Last I check, we're on these floating masses called "plates" and they actually move around, shift and stuff. Some get pushed under others, etc. Wouldn't that simply explain why one section might be seeing a change in sea level and not another?
Lastly, why does everyone panic when the world changes a little? We have fish fossils on mountain tops, dinosaur bones, the land mass used to be one large hunk of land. Mountains were created through plate shifts and valleys and hills formed by ice ages. So, knowing all this... Where do we come off panicking when there is the slightest change from the prior year? Do folks expect the world to sit stagnant as we know if forever and ever, and all the history of the world be damned? It will never change again?
Seems like these things are more politically motivated and looking for someone to blame rather than someone rationally just standing up and saying "Well, what did you think was going to happen? The same thing year after year? Had to change sometime..."
