Assuming that All Ice on Earth, Natural AND Artificial, were to Suddenly Melt, How Much of a Rise in Sea Level Would That Be? - 2021

Climate Change, Anthropocene, & Associated Issues

Eux reported by modeling that:

Greenland adds about 8 meters of sea elevation (26 feet rise)

Antarctica adds a whopping 65 meters of sea elevation (210 feet rise)

All the other glaciers add a final 1 meters of sea elevation (3 feet rise)

So all in all, about 74 meters of sea elevation (240 feet rise)

The last time the seas rose like that because lots of ice melted, they rose about 120 meters of sea elevation (400 feet rise). But on average they melted at 15 mm per year (currently the seas are rising at 3.6 mm per year, on average around the world)

Here's what a rise of 60 meters of sea elevation (200 feet rise) looks like in the Mississippi Valley, Scotland, eastern Java & Bali, Bangladesh & Florida
