The research, published Monday in the Proceedings of the National Academies of Sciences, shows that global sea levels have risen roughly three millimeters (0.1 inches) per year in the past. However, that rate is not constant—it may jump to 10 millimeters per year by 2100.
Significantly, the projected sea level rise is a "conservative" estimate and may likely be higher, the researchers warn.
"There may be abrupt changes in the ice sheets," lead author Steve Nerem, a University of Colorado-Boulder professor of aerospace engineering sciences, told ThinkProgress. “That's why I think that this is a conservative estimate, because it doesn't consider what if the ice sheets really start to go."
