The reality is Western countries aren’t going to bother accommodating climate refugees. Full on Fascism is still relatively fringe, but when your average person starts to feel the real fear and insecurity from the climate crisis it will be embraced. Walls and detention centers will be expanded, those seeking refuge in the “civilized” world will be met with bullets and gas chambers. There will be no safe havens.
Hot take, but Chris Nolan is the master of making films that feel smart but are actually pretty dumb. He’s like Zack Snyder but he’s good enough at pulling it off that his movies are a hit with critics. People who tend to overestimate their own intelligence will often hold Nolan in high esteem. He’s also a cryptofacist.
