One of the many unknown and unforseeable ways in which the climate crisis might play out is that different countries have different imperatives.
As temperatures rise, countries like Russia might well be net winners, as their frozen lands thaw out and become viable for agriculture.
When/if carbon capture becomes a reality, we'll have something of a global thermostat. What sort of wars will ensue to decide who gets to tweak the thermostat and whether it is turned up or down?
