      It won’t matter if a small area is still habitable. The resolution of 7 billion people trying to fit into a space that fits a fraction of the population will end the species.

      It took less than 1% of the population of Europe moving around to nearly break the EU. Watch what happens when it’s 10 to 20% of everyone everywhere.

              The movement of a tiny group of people relative to the size of the EU drastically shifted the entire political structure of the EU, leading to Brexit and several other countries considering the same. Magnify that affect by the number of people that will be moving due to climate change, and you get an extinction event.

        Will end the current age of civilization? Most definitely.

        Will it end organized societies as we know them? Probably?

        Will the human beings go extinct? Probably not. Its not crazy to think that we’d face a bottleneck of only a few hundred million humans or less. But there are people all across the economic and geographic spectrum who are prepping. The rich will survive at their polar fortresses. The poorer will survive underground, or at high altitudes.

      Once we have nations fighting for water resources (tied directly to food production) it wouldn’t take long before the entire population is at risk

      Ontario’s great lakes have been threatened with receding volume, pollution, and mass algae blooms that show how fragile even that massive resource is

      Ground water across the globe has been mass polluted and drained to nothing in large areas.

      We are a lot more vulnerable than it seems
