How can the worldsworld's sea level rise and fall simultaneously?

I have just been reading this article on GizmondoGizmodo (known for its hard science I know), that talks about the sea level rising by up to 3 feet(!).

In the article and video, created from information from NASA it seems, it states that over the last 23 years that the sea level has risen in some areas and subsidedfallen in others.

Now, whilst I am aware that the level of water will vary with tides, how can the general sea level fall in some areas whilst it rises in others?

Surely if I add 9999 million gallons of water to the oceans, then the water level of the whole world should raise by the same amount everywhere?

How can the sea level rise in some places and fall in others?
