Explanation:
The glaciers contained in the Arctic are essential for cooling the earth's climate, which is why Arctic conditions are so important in determining the earth's climate changes.
These glaciers reflect about 80% of the sunlight in the northern hemisphere, and can cool the region's climate. If Arctic glaciers melt, most of the sun's rays will be absorbed by the ocean, increase the temperature and increase the melting of the glaciers.
As a result, the entire ecosystem will be damaged.
