Abstract: The purpose of the work is to assess the reliability of satellite altimeter global mean sea level information through consistency, with other products such as ocean temperatures from thermometers or relative mean sea level records from tidal gauges, and stability of the proposed time series. The satellite altimeter global mean sea level is a mostly computational product. The result is unstable, as characterised by significant changes for the past results introduced in subsequent reconstructions. The result is conflicting with the measurements of ocean temperature, which indicates a smaller thermal expansion contribution. The result also is conflicting with the tide gauge records indicating local sea level stability.

Keywords: global warming; ice on land; ocean temperature; satellite altimetry; sea-level rise; tide gauges.
