The bring it back is also incorrect. Once emission stop completely things still get worse for 20 years or so due to lag, then, assuming no new tipping points carry us further, things may stabilize. If tipping points are reached, then we keep sliding down the slippery slope until we either find a new stability node or there is no one left to care. 4°C, 6°C? We don't yet know, but I guarentee we'll find out.
