I worry that poor countries like my home country, which has not much resource to migrate people in mass, will face serious issues in the near future. Having said that, I also believe in the resilience of the people there. They have been through military dictatorship and whatnot, so I have faith that they will survive albeit with huge cost of lives and property...
Climate change will disturb world's political and economic systems, and I hope (and kind of believe) that the humanity can survive through this ordeal. In my honest opinion, it's too late to stop climate change, and the best we can do is to do our individual parts to mitigate the effects and come up with ways to cope with it the best we can.
