predicted that the axis might "wobble" slightly. Around the beginning of the 20th century astronomers noticed a small apparent "variation of latitude", as determined for a fixed point on Earth from the observation of stars. Part of this variation could be attributed to a wandering of the Pole across the Earth's surface, by a range of a few metres. The wandering has several periodic components and an irregular component. The component with a period of about 435 days is identified with the eight-month wandering predicted by Euler and is now called the

The exact point of intersection of the Earth's axis and the Earth's surface, at any given moment, is called the "instantaneous pole", but because of the "wobble" this cannot be used as a definition of a fixed North Pole (or South Pole) when metre-scale precision is required.

men, Ahwelah and Etukishook, but he was unable to produce convincing proof and his claim is not widely accepted. The conquest of the North Pole was for many years credited to US Navy engineer Robert Peary, who claimed to have reached the Pole on 6 April 1909, accompanied by
Matthew Henson Matthew Alexander Henson (August 8, 1866March 9, 1955) was an African American explorer who accompanied Robert Peary on seven voyages to the Arctic over a period of nearly 23 years. They spent a total of 18 years on expeditions together.
and four Inuit men, Ootah, Seeglo, Egingwah, and Ooqueah. However, Peary's claim remains highly disputed and controversial. Those who accompanied Peary on the final stage of the journey were not trained in esternnavigation, and thus could not independently confirm his navigational work, which some claim to have been particularly sloppy as he approached the Pole. The distances and speeds that Peary claimed to have achieved once the last support party turned back seem incredible to many people, almost three times that which he had accomplished up to that point. Peary's account of a journey to the Pole and back while traveling along the direct line – the only strategy that is consistent with the time constraints that he was facing – is contradicted by Henson's account of tortuous detours to avoid pressure ridges and open leads.

(around 23 September). When the sun is visible in the polar sky, it appears to move in a horizontal circle above the horizon. This circle gradually rises from near the horizon just after the vernal equinox to its maximum elevation (in degrees) above the horizon at summer solstice and then sinks back toward the horizon before sinking below it at the autumnal equinox. Hence the North and South Poles experience the slowest rates of sunrise and sunset on Earth. The

and its revolution around the sun. The direction of the Earth's axial tilt, as well as its angle relative to the plane of the Earth's orbit around the sun, remains very nearly constant over the course of a year (both change very slowly over long time periods). At northern midsummer the North Pole is facing towards the sun to its maximum extent. As the year progresses and the Earth moves around the sun, the North Pole gradually turns away from the sun until at midwinter it is facing away from the Sun to its maximum extent. A similar sequence is observed at the South Pole, with a six-month time difference.

, such that the time of day is more or less synchronised to the position of the sun in the sky (for example, at midday, the sun is roughly at its highest). This line of reasoning fails at the North Pole, where the sun rises and sets only once per year, and all lines of longitude, and hence all time zones, converge. There is no permanent human presence at the North Pole and no particular time zone has been assigned. Polar expeditions may use any time zone that is convenient, such as

Winter temperatures at the northernmost weather station in Greenland can range from about , averaging around , with the North Pole being slightly colder.

Reports have also predicted that within a few decades the Arctic Ocean will be entirely free of ice in the summer. This may have significant commercial implications; see "Territorial claims", below. The retreat of the Arctic sea ice will accelerate global warming, as less ice cover reflects less solar radiation, and may have serious climate implications by contributing to Arctic cyclone generation.

), Russia (ratified in 1997), Canada (ratified in 2003) and Denmark (ratified in 2004) have all launched projects to base claims that certain areas of Arctic continental shelves should be subject to their sole sovereign exploitation. In 1907 Canada invoked a "sector principle" to claim sovereignty over a sector stretching from its coasts to the North Pole. This claim has not been relinquished, but was not consistently pressed until 2013.

s and Western culture, Western folklore, the geographic North Pole is described as the location of Santa's workshop, Santa Claus' legendary workshop and residence, although the depictions have been inconsistent between the geographic and magnetic North Pole. Canada Post has assigned postal code H0H 0H0 to the North Pole (referring to Santa's traditional exclamation of "Ho ho ho!"). This association reflects an age-old esoteric mythology of Hyperborea that posits the North Pole, the otherworldly world-axis, as the abode of God and superhuman beings. As Henry Corbin has documented, the North Pole plays a key part in the cultural worldview of Sufism and Iranian mysticism. "The Orient sought by the mystic, the Orient that cannot be located on our maps, is in the direction of the north, beyond the north.". In Mandaean cosmology, the North Pole and pole star#In religion and mythology, Polaris are considered to be auspicious, since they are associated with the World of Light. Mandaeans face north when praying, and mandi (Mandaeism), temples are also oriented towards the north. On the contrary, South is associated with the World of Darkness (Mandaeism), World of Darkness. Owing to its remoteness, the Pole is sometimes identified with a mysterious mountain of ancient Culture of Iran, Iranian tradition called Mount Qaf (Jabal Qaf), the "farthest point of the earth". According to certain authors, the Jabal Qaf of Cosmology in medieval Islam, Muslim cosmology is a version of Rupes Nigra, a mountain whose ascent, like Dante Alighieri, Dante's climbing of the Purgatorio, Mountain of Purgatory, represents the pilgrim's progress through spiritual states. In Iranian theosophy, the heavenly Pole, the focal point of the spiritual ascent, acts as a magnet to draw beings to its "palaces ablaze with immaterial matter."
