In the Arctic, the "new" winter sun would be initially rising and setting in the
south. The highest elevation due South of this town (looking on Google earth),
is a gradual slope of only about 230 feet. When you consider the distance we
are from the sun, I doubt that a little change in the snow pack would account
for the "two day" difference in the suns arrival.
This change would not be a direct factor with regards to our magnetic poles. It
would be an indication of a geographical change on the face of the earth with
regards to the position of the sun. If the earth and the sun have maintained
their relative positions to each other in the solar system, this town has
geographically rotated "two days" South in latitude.
The Arctic Circle is the latitude on the face of the earth that experiences one
24-hour day of daylight, and one 24-hour day of darkness each year. Any
geographical location south of the Arctic Circle (in the northern hemisphere),
will always have a segment of its day where the sun is visible. As you travel
to the latitude's north of the Arctic Circle, the length of the winter night,
and summer days are greatly extended. When I was working in the region of
Prudhoe Bay Alaska, the sun would usually set about one week before
Thanksgiving, and then finally rise again sometime around Super Bowl Sunday.
(Frequently we would miss the sunrise due to blizzards or ice fog.).
If the entire Earth's mantle has "slipped" two days South, instead of only
Greenland, this would no doubtably result in some type of climate change across
the entire face of the earth. It would not be global warming. It would be
global surface roaming.
