I can't say I have noticed any difference, but if the Inuits are saying it, I think we need to listen.

The eye piece used in the small aligning telescope in the telescope mount has reticles, depending on who made the eye piece and when, which will show where to place Polaris. It's to take into account for precession.
While our eyes can't see any huge change (because precession is something like 26,000 years), zooming in with a telescope will show slight movement.
RA and Dec's do change. If you use coordinates that were written down prior to the year 2000, those coordinates are referred to as the B1950 Epoch. Since 2000, we use the J2000 Epoch.
It's to account for precession.
BTW - you're not nit picking, you're asking questions, which is great!
As you know (having read many of your posts on Climate Change, heh), our sun drives our climate. The northern latitudes receive sun light at a much more oblique angle than areas closer to the equator.
That of course is a major part (but not all) that drives the climate in those areas. In order for the climate to change due to a change in angle of the sunlight, that angle would have to change a lot. More than precession allows for.
So can the position of the sun rising and setting change and the position of the stars change due to the Earth's "wobble" or precession? Of course.
But that change is very small over a very long period of time. And you're only going to notice it with things like telescopes or a sextant, and comparing it to previously recorded data. You'll see that over the last century these things have changed. But by very small amounts.
Someone "eye balling it" with just their eyes are not going to see that change....
Nunavut-based director Zacharias Kunuk (Atanarjuat The Fast Runner) and researcher and filmmaker Dr. Ian Mauro (Seeds of Change) have teamed up with Inuit communities to document their knowledge and experience regarding climate change. This new documentary, the world’s first Inuktitut language film on the topic, takes the viewer “on the land” with elders and hunters to explore the social and ecological impacts of a warming Arctic.

High tech sattilites are ok, I guess, for trying to figure out what nature is doing but actually observing nature year after year is a much more accurate way of knowing if nature is changing.
The Inuit describe the sun rising in a normal location but setting more south. If the Earth's tilt were involved both sunrise and sunset would be dislocated, not just the sunset. This is an important clue about what has been observed. It’s interesting that the same observations have been made by others. Those others are scientists who have described the effect as a sort of mirage caused by the encroachment of warm air into arctic regions.

Both you and SonOfTheLawOfOne have added a lot of value and quality discussion to this thread so thanks for that.
I hope you both earned applause for adding quality material to the boards.
Do Mods still receive applauds?

All the while the rest of the world is distracted by the CO2 AGW meme and what we must do to correct it .I would put more faith in the elders figuring out what they have to do to survive what seems to be a new (kind of) ice age .Too soon to tell how far the fluctuations in the earths climate may play out or for how long but we humans have a built in ability to survive even if it requires us eating our own . a reply to: UnBreakable

...and when the Inuits get drunk and rape their younger relatives we should? Oh right. Different case. Inuits have a really high rate of familial incest and alcoholism.
Oh well right? At least they know when the Earth wobbles, maybe cause its out of tune with their own wobble.

On an unrelated note, we should listen to the Chinese when it gets really cold, because they have dragons to heat up the Earth when it needs it.
