What is happening in North America in 1453CE
In the South-West of the present-day USA, a long dry spell has had a disastrous impact upon the agricultural societies of the Hohokam and the Anasazi. Many farming villages have been abandoned and people have moved away from their historic homelands.
Climate change may also have been responsible for changes in societies of the east. There has been a marked upswing in violence between communities, and urban centres such as Cahokia have been abandoned. Other centres continue in being, though none are on the same scale as before.
The Norse settlements on Greenland have vanished, possibly victims of a colder climate and of the continued Inuit expansion across the Arctic region.
