Thanks to Trump and to a lesser extent all other presidents of the US, 4C here we come my 2100 :( If not for Trump we would probably still hit 3.5C. 1.5 is a forlorn dream, and probably was a dream when it was decided upon.
Based off the downvotes I receive on here I think I'm too much of a collapsenik for the average HN poster, but one benefit of being neurotic is that by the time people finally start reckoning with the current state of collapse, I have already made peace with it. The downside is that I become miserable to talk to.
And we need a diverse set of baseline estimates — yours and worse, not just mine and better — so some of us survive whatever nonsense the next 75 years brings.
(I'm also a pessimist about many other things besides carbon).
I'm more ambivalent about CO2 than just about anybody, but I'd go to war over that concentration.

I think this is why the US is trying to annex greenland.
The electricity grid is going emissions free faster than the transportation infrastructure. So the emissions from the production of both gasoline & electric vehicles are going down quickly.
- millions of miles of electrical lines - millions of sq ft of parking lots - wastewater management infrastructure - sewage infrastructure - high municipal debt to service all of the above
