Are you now claiming that climate change isn't a big deal because the billions of people whose homes are flooded, or too hot to survive, or otherwise uninhabitable can just...go somewhere else?

In today's world, we see (much smaller) groups of people trying to relocate as their homes become intolerably dangerous. The press calls it "the refugee crisis" and it's causing massive tension all over the world. What do you think will happen if the flow of refugees continues increasing, year after year, for decades?
