That says that loss over the past 19 years is 5 meters; that's less than a millimeter per day. You're proposing a melt up to 500 times faster.

That says that the fastest plausible scenario has the ice sheet melting in 1000 years, while the greater likelihood is 10,000 years. And that's if/after we cross temperature thresholds we're not guaranteed to cross.

Nowhere does it entertain the whole thing going in decades. If you have credible sources that argue for the possibility of decades, or even a century or two, you should add that to the page.
