> They produce the most emissions

Oh yeah well your country produces more emissions than Vatican City. Since absolute emissions are bad, no matter the size of the country, your country sucks too. Every country that isn't in last place for emissions sucks! Get your emissions down to Vatican City levels otherwise you're just as bad as everyone else /s

> are not amenable to international plans to reduce emissions

Please tell me more about this. They're actually flattening or reducing emissions. They signed the Paris agreement.

> Want to see the ourworldindata graph (again, probably)?

That graph tells me North America and Europe combined produce the nearly the same as China. That means if they go 0 carbon tomorrow, it's like taking out one China's worth of emissions. Is that futile?

North America and Europe have also emitted way more cumulatively than China. Historic emissions are the cause of problems today.

Here's another ourworldindata graph: https://ourworldindata.org/grapher/cumulative-co-emissions

If you tell me "historic emissions" don't matter then I have to ask, where is the line? Do China's emissions yesterday also not matter? That's historic too, right?
