Recent studies estimate climate warming is happening faster than it was, ballpark +0.3C per decade.

As we are at or nearing +1.5C now, with global emissions at an all time high [ perhaps peaking soon ] theres a good chance we are headed toward +2.6C by ~2060.

Keep in mind the CO2 stays up there for a long time, centuries, so when we get to net-zero its max-CO2 and therefore max-heat.

does it stop? the more co2 the more heat is retained. so the relation between co2 and temperature is an integral over time. were we suddenly to stop burning things how far does it go up before infrared emissions equilibrate with the larger thermal flux? that and the lower albedo and other knockoff effects may continue to make things worse even if we were to stop.
