The ice sheet has enough water to raise ocean levels by 20 feet.
It has been losing mass over the past two decades.
Ocean levels are the same as 20 years ago.
Something doesn’t add up.
It would all have to be in the atmosphere. Which kind of defies the water cycle, unless the atmosphere is a hell of a lot warmer than it was 20 years ago.

Only if you leave out the Antarctic ...
Heh, y'think? The Greenland keyword has one, or a few, topics about how many gigatons of ice have accumulated in a short time frame. Inland areas that are below sealevel (Qattara Depression and some other spots in Africa, California's Death Valley and Salton Sea, etc) could become the world's flood prevention basins. The Dead Sea is on the list of course, but flooding that would also drown the Galilee, and beside agriculture, there's plenty of economic activity in those parts. Also, the geographic barriers on both ends are something like 600 meters high.
