Here's the scenario that gives me the willies: Wet bulb temperatures in South Asia and the Persian Gulf reach dangerous or outright fatal levels. Depending on the location, two degrees of warming is enough. This alone results in the displacement of hundreds of millions of people. That it would happen in India is very worrying because of the tensions with Pakistan, and the danger of nuclear war between the two states. As for the Gulf, well, that area is not exactly stable even today. So what happens if several hundred million people relocate, while at the same time different lower-key consequences of climate change such as rising sea levels, increasing storm damage and the economic upheaval of having to give up fossil fuels contribute to instability and international tensions? Europe went nuts with the Syrian refugees we got recently, a real crisis will topple governments. Will we somehow rally and discover a co-operative spirit in ourselves, that will let us manage the various crises peacefully through treaties and diplomacy? It sure doesn't seem like that is the kind of political paradigm that's being built now. Not to put too fine a point on it, how do we avoid WW3 in the above scenario?
