Line graph showing estimated temperature variations from 1000 to 2000 CE for the Northern Hemisphere and central England, with three lines representing different data sources. The chart highlights the medieval warm period around 1100-1300 and the Little Ice Age from about 1500 to 1850, followed by a sharp temperature rise in the late 20th century. Temperature is shown as deviations from the 1961-1990 average. — Little Ice Age Estimates of temperature variations for the Northern Hemisphere and central England from 1000 to 2000 ce.

During the Little Ice Age, a climate interval spanning roughly the 14th to the mid-19th century, Europe experienced significant environmental instability that directly contributed to widespread famines.21

The primary drivers of these food crises included:

Agricultural Failure: Frequent cold winters and cool, wet summers disrupted traditional farming cycles. These conditions led to repeated crop failures, including the loss of essential wheat harvests and the ruin of wine production.213
Extreme Weather Events: Specific episodes, such as the "Great Frost" of 1709, caused temperatures to plummet, freezing livestock and destroying crops. The resulting collapse of agriculture forced populations to face severe food shortages, which were often compounded by disease and the inability to transport supplies due to impassable, snow-covered roads.3
Resource Scarcity: Beyond land-based agriculture, the cooling of the North Atlantic led to a decline in cod fisheries, further reducing food security.21
Social and Economic Impact: As food prices rose—sometimes sixfold—hoarding became a major issue, leading to severe social unrest and uprisings among starving populations.3
