Why ocean levels may not rise so much

by Newnameelizabeth

During the q&a of this informative lecture

someone asked if melting glaciers would increase the weight of the ocean, causing it to subside and get deeper. The lecturer said that is logical, and not something he’s read, but that he thinks tectonic movement of the ocean plates changes the shape of the basins more dramatically.

Therefore, the oceans could create more room for melting glaciers. We don’t understand all the movements and changes of the earth to accurately predict such things. And we can’t say that the way lower levels of shorelines were due to glacier displacement either. They seem to be finding that tectonics are responsible for many features rather than uniformitarian water movement alone.
