"Water Vapor is the largest contributer to the greenhouse effect and there are other gases that contribute as well" That they do. But they aren't being generated by humans in nearly the same quantities. So unless natural processes are generating them, they will be relatively static in absolute terms. "As for your calculations. You have to consider that not all the carbon in coal goes to CO2 production." The most conservative approach is to assume CO2. Besides, CO is going to be pretty quickly oxidized. "I don't know about the figures for coal production." Shrug. Find others. "If your figures for total production are correct than most of it has to disolve in water, or get used up by plants, or become part of carbonates or be bound up or transformed by some other process." Apparently about half goes that way pretty quickly. So there are natural sinks. The problem is, especially as the rest of the world industrializes, the amount will only go up. Coal is readily available and doesn't need a lot of technology to use. But also, because apparently the atmospheric concentration takes a lot to push up, then a relatively modest effort should pay off. Carbon neutral technologies, conservation and other steps can have a big impact. We still might need to build Benford's Big Lense, but the problem is likely manageable. Sitting on our thumbs doesn't do it. Which is not to say that 280 ppm is desirable. It probably isn't. There are reasons to believe that we could be in a general cooling trend anyway. So some CO2 production is probably not a problem.
