Because of the way the climate and ocean systems respond to heat-trapping emissions, sea levels will continue to rise even after air temperatures stabilize. So, even in a future scenario where the world achieves the stabilization of air temperatures, the Earths oceans and cryosphere (frozen regions like Antarctica ) will continue to adjust.
