Oh yeah, I am pretty sure there really is such a thing as climate change, but there isn't one dang thing that man can do to start it or stop it. Man does have the capability of messing up our atmosphere, but hardly as much as nature is capable of and often does a real nasty job of. When Mt. St. Helens blew it's top, it really sucked around here for several months. Everything was covered with the fallout from the mountain and it wanted to rain all of that summer of 1980. It turned out that Mother Nature knew exactly what she was doing. That rain washed all the volcanic ash off everything and most everything was back to normal in a relatively short time.
I think it is pretty well understood that we (the Earth) actually is in between a glacial period. I for one appreciate that enormously, because during an Ice Age, where I'm sitting right now would be covered under about a mile thick sheet of ice. There is a lot of conjecture about how and why glacial periods begin and end. The one thing for sure is that man hasn't got a thing to do with it.
As for the rising of the oceans, there really isn't anything man can do about that either. Nor should we waste our time trying to modify what nature will do when it will do it. The latest figure that I have heard and read about claims that the oceans have risen about one centimeter in the last 100 years. That should scare the crap out of weather freaks, but it doesn't bother me. First of all, the oceans are never, never, never static. There are the tides, storms and even Antarctic weather events that have influence over ocean levels.
One has to wonder where, when and how anyone would go about actually measuring ocean levels. Who and how was the ocean level measured a hundred years ago? How is it measured these days? How can an accurate measure be taken on something that is never static? Well supposedly there was a satellite stuck way out in space somewhere that is capable of measuring ocean levels on Earth. The cost for that was probably enough to buy everyone in the USA a new home on higher ground. Anyway, one centimeter isn't likely to be much of a problem for me. Right now I have more concerns about how long Mt. St. Helens is going to behave. You just never know about these Volcanoes.
