Did a series of droughts precipitate the collapse of the Khmer Empire in the early 15th century, for example? Or was the Little Ice Age in the mid-17th century a leading cause of the rampant warfare in Europe, China and the Ottoman Empire?

Many scientists caution that a much hotter earth or catastrophic weather event could tip the balance in unforeseen ways. The Intergovernmental Panel on Climate Change Fifth Assessment Report says there is “justifiable common concern” that climate change will increase the risk of armed conflict in some situations, even “if the strength of the effect is uncertain”.
