The rest of us are unwilling to choose obvious lies for our fundamentals SID.
Says one of the biggest liars on the board....you are laughing stock crickham.....laughing stock.
the other thread was closed. I had already written this response so I'll add it here. no need to respond. I always think there should be some way to get through to you but I suppose it takes a certain amount trust and respect to actually read a comment for content, digest it, and make a pertinent answer. it's never happened before, I know it wont happen this time. hahahahahaha

You keep saying CO2 does nothing, then you say it does absorb IR, then you go back to saying it does nothing again.
Which is precisely what I mean...absorption and emission are nothing but absorption and emission...run a quantity of water that can easily flow through a big bore water pipe through that water pipe...the water went in...the water went out...what happened to the flow?...going through the pipe did nothing. You are claiming that the pipe is to small for the water to flow uninterrupted through the pipe...if the statement were true...then there would be a visible back up. If there is no back up, then clearly your claim that the pipe is to small to easily accommodate the flow is false. At some point, even you must admit that the claim was false...what might that point be Ian?
.
there you go again....giving radiation the properties of matter. the two are fundementally different. radiation doesnt 'back up'. it does not interact with other radiation except in the presence of matter.
are you saying that there is no green house effect at all? or are you saying that CO2 takes no part in it? or are you saying that increasing (or decreasing) CO2 makes no difference?
let's go with your incorrect version of physics where radiation = matter. you say there is no difference in the pipe whether the radiation stays in it a nanosecond or an hour. what about the 'weight' of the pipe? in the first case it is simply the weight of the pipe, in the second case it is the weight of the pipe plus an hour's worth of radiation. obviously different.
now let's turn that into a more realistic scenario. if the atmosphere did not absorb 15 micron IR it would be 'lighter' by 35W because the energy would disappear directly into space. less energy equals lower temperature by definition. a cooler atmosphere would then create less blackbody radiation, which means less energy is returned to the surface. or in your convoluted and incorrect understanding of the SLoT, more surface energy is lost because the temperature differential is greater. anyway you look at it both the surface and the atmosphere will equilibrate to a lower temperature by losing the 35W directly to space.
but the atmosphere does absorb the 35W of 15 micron surface radiation. this warms the boundary, and....at the other end, TOA, there is not 35W of 15 micron IR coming out. your 'pipe' keeps getting heavier and heavier.
BTW, many people think CO2 molecules absorb a photon, then re-emit it. this is incorrect. it takes roughly 10 times longer to absorb/emit than it takes to enter into a collision with another molecule, at the surface. CO2 absorbs a photon and adds to the general pool of energy by transferring it via collision. most CO2 molecules that emit a photon have been excited via a collision rather than by absorbing a photon.
as height increases in the atmosphere, density and temperature decrease. while less collisions happen, there is a great chance that an excited molecule will last long enough to produce a photon, and that photon will have a greater chance to escape because there are less molecules to capture it.
