This is particularly seen as being a problem in Africa. You can google dozens 
of articles like these:

The desert latitudes have shifted before, during the hotter 1930's when the 
American midwest desertified, and around 1300, when the Anasazi ("cliff 
dwellers") disappeared and the Aztec started migrating into central Mexico. 
The 
phenomenon has been well studied.

In Africa one aspect of the shift is to disrupt seasonal monsoons, so that 
rains that normally go to Ethiopia and Somalia instead flood Mozambique, a 
thousand miles or two to the south. Southeast Asian monsoons will also be 
disrupted, with Indonesia particularly at risk.

Historically these warming/drying trends have been associated with major 
population migrations and worldwide wars and invasions. Hopefully all this 
will 
blow over and we'll have nothing to worry about. Right?
