This is fundamentally a massive coordination problem. Sovereign states are really good at solving coordination problems when there is the will. For climate change there will be no consensus to act and it will not be fast enough. If you could manage close coordination just 1-2% of population who would be willing to act, it could change the course of history without violence in few years. Core group would generate enough gravity to attract maybe 10-15% of the population to the cause willing to act to some level. It seems very unlikely. I doubt there is even that 1-2% of people who are willing to drop their life and really push for a change.
