I notice that at 4:30 PM on December 21 when I leave the office in Edmonton, Alberta it is no longer pitch dark as it was only a few years ago...only a deep dusk and not dark until almost 5 PM. That would mean the Northern Hemisphere is not as far away from the sun as it used to be on the winter solstice. Is there any evidence to back this up?
