such as me, thinks that one meter is certain, but as much as 25 meters is possible by 2100 (more importantly, so does NASA's Hansen). Too many highly non linear guns in the face (methane, albedo). The planet is going to try to trsnsfer heat to the poles with even more enthusiasm, so melting is going to accelerate.
