The ice sheet covers approximately 80% of Greenland making it the number one trademark of the land.
The Grenland Ice Sheet is a remarkable natural formation, shaped over millions of years through the gradual accumulation and compaction of snow, gases, dust, and water. While the landscape may appear static - a vast, frozen expanse unchanged for millennia - the ice sheet is, in fact, dynamic: a living, evolving system.
With an average thickness of 2-3 kilometers, the immense weight of the ice exerts continuous pressure causing it to flow outward toward the sea. As a result, this so-called "inland ice" also extends to much of Greenland's coastline. Here, glaciers connected to the ice sheet calve into the ocean, creating the iconic icebergs that drift along Greenland's shores.
Beyond its impressive scale, the ice sheet functions as a natural climate archive - almost like a time machine. Each year, new layers of snow settle on the surface, gradually compressing into ice and stacking over thousands of years. These layers trap information about the temperature and atmospheric conditions at the time they formed.
By drilling deep into the ice and extracting core samples, scientists can date each layer and analyze the trapped particles, gases, and isotopes. This method has provided us with detailed records of Greenland's climate history - reaching back more than 250,000 years.
