Have something dump collossal amounts of CO2 in the atmosphere starting around 1000CE and have 1500CE be a desertified nightmare world.

Cool warming twist PTTG.
Another twist with weather is a world were the monsoons that where typical of Africa tens of thousands of years ago returned in the Medieval period. The effects would depend on how strong they were.
Weak monsoons that brought rains a short distance into North Africa could greatly strengthen the cultures of the Magreb and make the Corsairs, already a serious problem to the late Medieval and Early Modern West, into a civilization ending threat.
Strong monsoons that could create vast lakes and grasslands could also threaten to directly connect Europe with topical Africa's microfauna. Thus making Europe's population far less stable and radically limiting European agriculture at a highly vulnerable period.
