I watched a documentary about research on the coasts of Greenland where the sea level has fallen. According to the research, this is because a lot of the glaciers have melted, resulting in less weight on the land and a upward push by the magma under Greenland.
I'm wondering whether the US East Coast could also rise if all the people living there were to move away far enough for the weight to decrease. Since there are some 100 million people living there, I would imagine that's a lot of weight. However, I am thinking that since the inland US is part of a large continent, the magma would not be able to push it up like a "small" island like Greenland.
Do we currently have sufficient metrics to calculate such movements with fairly good accuracy?
