You should be more respectful of complex things. You think about things in a very simple-minded manner. Simplistic thinking is misleading. You're convinced the only thing that affects the climate is manmade CO2. Nothing else (volcanos, sunspot activity, changes in solar radiation, plankton in the ocean, deforestation, reforestation, and a million other things) matters because you don't consider any of it. There's only humans and fossil fuels and CO2. 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.. The above is a thought experiment, not a real experiment. I'm sorry you don't understand the term. If you actually got a box - actually you'd need several - and some dry ice and a thermometer, you could perform a real experiment. I think you'd be surprised at the result. And you said you don't understand which side I'm arguing when I said this??? Because you said it in answer to my citing the fact that the last couple million years have been primarily ice ages with brief warm periods like the current one separating them: re:"Did you know that times as warm as we enjoy now have been very rare over the last couple million years? Over the long haul, warming will not be the climate danger we face." 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. Which side are you arguing?
