My original post: The strange thing is that all the weight of the ice is pulling our area down. When all that ice melts our area will be lifted up. So we won't notice much difference.
Edit: some facts are that the sea level at the west coast of north America has dropped and the sea level above Australia has risen. Sea levels are not as 'level' as you might think.
By the way: I'm not saying we should not worry and nothing is going on.
After looking more into it I must say the above is not true. Our area is just outside the 'dent' of weight of the ice. So our area is likely to go down a little when the ice melts.
It has more to do with the gravitational force of the ice mass. In our area the ice is pulling the sea towards it so the sea levels are higher. When this mass melts the sea levels in our area will go down.
- Grangar 7y agoThis is the first time I hear about this. Do you have a source for it?

- rb808 7y agoThere is a big gravity effect with ice sheets attracting water. If/when Greenland melts, water levels nearby will drop a lot, NW Europe might even fall too. https://sealevel.nasa.gov/understanding-sea-level/regional-sea-level/ice-mass-loss https://sealevel.nasa.gov/understanding-sea-level/regional-s...
- bcraven 7y agoEustatic change is much faster than isostatic change though. In a few thousand years you might be alright but you'd have been wet for millennia.
- mnsc 7y agoYeah, but that is one glorious millennia of getting to ignore climate change and keep burning dinosaurs like it's no tomorrow! Wroom!
- tsimionescu 7y agoI think that's the other way around - you get to drown now, but boy oh boy, you'll sure have a happy time come next millennium!
- perfunctory 7y ago> In our area the ice is pulling the sea towards it so the sea levels are higher. When this mass melts the sea levels in our area will go down. Isn't it the other way around? "The Antarctic ice sheet is also so large that it exerts a gravitational pull on the oceans: As it shrinks, sea water will redistribute away from the South Pole, causing an additional rise."
