Here's an uncomfortable question: What happens when citizens of cities impacted by global warming decide they want (rightfully so) to move to somewhere more habitable? Wouldn't that disrupt the global economy? Wouldn't a large sudden migrant situation disrupt the host country? Wouldn't the world become more volatile as the new "oil" emerges: renewable electricity and water? The upside is that there will be more green nuclear plants but to get there I see troubles ahead. The situation in Ukraine and heat problem in Middle East and Africa facing famine. All of this feels like it's snowballing to a potentially unmangeable situation.
