Yeah, you'll notice that your "massive" 22°F is the difference between direct sunlight and no sunlight. Do you think there's another sun to take away after the first one, to get rid of even more sunlight and drop the temperature another 22°?
Why don't you believe that physical materials are capable of holding heat energy? Why did you latch on to atmosphere and ground instead of the biggest energy store on the planet, the ocean (you don't need to answer that we know it's because those are the ones I named)? Why do you think that the temperature difference between day and night - sunlight and no sunlight - is the same as the general rate at which energy is lost from the planet? Have you not ever been outside at night to discover the largest part of the temperature drop happens as soon as the sun disappears?

You're doing a very good job of the typical liberal application of raw, familiar logic to a new situation, but the only part of it you actually understand is that the sun supplies lots of energy, and haven't made it any further than that.
