Just checked the Glacier Blanc in the Massif des Écrins. The map's glacier vector perimeter is completely wrong : the glacier has retreated hundreds of meters already.

I hope this is just a map thing, and not the base for these predictions :/

We chose this and we're still choosing it right now.

I don't understand why a glacier would survive longer in the 4°C scenario than 2.5°C but this seems to suggest so.

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).
