Yes there is enough H2O around the planet to raise sea levels by 20m.  Probably 200, even 400. coo.

In the last 15000 years sea levels have risen by 110m, as the ice caps melted. The current rate, 3m per 1000 years, would be an indiscernible blip on this graph.

Sea ice is little of a problem since it displaces 90% of its volume so melting it would make only a small variation.

Sea ice actually is no problem. When it melts it shrinks to fit into the 90% space that was already underwater.

Sea level is rising at 0.2m per century. New research suggests it could be 3.0m per century by the end of this century.

The Earth is presently in an interglacial period which began about 10,000 years ago. But greenhouse gas emissions over the past 200 years have caused climate changes that are faster and more extreme than experienced during the last interglacial. This means past rates of sea level rise provide only low-end predictions of what might happen in future.

 

We examined data from the last interglacial, which occurred 125,000 to 118,000 years ago. Temperatures were up to 1℃ higher than today - similar to those projected for the near future.

 

Our research reveals that ice melt in the last interglacial period caused global seas to rise about 10 metres above the present level. The ice melted first in Antarctica, then a few thousand years later in Greenland.

 

Sea levels rose at up to 3 metres per century, far exceeding the roughly 0.3-metre rise observed over the past 150 years.
