美国东海岸上升如果每个人都住在那里搬走了吗?

我看了记录片研究格陵兰岛海岸海平面的 下降。根据这项研究,这是因为大量的冰川融化,导致更少的重量在陆地上和下的岩浆向上推动格陵兰岛。 我想知道是否美国东海岸也会上升,如果住在那里的人都是离开足够远的体重减少。因为有1亿人住在那里,我可以想象这是一个很大的重量。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?

人体的质量在美国东海岸东部沿海各州(约1.2亿)格陵兰冰质量损失,相比非常小,(根据Grace卫星数据)自2002年以来平均每年2730亿吨——5万亿吨在过去20年,即关于1/40,000th基于慷慨的体重为100公斤(接近80公斤)如果我的算法是正确的。(我必须编辑因为我算术 不是第一次)。 我不知道这将使一个的不同的重力影响陆地海平面附近——这取决于准确的测量,但它不会 。 建筑的质量,汽车卡车,机械将会超过,但是很多,质量将砾石和砂等材料制成的,在当地开采。再一次,这不会是重要的。 < a href = " https://i.stack.imgur.com/pwc3y.png " rel = " noreferrer " > < img src = " https://i.stack.imgur.com/pwc3y.png " alt = "格陵兰冰质量损失" / > < / >

,而人口的重量可能没有多大影响,阻止地下水的删除可能有相当大的影响相对海平面的高度。Lots of places are subject to "land subsidence", which is the vertical sinking of land due to groundwater removal and subsequent settling. The most notable example I have heard about recently is Jakarta, but other arid places also suffer from it. The east coast doesn't count as arid, but the USGS claims that 45 US states suffer from it, so it stands to reason that some of those are on the East coast
