Let’s add two more objections to this partial visualization of the Earth System.
1. Where are the storages? Oceans store and release huge amounts of energy. Elaborate your views of the energy/radiation balance.
2. Energy is not just radiation. Earth System is more complex than that. For example, absorbed radiation energy may result in increased cloudiness that has impact on who much radiation reaches the earth. Ignoring major part of the system does not help in believing your conclusions.
