This extra gas is wasted. When the air is cold, there are more oxygen molecules per cubic foot, necessitating the use of more gasoline per cubic foot of air. Thus the need of enrichment of the mixture. After the engine warms up, all of this extra gas is converted into useable energy, but much of it is diverted to heating and powering things which do not need heating or powering in warmer weather, hence the loss. Also the warm up time is very costly.
