If you look at the big picture one things that stands out is regional rural to urban migrations. I put a lot of immigration in that context. 90% of rural to urban migration is internal and 10% spills over. There are currently huge internal migrations inside of Africa, but some percentage heads to Europe usually following expat family members. So in a way we already have refugees not from climate change but from industrialized agriculture.
