When determining the rate of global sea level rise, the best method is to conduct a tide gauge station data analysis - latest analysis reveals claims of "accelerating" sea level rise to be totally bogus

Read here. Multiple "scientific" personalities seeking fame, fortune and influence (such as the likes of Hansen, Cullen and Rahmstorf) have attempted to frighten the public and policymakers by stating that global warming was causing an acceleration of global sea level rise. Depending on the given personality, they predict that recent "acceleration" will cause sea levels to increase anywhere from 4 feet to 75 feet by 2100.
Empirically speaking, these "predictions" are utter nonsense with literally no facutal basis - and, btw, that's why exceptionally lazy and/or amazingly stupid NY Times and Washington Post "journalists" just love these hysterical claims.
Per the actual tide gauge data plots shown above though, it is more than obvious that the readers of the mainstream press have been significantly mislead by the catastrophic global warming hucksters. The chart on the left represents annual sea level change since 1900. The red line is the 10-year average.
One does not have to be a climate scientist to realize that this chart unequivocally reveals a pattern of constant annual variation in sea levels with absolutely zero acceleration.
The plot on the right, examines the 10-year average in even more more detail. Since 1900, the trend of the 10-yr average actually shows a deceleration, not an acceleration of sea level rise. Using the 10-yr average at the end of 2011 as the sea rise gospel, by year 2100, sea levels would only increase by some 7 inches - not exactly the millions of "climate refugees" type of catastrophe (another spectacularly wrong AGW huckster prediction) that the MSM has been caught parroting without due diligence.
