Yes, it can. Partly because of the fuel and partly because of more idle time.
Another theory of mine is that the colder air keeps the engine from warming as quickly, mostly because the incoming air charge is colder and diesels use lots of air. Therefore, either the computer is allowing for more fuel or the engine uses more fuel to keep warm. Might be BS...just some of the ramblings in my mind.
As for an actual reason, I don't have it...these are just my guesses.
