What's your best estimate at this point as to when that will be and how much hotter the world will be than in pre-industrial times whenever that equilibrium is reached?
Until we stop adding CO2 and other GHG to the atmosphere that is a moving target. If we had a super plague that killed 90% of humanity before January 2014 then we would probably top out about 2.5C above the pre-industrial era. If we keep burning FF as fast as we can as long as we can until climate change crashes our population then we will hit 4C or perhaps even 6C before we top out for whomever is still alive to care. Our last Climate warning will be when the Northern Hemisphere tips over into the Hothouse while the Southern Hemisphere remains in an ice age interglacial climate. If that doesn't get us to stop then only a mass disaster cutting our population will.
