I read your post and it occurred to me that you have consistently deferred to subject matter experts on the issues we have discussed on these threads. Perhaps that is why the two sides are always talking past each other.

I disagree with your statement "I'm not a scientist and I can't speak to glacial isostatic adjustment"--sure you can. Once defined, this is an intuitively obvious concept. If you, as an interested non-scientist, made some observation or argument that invalidated GIA, that would be just as pertinent to the discussion as anything said by NOAA, the SLRG, or anyone else.

GIA seems like a perfectly reasonable concept to bring to a discussion of sea level measurements and predictions. Not really that different from economists talking about 1990 dollars. It is, however, important for the scientists to explain that they are talking about sea level rise relative to 1990 ocean volume (or whatever the standard might be).
