Now if I stop some of the heat leaking out by wrapping my oven in a thermal insulator, the temperature must rise until the heat going in matches the heat leaking out again*.

It happens slowly enough for the whole system to be largely in thermal equilibrium. No one is disagreeing with this description of the physics. You have been unable to provide an estimate on the actual effect one might expect from this feedback loop. I think I've made my point that arguing AGW based upon a 3 degree rise in atmospheric temperature is hogwash. So, you're arguing that a feedback loop has been going on, and we are enhancing that feedback loop by putting CO2 into the atmosphere. Somewhere in that feedback mechanism, there is an open thermodynamic system. It's not closed. Q accumulated = Q input - Q output. The earth, sea, and air all have their own control volumes around which to do this dynamic balance. Each of the Q input/output variables will have multiple driving forces. The dominant forces here will be evaporation, convection, and radiation. Since we are basically at equilibrium, Q accumulated is zero. Therefore, Q input = Q output. Again, you have not been able to explain why CO2 in practice will have a significant impact. I fully understand its insulating properties, but as far as I can see, it seems to be insignificant. Since this seems to be high school to you, why don't you whip up some calculations, and share the numbers with us.We are all engines of karma Quote Share this post Link to post Share on other sites lawrocket 3 #366 July 15, 2009 QuoteHow can you be both selfish and selfless at the same time?

Methane is less important in AGW because: -there is much less of it in the atmosphere (1.7ppm vs 380ppm for CO2) -its half life is much shorter in the atmosphere (7 years vs 30 years for CO2) -we have reduced our increase in methane emissions (went from .7 to 1.7ppm but has leveled off)* -its total contribution to AGW forcing is much less (.4w/sq m vs 1.4w/sq m) (* - unfortunately it has started rising again in the past few years; let's hope this is just a blip) Quote Share this post Link to post Share on other sites chasteh 0 #372 July 15, 2009 >You cannot Bingo.

If you mean "how well does it conduct heat from the surface to space?" the answer is "it doesn't." The earth is in a vacuum, and cannot conduct heat anywhere. >How well does it radiate heat? Pretty well. CO2 (and the rest of the atmosphere) do most of the "radiating away" of our heat.

It happens slowly enough for the whole system to be largely in thermal equilibrium. No one is disagreeing with this description of the physics. You have been unable to provide an estimate on the actual effect one might expect from this feedback loop. I think I've made my point that arguing AGW based upon a 3 degree rise in atmospheric temperature is hogwash. So, you're arguing that a feedback loop has been going on, and we are enhancing that feedback loop by putting CO2 into the atmosphere. Somewhere in that feedback mechanism, there is an open thermodynamic system. It's not closed. Q accumulated = Q input - Q output. The earth, sea, and air all have their own control volumes around which to do this dynamic balance. Each of the Q input/output variables will have multiple driving forces. The dominant forces here will be evaporation, convection, and radiation. Since we are basically at equilibrium, Q accumulated is zero. Therefore, Q input = Q output. Again, you have not been able to explain why CO2 in practice will have a significant impact. I fully understand its insulating properties, but as far as I can see, it seems to be insignificant. Since this seems to be high school to you, why don't you whip up some calculations, and share the numbers with us.We are all engines of karma Quote Share this post Link to post Share on other sites lawrocket 3 #366 July 15, 2009 QuoteHow can you be both selfish and selfless at the same time? You cannot. Who does something without a benefit? Nobody. People may go work at the soup kitchen to make them feel better about themselves. A selfish reason. Selflessness is selfishness from a different perspective. QuoteJesus. Still playing? Jesus was a deity. Of course, he wanted to be loved and worshipped, but for the sake of others. QuoteGhandi. He was sick of discimination and troubles that he himself faced. He made South Africa/India better for him and his people. And he was their leader. They haven't made movies about the Indians shot dead in South Africa. QuoteMother Theresa Mother Theresa privately despaired that she did not get out of religion what she wanted. She was intensely proud, and deliberately fought against her pride her entire life. In a sense, she was fighting against herself to be, in her eyes, better. QuoteThe people who responded in the Hudson river when U.S. airways Flight 1549 crashed into it. No one there had time to think about self-interest when it happened. They just responded. Good point. My favorite example of an altruist and hero is Lenny Skutnik. Interesting point. QuoteActually, the U.S. was founded on individualistic goals. So, Americans typically are selfish. You've been reading way, way too much Ayn Rand. You should slow that down a little bit. I've never read Ayn Rand. QuoteIt sure looked like you were putting youself on a pedestal back there. Mr. genuine honest libertarian man. Perhaps. They are my observations on myself and on others. Quoteyour differences don't really matter-sorry man) I really don't think I can make much of a difference in the world. My differences also matter little. I can understand that. Quoteso now we both agree that the government is necessary even to a free-market. (making it NOT a free market) Yes. Freedom involves disputes, and arbiters for those disputes are necessary for efficiency. There is an irreconcilable tension between freedom and order. I admit that. QuoteThe public will "have to" eventually. Just like you will "have to" find some other method of transportation. Given enough time not even you will be able to afford gasoline. Yes. Given enough time I shall also be dead. I would prefer that such a thing not be prematurely forced via external political force. Nor would I prefer to have alternative fuels not yet commercially viable forced upon us. Especially considering that I am far from convinced that global warming - the reason for the proposal - will be headed off or even stalled by it. My wife is hotter than your wife.
