Climate changes of 535-536 (535–536 AD), sudden cooling and failure of harvests, perhaps caused by volcanic dust; 900–1300 Medieval Warm Period, wet in Europe, arid in North America, may have depopulated the Great Plains of North America, associated with the Medieval renaissances in Europe Great Famine of 1315–1317 in Europe
In northern Peru and central Chile climate change is cited as the driving force in a series of migration patterns from about 15,000 B.C. to approximately 4,500 B.C. Between 11,800 B.C. and 10,500 B.C. evidence suggests seasonal migration from high to low elevation by the natives while conditions permitted a humid environment to persist in both ...

[4] As such, A Temperate Empire demonstrates that debates about climate change and humanity's role in changing the climate extend back well before the modern era.
climate change costs, costs for nature and landscape, costs for water pollution, costs for soil pollution and; costs of energy dependency. Use of cars for transportation creates barriers by reducing the landscape required for walking and cycling. It may look like a minor problem initially but in the long run, it poses a threat to children and ...
