Good lord. Do you think just making things up is science? An extremely brief summary, totally at odds with your bizarre "percentage" argument:

The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in the atmosphere warm a planet's lower atmosphere and surface. It was discovered by Joseph Fourier in 1824 and was first investigated quantitatively by Svante Arrhenius in 1896.[19] Existence of the greenhouse effect as such is not disputed, even by those who do not agree that the recent temperature increase is attributable to human activity. The question is instead how the strength of the greenhouse effect changes when human activity increases the concentrations of greenhouse gases in the atmosphere.

Naturally occurring greenhouse gases have a mean warming effect of about 33 °C (59 °F).[20][C] The major greenhouse gases are water vapor, which causes about 36–70 percent of the greenhouse effect; carbon dioxide (CO2), which causes 9–26 percent; methane (CH4), which causes 4–9 percent[not in citation given]; and ozone (O3), which causes 3–7 percent.[21][22] Clouds also affect the radiation balance, but they are composed of liquid water or ice and so are considered separately from water vapor and other gases. en.wikipedia.org

Yeah, it's wikipedia, the citation they give is ipcc-wg1.ucar.edu . That one goes into a little more detail but is still pretty straightforward in the introductory section. I don't think even the hardest of hard core skeptics deny the existence of the greenhouse effect as outlined above, e.g. that the earth is about 33 degrees C warmer because of greenhouse gases in the atmosphere.
