The IPCC estimates a likely upper bound for sea level rise, for instance, at about a meter, but under much stronger warming scenarios.

This would get us to 600 ppmv by 2100 (all other things being equal), around the same as IPCC «scenario + storyline» B1 or A1T, with warming by 2100 of 2C (rather than 4C as predicted using the exponential curve).
