No it doesn't, as has already been pointed out. And all the icebergs in the world melting won't change the ocean temperature enough to alter sea level. If anything the cause/effect is the other way around. If ocean water is warmed due to climate change, this could contribute to icebergs melting. The bulk of an iceberg's mass is already under water.
This is a little off from the original point that started this tangent, which is that some posters thought that melting icebergs raise sea level. It's been calculated (in a study someone linked earlier) that just due to the salinity difference, if all the icebergs in the world melted forever it might raise sea level 2 inches (once and done). But not because of more water, since icebergs are already in the water. Also, if we reach the point where all icebergs in the world melt, sea level won't matter anymore. We'll already be extinct or living on Mars.
