Our transcription: But there is also a long-term change going on all the while.
Since the peak of the last ice age, tens of thousands of years ago, melting glaciers have spilled immense quantities of water into the oceans causing a rise in sea level of over 100 meters.
Such a global change in the volume of water in the ocean is known as a "eustatic change."
Although today's sea level is much more stable than it was at the time the Ice Age ended, a small eustatic change is still going on.
The glaciers of Greenland and Antarctica are continuing to melt faster than they grow.
This causes a small, but steady, rise in sea level worldwide.
