By the way, you will note in my initial source that the final point in the dataset is level with the initial point (slightly below).  So it is, in fact, unchanged.  You can quibble about smoothing methods, how to fit a regression, etc., but that is the literal english definition of &#x27;unchanged&#x27;.<p>Is that defended enough for you?  Right now the sea level in the Marshall Islands is roughly where it was 23 years ago.  That would be UNCHANGED.
