The examples of Mercury vs Venus are about the physical mechanisms where the atmosphere influences the temperature in a profound way.

Notice how the denialists don't really talk about physics? For the scientists, the physics are central to all aspects of earth science from the beginning (in all fields, far before global warming was a policy issue) and are the unifying, predictive bedrock of truth.

Precisely from a physics perspective, there is no comparison between Earth and Venusbecausethe atmospheres are so different.

The laws of physics are the same on Earth as Venus.

I have made fluid models and tested them,including under turbulent conditions.

What difference does the composition of the atmosphere make to the surface temperature of a planet, and why, and how would one compute that?

The composition of the atmospheres of Earth and Venus (& any planet for that matter) has a direct impact on both atmospheric and surface temperature. It is controlled by pressure/density of the composing gases and solar radiation and planet's emissivity/albedo. This can be done with well understood thermodynamics and fluid/heat transfer calculations

What we cannot do is predict in the future temperature changes due to minute changes in atmospheric composition ( as is the case with parts per million). Planetary orbital variations and changes in solar output play a far, far larger role, as logic (and physics) would dictate

The fact you have to ask the question exposed your abject ignorance, and gross inability to even Google the topic.

Deny ignorance.

Both things can affect it.

It's just like heating your house in Winter.

Suppose instead of wood furnace, someone is shooting a yellow laser through your window and that is hitting a rock and heating it up. Let's just suppose that were your heating system.

The insulation on your house matters just as much as the power output of your heating system. If you increase the intensity of the laser, that will heat up your house. But also if you close the door so you're not letting as much of the heat escape, that will heat up your house too.

They're both important.

mbKennel :

The issue is that light arrives at a different frequency than it leaves. So what is important is the percent transparency to both frequencies (or ranges of frequencies.) It will be somewhere between 0 and 100%, but not at either extreme.


Yellow light from the Sun comes in. Then it is absorbed by rocks and stuff. They heat up, and emit infrared light back toward space.

So like if yellow Sunlight is arriving at 65% transparency, but the infrared light is leaving at 55% percent transparency, then 10% of the energy is being trapped.

Of course, only so much in total will ever get trapped. As the planet gets hotter, it radiates more and more infrared per second, but the more insulated it is, the hotter it has to be in order to get it all to radiate away.

(Once it gets hot enough it reaches an equilibrium where it is radiating the same amount of energy as it receives. Like if you were spending all the money you make, but had some money in savings. The savings is how hot you are right now. But you may be taking in and emitting heat but staying at that temperature.)
