The North Pole, located at the northernmost point on Earth, is surrounded by the Arctic Ocean and is known for its extreme environmental conditions. Here are some key truths about the North Pole:
Geographic and Environmental Facts
- Location: The North Pole is situated at 90 degrees North latitude and is the point where all longitudinal lines converge.
- Ice Coverage: The North Pole is covered by shifting sea ice that can vary in thickness and extent. It does not have a permanent landmass beneath it, unlike the South Pole, which is located on the continent of Antarctica.

Geographic and Environmental Facts
- Location: The North Pole is situated at 90 degrees North latitude and is the point where all longitudinal lines converge.
- Ice Coverage: The North Pole is covered by shifting sea ice that can vary in thickness and extent. It does not have a permanent landmass beneath it, unlike the South Pole, which is located on the continent of Antarctica.
- Climate: The North Pole experiences extremely cold temperatures, particularly during winter, with average temperatures in January around -40°F (-40°C). In summer, temperatures can rise to around 32°F (0°C) but typically remain below freezing.
- Daylight Variation: The North Pole experiences polar day (midnight sun) in the summer, where the sun does not set for about six months, and polar night in winter, where the sun does not rise for about six months.
Ecological Aspects
- Wildlife: The region is home to various species adapted to cold climates, including polar bears, seals, and migratory birds. The surrounding waters are rich in marine life, including fish and plankton.
- Ecosystem Changes: Climate change is significantly impacting the Arctic environment, leading to diminishing sea ice, altered habitats, and shifts in wildlife populations.
Human Activity and Exploration
- Exploration History: The North Pole has been a site of exploration since the late 19th century, with notable explorers like Robert Peary and Roald Amundsen claiming to have reached the pole in the early 1900s.
- Scientific Research: The region is of great interest for scientific research, particularly regarding climate change, oceanography, and polar ecosystems. Various research stations and expeditions are conducted to study these topics.
Political and Economic Considerations
- Territorial Claims: The North Pole and surrounding Arctic regions are subject to various territorial claims by countries such as Canada, Russia, and the United States, primarily due to potential natural resources like oil and gas.
- Shipping Routes: As ice melts due to climate change, new shipping routes are becoming more accessible, raising geopolitical and environmental concerns.
Cultural Significance
- Cultural Impact: The North Pole has a significant place in popular culture, often depicted in literature, films, and folklore, particularly in relation to Santa Claus and holiday traditions.
These truths highlight the North Pole's unique characteristics and the challenges it faces in the context of global changes.
Our Planet’s Restless Poles
Are you ready? Hold on to your hat! The interesting fact is that what we refer to as the North Pole today used to be the South Pole! I can see you shaking your and mumbling to yourself: You are kidding me, right? No, I am not and here is why:
Earth’s magnetic fields
When scientists studied geologic records, they found out that our planet’s magnetic field occasionally reverses its polarity.
Evidence of magnetic polarity reversals can be observed in lavas or sediments; when they solidify, they often preserve a signature of the ambient magnetic field at the time of deposit

Are you ready? Hold on to your hat! The interesting fact is that what we refer to as the North Pole today used to be the South Pole! I can see you shaking your and mumbling to yourself: You are kidding me, right? No, I am not and here is why:
Earth’s magnetic fields
When scientists studied geologic records, they found out that our planet’s magnetic field occasionally reverses its polarity.
Evidence of magnetic polarity reversals can be observed in lavas or sediments; when they solidify, they often preserve a signature of the ambient magnetic field at the time of deposition.
Scientists collected rock samples from the cliffs of the so-called Khorbusuonka section in Siberia. Iron-rich minerals in these rocks record magnetic signatures from a slice of Earth's history some three million years long.
Incredible as it may seem, the magnetic field occasionally flips over! The geomagnetic poles are currently roughly coincident with the geographic poles, but occasionally the magnetic poles wander far away from the geographic poles and undergo an "excursion" from their preferred state. Earth's dynamo has no preference for a particular polarity, so, after an excursional period, the magnetic field, upon returning to its usual state of rough alignment with the Earth’s rotational axis, could just as easily have one polarity as another.
The Earth's magnetic field has been weakening over the South Atlantic (blue region). Image credit - ESA/DTU Space
These reversals are random with no apparent periodicity to their occurrence. They can happen as often as every 10 thousand years or so and as infrequently as every 50 million years or more. The last reversal was about 780,000 years ago.
Reversals are not instantaneous; they happen over a period of hundreds to thousands of years, though recent research indicates that at least one reversal could have taken place over a period of one year.
Oh, by the way, if that were to happen that fast again, we would be all toast!
Here is your bonus trivia: Today our compasses are just pointing to one pole at a time because there's a dominant two-pole system; but sometimes, Earth doesn't always just have a single magnetic North and South Pole.
These screenshots from a NASA animation of a reversal show the chaotic nature of a reversal, as the poles take time to stabilize.
Evidence suggests that, for hundreds to thousands of years at a time, our planet has had four, six, and even eight poles at a time.
This is what has happened when the magnetic poles flipped in the past. And when it happens again, it won't be good news for humans.
Those who might have further interest in the topic can watch the following video “Secrets in Stone” by USGS for interesting details.

Unlike the South Pole, the North Pole doesn't have steady land. It's actually a sheet of ice that floats on top of the Arctic Ocean. According to National Geographic, the ice is about 2 or 3 meters thick. So, contrary to what some may imagine, it's not an ideal place for skiing and snowboarding or for reindeer games.
Here are some facts :-
1.There are four North Poles. The terrestrial North Pole is a fixed geographic point that’s diametrically opposed to the terrestrial South Pole on our planet’s axis of rotation; it’s the top of the spinning top that’s Earth.
2. The North Dip Pole is the spot where the geomagnetic field is perpendicular to the Earth’s surface, “dipping” to meet the big, rotating ellipsoid that is our planet.
3. The North Dip Pole isn’t stationary. Just in the last century, it has migrated northward from a point in Canada at about 71 degrees latitude to its current position, about 85 degree

2. The North Dip Pole is the spot where the geomagnetic field is perpendicular to the Earth’s surface, “dipping” to meet the big, rotating ellipsoid that is our planet.
3. The North Dip Pole isn’t stationary. Just in the last century, it has migrated northward from a point in Canada at about 71 degrees latitude to its current position, about 85 degrees north, in the Arctic Ocean.
4. There’s a South Dip Pole, too, but the North Dip Pole doesn’t have to be antipodal, or diametrically opposed, to it. Right now they’re off by more than 20 degrees latitude.
5. When your compass points north, it’s pointing to the North Dip Pole, which is also called the magnetic North Pole.
6. The geomagnetic North Pole is a different thing altogether. It’s calculated using mathematical models based on an imaginary line running through the geomagnetic center of Earth.
7. Over the past century, the geomagnetic North Pole has migrated from Greenland to Canada.
8. So who cares about geomagnetic North? Aurora hunters, for starters. The most spectacular views of the Northern Lights occur in an oval ring centered around the geomagnetic North Pole.
9. Auroras are cool, but if you want to have some real fun, position yourself at the magnetic North Pole with a compass. If you hold the compass horizontal, the needle will do one of three things: point to the same spot as the last time you used it, spin slowly before stopping at a random point or point to anything magnetic that you happen to be wearing.
10. We promised a fourth North Pole. That would be North Pole, Alaska, incorporated in 1953. The Fairbanks suburb is hundreds of miles south of the other three North Poles.
11. While the Alaskans who live in North Pole don’t live near any of the real North Poles, a globe-hopping do-gooder beloved by many does. We’re talking, of course, of pulp fiction hero Doc Savage, Man of Bronze. Since 1933, the scientist with superpowers has starred in a long line of comics, magazines, paperbacks, radio series and even a 1975 B-movie. Savage’s Arctic retreat, the Fortress of Solitude, is said to be near the terrestrial North Pole.
12. Apparently, Savage has a time-share thing going on at the fortress with Superman, who also relaxes there (Jerry Siegel and Joe Shuster, Superman’s creators, were big fans of the doctor and borrowed a bio detail or two).
13. Staking out a different kind of property claim, a Russian submarine planted that nation’s flag at the bottom of the Arctic Ocean, at the terrestrial North Pole, in 2007.
14. The Russians may have planted a flag, but American submariners got there first: The USS Nautilus did a polar drive-by in 1958.
15. Robert E. Peary beat the Nautilus by nearly half a century. His team made what he claimed was the first recorded trip to the terrestrial North Pole in 1909 by dog sled.
There are many high latitude lands which have the nickname, “land of the midnight sun”. The truth is that extends much further than the land to almost all of the Arctic ocean. With this comes seasonal summer melt. There are at least two sightseeing aircraft that safely landed at the North Pole and then slowly fell through spring ice.
That said the brightest part of the day during a high latitude summer is at most like a “mid-to-late” afternoon sun compared to most places on the Earth.
With these mild summers also come very cold, very dark winters. These winters are not quite as cold as high nort

With these mild summers also come very cold, very dark winters. These winters are not quite as cold as high north “inland winters” as the ocean is near freezing and is never more than a few meters away from the surface. The ocean is constantly losing heat through the ice.

If you look at the elevation or sea-ice free-board, one could extrapolate a “lead of first year sea ice” all the way to the pole this August past. Again, it’s always shifting and circulating.
The North Geographic Pole and the North Magnetic Pole are not in the same location.
The geographic North Pole is under 3000 meters of water and ice which is constantly moving.
There is a Twin Otter plane on the bottom of the ocean very close to the geographic north pole . It broke through the sea ice and sank

Ice exists, and almost nothing happens. The ice drifts past at a few miles a day, and no doubt fish get on with their lives underneath. But it takes clever instruments to know which bit of the icy waste is the North Pole today.
There are actually 3 north poles: True North, magnetic north, and geomagnetic north. The last one sits in Canada. The military outpost of Alert, Nunavut, Canada is the closest permanently inhabited place to the True North Pole.
Therefore, Santa Claus is Canadian.
Actually it maybe won’t be too long before the Noth Pole becomes the South Pole.
I tried to change around 40,000 years ago but the last full swap was about 780,000 years ago, so we’re a bit overdue for a pole reversal based on the established pattern. The period is normally between 200,00 and 300,000 years.
The planet’s magnetic field is already shifting, which could signify the poles are preparing to flip,
That will cause us a few little problems.
Santa, et al, are in big trouble. The whole place is melting. The workshop is in danger. People are wrecking the world.
Superman’s fortress of solitude is in similar trouble. Lex Luthor is ecstatic.
It’s cold there. All things are south from the pole wherever you take your first step. The ice sheet is much smaller than it was when I was a kid. It isn’t exactly where a magnetic compass points because the magnetic field isn’t the same as the geographic north.
Ice on the surface. Salt water underneath the ice. And a Russian flag on the sea bed. Not a popular tourist destination.

It is the Northern most area of the planet. What do you mean by real truths.
Before I could attempt to answer your question is My return question is “about what UNtruths are you questioning?” Were I to know them, I could address them individually. But, trying to answer by “guessing” what I should say would be unproductive and not serve you well.
That it is the northern end of the Earth's rotational axis, that it is very cold, that is has 6 months of darkness in the winter, that it is a floating ice sheet….
It is too far north to see the aurora!
You can go to the North Pole. It’s not nearly as harsh the South Pole.
The big difference…it’s in the middle of the Arctic Ocean. Not on land. Most of the time sea ice….some years it breaks up a bit and areas of open water.
There is no way of accessing the North Pole unless you want to spend hundreds of thousands of dollars…and when you reach it, it’s just frozen ice for hundreds of kms around ….no ‘pole’…just ice.

Nobody lives at the North Pole. This is what the North Pole looked like when the BBC’s Top Gear team and their guides visited:
It’s just a patch of frozen ocean.
Lots of people live in the Arctic Circle, however. There are even some sizeable cities such as Tromsø, Norway; Rovaniemi, Finland; and Fairbanks, Alaska, USA.
The most northern city is Longyearbyen, Norway, though ‘city’ is stretching it. It has a population of around 2000 and is located at 78 degrees north:

Not exactly a bustling place to live.
Oddly, quite a lot of people live at the South Pole, though none of them permanently. The United States’ Amundsen-Scott South Pole Station has a summer population of around 200 and a winter population of 50:
If you mean the geographic North Pole, it is a very specific point on Earth, 90° N latitude.
Since it is a point, it doesn’t have a “center.”
At the point of the North Pole, the Arctic Ocean is 17,811′ deep. In winter it is covered in sea ice, but it may even be open water in summer.
Any flags or signs at the North Pole will drift with the ice and become inaccurate — this does not mean that “the Pole is moving.”

Both polar regions of the earth are cold, primarily because they receive far less solar radiation than the tropics and mid-latitudes do. At either pole the sun never rises more than 23.5 degrees above the horizon and both locations experience six months with no direct sunlight. Moreover, most of the sunlight that does shine on the polar regions is reflected by the bright white surface.
Even though the North Pole and South Pole are “polar opposites,” they both get the same amount of sunlight. But the South Pole is a lot colder than the North Pole. Why? Well, the Poles are polar opposites in othe

Even though the North Pole and South Pole are “polar opposites,” they both get the same amount of sunlight. But the South Pole is a lot colder than the North Pole. Why? Well, the Poles are polar opposites in other ways too.
What makes the South Pole so much colder than the North Pole is that it sits on top of a very thick ice sheet, which itself sits on a continent. The surface of the ice sheet at the South Pole is more than 9,000 feet in elevation--more than a mile and a half above sea level. Antarctica is by far the highest continent on the earth. In comparison, the North Pole rests in the middle of the Arctic Ocean, where the surface of floating ice rides only a foot or so above the surrounding sea.The Arctic Ocean also acts as an effective heat reservoir, warming the cold atmosphere in the winter and drawing heat from the atmosphere in the summer.
The Arctic is ocean surrounded by land. The Antarctic is land surrounded by ocean.
The ocean under the Arctic ice is cold, but still warmer than the ice! So the ocean warms the air a bit.
Antarctica is dry—and high. Under the ice and snow is land, not ocean. And it’s got mountains. The average elevation of Antarctica is about 7,500 feet (2.3 km). And the higher you go, the colder it gets.

Yes, it is very real!
This should give you a good start in your own research on this very interesting subject. Go dig, you are your own best teacher. Bonus. You get your answers immediately.
Because there's no land underneath the ice, only sea, unlike Antarctica where there is land. Glaciers need land to slide down!

But, there is a MAGNETIC set of poles which are NOT permanently placed. They change in accord with the magnetic activity of the semi-fluid magma within the core and have been known even to reverse in the past - not within our lifetimes, nor is it a sudden change, thankfully. The last reversal was the Laschamp event, which they estimate occurred between 41,560 and 41,050 years ago and lasted less than 1000 years. So, are we due? In fact, probably, and we may even now be in the process for all we know. We’ll have some inkling when we ACTUALLY NOTICE that our magnetic compasses are beginning to deviate from what have been Normal Magnetic North and South readings - a few thousand years from now. But, actually noticing this deviation is the issue. It will be so small and slow from day to day.
From the true North Pole all direction point south.
The Magnetic North Pole is currently situated 106 nautical miles south of the true North Pole
Edit: I think this was intended to be a clever little trick question. Since the end of a magnet that is marked ’N’ will point to the North Magnetic Pole, and since opposites magnetic poles attract, the North Pole is actually a south pole. So clever.
Of course in the Southern Hemisphere a compass will be more influenced by the South Magnetic Pole, which is not even on the Antarctic continent but in the Southern Ocean 1544 nuatical miles from the True Sou

The North Pole is at the top of globes and maps, and north of every human being on Earth.
The North Pole isn't moving laterally. It IS rotating one turn (as seen with celestial objects) once every 24 hours.
I believe that you are conflating the North Pole with the North magnetic pole, which is actually moving. That fact has been known for a couple hundred years. Best guess that I've heard so far is that the Earth’s magnetic poles are going to flip to the opposite pole. Possibly soon, because the magnetic North pole’s movement has been accelerating for around 100 years.

Geographical North and South are names of conventions, that is they are north and south because we say that they are, and by conventions, we can change what direction north and south are.

There's some strange movement at the top of the globe right now. The north magnetic pole, which has been used for navigation for centuries, is shifting east - and it's shifting fast. Experts who map these magnetic fields are rushing to keep up as it heads away from Canada and towards Siberia. They've just announced they'll have to update the location of magnetic north a year ahead of schedule. To explain what's happening, Alexandra Witze of the scientific journal Nature joins us now. Hi there.
Ice, and ocean.
Ice, and ocean.
We scientists call it Precession and Nutation. It’s not really a “problem” but I see an amusing result. At MOST times, one of the major Nutations causes the ACTUAL position of the “North Pole” is around 900 feet away from the location where Explorers decide to plant their flags. Several decades ago, I considered trying to establish a “research team” to go up there and ACTUALLY plant a flag at the location that was actually true AT THAT HOUR ON THAT SPECIFIC DAY. (And maybe share a bottle of wine!)
If there was an actual “pole” at the North Pole.. you know, a steel cylinder painted with alternating red and white helical stripes.. that pole would be standing veetically, so it would simultaneously point up and down.
But, there is no actual monument installed at the “North Pole”.. that’s just a name for a place where the rotational axis of Earth (itself a theoretical line around which the Earth spins) intersects the surface of Earth (a surface which is actually underwater at that location).

I’m not sure what you’ve been told. There’s no land there… just two million square kilometers of ice. Also there are no airports, no habitation, no amenities, and very little prospect of sustainable living.
But anyone who wants to and can afford the specialist travel arrangements can go there. They would need to take with them everything they need for their stay, and this would mean food, drink, warm clothing, shelter and probably a way to protect against inquisitive polar bears.
Yes, the south pole is the coldest place on earth. The poles receive much less sunlight; the sun never rises above 23 degrees in the sky. And for half of the year, there's no sun at all.
The north pole is pretty cold; it averages around -30F. But the South Pole is colder, around -60F.
The reason is the same as why Seattle is fairly temperate, even though it's at the same latitude as International Falls, the coldest place on the continental US. It's right next to the Pacific Ocean. Water gains and loses heat fairly slowly, so it acts as a giant heat reservoir, keeping it about the same temperatur

Water gains and loses heat fairly slowly, so it acts as a giant heat reservoir, keeping it about the same temperature all year. The wind blowing east will be moderated by that.
Antarctica is also made colder by being very mountainous. Mountains are cold because the atmosphere is thinner; the atmosphere, like water, moderates the temperature.
Antarctica is a land mass, which gains and loses heat comparatively quickly. (Ever been in a desert? They may be really hot during the day, but get quite chilly at night.) The North Pole is really just a lot of water; it's just frozen at the top. Dig down, or wait for the climate to get just a bit warmer, and that ice can all melt.
The North Pole is really a location in the Arctic Ocean. There isn’t anything physically there that you can recognize it by. The location is occupied by floating ice that moves around.
Even if you figured out exactly where the North Pole was and put something on the ice to mark it’s location, the next day your marker would no longer be at the North Pole.
The North Pole is defined geographically as one of the two fixed “surface” points around which the Earth spins. As for determining when one arrives there…
How would one even know or prove that they’re even standing on the North Pole? Well, in 2018 with a GPS. In 1908, with a chronometer, a sextant and a bunch of complicated calculations. north-pole-controversy-first-person-reach
Of course “there” really means standing atop (or, perhaps, flying over or cruising under) the ice floe which happens to reside at that spot for the moment. Since sea ice drifts, that is inherently a transitory state of a

Of course “there” really means standing atop (or, perhaps, flying over or cruising under) the ice floe which happens to reside at that spot for the moment. Since sea ice drifts, that is inherently a transitory state of affairs.
Even if one considers the seabed as the Pole some mutability is involved. As noted by both Isaac Newton and Leonhard Euler (who came up with a numeric prediction) the Earth, as a non-uniform spinning object would undergo nutation…that is, swaying of its rotation axis. This was confirmed and is now termed the Chandler wobble. However it amounts to a mere change of 30 feet over a period of 433 days!
The real truth? Antarctica is real.
Answering: What’s the real truth about Antarctica and flat earth theory?
Antarctica is a continent at the south pole of the planet Earth. It is not quite round and it is almost entirely covered in ice. It’s a real place. People have been there. My cousin has been there. A former co-worker has been there. NASA did not try to stop either of them from going there.
Did I mention Antarctica is real?
If so, then that is the real truth.

Yes. It's just outside Santa's workshop. ;)
Obviously, the pole at the North Pole can't be permanent, because it's on ice, and in the summer, the ice melts and drifts and the pole would move off the correct spot. So it's not a permanent pole, but they put one there every year.

The North pole is the North Pole. The south Pole is the South Pole.
The North Magnetic Pole is the North Magnetic Pole and the South Magnetic Pole is the South Magnetic Pole. Make no mistake about those FACTS.
However the fact that the North Magnetic end of a compass needle or any swinging magnet points North shows us that the North Magnetic Pole is of a South polarity.
The important thing here is to not confuse the Direction of North/South with the polarity of North/South.
