D. Just as when you add water to a bathtub the water rises everywhere, not just under the faucet. All coastal areas under 200 feet of elevation would flood.
If all the ice sheet of the Antarctic melted the sea level would rise by 200 feet- this has been calculated by many scientists.
Then I think most of this world will be under the sea & climate will get very cold.
I think my country would be submerged - we are pretty close to antarctica.
The climate keeps getting worse and people die, simple as that.
the sea level will rise
