In an eA analysis of Earth's radiation budget, what happens to outgoing longwave radiation when global surface temperature rises under fixed greenhouse-gas concentrations?

Outgoing longwave emission increases roughly with the fourth power of temperature (Stefan–Boltzmann), providing a negative feedback that tends to restore energy balance Outgoing longwave radiation permanently falls to zero once temperature rises Outgoing longwave radiation becomes independent of temperature Only albedo can change; longwave emission is fixed by solar constant alone

Correct Answer:

Outgoing longwave emission increases roughly with the fourth power of temperature (Stefan–Boltzmann), providing a negative feedback that tends to restore energy balance
