Geology is usually so intuitive, it's rare to find something that goes against your instincts. But isostatic rebound creates a moment of exactly that: the more landlocked glaciers melt, the lower the local sea levels drop. Here's how.
Our dynamic planet has an apparent paradox: the more ice melts from landlocked glaciers, the lower the sea level gets in nearby areas. How does this happen? Through the physics of isostatic rebound, when the surface of the planet acts as an elastic sheet dimpling and rebounding under changing loads.
