that land block became smaller and smaller. Today, we would blame global warming and people driving SUVs. But there weren’t many SUVs back then.
Finally the land block collapsed and a wave came larger than any seen since came in all at once. It was unimaginably large. Within months thousands, yes I said thousands, of square miles were inundated. We do no know how much of it was coverd in a matter of days by the first titanic wave.
Today that once-fertile valley, easily large enough to put a sizable country in, is called the Black Sea. The Black Sea has several hundred feet of river water on top, but the rest of the way down it is still the heavier sea water, the salt water that came across in the first giant wave.
And a Kyoto Treaty would not have stopped it.
