Yes, models aren't 100% accurate and there are uncertainties, please answer how does that justify your assumption that they somehow underestimate future warming? It's not a fair assumption to make, since warming tends to track middle-of-the-range estimates, climate models in previous ipcc reports neither systematically overestimated nor underestimated warming over the period of their projections.

Climate policy changes have already reduced projected warming from >4c to <3c by the end of century. That's a current policy scenario, it's even lower if you count in pledges and commitments.
