You don't know what you are talking about, no cites.


That is a cite. You did not read it. That is a
respected university that plots the standard sea level
data as it comes from the satellites. It also has links
to the tide gage data. Very informative. Totally scientific.

There are also geologic sea level records, they proof that in the
last 2000 years the sea level changed by about 10 cm/century up to
1850.


They can only tell us sea level at a limited number of places.
They are interesting science, but they do not provide mm of
accuracy for global sea level.

There is an uncertainty on the order of mm/year in our measured
data. One mm/year is 10 cm/century. So we have
different ways of measuring with different answers, but they
agree within the error of the measurements. The sea level
could rise by a foot in the next century. That is all the
measurements tell us. There is nothing in the satellite
or tide gage data to say that the current rise is more
than 10 cm/century.

None of the methods of measuring sea level show acceleration
alone. The illusion of acceleration comes from comparing different
data sets that have different long term drift. The sea level has
been rising since the end of the last glacial. No doubt
about it.

The IPCC report has a section on this.


The IPCC report is an insult. Give me something technical
on the order of the university of colorado web page or the
noaa data I have also mentioned here. To date there is no clear
acceleration in CO2 or sea level rise.

Show me data, or shut up.
