Dietmar Müller, a geologist at the University of Sydney in Australia, says understanding the natural causes driving sea level change will help scientists evaluate to what extent human-induced global warming is now affecting ocean levels.
In the late Cretaceous era, about 80 million years ago, global levels were 560 feet (170 meters) higher than today, according to a reconstruction of ocean basins from the time.
