Serious addendum: Sweden, Norway and Finland have population densities lower than Brasil, and I think we should all expect to take in at least 100 million climate refugees during the next few decades. Another reason why we need to keep the countryside communities alive.
@Loukas Why do you need to keep rural communities alive for this? Migrants move to the cities whenever they have free choice; build extensive housing in the capitals, not in places that have not much housing demand and are full of people who want to keep their white villages white.
@Alon I don't think it's possible to scale up the present five small cities of Sweden, Norway and Finland to fit an extra 100m people.
@Loukas @Alon And there is nowhere near enough agriculture capacity for 100m people. Even tripling current population to 60 million seems impossible. Maybe by getting rid of all cattle that could be done but not with 100m...
@lotneuv @Loukas Europe exports food, as we're seeing with the Ukraine grain deal - and global warming means higher yields here and lower ones elsewhere.
@Alon @Loukas Not necesserily. Climate change doesn't increase the amount of light. Violent rains can ruin harvests in minutes at least locally. Plant diseases and insects are moving North too. I think that even keeping current yields is not at all guaranteed. Alle that and ofc we'll loose large parts from Southern european crops.
