（2025·河北·模拟预测）Greenland is the world’s largest island and a self-governed territory of Denmark. About 57,000 people live there, mainly along its coasts. Most of Greenland lies north of the Arctic Circle, under thick sheets of ice. The island plays a large part in the weather experienced by billions of people every day and in climate changes around the planet, experts say.
Greenland has huge amounts of oil and natural gas below the ice and valuable elements known as rare earth minerals needed in communication technologies, including phones. Most of these resources are trapped under Greenland’s ice. However, warming temperatures have increased melting on the island. As more ice melts, some of these resources may become easier to reach. Other countries are becoming interested in Greenland because China is currently the supplier of over half of the world's rare earth minerals.
From 1992 to 2020, Greenland lost an average of 169 billion metric tons of ice each year, with losses reaching 444 billion metric tons in 2019. A well-known expert said that melting from Greenland will be a central issue through the 21st century. That is because melting ice adds to rising sea levels. He noted that the amount of melting will likely increase in the future.
Greenland also serves as the engine for an important ocean current that influences Earth’s climate in many ways, including storm activity. The current is called the Atlantic Meridional Overturning Circulation, or AMOC． The current is slowing down because more fresh water from Greenland's melting ice is entering the ocean. A shutdown of the current could lead to long-term freezes in Europe and parts of North America.
As more ice melts, Greenland is also changing colour from the white of ice to the blue and green of water and land. These darker colours hold more heat from the sun and can increase the speed of warming.
Greenland lies in between northern Canada, northern Europe, and Russia. That area may become more valuable to countries if melting in the Arctic Ocean continues to increase and more ships pass through the area.
