The Black Death in Europe

The Black Death is estimated to have killed 30% to 60% of the European population. In total, the plague may have reduced the world population from an estimated 475 million to 350–375 million in the 14th century. It took 200 years for the world population to recover to its previous level. William Ruddiman et al. proposed that those large population reductions in Europe, East Asia, and the Middle East caused a decrease in agricultural activity that allowed reforestation to cause additional carbon dioxide uptake from the atmosphere, leading to LIA cooling.
