Where is they citation of Al Gore claiming the arctic will be ice free? Everything in that source is prefaced with terms like "could Be" and "as soon as", which you seem to be interpreting as a complete certainty. If I said I had cancer and could die as early 2018 then I wouldn't be wrong on New Years day 2019.
Where's the citation of the Statue of Liberty being underwater? Even with an ice free arctic this wouldn't happen.

The Statue of Liberty thing I actually don't remember the source of. I remember it as a clip in a climate documentary where the statue of liberty is visualized as being about a quarter submerged (note I said "semi-submerged", not "underwater", funny how the broken telephone works even when you can presumably see everything on screen at once).

I trust Snopes here since they are desperately attempting to cast Gore's statements in a positive light. They choose to address whether Gore "predicted" this event, rather than whether he disseminated the prediction. If the question is whether he confidently disseminated this prediction, the answer is a resounding yes.
The IPCC publish estimates generally between 2035 (on the very low end) and 2100+ (generally "possibly before the end of the 21st century", i.e. possibly later) for the arctic ice cap to melt almost completely.
