Are there any serious predictions that the planet will become uninhabitable, even a little bit? People can live in a huge range of climates, far more extreme than global warming predictions. Plants also grow well in high temperatures and with artificial irrigation, don't require regular rainfall.
Parts of the world currently inhabitable will become unlivable. In particular, Dubai, which is one of the most inhospitable places I've ever been on earth (combination of humidity + high temperature) - becomes lethal by 2100 in some projections - http://edition.cnn.com/2015/10/27/world/persian-gulf-heat-cl...
Hot temperatures are much more difficult to handle than cold temperatures for humans. With proper clothing/goggles/face masks, I've been downright cozy at -43 celsius in northern British Columbia - spent hours completely comfortable. In Dubai, on a hot, humid day in September, I can manage maybe 15 minutes of exertion before I have to escape back to air-conditioning.
So a city that runs on oil revenue and has literally no natural attractions becomes the equivalent of death valley. Meh. Let's pick a different worst case scenario...
Not just the city. Pretty much all of northern Africa and the Arabian peninsula become uninhabitable. Can you find another 17839048.21 km² to replace it?
