The question isn't where the point of no return is - we've been beyond those the whole time. The question is how bad we want to let it get. Ever fraction of a degree extra warming means worse impacts.
Agree that less than +2°C is unlikely (though not completely impossible). But still, better that than +2.5°C, etc.
