Ian Mauro, whose work was repeatedly quoted above, has an update at his website.

The visual changes in the placement of the sun in the arctic are real and can apparently be dramatic in some cases. This includes where exactly the Sun first peeks over the horizon after its disappearamce in Winter. Mauro’s thinking is that apparent changes in the position of the Sun and stars is due to a change in atmospheric refraction. In other words, this is a purely optical phenomenon whose ultimate cause is global warming.
You should realize that if you live in regions closer to the equator, then when you see the sun disappear at the end of a sunset, the Sun is already geometrically about 5 degrees below the horizon. The amount of this displacement is temperature and (pressure) sensitive. In the arctic, the Sun is just barely grazing the horizon toward the end of winter, and changes in temperature and uneven terrain could cause a big difference in the location (and timing) of its first appearance.
On another note, if you think that global warming is a hoax, just watch this video.
