As I recall parts of the North American continent have been 'rebounding' since the retreat of glaciers from the last ice age. As sea levels rise can we expect the ocean floor to sink due to the additional pressure caused by so much more water over it? If so would the sinking ocean floor in any meaningful way mitigate the risks due to rising sea levels? If the sea floor sinks would that result in any kind of corresponding lift of land not covered by ocean?
