**Climate-driven changes in Mediterranean grain trade mitigated famine but introduced the Black Death to medieval Europe**

"_Here, we argue that a post-volcanic climate downturn and trans-Mediterranean famine from 1345–1347 CE forced the Italian maritime republics of Venice, Genoa and Pisa to activate their well-established supply network and import grain from the Mongols of the Golden Horde around the Sea of Azov in 1347 CE. This climate-driven change in long-distance grain trade not only prevented large parts of Italy from starvation but also introduced the plague bacterium to Mediterranean harbours and fueled its rapid dispersal across much of Europe._"
