China is the world's biggest C02 producer and has declared it has no more concessions to make. Yet the world is content to watch America fall further into debt & inflation as climate-focused regulations impact logistics, energy & manufacturing. In sum, the US is destabilizing, risking social disorder, for a goal its competitors will not meet.
For example, US coal supplies are the lowest they've been in decades at a time when domestic energy demands are requiring about 16% more coal than last year. Similarly, the backlog at California ports is largely due to environmental regulations enacted by the CA legislature (truck emissions primarily).
Putting this imbalance in national security context... Resources China & Russia could be allocating to climate change are instead directed to offensive hypersonic weapons, nuclear launch capabilities & forward deployed bases. The US is scrambling to match these investments and innovations in a more expensive labor/procurement environment & while facing all manner of distractions declared national priorities, yet having nothing to do with real security.
