We’ve been waiting for the UC web page to be updated with the most recent sea level data. It finally has been updated for 2008. It looks like the steady upward trend of sea level as measured by satellite has stumbled since 2005. The 60 day line in blue tells the story.

From the University of Colorado web page:
Since August 1992 the satellite altimeters have been measuring sea level on a global basis with unprecedented accuracy. The TOPEX/POSEIDON (T/P) satellite mission provided observations of sea level change from 1992 until 2005. Jason-1, launched in late 2001 as the successor to T/P, continues this record by providing an estimate of global mean sea level every 10 days with an uncertainty of 3-4 mm.
They also say:
Long-term mean sea level change is a variable of considerable interest in the studies of global climate change. The measurement of long-term changes in global mean sea level can provide an important corroboration of predictions by climate models of global warming. Long term sea level variations are primarily determined with two different methods.
Yes, I would agree, it is indeed a variable of considerable interest. The question now is, how is it linked to global climate change (aka global warming) if CO2 continues to increase, and sea level does not?
There’s an interesting event in October 2005 that I’ll come back to in a couple of days.
