Because In December the north pole points away from the sun and does not receive any sunlight
North Hemisphere
If we are talking about solar heating it warms mostly the equator. If we are talking about actual radiation we are least protected from it at the North and South pole. So even though the radiation itself may not be directed at the poles that is where a person would experience it the most.
North Pole
In Raleigh, North Carolina, it was a white Christmas.
The 'Northern Lights' (also known as the 'Aurora Borealis') is caused by the interaction of solar radiation with molecules in the Earth's atmosphere. Much of the Sun's radiation is deflected by the Earth's magnetic field. The magnetic field can be imagined as lines of force coming out of the Earth at the poles and running around the globe, almost parallel to the surface. The effect is most noticeable at the poles (there is also a 'Southern Lights, the 'Aurora Australis') because (some of) the radiation is deflected by the magnetic field towards the surface of the earth at the poles.
It may have fewer hours of daylight, but it certainly doesn't receive less radiation.

The poles are located at 90 degrees latitude. They are located at that part of the Earth's surface which is consistently the furthest from the the sun's heat and light radiation. The locations also receive radiation which has travelled the greatest distance within the atmosphere within which to be absorbed. These locations are, therefore, the coldest regions on the Earth's surface.

I don't know, and I don't care. Yes
Because land masses emit radiation causing the land to cool. Land cools quicker than water. The farther north you go toward the poles the less direct sun radiation you receive therefore the heat for the sun is less intense. the combination of earth emitting radiation and less intense solar radiation causes the higher latitudes to be colder.
Yes. You would also have exactly the same experienceif you moved toward the south pole instead.
Yes, it usually snows in December in North Dakota.
Moonlight and atmosphere.
On December 24th in the North Pole-it is completely dark. No sun.
Actually the warmest are found closer to the tropics (23° North and South of the Equator). This is because those areas get sunlight directly overhead where the radiation of the Sun passes through the least atmosphere and has the greatest energy.
