My point is that if the carbon dioxide theory were correct, we would all be dead. Water vapor does a better job than Carbon Dioxide at absorbing and re-radiating solar energy, and so if that were the only effect in play, those billions of tons of water vapor floating around should have turned the planet into an 800 degree hellhole like Venus.
That's if the C02 theory is correct. Obviously there is a mechanism in place that prevents a runaway greenhouse effect, and that mechanism is the increased reflection of energy at higher altitudes by that very same water vapor.
Water vapor goes from being a positive feedback device (above 32 F) to become a negative feedback device at higher temperatures.
Whatever the capacity of C02 to heat the atmosphere, water vapor is more than capable of countering it by increased reflection of solar radiation. Water vapor drives the system, and the influence of C02 is too trivial to have much of an impact.
The greenhouse effect of CO2 is far surpassed by the greenhouse effect of Water Vapor, and the cooling capacity of Water Vapor reflectivity far surpasses the heating ability of CO2.
