The sea level rise of the past century is a record for 6000 years. (That is when the melting of the ice age ice sheets finished.)

Even if we stop pumping out greenhouse gas, the Earth will continue getting hotter for quite some time due to the greenhouse gas we have already pumped out. That's ignoring the possibility that positive feedback effects will release more. And it will take centuries for the effect of that heat to finish melting all the ice it is going to melt.

We will have to lower the greenhouse gas level substantially below the present level to get the ice to stop melting.
