Researchers report that sea-level rise since the industrial revolution has been fast by natural standards and -- at current rates -- may reach 80 centimeters above the modern level by 2100 and 2.5 meters by 2200. The team used geological evidence of the past few million years to derive a background pattern of natural sea-level rise. This was compared with historical tide-gauge and satellite observations of sea-level change for the 'global warming' period, since the industrial revolution....
