History: Climate changes resulted in war & famine in preindustrial Europe (1500 & 1800).rebellions, revolutions, & political reforms followed

Climate Change Caused Angry Runts : Discovery News: "“The mild cooling in Europe in the late 18th and 19th centuries brought about an upsurge in prices, social disturbance, war, and migration but not demographic crisis, because of social buffers such as cross-continental migration, trade, and industrialization.”

The researchers conclude that the economic downturns caused by climate change were the direct causes of the human crises. When a country's economy and agricultural output didn't suffer, their populations didn't either.

“This result explains why some countries did not undergo serious human crisis in the Little Ice Age: Wet tropical countries with high land-carrying capacity or countries with trading economies did not suffer a considerable shrinkage in food supply, nor did some countries, such as New World countries with vast arable land and sparse populations, experience substantial supply shortage,” the researchers wrote.

Although technologies and economies may have advanced since the 16th century, humanity's connection to fluctuations in the Earth's climate are not limited to the past."
