I am not saying that water vapor is or is not a factor - but that the scientists state that it is of course the leading greenhouse gas in our atmosphere which is hardly ever discussed.
When water vapor gets angry, though, it is the major cause of much of our problems. Hurricanes. The energy in a hurricane is a localized vortex feedback loop within the molecules of air and water vapor entrapped. People hate hurricanes mainly because they want to live by the water - and when the weather is nice, not many places are better than a seaside location. In a way, isn't this a form of "real-estate greed" - where living in the nicest of spots should be protected in ways that include our own attempts to change the planet's climate cycles? It's a form of saving face because we (silly us) built big expensive cities on the waterlines in various spots like Beijing, NYC, London, Amsterdam, etc, and fixing those cities to support a large oceanic rise of up to 5-10' is a cost we may not be able to easily bear? Maybe we have to face that we were pretty ignorant of the long-scale of ice history until the past century's scientists discovered what they did in the antarctic ice. Sea levels were 20-40' lower a couple thousand years ago. But no records really exist. They haven't risen that much in the last 100 years, actually.
How much is sea level rising? The graph there shows that rise was happening in the early 1800s and the slop is not really as much of a ramp as you'd expect with the industrialization since 1900. But the slop is an increasing slope, and that is visible in that graph. It seems to be a gigantic gentle uptrend and that means it takes a gigantic amount of effort to reverse the trend. Rather than pushing an ocean-liner with a tug-boat, this is like trying to push the island of Kawaii with a a speed boat. I believe such large and long trends of such a graph shown in this sea level rise chart may be impossible to change by slightly altering our emissions alone. We have to look further into the earth's axis angle as it has wobbled over the last 24,000 years and some of that comes into play with the amount of sun hitting some parts of the globe over time.

Anyway - here's something to check out.

There are really multiple angles in this environment model and perhaps many of them are not conflicting but constructive of each other. But can our distributed humanity and various culture really come together to fix things or are we fighting a horrible uphill battle of hope?
There are a whole lot more things that can come into play longer term. One is the moon's location is continuously getting farther from the earth by just under one inche a year (I am taking a very long term view on that). This can lead to rotation and axis changes for the planet longer-term and less tidal pull as well. We want less tidal pull if the oceans are going to be rising slightly. Who's got all the answers? Nobody, really. I think science and its discoveries are just helping focus on the bigger macro picture of the inevitable long-wave changes on a dynamic planet. I think our biggest problem as humanity is everyone thinking they have all the answers and the infighting when each group want to be right.
