Scholars in many disciplines have used diverse methods and sources to establish that, between the 15th and 18th centuries, a Little Ice Age considerably cooled Earth's climate. In four particularly chilly periodsthe Sporer Minimum, Grindelwald Fluctuation, Maunder Minimum, and Dalton Minimumfalling temperatures both caused and reflected changes in atmospheric circulation that altered regional patterns of precipitation. Many scholars have argued that weather in these cold periods provoked or worsened regional food shortages, famines, rebellions, wars, and outbreaks of epidemic disease, in ways that may have contributed to mass mortality across the early modern world. More recently, some scholars have contrasted the fates of societies or communities that were vulnerable to climate change with those that were resilient or even consciously or unconsciously adaptive in the face of the Little Ice Age. Overall, research that connects climatic and social histories has suggested that human decisions, political structures, economic arrangements, institutions, and cultures either magnified or mitigated the impact of climate change on the societies of the early modern world.
