No, there does not, I'm afraid. Fred Singer shows one, but the IPCC never has.
This is because the coverage of the ocean by the tide gauges is so poor that
we judge that we cannot get anything more from them than an estimate of the
20th century average rate (1.0-2.0 mm/yr in the TAR), not a timeseries.
Sorry about that. Phil Woodworth is the expert on tide gauge records, which
can be obtained from Proudman Lab. For long records one does need to correct
for local land movements, of course.
Best wishes
Jonathan
