So, 4 years till we definitively get there? That honestly sounds worse because this was a hypothetical, we absolutely cannot stop our emissions to any meaningful degree if we want to continue living in a society.

And even if we magically did stop all direct emissions, there are secondary warming processes that have started and cannot be stopped. The oceans absorb a quarter of all CO2 which they will start to outgass once the atmosphere concentration stops increasing. The melted glacial masses have reduced the planet's reflectivity, increasing the greenhouse effect. Permafrost thawing is causing methane releases, etc.

> Bashing the developing world is not helpful. The US account for a massive chunk of historical emissions and excess consumption.

Oh my bad, do keep doing it until all the fish are completely gone and we all starve to death because dumb people did things centuries ago. Yes the developed world has an obligation to assist in all ways possible to make sure progress and development can continue in a clean and sustainable way, but past crimes don't condone present ones.

I mentioned China here specifically since they're an outlier in the topic, with vast ocean going fishing fleets emptying stock in even less developed countries that need it, i.e. Indonesia, Africa.
