Its a pretty reasonable argument. The entire point of human rights is that states can’t break them and they are risking the lives of billions with every bit of increase in CO2 they allow to occur. Given they have signed up to treaties to not do so and are still carrying on suggests that they are performative in saying they will act while not doing so. The crack downs on protests around climate change have been shameful but I guess after 4 decades of inaction politicians just don’t want to hear people screaming at them since they never intend to act.
