The Earth’s oceans are rising. It’s an inevitable outcome when
ice sitting on land melts and when oceans warm, which causes their
volume to expand. But if you live at the coast, it may not be
rising near you. Places like Miami and Newport News are
experiencing floods at many high tides. Some places in Alaska, in
contrast, are seeing the oceans edging away, as land seems to lift
out of the sea (albeit incredibly gradually).

How can that happen?

It happens because the Earth’s not a bathtub—adding more water
doesn’t increase ocean levels evenly. As this video details, there
are lots of factors that add a local twist to the overall rise of
the oceans. These factors range from the strength of ocean currents
to the gravitational pull of large ice fields. The net result is
that the US has some areas where ocean levels are actually falling
a bit and many others where they’re rising even faster than the
global average.
