As others have noted, it can be really difficult to isolate sea level going up or down from local land going up or down.
Put water in a bowl it'll find it's own level... No parts will be higher of lower over time. (Yes, if you shake the glass - water will be higher on one side than another for a time - same as a hurricane pushing water ahead of it - and pulling it down from the back... ) But when you put the glass down the water again finds it's own level. My instinct is that 'sea levels rising' is one more 'the world is ending' liberal elite scam - like 'peak oil', global cooling, population bomb, Club of Rome, Alar, nuclear winter, etc. etc. etc. But I could be wrong.
