Study Suggests Climate Change-Induced Drought Caused the Mayan Collapse
pigrabbitbear writes "The collapse of the Mayan empire has already caused plenty of consternation for scientists and average Joes alike, and we haven't even made it a quarter of the way through 2012 yet. But here's something to add a little more fuel to the fire: A new study suggests that climate change killed off the Mayans."
In different climates the biological succession works the other way. For instance, right now, in New England, if you leave bare rock undisturbed, it starts growing lichens. The lichens eventually trap enough material to make the wetter spots suitable for mosses which move in next. Then come the grasses, which turn the place into a field. Eventually, the field builds up enough soil that shrubs and pioneer tree species can show up. And finally, the larger canopy trees move in, and you have a forest again. This process actually happened over about 150 years, as the farming that used to happen in New England moved westward leaving land behind.

In other words, a planetary climate change contributed to the fall of the Maya. Which just goes to prove a point: climate is NOT a fixed value, but a variable with a substantial-enough range to cause major ecological changes in relatively short periods of time. . . .
