The general argument however is being discussed by rasmus in the context of
planetary energy balance: the impact of additional CO2 is to reduce the outgoing longwave radiation
term and force the system to accumulate excess
energy; the imbalance is currently on the order of 1.45 * (10 ^ 22) Joules / year over the globe, and the temperature must rise allowing the outgoing radiation
term to increase until it once again matches the absorbed incoming stellar flux.
