With the current GHG content in the atmosphere, more solar energy arrives than
leaves via radiation -LRB-.85 + / -.15 Watt / m ^ 2), which raises the heat content of the terrestrial system, i.e., the average temperature over the whole earth + oceans + atmosphere.
To my way of reasoning, if the basics of the EFC is correct, then it would be reasonable to accept that the result of the 168 W / m ² absorbed by the surface would be that (24 +78) = 102 W / m ² are leaving in the form of thermals and «evapo - transpiration» and then the remaining energy 66 W / m ², after having done it's job, would
leave via radiation.
Not exact matches
Practically all energy entering the ocean is
radiation but the majority
leaves via evaporation.
I accept the idea that for a system surrounded by a vacuum when
radiation - rate - equilibrium is reached, the amount of energy per unit time
leaving a system
via radiation is equal to the amount of energy per unit time entering the system.
Only now heat can
leave the black body
via conduction and convection as well as
radiation, so I don't want to say the black body reaches
radiation - rate - equilibrium, rather it reaches energy - rate - equilibrium.
«All the energy that enters or
leaves the Earth system does so
via radiation at the top of the atmosphere.
Energy (ie warmer water) can convect upwards all it likes but it can only
leave * through the skin
via evaporation or
radiation which (I believe) is the limiting factor.
... you say that most of the energy
leaving the system
via IR emission (from CO2 in your example) is sourced from insolation, which would mean that only a small portion of the escaping CO2
radiation energy originates from earth's IR.
BPL (84) you say that most of the energy
leaving the system
via IR emission (from CO2 in your example) is sourced from insolation, which would mean that only a small portion of the escaping CO2
radiation energy originates from earth's IR.
Once the rate that energy
leaves the object
via radiation equals the rate at which thermal internal energy is being generated, the temperature of the surface of the object will cease to change and settle at a fixed value.
