Canon

•
When the Medieval Warm Period ended, the civilizational structures built on its surplus collapsed — the environment giveth and the environment taketh away
The transition to the Little Ice Age after 1300 removed the agricultural surplus that had sustained medieval civilization. Famine, plague, and social upheaval followed — the environment that had enabled growth now constrained it.

Highlights

•
The Medieval Warm Period created the agricultural surplus that funded cathedrals, universities, and Crusades
Warmer temperatures extended growing seasons, opened marginal land to cultivation, and increased crop yields. The resulting surplus funded everything from Gothic cathedrals to the first universities to military expeditions to the Holy Land.
