And it's this exact problem that will get solved with the immigration from climate change. Europe is going to get more African migrants fleeing climate change.
Yes, this seems inevitable, and given Europe's relative historical contribution to climate change, I think we have a moral obligation to welcome some, as (to some extent) their right, not charity. An issue, however, is that immigrants tend to gather in crowded hot cities near sea-level, just the places we should plan to slowly depopulate, while it's rarer to see African faces in sparsely populated upland rural areas, where there are more empty houses and older people needing services. Research about climate migration focused mainly on where people will move from, not enough about where it would make most sense for them to move to.
A massive investment in adult education would probably help a lot in making up for the Economic problems of importing tons of people without the level of formal education necessary for the higher value added jobs most europeans can do (50% of the population being Uber and food delivery drivers doesn't quite work economically), but the very same people who brought us a massive house price bubble to reward rent-seekers to the max (in turn feeding a fall in birth rates because young people can't afford a family), a race to the bottom on taxing wealth and 4 decades of falling real terms funding for any public services other than the ones mainly used by old people, are hardly going to invest in adult education.
"Immigrants should be forcedguided into places that us superior white people, who are above what I deem menial work, are neededborn-in-country people struggle to live in."
So - think - you really prefer to keep immigrants in overheating floodable crowded cities - ghettoes ?
By the way, I am myself an immigrant, I now live in a village, and do struggle. I also studied climate science and demography and technology trends, so I think about the longer term - places people struggled to live in the past, and the future, are not the same. We should use our knowledge to help those who move gain a better life than otherwise.
