There's «gee, I hope when I die I go somewhere special,» and then there's the fact of it: you're in a box, buried in the ground, your body breaks down and gets
absorbed by the planet eventually, and your nutrients are used to make a plant grow or something to that effect.
More specifically, they will be limited to the solar energy that is normally

absorbed by the planet.
Additionally, much of the heat
absorbed by the planet is channeled into melting solid water, and that heat is a massive quantity, given the mass of ice being melted and the fact that there's essentially no temperature change as the melting takes place (heat to change phase, as opposed to raising temperature).
This is because energy leaving the planet must be balanced by energy being
absorbed by the planet from the sun.

absorbed.

For example, it is assumed that
by the gravity between the
planets and gas of the disk, the
planets will be pulled to the central star and finally
absorbed into it.
More than 90 percent of the excess heat trapped
by greenhouse gas emissions has been
absorbed into the oceans that cover two - thirds of the
planet's surface.
The Arctic is warming more than twice as fast as the rest of the
planet, because as ice melts at the top of the world, there is less of it to reflect sunlight back into space, so more of it is
absorbed by ocean waters; more
absorbed sunlight means even warmer temperatures, which means more ice melt a circular process known as Arctic amplification.
That incoming light is
absorbed by hydrogen atoms and converted to heat energy, NASA stated, and this steady conversion of light - to - heat makes the
planet appear to be pitch - black to onlookers, the researchers found.
[2] The doppelganger revived herself
by absorbing massive amounts of Phazon in her storage room, further suggesting that the creature is indeed the Metroid Prime that was somehow resurrected after its downfall on
Planet Tallon IV.
Thus, heat
absorbed by the oceans accounts for almost all of the
planet's radiative imbalance.
The point is that although selection rules will determine whether a molecular vibration can
absorb IR radiation, and is obviously necessary for a complete discussion of the issue, the issue can be simply addressed
by consideration of the frequencies of absorption
by the gas and emission
by the
planet.
There are subtle effects such as the
planet losing more heat from the open sea than from ice - covered region (some of this heat is
absorbed by the atmosphere, but climates over ice - covered regions are of more continental winter character: dry and cold).
But
by changing the
planet's albedo through a large seasonal variation, the total insolation is changed — more sunlight is reflected back into space without being
absorbed as heat.
The skin layer
planet is optically very thin, so it doesn't affect the OLR significantly, but (absent direct solar heating) the little bit of the radiant flux (approximatly equal to the OLR) from below that it
absorbs must be (at equilibrium) balanced
by emission, which will be both downward and upward, so the flux emitted in either direction is only half of what was
absorbed from below; via Kirchhoff's Law, the temperature must be smaller than the brightness temperature of the OLR (for a grey gas, Tskin ^ 4 ~ = (Te ^ 4) / 2, where Te is the effective radiating temperature for the
planet, equal to the brightness temperature of the OLR — *** HOWEVER, see below ***).
