Sun rises two days early - in Greenland
Discussion
My understanding is that the atmosphere has a 'lensing' (I might have made that verb up) effect. This can vary according to how dense the atmosphere is and on weather patterns, e.g. the variation of high and low pressure areas. This means that the sun apparently sets later than Newton might have thought. It also rises earlier than it 'should' but the gap between calculated and obsereved is not the same as setting normally due to the different temperatures and such.
I accept that as a scientific thesis this lacks a certain amount of detail but I was told this by a science lecturer at Sussex Uni when sitting on a patio watching the sun set when he was a wee bit drunk.
So the times of 'observed' sunrise and sunset depend on the weather.
No more detail to follow from me.

Could any of this have something to do with the Earth's axis tilt?
In theory yes but we would have noticed a comet or asteroid impact The changes to our planet's axial tilt which make it vary between 22.1 deg and 24.5 deg (currently about 23.5 deg), are smooth and continuous in a cycle of about 42000 years.

Earlier I said:
though of course refraction is pertinent to sunrise.
It would take a mind boggling amout of force to be impinged on the earth to affect its orbital tilt. If such a force had impacted the earth - either from outside (asteroid, planetoid impact) or from within the earth (massive volcanic eruption) I think we would not be here discussing it.

So errors of omission are OK.
Really? No.
The general intention is clear, and it is to mislead by assumption in a propagandised audience.

Are you kidding? about twice the global rate or something like that.Given the rampant substitution going on in news releases of regional and global temperatures...for the 'Arctic' as opposed to where actual temperatures are measured, as the man said is it basically a convincing idea to use land/city/Airport temperatures for temperatures at sea?
As to 'twice the global rate', you seem to be going off a 2004 article in No Scientist. Cherry picking of timescale perhaps - see my bold in the quote that follows. In that article, dated as it is, it's not clear where modelling ends and data (if there is any in use) begins, not on the first re-read anyway. Current reports (2010) shouild refer to El Nino...see below.
http://www.newscientist.com/article/dn6615-arctic-...
Meanwhile "according to the Danish Meteorological Institute, Arctic temperatures are currently below -35.15 degrees Celsius or -31.27 degrees Fahrenheit. That is more than five degrees below normal and the lowest reading since 2004. The slope of decline has also recently been quite sharp, dropping from 252K on January 1, a drop of 14 degrees in 22 days."
So is this twice as much warming thing actually half as much cooling?
As above temperatures in both polar regions are both below normal atm regardless of substitution colouring in by proxy. This false colour rendition appears to reflect reality more than most.
Meanwhile reports of high temperatures in 2010 also suffer from a typical error of omission, namely, reference to the cause: transient natural El Nino.
It's all a bit on the short timescale side anyway. Let's wait a few decades and see if a Dalton Minimum emerges and all that new ice heats up the world by virtue of the 2nd Law of Thermos Dynamics.

So it will be a bit spooky but with poorly developed characters and a laughable plot?Ayahuasca said:
