The University of Colorado shows sea level rising at a steady rate of 3.3 mm/year, which is a higher rate than 84% of tide gauges report
But they didn’t always show that. In 2004, they showed the rate of sea level rise as 2.8 mm/year
Overlaying the two graphs (of the same data sets) you can see that they don’t look anything like each other. In the old graph, there was a trough in 1997, and in the new graph there is a peak that year.
The next animation shows how their published data set has changed since 2004.
2015 : 2015_rel2/sl_ns_global.txt
The next graph shows the changes made to the data. They added an extra 10 mm of sea level rise from 1993 to 2004.
As with every other US government funded climate data set, the data is continuously being altered to create the case for imaginary global warming. The temperature is not increasing, so they have to keep faking the data to keep the scam alive.
