I have zero confidence that existing political structures can solve this problem. So much so that I view any political attempts at addressing climate change as a net increase in carbon emissions (because it is a waste of energy).

Even if a carbon tax was implemented in some countries, emissions would just move to countries with no tax. The only way to enforce it on a world-wide scale is war. War would emit so much carbon that it would defeat the purpose of enforcing carbon taxes.
