claim: Global sea level data shows that sea level rise has been increasing since 1880 while future sea level rise predictions are based on physics, not statistics.
evidence: This network was used, in combination with satellite altimeter data, to establish that global mean sea-level rose 19.5 cm ( 7.7 in ) between 1870 and 2004 at an average rate of about 1.44 mm / yr ( 1.7 mm / yr during the 20th century ).
