Global Sea Level Rise

Global average sea level since 1880 (compared to 1995).  Data composited from CSIRO (1880-2013) and satellite observations (1993-present).

Even though the rate changes, sea level is clearly rising.  It’s already about a foot higher than in 1880, and is expected to rise by up to a meter by the end of the century (if melting of polar ice sheets accelerates, this number could be much higher).  This figure was inspired by Dr. Ed Hawkins’ now-famous climate spiral, and took advice from this talk on making beautiful figures.
