Antarctica: myths and reality about cold and warmth on the icy continent

When it comes to Antarctica, the first thing that comes to mind is endless icy deserts, piercing winds and temperatures at which even the alcohol in a thermometer freezes. But is everything so clear? Is the planet's southernmost continent really perpetually cold, or are there places where you can warm up? In this article we will figure out why Antarctica is considered the coldest place on Earth, where record low temperatures are recorded, and whether there are zones with a relatively “warm” climate here.

Spoiler: even in Antarctica there are areas where the temperature rises above zero in the summer, and on some islands mosses and lichens even grow. But to understand how this is possible, you need to delve into the geography, climatology and unique natural processes that make this continent so different from all others. Are you ready to travel through the icy expanses with an excursion into science?

Why is it so cold in Antarctica: 5 key reasons

Antarctica is not just a “cold continent”, but a real climate anomaly. Here is the absolute record for the lowest temperature on Earth: −89,2 °C (Vostok station, 1983). But why are there such extreme conditions here? It’s all about a combination of factors that turn Antarctica into the natural “freezer” of the planet.

Firstly, geographical location. The continent is located around the South Pole, where the sun's rays fall at a minimal angle, and the polar night lasts up to six months. Secondly, altitude: average height of Antarctica - approx. 2,500 meters, and in the center of the continent the ice sheet rises to 4,000 meters. The higher, the colder - this principle works here too.

• 🌍 Polar position: The sun never rises high above the horizon, and in winter it does not rise at all.
• ❄️ Ice Shield: Ice thickness reaches 4.8 km - it reflects up to 90% solar radiation.
• 🌬️ Katabatic winds: Cold air flows from higher elevations at speeds up to 320 km/h.
• 🌊 Southern Ocean isolation: The Westerly Winds block warm waters from the tropics.
• ☁️ Dry air: Antarctica is the largest desert in the world and receives less rainfall than the Sahara.

Another paradox: despite the fact that Antarctica is covered with ice, it is technically desert. Everything falls here 50–100 mm of precipitation per year - in the form of snow that never melts. That is why the air here is not just cold, but also extremely dry, which enhances the feeling of frost.

The coldest places in Antarctica: records and their “owners”

If you think that −30 °C is already extreme, then in Antarctica such temperatures are considered almost “warm”. There are several points on the continent where the cold reaches extreme levels. The leader among them is Vostok station is a Russian scientific base located in the very center of East Antarctica. It is here in 1983 the absolute minimum was recorded: −89,2 °C.

But this is not the limit! Satellite data NASA showed that in some areas of East Antarctica temperatures can drop to −98 °C. These zones are located in high mountain areas, where cold air stagnates in natural “traps”. Interestingly, such extreme values ​​are recorded only on clear winter nights, when heat escapes into space.

Place	Record temperature	When fixed	Features
Vostok station	−89,2 °C	July 21, 1983	The lowest temperature on the planet recorded by a weather station
House Argus Plateau	−98 °C	2010 (satellite data)	Coldest place on Earth according to data NASA
Amundsen-Scott Station	−82,8 °C	June 23, 1982	American base at the South Pole
Lake Vostok	−80 °C (surface)	Regular measurements	Subglacial lake with a unique ecosystem

By the way, people work at Vostok station all year round. How do they survive in such conditions? The clothing here is made up of multi-layer heated suits, and the accommodation modules are heated by diesel generators. Even going outside without special equipment means getting frostbite in a matter of minutes.

⚠️ Attention! At temperatures below −60 °C, the metal becomes brittle and the fuel freezes. For example, at the Vostok station, diesel fuel is heated before use, otherwise the engines will not start.

Are there warm places in Antarctica? Antarctic "Crimea"

Yes, you heard right - there are relatively warm zones in Antarctica! We're talking about Antarctic Peninsula - the northernmost part of the continent, which stretches towards South America. Here the climate is milder: in summer the temperature can rise to +5…+10 °C, and in winter it rarely drops below −20 °C.

For example, on Argentine base "Esperanza" in 2020 a record was recorded: +18,3 °C - the highest temperature in the history of observations of Antarctica! This is due to the fact that the peninsula is washed by warm currents, and the mountains block cold winds from the mainland. There are even ice-free areas here - the so-called Antarctic oases, where in the summer the snow melts and streams appear.

• 🌿 South Shetland Islands: In summer temperatures up to +10 °C, mosses and lichens grow.
• 🏝️ Oasis Banger: Ice-free all year round, there are lakes with fresh water.
• 🐧 Coast of the Scotia Sea: Penguins and petrels nest here.
• 🌡️ Bellingshausen Base (Russia): Average summer temperature +1…+3 °C.

But don’t be fooled: even in these “warm” zones, the climate remains harsh. The winds here blow at a speed 100–150 km/h, and the weather can change several times a day. For example, at the Akademik Vernadsky base (Ukraine) there are often situations when in the morning it is +5 °C, and in the evening -10 °C with hurricane winds.

What is a foehn in Antarctica?

A foehn is a warm, dry wind that blows down from the mountains and can raise the temperature by 20–30 °C in a few hours. In Antarctica, it occurs on the slopes of the Transantarctic Mountains and sometimes leads to sudden melting of snow.

How people survive in the Antarctic cold: technology and life hacks

Working in Antarctica is not only scientific research, but also a daily struggle for survival. There are no hospitals, shops or emergency services here: if something goes wrong, help may only arrive in a few days (or even weeks). Therefore, every detail matters - from clothing to psychological preparation.

Polar explorers' clothing consists of several layers:

1. Thermal underwear (synthetic or merino wool).

2. Insulation (down jacket or fleece).

3. Windproof suit (often heated).

4. Special shoes with insulated sole and spikes.

A face mask, glasses with UV protection and gloves with touch inserts (to operate the equipment without removing them) are also required.

Housing at stations usually consists of modular houses with enhanced thermal insulation. For example, at Vostok station the walls are thick 1.5 meters, and the windows are triple-glazed and heated. The heating works around the clock, but even then the temperature inside is maintained no higher +20 °C (so that there is no sharp contrast with the street).

⚠️ Attention! In Antarctica, it is prohibited to use open fire outside special premises. Due to the extremely dry air, even a small spark can cause a fire that cannot be extinguished due to lack of water.

Global warming and Antarctica: is it getting warmer there?

Over the past decades, climate scientists have been sounding the alarm: Antarctica is losing ice at a record pace. According to data NASA, with 1992 to 2017 the continent lost about 3 trillion tons of ice, which led to a rise in sea levels by 7.6 mm. But does this mean that Antarctica is getting warmer?

The answer is ambiguous. On the one hand, Antarctic Peninsula - one of the fastest warming zones on the planet: in recent years 50 years the temperature here has increased by 3 °C. On the other hand, in East Antarctica Record frosts are still being recorded, and the ice sheet is even growing slightly due to increased snowfall.

• 📈 West Antarctica: Melting at an accelerated pace, glaciers are sliding into the sea.
• ❄️ East Antarctica: Stable, but scientists are detecting cracks in the ice shelves.
• 🌊 Larsen Ice Shelf: Split into pieces in 2002 and 2017.
• 🐋 Ecosystem: Adélie penguins are migrating further south due to krill decline.

The biggest danger is ice shelf instability. For example, a glacier Thwaites (the size of Great Britain) is melting at a rate 800 meters per year. If it collapses, sea levels will rise by 65 cm, which threatens coastal cities around the world.

Myths about Antarctica: what is true and what is fiction?

Antarctica is surrounded by many myths - from “forbidden zones” to “underground alien bases”. Let's look at the most popular of them and separate facts from fantasy.

Myth 1: There are areas in Antarctica where access is prohibited. Reality: Indeed, some areas are closed to visitors, but not because of “secret experiments”, but to protect unique ecosystems. For example, Specially Protected Areas (ASPA) - These are penguin nesting sites or scientific sites where you cannot go without permission.

Myth 2: Antarctica has no owner and can be captured. Reality:According Antarctic Treaty (1959), the continent does not belong to any state. Military bases and mining are prohibited here. However, several countries (including Russia, the US and China) have research stations here and lay claim to the sectors in the future.

Myth 3: You can find polar bears in Antarctica. Reality: Polar bears live only in Arctic. In Antarctica, their closest “relatives” are leopard seals and crabeater seals. But there are more penguins here than people - about 20 million individuals!

FAQ: Answers to popular questions about Antarctica

Is it possible for a tourist to visit Antarctica, and how much does it cost?

Yes, but it's very expensive. Average cost of a cruise from Ushuaia (Argentina) - $10 000–$20 000 per person. Tourists visit the Antarctic Peninsula, but disembark only in permitted areas. Flights to the continent (such as Glacier Union Station) cost $30 000–$50 000.

Is it true that there are active volcanoes in Antarctica?

Absolute truth! The most famous - Erebus volcano (height 3,794 m), which erupts almost constantly. There is even a lava lake here - one of only five in the world. There are also subglacial volcanoes on the continent, which can accelerate the melting of ice.

Why is it impossible to bury the dead in Antarctica?

Due to extreme conditions, the bodies do not decompose, but become mummified. According to the rules of the Antarctic Treaty, all the dead must be evacuated from the continent. For example, the body of a researcher Oleg Troitsky (died in 2019 at Bellingshausen station) was taken to Chile for burial.

Is there Internet and mobile communications in Antarctica?

Yes, but very limited. Most stations have satellite Internet (speed 1–5 Mbit/s), but it is only used for work. Calls home are possible via satellite phones (Iridium or Inmarsat). Social networks and streaming services are usually blocked to save traffic.

Is it possible to see the northern lights in Antarctica?

No, it happens here southern aurora (Aurora Australis). It is less famous than the northern one, but no less spectacular. The best time for observation is winter (March–September), when the polar night lasts for several months.
