The physical properties of water do indeed make it a more powerful greenhouse gas, and your article does not dispute that. Yes, as temperature rises, more water vapor will be in the atmosphere. Unless one can attach causation of a rise in temperature to CO2 in the atmosphere, water still remains a more powerful greenhouse gas than CO2, both directly and indirectly. Physical properties don't lie.Then you should be VERY upset about water vapor and NF3, which are both FAR more powerful and efficacious greenhouse gases than the one vital to all life on the planet, CO2.
But, since neither of them is a product of evil capitalistic man's evil combustion fetish, they're either not ever mentioned or they are minimized.
Every religion needs a devil, and CO2 is the AGW devil. Evil industrial capitalistic man are the demons.
You "believe" releasing greenhouse gases into the atmosphere is "bad" due to conditioning and mostly emotionalism.
Uhh...
Although CO2 makes up only 0.04 percent of the atmosphere, that small number says nothing about its significance in climate dynamics. Even at that low concentration, CO2 absorbs infrared radiation and acts as a greenhouse gas, as physicist John Tyndall demonstrated in 1859. The chemist Svante Arrhenius went further in 1896 by estimating the impact of CO2 on the climate; after painstaking hand calculations he concluded that doubling its concentration might cause almost 6 degrees Celsius of warmingan answer not much out of line with recent, far more rigorous computations.
Contrary to the contrarians, human activity is by far the largest contributor to the observed increase in atmospheric CO2. According to the U.S. Geological Survey, anthropogenic CO2 amounts to about 30 billion tons annuallymore than 130 times as much as volcanoes produce. True, 95 percent of the releases of CO2 to the atmosphere are natural, but natural processes such as plant growth and absorption into the oceans pull the gas back out of the atmosphere and almost precisely offset them, leaving the human additions as a net surplus. Moreover, several sets of experimental measurements, including analyses of the shifting ratio of carbon isotopes in the air, further confirm that fossil-fuel burning and deforestation are the primary reasons that CO2 levels have risen 35 percent since 1832, from 284 parts per million (ppm) to 388 ppma remarkable jump to the highest levels seen in millions of years.
Contrarians frequently object that water vapor, not CO2, is the most abundant and powerful greenhouse gas; they insist that climate scientists routinely leave it out of their models. The latter is simply untrue: from Arrhenius on, climatologists have incorporated water vapor into their models. In fact, water vapor is why rising CO2 has such a big effect on climate. CO2 absorbs some wavelengths of infrared that water does not so it independently adds heat to the atmosphere. As the temperature rises, more water vapor enters the atmosphere and multiplies CO2's greenhouse effect; the IPCC notes that water vapor (pdf) may approximately double the increase in the greenhouse effect due to the added CO2 alone.

What it does dispute is that your claim that CO2 doesn't really have much of an impact.
