• Geopolitics of the Arctic
• Northern Sea Route

What it concludes

• Greenland is the largest and most fascinating island in the world, more than three times larger than France and part of the Kingdom of Denmark for over 300 years.
• Two-thirds of Greenland stretches high into the Arctic Circle, making it much colder than average, though the Gulf Stream brings milder weather to much of the island.
• Approximately 80 percent of Greenland's surface is covered by an ancient ice sheet containing roughly 2,850,000 cubic kilometers of frozen ice.
• Scientific studies revealed that Greenland was once nearly completely ice-free and vegetated at least once in the past million years.
• Greenland's ice sheet is currently melting at an accelerated rate of about 200 billion metric tons per year, which could raise global sea levels by around 30 centimeters by the end of this century.
• If the entire Greenland ice sheet were to melt completely, it would contribute a volume of water to the world's oceans greater than the entirety of the Gulf of Mexico, resulting in a catastrophic global sea level rise of approximately 7 meters and flooding major coastal cities worldwide.
