Is it because water vapour cannot be taxed?
Because it would expose these saviors of the earth as con artists. You can't tax water vapor. The world isn't that stupid, but the saviors of the earth are working on it. They have got our educational system in their pocket.
Water vapor is counted, and in your particular reference it is counted wrongly. You'll notice that in their Table 3, which they give no reference for, they have a value of 95.000% for water vapor. That should be a tip-off that something is wrong--do you think they really know that value to 5 significant digits? No, they don't, they just picked the 95% number out of the air without any theoretical support for it, then combined it with the other numbers. I believe Richard Lindzen gave a number like 95% many years ago, but has since backed off from it. For more accurate numbers see the paper by Schmidt et al "Attribution of the Present Day Greenhouse Effect." You can see an AGU press release about the paper here http://www.agu.org/news/press/pr_archive... . The greenhouse contribution of water vapor is closer to 50% than it is to the 95% used in your link.
The amount of water vapor in the atmosphere is controlled by many things: the distribution of water on the planet, the winds, but most importantly the atmospheric temperature. That's because the saturation vapor pressure is a nonlinear function of temperature, through the Clausius-Clapeyron Equation. With each degree Celsius of warming, the saturation vapor pressure goes about 6%. Since water vapor IS the most important greenhouse gas, that means that if an increase of any other greenhouse gas that causes warming will be amplified by a concomitant increase in water vapor.
In the natrual Greenhouse effect, water vapor makes up for about 60% of it. But in the manmade Green house, water vapor only makes up 0.1%.
Water vapor is the greatest volume of the greenhouse gases but is natural not manmade
False premise, it is counted in the total.
And if you think you found something new, "Water vapor is the most powerful greenhouse gas" is denier myth number 35 on Skepticalscience dot com, a useful site that keeps a list of the more common denier claims and debunks each and every one of them.
Edit:
And my point is that water vapor is counted in the total, therefor your question is based on a falsehood.
It is counted, their theory is that Co2 will not make much of a heat rise but will change the amount of water vapor that will cause significant temperature rise, but it doesn't seem to be working out that way. plus the media don't talk about it because it makes CO2 look as insignificant.
Curious, where is it not counted?
The IPCC has an entire section of it in their 2007 report.

Maybe you are mistaken.
It usually isn't harmful genius...
Pretty much.
because its uncountable..just we can make guess
Greenhouse gases, why is water vapour not counted in the total?
