Models find large natural variability in future regional sea level rise



Melting glaciers, ice caps, and ice sheets and thermal expansion of seawater, along with groundwater depletion, have already caused the global ocean to rise at a rate of 1.8 centimeters per decade over the past century. In recent decades the pace has climbed to 3.1 centimeters per decade. As the atmospheric greenhouse gas concentration continues to rise, so will the oceans.
