North Pole

The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is the northernmost point on the Earth, lying antipodally to the South Pole. At the North Pole, all directions point south, and all lines of longitude come together.

The North Pole sits in the middle of the Arctic Ocean, covered by shifting sea ice. Unlike the South Pole, which is on land, the North Pole is far from any permanent settlement. The closest land is Kaffeklubben Island, off the coast of Greenland, while the nearest inhabited place is Alert on Ellesmere Island, Canada.

People have tried to reach the North Pole since the late 1800s. The first undisputed group to reach it was the airship Norge in 1926, led by Roald Amundsen. Others had claimed to get there before, but later reviews questioned those claims. The first people to walk to the North Pole were a Soviet group in 1948, and the first to drive there over the ice were a group using snowmobiles in 1968.

Precise definition

The North Pole is the point where the Earth's axis of rotation meets its surface, making it the northernmost point on our planet. People used to think this point was fixed, but we now know the Earth's axis wobbles slightly. This wobble causes the North Pole to move a few meters over time. Scientists have special ways to track these changes and define the exact position of the North Pole at any moment.

Exploration

Many people believed the North Pole was surrounded by water, making it seem like a good place to explore. Early explorers used ships to try to reach it, often facing thick ice and harsh conditions.

Some famous early attempts include British naval officer William Edward Parry reaching a high latitude in 1827, and the Polaris expedition led by Charles Francis Hall in 1871, which ended sadly. Other notable journeys include Fridtjof Nansen’s ski expedition in 1895 and Salomon August Andrée’s balloon attempt in 1897, which also did not succeed.

Later in the 20th century, many more people tried to reach the North Pole. Some used airplanes, like Richard E. Byrd in 1926, while others traveled on foot with dog teams, like Wally Herbert in 1969. Submarines also visited the area under the ice. By the 21st century, trips to the North Pole became more common, with tourists and scientists both making the journey.

Time and day and night

At the North Pole, the sun stays above the horizon all day long during the summer and stays below the horizon all day long during the winter. The sun rises around March 20th and moves slowly across the sky until it reaches its highest point around June 21st. After that, it begins to sink lower each day until it sets around September 23rd. When the sun is visible, it moves in a circle around the sky instead of rising and setting like it does closer to the equator.

There are different kinds of twilight—light before sunrise and after sunset—that last for a few weeks each. These special patterns happen because the Earth leans at an angle and travels around the sun. The North Pole points toward the sun in summer and away from it in winter. Since the North Pole does not have a specific longitude, people there choose a time zone that is convenient for them, like Greenwich Mean Time.

Climate, sea ice at North Pole

The North Pole is warmer than the South Pole because it sits at sea level in the middle of the ocean, which helps keep it warmer. Even though it is covered in ice, the northernmost weather station in Greenland has a climate where summer temperatures can just barely get above freezing.

Winter temperatures at this weather station can be very cold, ranging from about −50 to −13 °C, with averages around −31 °C. Sometimes, during special storms, temperatures can get much warmer than usual. For example, in December 2015, a storm caused temperatures to reach nearly freezing at a buoy near the North Pole. Summer temperatures usually hover around freezing, and the warmest temperature ever recorded at the North Pole was about 13 °C, which is much warmer than the warmest temperature recorded at the South Pole.

The sea ice at the North Pole is usually about 2 to 3 meters thick, but this can change quickly due to weather and climate patterns. Scientists have noticed that the ice has been getting thinner over recent years, possibly because of global warming. Some predictions suggest that within a few decades, the Arctic Ocean might have no ice at all during the summer, which could change how the area is used and affect the climate.

Flora and fauna

Polar bears rarely travel beyond about 82° North because there isn’t much food, but they have been seen close to the North Pole. Ringed seals and Arctic foxes have also been spotted nearby.

Birds like the snow bunting, northern fulmar, and black-legged kittiwake have been seen at or near the Pole. Some fish live in the waters there, but not many. During a dive to the seabed in 2007, a sea anemone, shrimps, and amphipods were found.

Territorial claims to the North Pole and Arctic regions

Main article: Territorial claims in the Arctic

No country officially owns the North Pole or the Arctic Ocean around it. The five nearby Arctic countries—Russia, Canada, Norway, Denmark (through Greenland), and the United States—can control waters up to 200 nautical miles from their coasts. Beyond this area, the ocean floor is managed by the International Seabed Authority.

Countries that have agreed to follow the United Nations rules for ocean areas can ask to control parts of the ocean floor beyond their 200-mile zone. Norway, Russia, Canada, and Denmark have all started projects to support their claims to parts of the Arctic ocean floor. Canada also once claimed a path to the North Pole using a special rule, but this claim is not strongly used today.

Cultural associations

In many children’s stories about Christmas, the North Pole is thought to be where Santa Claus lives and works. Some even give it a special postal code, H0H 0H0, inspired by Santa’s famous laugh, “Ho ho ho!”.

The North Pole has also been important in many ancient beliefs. Some traditions see it as a sacred place connected to spiritual ideas and special meanings. For example, in Sufism and Iranian mysticism, the North holds a mysterious and special place. In Mandaean cosmology, the North Pole and the star Polaris are seen as symbols of light and hope.
