I don't think that's fair. Other countries have made considerable progress at getting to their climate goals, although there's an argument that those goals weren't set high enough or near enough. As much as China is still an environmental trainwreck they've made impressive progress on air pollution.

Because the US is such a huge polluter, I think a US administration that was seriously interested in dealing with climate change and willing to say no to billionaires would make a meaningful difference. We've seen investment in "green" do well for other countries, and even here to a lesser extent.

I suspect that climate change will do tremendous damage to our civilization, and that any global conflict which takes place as that damage progresses will only exacerbate things. The damage caused by climate change will certainly bring about new conflicts as well. Billions of climate refugees will be forced from their homes and need to go somewhere, and even the places they try to flee to will be hit with natural disasters and feel increasing pressure as once heavily populated areas will become less habitable due to heat, desertification, fire, flooding, storms, a lack of drinking water, etc.

I think that however dark the times ahead are, our actions right now will matter, and that's especially true if we just admit defeat and accept powerful people making the situation much worse by plundering and hording as much as they possibly can.
