You are missing the point Lazs and so is Jackal.
Just the Icelandic glaciers would give you a bigger rise in SL than all the last century together.
Greenland would be some 20 feet.
You'd have 20 feet way before Greenland was gone though, for proportionally you'd be at 20 feet with 1/10th of the Greenland gone, with a mere 10% melting in Antarctica, - or so.
Add them up and you have some 200 feet.
You'd not fancy a trip to many an area after just a couple of feet, say alone 20, except for scuba diving down to remains of human habitat, - this is not new......
Ang Jackal's fridge has to be quite big to counter this.
Bottom line, Greenland's Glacier is still in place, but it's shrinking at a scary speed, - speed increasing.
Like riding in 60 mph then 70, then 80, and noticing you went from 60 to 70 in 200 secs, 70 to 80 in a 100, and 80 to 90 in 30, - where does that point you?
