That's a bit defeatist, and kind of a whataboutism. Sure, it is the greatest tragedy of the commons in history playing out as a slow motion trainwreck, but you don't solve the tragedy of the commons by continuing to make it tragic "because everyone else is doing it". You focus on your own impact and you also focus on diplomacy with your neighbors. You don't just stop, you put in twice the work.

It's also somewhat easy to shift that viewpoint a little, too, right now: China's emissions numbers have started a rapid deceleration downward. They are doing more about their emissions faster than the US. Does the US want to lose to China that badly that we shouldn't even try to align US policy to more of the emissions reductions that China is already succeeding at today? (Much less their robust plans for future emissions reductions?)
