British Isles relative sea-level map

This is slightly off-topic, but worth sharing.  A beautiful map from Prof Ian Shennan and colleagues (Ian was in the Durham Univ Geography Dept when I was there, and he is still there).

The map shows current relative sea-level changes in the British Isles -- the result of a vast data collection exercise.  Note that in the north the land is rising slowly relative to the sea, and in the south it is sinking.  There are three basic factors:  glacio-isostatic adjustments still going on following the melting of the last ice sheet; crustal deformation as a result of tectonic forces; and the eustatic sea-level rise connected to global warming.

Main message:  if you live in the south of Ireland or the UK, you have a vested interest in stopping the rise of global temperatures.  Secondary message: if you are thinking about investing in some coastal real estate in the Isles of Scilly, think again.


PS. Sorry  -- should have given more details:

The units on the map are mm per year.  Minus symbol used for "sinking" areas.
