Maya May Have Caused Civilization-Ending Climate Change


Self-induced drought and climate change may have caused the destruction of the Maya civilization, say scientists working with new satellite technology that monitors Central America's environment.

More than a hundred reasons have been proposed for the downfall of the Maya, among them hurricanes, overpopulation, disease, warfare, and peasant revolt. (Read "Maya Rise and Fall" in National Geographic magazine (August 2007).

But Sever, NASA's only archaeologist, adds to evidence for another explanation.

"Our recent research shows that another factor may have been climate change," he said during a meeting of the American Association of the Advancement of Science in Boston, Massachusetts, earlier this month.

One conventional theory has it that the Maya relied on slash-and-burn agriculture. But Sever and his colleagues say such methods couldn't have sustained a population that reached 60,000 at its peak.

The researchers think the Maya also exploited seasonal wetlands called bajos, which make up more than 40 percent of the Petén landscape that the ancient empire called home.


Empire? hmmm.

This is interesting as it helps peel away more of the Mayan onion.
