That projection was always the very low end of possibilities - the "assume rapid, radical climate action on global level" scenario. Yes, that's a dumb thing to assume.

I hope the optimists are right, it just doesn't look like it to me at all. It…
They are, in fact, included in the projections - we'd be on track to ~2C by 2100 instead of ~3C by 2100 if they weren't. They just aren't that big.
There is no "Make Earth Into Venus Feedback Loop Of Doom" that a lot of people seem to imagine when they hear "feedback loop". There is, however, a dozen of things that add about +5% each.
