Mercury technically doesn't even have weather.

You're more or less there.
The side not receiving light, and hence energy as ev = hf, thus no increase in heat as the kinetic energy is directly proportional to the thermodynamic temperature, the only thing it has to transfer the energy it gained is the external environment; space. Which is about 2.7k anyway, not far off absolute zero, it loses a large portion of the energy by radiating it out, as per the 1st law of thermodynamics as everything tends to chaos, there must be a transfer of the energy to tend to a thermal equilibrium.
An atmosphere would enable transfer of energy to those molecules, slowing down the exchange of heat, hence retaining some heat and not being - 100.15kelvin which is colder than the ice queen.

No shit is proportional, temperature is just a measure of the average kinetic energy the molecules of an object have

Hence, the mean kinetic energy is directly proportional to the thermodynamic temperature.
Imagine a box with 3 molecules, they each move a distance of 2d, with momentum 2mv, the time taken is t = 2d/v, hence the collisions per second (force exerted per collision) are v/2d , f = v/2d. v/2d * 2mv = f = mv^2/d and as p = f/d^2, le algebra and we get p = mv^2/v , for 3 molecules the no. of moles is 3, so P = nmv^2/3v, but if N = 3n then P = Nmv^2/3v, and m/v = density, so the pressure = 1/3 density * v^2, or in terms of the mean square speed, c^2.
Following back the equation, p = 1/3 pc^2 = Mc^2/3V where M is the total mass of the gas.
Gives us 3pV = Mc^2, but as you know from the gas law, pV = NkT, so 3pV = 3NkT
Hence MC^2 = 3NkT, and as the kinetic energy is 1/2mv^2, the mean kinetic energy of one molecule is E = 1/2 M/Nc^2 = 3/2KT
Hence the mean kinetic energy is directly proportional to the thermodynamic temperature, the constant being 3/2 boltzmann constant. This is mathematically speaking, my physics isn't too good.

Dunno, I was typing it out quickly.
I meant n molecules, with total number of molecules being N, which is 3n if we have 3 molecules. I guess I said moles because when using the gas equation, if derived using avogrados law, you use n as moles so often. It's just the letter representation, I managed to get it mixed up because I was typing out too quick
