I suspect that there will be a serious breakdown because of resources in various places. We are already seeing it in Africa as a result of spreading dessication which leads to war. The next place to suffer will be the sub-continent because there are too many people and not enough water. I would expect Europe and North America to be relatively less impacted due to the lower population levels with the proviso that they will be faced with waves of immigrants and neither place has any coherent plan for dealing with them.
Then there is the middle east where, eventually, someone will develop an atomic bomb and use it on the shia or sunnis and then the shit will really hit the fan.
