NASA Data Peers into Greenland’s Ice Sheet

I ran the calculation a few years ago. I worked with the current area of the oceans with the new volume of ice melt on top. I got a nine meter rise, which is in the vicinity of 27 feet. I didn't figure the volume of the space surrounding the oceans; however, a 27 foot rise does not go very far inland in most places.

Florida would be completely submerged, and New Orleans wouldn't need to worry about hurricanes any longer.

Seacoast cites the world over would be gone.

Now, those alarmist folks need to consider a few things. Greenland is a really big place where most of the ice mass is way north. Temperatures have not ever risen anywhere near the melting point. The higher temperatures experienced in the southern regions really are not so unusual. Remember, the Vikings called the place "Greenland" because it surely was when compared to Norway.

That ice sheet isn't going anywhere for a very long time. I read somewhere that the southern portion of the sheet is getting thinner while the northern region is getting thicker.

Except, much of that land mass is significantly below sea level; as much as 3,500 meters.

That is a major chunk of the ice. It is more like an iceberg that got grounded on an underwater mountain range.

The drawing seems to show it is in a large bowl with a rim that extends above the water level. The ice below has already been accounted for in current sea levels, hasn't it?

There is plenty of ice that would cause trouble if melted, but no where near as bad as they tell.
