Ugh, NO! You're conflating two different things. Your body is being cooled beyond the amount of heat (work) that it produces. You are running cooler. Trap that cooling effect and you'll get hotter until equilibrium.If you measure the temperature on the surface of your skin, won't it go up while wearing a jacket? For exactly the reason you said, heat dispersion is being limited and "you are heating you".
The temperature on the surface of the Earth (skin) is partly due to the atmosphere (coat) trapping heat being released from the Earth (you).
According to climate alarm, the Earth would be an ice ball if it wasn't for GHG's. The reason they claim is that the solar input only heats to -15 C (or whatever the temp they claim it would be. Somewhere in the negative) So they are claiming that the Earth is only warm because they claim that "heat" is being captured and warming beyond the capability of the Sun. Meaning the energy from the Sun is only capable of heating the Earth to -15 C. By trapping the heat, you're only heating the COLDER air around it, not making the surface hotter. We've reached equilibrium until the Sun puts out more energy OR the albedo goes down or both.
Two different things. One (your body) is being cooled but if trapped in can heat up to it's heat potential. The other, the Earth, they claim is very cold, but insulation is allowing heat to multiply. Hence why I put in the statement above. Here it is again:
When a hot and a cold body are brought into contact with each other, heat energy will flow from the hot body to the cold body until they reach thermal equilibrium, i.e., the same temperature. However, the heat will never move back the other way; the difference in the temperatures of the two bodies will never spontaneously increase
