It seems like the Middle East is going to get a double whammy from climate change.
1. Their economies will be affected as the world moves to non-oil based energy.
2. Their land will become more uninhabitable as time goes on. Higher temperatures, less water, more sandstorms, etc. I've seen studies that say the Middle East will be completely uninhabitable by the end of the century so we should expect mass migration from there to other places.
They will need money to combat number 2, but they will have less of that because of number 1.
80% of Dubai's food is imported, so can you label it already uninhabitable? Habitable is just a matter of how many resources you're willing to pump into making it so. With the holy sites in the middle east, it will remain populated for long to come.
You're right though, we'll see unprecedented mass migration. What's worse is the middle east has some of the highest birth rates in the world. With that excess population and constrained resources it is inevitable there will be continued conflict.
3. During the cold war most middle-east countries sided with the USA. They were perceived as the allies. Now it's becoming increasingly harder for those countries to enjoy western support.
