This figure is a compilation of paleo sea level data (purple), tide gauge data (blue, red and green), altimeter data (light blue), and central estimates and likely ranges for projections of global-mean sea level rise from the combination of models for Representative Concentration Pathways for a scenario that corresponds to above 700 ppm C02-eq but below 1500 ppm) (blue) and a worst case scenario (red), all relative to pre-industrial values. These data confirm that the rate of rise has increased from low rates of change (on the order of tenths of mm/yr) to rates of almost 2 mm/yr averaged over the 20th century, with a likely continuing acceleration during the 20th century.
