About 23 feet.

Quote: " For example, if the Greenland ice sheet were to completely melt and the meltwater were to completely flow into the ocean, then global sea level would rise by about seven meters (23 feet)"

A recent study has shown that the existing warming (if we stopped producing GHGs today) would result in about a foot of sea level rise, but that is only about 3% of the total ice mass in greenland.

There isn't really a "point of no return" though. Everything regarding climate change is a matter of degree. Each incremental increase in GHGs means an increase in global temps and that will translate into incrementally more damaging climate results.

That is why it is important to continue working and to do everything that we can to do better and minimize the cumulative effects.
