More on climate change and the decline of the Maya

Filed under: Uncategorized — Andie @ 3:34 pm

The National Geographic reports on another theory about the fall of the Maya due to climate change:

In the 19th century, when explorers began discovering the overgrown ruins of “lost cities,” theorists imagined an immense volcanic eruption or earthquake or superstorm—or maybe an empire-wide pandemic. (Related: “Maya Mystery Solved by ‘Important’ Volcanic Discovery?”)

But today scientists generally agree that the Maya collapse has many roots, all intertwined—overpopulation, warfare, famine, drought. At the moment, the hottest field of inquiry centers on climate change, perhaps of the Maya’s own doing.

The latest Maya climate-change study, published Friday in the journal Science, analyzes a Belizean cavern’s stalagmites—those lumpy, rocky spires on cave floors—to link climate swings to both the rise and fall of the empire.
