In 1982, NASA showed just over three inches (8 cm) of sea level rise from 1880 to 1980. They also showed a sharp slowdown in sea level rise rates after 1950.
Three inches isn’t very scary, so the EPA has doubled that figure, and shows six inches of sea level rise from 1880 to 1980 – with completely fake acceleration after 1950.

This graph overlays the two graphs at the same scale. The EPA data is political, not scientific.
Tide gauges show a slowdown in sea level rise rates, so government propaganda agencies tamper with them and now simply ignore them, instead using incredibly poor interpretations of satellite data since 1993. But even this data is being tampered with over time.
In 2004, the University of Colorado (who got beaten up by Oregon yet again last night) showed sea level rise rate of 2.8 mm/year, with an error of +/- 0.4.
That wasn’t very scary, so they have since changed the data and moved it outside of their own error bars to 3.3 mm/year, using a Global Isostatic Adjustment which is 100% fraudulent in the context of sea surface height. That adjustment was intended to calculate ocean depth as the sea floor sinks, but has no bearing on the accuracy of measurement of sea level by satellites.

The image below overlays them at the same scale. The University of Colorado simply altered the data to make it look a little scarier.
But here is the real smoking gun of fraud from the IPCC.
In 1990 the IPCC said :
there is no convincing evidence of an acceleration in global sea level rise during the twentieth century
there is weak evidence for an acceleration over the last 2-3 centuries
In the 2013 report, they say the exact opposite
The 2013 IPCC report (AR5) concluded, “there is high confidence that the rate of sea level rise has increased during the last two centuries, and it is likely that GMSL (Global Mean Sea Level) has accelerated since the early 1900’s

Very little of what you hear about the climate from government or academia has any validity. They are simply fabricating data for political and monetary purposes. It is a $29 billion dollar per year RICO style racket, and the biggest scam in history.
