Quizplus · Accepted Answer

Worldwide sea level was about 130 m (430 ft) lower 18,000 B.P. at the peak of the last glacial period when much of the Earth's water was frozen in glaciers. Since then, as glaciers have melted and ocean temperatures have risen, worldwide sea level has risen. In the past 100 years or so, it has risen about 10 cm (4 in) due to human-induced global warming.
