From 1961 to 2003, the average rate of sea level rise was 1.8 ± 0.5 mm per year. (Sea level change is highly non-uniform spatially, and in some regions, rates are up to several times the global mean rise, while in other regions sea level is falling.)
But the rate of sea level rise may be increasing. For the period 1993 to 2003, the rate of sea level rise is estimated from observations with satellite altimetry as 3.1 ± 0.7 mm per year, significantly higher than the average rate. The tide gauge record indicates that similar large rates have occurred in previous 10-year periods since 1950. It is unknown whether the higher rate in 1993 to 2003 is due to decadal variability or an increase in the longer-term trend.

Since the end of the last ice age 10,000 years ago, the sea has risen about 50 feet. Before the last ice age began and trapped all the water in the ice caps, the sea level was about 30 feet higher than it is now. It is part of a natural cycle that we have absolutely no control over. Stupid tree hugging liberals want to spend tax dollars on their pet projects so they can feel good about themselves. Dumb @ss right wing neo-cons want us to continue breeding ourselves into oblivion. Mean while my friends and I will be hold up in our mountain hide a ways more than willing to blow away any unprepared liberal/conservative moron that thinks they can take our well stocked supplies away from us for the common good. They flushed the common good down the crapper long ago and we really don't care if they starve to death.

That's two questions.
The sea level has definitely risen. That's not debatable, that's obvious.
The "debate" , is why has it risen. So the fact that global warming advocates have predicted such things is kind of immaterial to those who want to "debate" the issue.

The sea levels have actually gone down in the last 160 years.
