It is generally accepted that sea levels increased during the 20thC at a rate of about 185mm or about 7”. Furthermore studies suggest that there was no acceleration in this rate during that time. One of the best known studies was by Bruce Douglas, who produced the above graph from Tide Gauge records for 23 geologically stable sites.
Satellite monitoring of sea level, which began in 1993, however, shows that the current rate of increase is about 2.8mm/year.
