Of course they will be. That's just what happened during the Syrian civil war; the refugees were welcomed with open arms in Europe, Germany didn't experience any political turmoil that reverberates to this day at all.

I guess I'm in a sarcastic mood today. Yes, of course that will cause mayhem. It's one of the reasons I see climate change as such a threat to our all civilization. We're fearsome tribal creatures and the coming waves of desperate peoples will almost certainly play into the hands of nationalist fearmongers and firebrands.

I wonder if we will see some kind of -literally - ecofashism rise from that.
