re:"carbon cycle, etc is incredibly complex though and thinking about it simplistically is a mistake. " When a scientist experiments he tries to separate the variables through controlled experiment. That's how the complex is studied to be understood. From my recent discussions with I've learned that you are very intimidated by what you consider complex. Thinking is never a mistake. re:"I don't recall you mentioning a simple thought experiment like that. Simple thought experiments aren't sufficient for complex things." re:"Remember I told you that CO2 is more thermal insulating than air. "No. I don't remember that. I would have asked you what "air" is to you" Let me refresh your memory....and this is not a thought experiment...its an experiment that can be done in a laboratory or your basement. From: Me to you.....#101872 A primary source of heat loss from the planet is through radiation. Hence, the thermal conductivity of the atmosphere largely controls the amount of radiation. All gases have different thermal conductivities just as all other materials do. For example, silver has the highest thermal conductivity of all metals. With respect to gases, CO2 has only about 64% of the thermal conductivity of air. It is easy to see therefore, that increasing the concentration of CO2 in the atmosphere will reduce the thermal conductivity of the atmosphere. If we ran an experiment with a box of air that is exposed to a sunlamp cycled to simulate an earth day and then measured the temperature as a function of CO2 concentration, what do you think would happen? Answer....the temperature would rise. 7.9 billion metric tons of CO2 were produced in 2005. About 500 billion metric tons have been produced by the industrial revolution over the last 150 years.. And you said you don't understand which side I'm arguing when I said this??? That's the very point.....the earth's warming is happening because the CO2 concentration has been increasing rapidly as we continue to increase the amount of fossil fuels we burn. What is it you don't understand about that statement?
