The USGS says a complete melt of the Greenland ice sheet would raise

that melted, there would be enough ice melt elsewhere to double
that.

Of course, the temperature rise that would do that would cause the
ocean waters to expand enough to raise it another 200 feet or so
putting 80% of the homes in the world underwater.

Fortunately for us, it didn't melt even in periods in history when it
was not only much warmer than now, but also much warmer than anything
currently predicted with any level of seriousness.
