Tang dynasty and Mayan civilization doomed by climate change?

A German study suggests that climate change, c600-900 AD, may have led to the downfall of both the Chinese Tang dynasty and the central-American Mayan civilization. More specifically, there might have been "a general shift towards a drier climate at around 750 and then, during these generally drier period, three-year cycles in which rainfall was very low," leading to poor harvests and peasant revolts.

Too bad they can't blame this on SUVs.
