“This would then mean that we are reaching the penultimate phase, which is comparable to the 20 to 25 meters we saw during the last climatological optima in the middle Pliocene & in the middle Miocene, when temperatures in the Arctic Ocean & Southern Ocean were similar to today.”

“The final phase, which some think could not occur until after 2100, is that of an ice-free planet. Then we are talking about a SLR of 70-90 meters, due to the expansion of the oceans. I think this scenario is already baked into the climate system.”
