The fog acts as a blanket, trapping the infrared radiation emitted by the Earth, leading to an enhancement of the greenhouse effect. This means that the heat already present in the atmosphere is trapped, preventing it from escaping into space, ultimately leading to warmer temperatures than would be experienced without the fog.
