Some like to blame rising sea levels on global warming. The fact is, there are at least 6 reasons the sea is rising that have nothing to do with global warming. Consider there are roughly 3 tons of dust that comes to this planet from space daily. That is over 1000 tons a year. If it is evenly distributed, that is almost 800 tons that goes into the oceans yearly. You add to that the tons of silt that the river wash down from the land, that is a lot. Every particle displaces just a little water.

Considering the size of the oceans, that is not much, but I would suspect it is more than caused by global warming.
