Have you considered that the Dunning–Kruger effect might be in play here? You're making lots of big claims and insisting everyone who disagrees with you doesn't understand physics. I have a degree in astrophysics and I've worked quite hard to get through thermodynamics courses. I'm quite confident that I do understand the thermodynamics involved here. Your argument seems to boil down to:

- The fact that you don't understand the mechanism through which CO2 would heat the atmosphere, and therefore you think it isn't happening.
- You reject every single climate model because of the simplifying assumptions and "bad code". Given that simplifying assumptions are necessary to do modeling and the amount of conspiratorial thinking in your other comments, I suspect that there aren't any assumptions you would agree with.
- You admit that warming is happening, but don't consider that to be evidence in favour of the models (even though they fit the data quite well). You claim they fit it poorly, well, let's see that study then!

> You skipped the part where I explicitly concluded that the effect comes from the difference in temperatures. I don't ignore it, I first understand the zero order - at uniform temperatures, there is no effect of CO2. Which leads to an understanding that if CO2 does indeed make a difference, it is the result of the temperature differences.

This is a vacuous statement.

> Then the part where I'm not at all certain about which direction the effect should be, is because while CO2 decreases thermal conductivity by radiation, it increases thermal conductivity by convection because the heat capacity is higher for CO2. Which is actually a much better intuition if you want to understand how does water vapor seems to have such negligible effect despite the fact it is a "greenhouse gas" and "absorbs much more heat".

Your lack of understanding is not a flaw in climate science.

> You want me to point out bugs? There are like 20 different climate models. I've seen heat capacity being constant independent of pressure, temperature, CO2, density, etc. Not just heat capacity, but also other "constants". Not in a single place because the code is a mess, they actually have several different modules with different constants, so say the radiation simulation is extremely detailed mess that's completely unreadable, and the cloud simulation just starts all over with their own different constants.

This is just you repeating what you said before. The code quality is not relevant unless you point out a bug.

> I'm sorry, but it is your thermodynamic intuition that's completely wrong. Equilibrium to you means "things stop moving". That... not how thermodynamics works at all. The reason that ordinary things look like they are "not moving" in equilibrium in your everyday life is because they do move, but at scales much smaller than you. Do the Brownian motion experiment.

I never made any such claim, nor did I imply that. Strawman argument.

> The models don't have any significance beyond this bit or maybe two bits if you try to be generous about their abysmal performance regarding temperatures.

What do you mean by this? Many of the models fit the warming in the recent past quite well. This process is called hindcasting.
