It's true that the effect adds to both high and low tides, however we are talking mm's here (at least at present) as opposed to meters for the tides themselves, and the variation in the tides with wind and weather is going to totally swamp the effect you are talking about. That's why I said it gets lost in the noise. Of course, over the longer term (a hundred years?) the effect you mention will play a role, however I suspect that even then it will not be all that significant. Furthermore, much of the covered land will be what is currently beach anyway (sand IOW), and sand is also quite reflective. I can't guess whether covering it with water would increase or decrease the total reflectivity. Regards, Robin van Spaandonk The shrub is a plant.
