Thursday I wondered if climate changes had caused the collapse of civilizations in the past and hey presto! Konrad A. Hughen, a real scientist, comes forward the next day with the claim that the Mayans were done in by a century long dry trend from roughly 700 AD to 800 AD. And if that isn’t enough to make you sit up and take notice, notice the dates. Yep, the Canadian prairie had a distinct dry period starting in 700 AD – the very same time as the Yucatan. Abrupt global climate change, prior to the age of industrialization? Alert Hans Blix!

Thanks to Juan Gato for the heads up (I’d say link, but I linked to a source I liked better).
