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?

Loise -
I suspect that you are the victim of the amateur astronomers' nemesis - creeping light pollution due to surrounding city lights, etc. Depending on the cloud cover or lack of it, this could be further amplified or damped out.

there's no information to help the concept the Earth's axial tilt or orbit has replaced in any respect interior the previous twelve months. There are small fluctuations interior the axial tilt and Earth's orbit, yet those could volume (at maximum) to 3 milliseconds distinction, no longer adequate for us to word. the adaptation you notice must be with the aid of diverse climate from final twelve months. as an occasion, if final twelve months it grow to be a clean sky and this twelve months there are clouds, those clouds will mirror the streetlights and different outdoor lighting fixtures in a city, making it look brighter.

Also if you go to the site provided by Morningfoxnorth you
see moonrise was at 1300 hours so the sky would have some light in it, plus there is still at 1630 some civil twilight left

No, you're misremembering. Or thinking about Dec. 21 in a different city.
