Water vapor's effects

Global warming is apparently a fact. Yet it appears to me this warming is more closely related to natural climatic cycles. There are a number of websites that suggest that water vapor contributes as much as 95% of the greenhouse gases. The concentration of carbon dioxide is said to be about 0.04% versus 2-3 % for water vapor.

It is confusing to me that the effects of water vapor never seemed to enter the "warming equation" in the press.
