Black Plague Caused Climate Change

A new study suggests that the devastating Black Death may have done more than wipe out 1/3 of the population. It may have triggered Europe's "Little Ice Age" in the 14th century.

A team from Utrecht University, Netherlands, which studied pollen and leaf data, reports that the millions of trees that began to grow on abandoned farmland may have changed the climate by "soaking up carbon dioxide from the atmosphere."
