説明
<jats:title>Significance</jats:title> <jats:p> A 1,112-y tree-ring record of moisture shows that in opposition to conventional wisdom, the climate during the rise of the 13 <jats:sup>th</jats:sup> -century Mongol Empire was a period of persistent moisture, unprecedented in the last 1,000 y. This 15-y episode of persistent moisture likely led to a period of high grassland productivity, contributing fuel to the Mongol Empire. We also present evidence that anthropogenic warming exacerbated the 21st-century drought in central Mongolia. These results indicate that ecosystems and societies in semiarid regions can be significantly affected by unusual climatic events at the decadal time scale. </jats:p>
