文摘

•: We modeled effects of climate and vegetation change on lake water δ¹⁸O in the Maya area.
•: Past shifts in vegetation cover fail to fully account for changes in lake water δ¹⁸O.
•: Model results reveal late Holocene rainfall variability in the Maya Lowlands.
•: Model results indicate protracted aridity between 1500 and 800 cal yr BP.
•: The period of intense aridity is associated with Classic Maya cultural decline.
