It could be that the ice sheets are melting (reduced elevation ?), making it appear as though the sun and constellations are higher. The terrain is very changeable in the North, especially now. Some people are saying that the activity of ice breakers there is contributing to the melt too, by chopping up the ice, so it melts faster. The permafrost could be thawing and sinking the land, as the water drains out.
Either that or the earth is spinning out of control !
