The linked article gives an insight into the accuracy of the state of the art satellite sea-level measurements. You will see that they are not as accurate as you might think as you read through to the end. Here is the link:
The very last points are set out below and need to be emphasized.
5. The ONLY sea level, or its rise or fall, of any importance to any locality or its governmental bodies is Local Relative Sea Level. This sea level rise (or fall) caused by rising absolute sea level rise combined with vertical land movement (in most instances, downward) determines the magnitude of any risk or threat from sea level rise for that location.
6. Many localities which have valuable infrastructure built on land only a few inches or feet above existing mean sea level for their location are already at risk of flooding by spring tides and storm surge and need to initiate changes in building codes and begin mitigation immediately. The sea will continue to rise, ever so slowly.
So far there is no evidence of any change in the long term gradual rise in sea level here in the UK which is set at around 7 or 8 inches per century (16 to 19 cms)
