Ah, I see. That makes a lot more sense now. Except it also raises some more solar questions.
If the sun is lower in the winter, wouldn't it also be closer to the land, giving it more light and radiant heat, making winter actually hotter than summer?
What mechanism makes the sun go higher/lower in accordance with the seasons? ("Magic" is acceptable, I guess.)
What happens to the sun at night? So if I were standing on the eastern edge of that little gray island in the far West, and the sun sank below the level of the land, what do I see? Is it still bright for most of the night because the sun circles back around under the continent where I can see it? Or does it abruptly go out and utterly vanish until the dawn?
Lastly, most of the land is within a few miles of an ongoing nuclear fusion reaction, so are there any problems with radiation?
