COP is a greenwashing conference for the imperial core countries to make false promises and try to rationalize how their plans to do everything in exactly the same way but with more funding for NGOs will solve the problem.
Capitalism itself is incompatible with addressing climate change and therefore so is "reform" within it. It does not factor human well-being into its equations, let alone caring for the wider climate over decades, and climate change is caused by industry, transportation, and war, all of which it will relentlessly maximize in pursuit of profit. It also controls the state. Attempts at direct action and the use of "civil society" result in the criminalization of the former and the cooption of the latter. COP is an example of the latter, it's where the NGOs line up for a crack at false catharsis for a few million in funding.
To fight climate change, we must band together, educate each other, and stay disciplined in our fight against the real engine of climate change, capitalism.
