Cite? Graphs I've seen show it could take as little as a thousand years at an
8 deg. C rise, even if poorly understood melting acceleration processes are
not included.

"Models for continental ice melting are not yet capable of capturing the
complex features that NASA satellites are now discovering in these ice fields.
Important processes may be missing from models."

"Instead of melting slowly, like a giant ice cube, ice in Greenland and
elsewhere seems capable of melting much more rapidly. Reports back from the
field are noticing disturbing trends in this regard."

The IPCC working group 1 Tech Summary mentioned those and rejected
them.

It is in the sea level rise section that the report gave the 20 degree
C requirement for melting the Antarctic Ice Sheets over millennia.

You really should read it.
