Figure 3: Global
mean sea level variations (light line) computed from the TOPEX / POSEIDON satellite altimeter data compared with the global averaged sea surface temperature variations (dark line) for 1993 to 1998.
However,
the mean sea level variations inferred from the remnants of the Roman era suggest that a similar high rate of increase may have occurred more than 2,000 years ago.
Not exact matches
As you are aware there are major local
variations from the global pattern, with coastal land in some regions sinking faster than the average and in other regions being uplifted with respect to
mean sea level.
The map of regional
mean sea level trends provides an overview of
variations in the rates of relative local
mean sea level observed at long - term tide stations (based on a minimum of 30 years of data in order to account for long - term
sea level variations and reduce errors in computing
sea level trends based on monthly
mean sea level).
The authors observe that wide
variations in rates of tectonic uplift and subsidence in different locations around the world at particular times
mean no effective coastal management plan can rest upon speculative computer projections regarding an idealised future global
sea level, such as those provided by the United Nations» Intergovernmental Panel on Climate Change (IPCC).

variations in global
mean steric
sea level computed by Willis 2008 (gray line) and Leuliette 2009 (black line).

mean sea level associated with the 1997 — 1998 ENSO event: Implications for measuring long term
sea level change
Table 1 summarizes
