Greenland is officially recognized as the world's largest island by Guinness World Records. Its land area is approximately 2,175,600 square kilometers, far surpassing other large islands such as Papua or Borneo.
However, Greenland is not categorized as a continent.
Many people ask why Australia isn't considered the largest island. The answer is because Australia is generally classified as a continent, not an island.
With that exception, Greenland automatically takes the top spot as the largest island on the planet.

Greenland's Strategic Geographical Location
Greenland is located in the northern hemisphere, between the North Atlantic Ocean and the Arctic Ocean. The island lies east of Baffin Bay and close to the North Pole.
Politically, Greenland is an autonomous territory under the Kingdom of Denmark. This means Greenland has the authority to regulate its own internal affairs, while foreign affairs and defense remain under Denmark.
Despite its enormous size, Greenland's population is relatively small, only about 55,000. The majority of residents live in coastal areas, as the central part of the island is nearly uninhabitable due to the thick ice sheet.

One of Greenland's most distinctive features is the perpetual ice sheet that covers most of its territory. It's estimated that over 80% of Greenland's landmass is covered in ice, with ice reaching 3 kilometers in thickness in some spots.
This ice sheet is more than just an ordinary iceberg; it represents one of the world's largest reserves of fresh water. This is where Greenland plays a crucial role in the global climate system.
However, along the coast, the scenery offers stark contrasts. You'll find deep fjords, steep cliffs, icy mountains, and dramatic and beautiful coastlines.

Extreme Climate Full of Unique Phenomena
Most of Greenland lies north of the Arctic Circle, so it experiences long, dark winters. Temperatures can drop very low, especially inland.
During summer, conditions are slightly milder, especially in coastal areas. Average temperatures can reach around 9 degrees Celsius.
Although it is still relatively cold, this period allows for outdoor activities and more active community life.
Natural phenomena such as the midnight sun and the aurora borealis are also a special attraction for Greenland.

Greenland's Role in Climate Change Issues
The Greenland ice sheet is a major focus of climate change research. If this ice were to melt on a large scale, global sea levels could rise significantly, impacting many coastal areas worldwide.
Therefore, Greenland is often used as an important indicator for monitoring the impacts of global warming. What happens on the world's largest island can provide insights into the future of Earth's climate.
Conclusion
So, Greenland, as the largest island in the world, not only excels in terms of area, but also plays an important role globally.
From its perpetual ice sheet, its unique Inuit culture, to its influence on climate change, Greenland holds many fascinating stories.
