I read $SOMEWHERE recently that the the worst case scenario predicted six feet. But that's, IIRC, if we do absolutely nothing, the methane in the Arctic is all released, and Greenland melts. The more likely scenario is somewhere from 1-3 feet.

So unless memory fails me, the article didn't just pull it out of its arse, but a source would've been nice rather than just throw a number out there with no backing whatsoever.

BTW, they already know that a lot of the melting in Greenland is from the bottom up (geothermal) rather than from the top down. But of course you don't hear too much about that, do you?

But it is losing mass when iceberg calving is accounted for.

"Over the year, it snows more than it melts, but calving of icebergs also adds to the total mass budget of the ice sheet. Satellite observations over the last decade show that the ice sheet is not in balance. The calving loss is greater than the gain from surface mass balance, and Greenland is losing mass at about 200 Gt/yr."

Edit: And i thought this article on the scale of a gigaton of water was interesting as well:

Or 0.5mm sea level increase (from your link).

Misreading the link - as many newspapers have done, and it's wrong absent further data - results in 6'

EDIT: As noted by Accipitriform I made the same mistake I pinned on many newspapers.
