Little Ice Age Global Climate Crisis and Famine of the 1620s

Timeline

1. 1621–1622Northern Europe and Russia · RussiaIn 1621–1622, northern Europe and Russia experienced abnormal cold and short summers, and grain failed to ripen, causing widespread crop failures; Russia, already weak in food reserves after the Time of Troubles, saw local unrest worsen, while northern Europe also faced rising grain prices and wandering famine victims.
2. 1623–1626Holy Roman Empire · GermanyFrom 1623 to 1626, Central Europe faced sustained food shortages under the dual pressures of Thirty Years' War destruction and climatic anomalies; in the mid-1620s many regions reported concurrent crop failures, plague, and famine, with peasant flight and the collapse of local order accelerating, laying deeper foundations for the humanitarian disaster of the war.
3. 1627–1628Shaanxi and North China · ShaanxiIn 1627–1628, Shaanxi, Henan, and other regions of the late Ming experienced alternating droughts and floods; the great drought in Shaanxi in 1627 drove large numbers of famine victims to wander and worsened local order; at the same time Korea and Japan also reported abnormal climate and agricultural difficulties, as East Asia entered the prelude to the larger social crisis of the 1630s.
4. 1629–1630Nodes of the global trade network (Amsterdam, Istanbul, Guangzhou, etc.) · GlobalFrom 1629 to 1630, grain prices rose simultaneously in Europe, West Asia, and East Asia, as the global agricultural decline caused by the Little Ice Age spread through trade networks; around 1630 France, the Ottoman Empire, and the late Ming all reported worsening social unrest, and the global character of the 1620s climate crisis was especially evident in this phase.
