Erosion
Sea Level Rise
The rate of sea level rise around the world accelerated throughout the
20th century. Over that 100-year period, eustatic (i.e., true) sea
level rise (ESLR) was 15 to 20 cm.
Recent observations have revealed an ESLR rate of 1.8 mm/year for the
period 1961 through 1993, and a rate of 3.1 mm/year for the period 1993
through 2003. These rates are compared to the background rate of 1
to 2 mm/year for the previous 19th century and the early portion of the
20th century.
A number of recent studies suggest that ESLR will likely be a meter or
more over the 21st century. These conclusions are based on
temperature-sea level rise relationships in the 20th century and better
understanding of ice sheet dynamics in what some content to be a warming
world.
