First off, anyone referring to Wikipedia as their primary source for anything cannot be taken seriously.
First off, re-read what I wrote. The wiki page is a list of authoritative sources. I did not say the wiki page itself was an authoritative source. If you bothered to visit the page you will see it is just an exhaustive list of sources, it is not an article, it is a list of links to the authoritative agencies and what they've said on the topic.
it can never be proven 100% right, or wrong.
That's correct. NO theory can ever be proven 100% right or wrong. In fact it's a virtual certainty that every theory, from relativeity to the standard model of particle physics to the theories around global warming to evolution--they are all wrong in some way.
In fact our theory of gravity is utterly incompatible with our theory of particle physics. One of them MUST be wrong. On this basis you can argue, accurately, that gravity is just a theory and not proven. Nevertheless when you drop a hammer on your toe you will find out that this wrong theory of gravity anyway makes reasonably good predictions.
The same is true of theories about climate change. They turn out to have useful predictive power--the ones that posit a human cause of climate change anyway. They turn out to have accurately predicted data that wasn't know when the theory was generated. The alternative theories turned out to predict wrong values for that data. Just like the hammer falling on your toe the theories which to date have had the best predictive power predict that the pollution we are generating is warming the planet.
I agree with most scientists that even if this is happening, the greenhouse gases are not present in nearly enough quantity to see significant changes in global temperatures.
See the list of citations on the Wiki link to see how many scientists agree with you. It's an exhaustive list of the peer reviewed journal articles and statements from other peer reviewed circles on the topic.
The reality is that most scientists do not agree with you.
Another reality is that from your description of science I can tell that if you actually are a scientist it is not in any of these areas, because you talk of controlled experiments as though they were the only way to provide evidence for a theory.
In fields like climate research the gold standard is whether or not your theory correctly predicts the values that will be found for data that is as yet unmeasured or even unmeasurable. When that data is finally discovered those theories that predicted it properly are strengthened, and those that predicted radically different values are invalidated by the findings.
It was through this process that the theories that global warming had non-human causes were invalidated: they predicted values that turned out to be false. The theories that global warming had at least partial human causes predicted values which, when finally measured, confirmed the predictive power of the theory.
putting water vapour into the atmosphere
Your error is in the phrase "the atmosphere", what exactly do you mean by that? Gasses at ground level are irrelevant.
Perhaps you should leave this to scientists who actually study this field rather than speculating on your own, you obviously lack the required expertise. In that respect you, and any policy maker who lacks the required expertise (which is pretty much all of them) should instead rely on the current best information available from the community of scientists who are experts in this area.
You will find links to those consensus findings on the wiki page above. Note again, I am not citing the wiki page as a source, I am pointing out that it has an excellent list of citations, and I urge you to follow up on them.
