The sediment core showed a reduction in charcoal -- and thus fire -- in the area during the Little Ice Age, a time of global cooling that began sometime between that A.D. 1200s and 1500s and ended in the early 1800s. A new study led by Powers suggests the Little Ice Age led to a worldwide reduction in fires after 1500, and that reduction was not caused by decimation of New Word populations by European diseases in the wake of Columbus.
