Okjökull is considered extinct, yet according to this website it should survive until the 2070s at least? It also gives 2079 for 1.5°C vs. 2075 for 2.7°C (I know that the local dynamic is not the same as the global one, but still).
The data is somewhat outdated:
Extinction is defined relative to the initial glacier outlines from the Randolph Glacier Inventory (RGI v6.0): released July 28, 2017.
