The planet we live on, Earth, is a tiny composition in this enormous universe. It features diversity ranging from highly variable temperature and pressure ranges, as well as various types of ecosystems. One such notable feature of the earth is the polar ice caps. There are three main important features: Antarctic ice at the South Pole, Arctic ice at the North Pole, and Greenland to the north between North America and Europe. Antarctica makes up about 90% of the world's ice (and 70% of its fresh water). It is covered in ice 2,133 meters (7,000 feet) thick. If all Antarctic ice melted, sea levels worldwide would rise by about 61 meters (200 feet). Arctic ice is not that thick in comparison and mostly floats in the Arctic Ocean. Greenland, on the other hand, would add another 7 meters (20 feet) to the oceans if it melted because Greenland is closer to the equator than Antarctica, temperatures there are higher, so the ice is more likely to melt . Scientists from the Universities of London and Edinburgh say ice loss in Antarctica and Greenland together contribute about 12% to sea level rise. The melting of these huge bodies of ice can have a significant impact on global climate change, and conversely, these climate changes also affect the melting of ice bodies. It is a bidirectional process and the causes are mostly of anthropogenic origin. Recent studies based on NASA satellite monitoring reveal that melting ice at both poles has been responsible for a fifth of global sea level rise since 1992 (11 mm). Antarctica and Greenland contribute three times more ice to sea levels today than they did 20 years ago. Even though the Greenland Ice Sheet is only about... half the size of the map... the land has always changed from time to time, ever since it was formed, and it is one of the most unpredictable processes. Although it is a natural process, nowadays the anthropic contribution is also taken into account. According to studies, although the Earth should be in a cooling phase during this period, it is clear from the melting of the polar ice caps that the Earth is warming. The polar ecosystem is therefore going through a phase of dynamism due mainly to external disturbances such as the increase in temperature and the thermal expansion of the ocean. Therefore the need of the hour is to be aware of the changes taking place in the ecosystem and unite to prevent or adapt to the changing conditions. Only then can an ecosystem function healthily with its diversity of species and good interaction between them and their environment.
