What do you know about Greenland?

Greenland has a cold polar climate, and only the southwest is slightly warmer due to the influence of the Gulf Stream. There is a persistent layer of cold air over the icy interior of the island, and low-pressure air masses often move from west to east above the cold air, causing the weather to change rapidly, sometimes with sunshine and sometimes with wind and snow. The average temperature in winter (January) is minus 6℃ in the south and minus 35℃ in the north. In summer (July), the average temperature along the southwest coast is 7°C, and in the far north, the average summer temperature is 3.6°C. Among them, the coldest central plateau region has an average monthly temperature of minus 43°C and an absolute minimum temperature of minus 70°C. It is the second "cold pole" on earth after Antarctica. The average annual precipitation decreases from 1900 mm in the south to about 50 mm in the north. Greenland has a severe cold climate and vast amounts of ice and snow. According to measurements by scientists, the total volume of ice on the island reaches 2,600 trillion cubic meters. If all this ice melts, all sea levels on the earth will rise by 6.5 meters.

Greenland relies entirely on thick ice to protrude high above the sea level. If the ice layer were removed, Greenland would not have such a towering appearance, but would only be like an oval plate fixed on the sea. Because there is only snow and no rain all year round, Greenland is a kingdom of ice and snow, except for a few areas such as the southwest coast where there is no permafrost and only a few trees and green spaces. 85% of the island's surface is covered with glaciers and heavy icebergs. Greenland ice cubes contain a lot of bubbles and make a continuous popping sound when put into water, making them a very good cold drink agent. People call it "Ten Thousand Years of Ice". This kind of ice is both clean and pure. Drinking a sip of "Ten Thousand Years Ice" on a hot summer day is a rare treat. Greenland is rich in "ten thousand-year ice", with an average ice thickness of 2,300 meters, second only to the huge modern continental glaciers in Antarctica.
