~~I don't know this David, but fuck them.~~
Next time I'll read the article before knee jerking. As it turns out, they don't say it's too late to act, rather that it's too late to still count on changes from the political and economical domination structures.
Leaving the rest here because it's still true.

Climate change isn't an on/off switch, it's something that can always be made better or worse by increments.

Yes we're going over 1.5°C and almost surely over 2°, world is gonna become hell for hundreds of millions of people (usually those least responsible for climate change) as it has already for dozens millions.
But we're still better at 2.2 than 2.3. Or at 3.7 than 3.8. Or 3.0 than 3.1.
Humanity's survival is not at stake, but the lives of countless people are. If by our action we can reduce the number of people sufdering/dying from climate change even by 0.0001%, it's still worth the fucking fight.

TLDR: never too late to go vegan, stop traveling by plane or bombing oil companies exec offices and cars.~~
