… Central Asia's river civilizations, research shows

"The Aral Sea basin in Central Asia and the major rivers flowing through the region were once home to advanced river civilizations which used floodwater irrigation to farm.

The region's decline is often attributed to the devastating Mongol invasion of the early 13th century, but new research of long-term river dynamics and ancient irrigation networks shows the changing climate and dryer conditions may have been the real cause.

Research led by the University of Lincoln, UK, reconstructed the effects of climate change on floodwater farming in the region and found that decreasing river flow was equally, if not more, important for the abandonment of these previously flourishing city states…"

I blame caveman-made climate change for the end of the Ice Age, what with all the campfires roasting mastadon meat and all!!

Let's just say that Genghis didn't help things.

If only they'd embraced solar and wind power, or even foot power like the Flintstones and Rubbles did in the TV show by the same name.

Most irrigation systems collapse due to salinization of the soil. Of course drought will speed up the process.

If only they adopted a carbon cap and trade system and switched to alternative fuel sources.

It wasn't drought. It was all the bodies Genghis used to block the rives.

Ha!Ha!….

You mean climate change isn't always caused by human activity?

Anybody with a brain knows that climate change can have many causes, most of them unrelated to humanity, as they happened frequently before humanity existed. The current climate change, however, is 99.975% manmade – the debate on that is no longer open unless you are a believer.
The sheer fact that a catastrophic fall of a civilization – that we had connected to no less then a razing by Ghengis Khan – happend due to a comparatively minor natural climate change, should be telling. Well, should. Actually…

That sermon done, reading the article they do not deny that it was Ghengis Khan that cut down the civilization – they just state that the dryer condition prevented a buildup AFTER he went through, and that after the Arab invasion of the 8th century Central Asia recovered quickly, while having a more favourable climate.

In short: It WAS Ghengis that razed these civilizations, and either he was more thourough then the Arabs or the climate did not allow a reconstruction (probably both).
