NOAA has a
sea level trends website where there is a really cool map and you can see how the sea levels have been trending, around the globe. (Since 1992, these levels are monitored by satellite.)
There is a marker right near where this Hebrides location is, and it reports:

The relative sea level trend is 2.28 mm/year with a 95% confidence interval of +/- 0.75 mm/year based on monthly mean sea level data from 1977 to 2016 which is equivalent to a change of 0.75 feet in 100 years.

The global warming worry, in sea level change, is that it will accelerate. So far, it hasn't done that, but the concern I believe is for Greenland and such.
An interesting note... on that map, there are a third of places around the globe where sea levels are falling. In northwestern Canada and Alaska, sea level is falling very fast. 5 feet per century, in some areas.
This is actually due to the land mass "rebounding" for the last 12,000 years, after the last ice age. It has lost the weight of all the ice that was on it, and on a geologic time frame, it still takes all this time for the land to spring back.
