An animation released recently by NASA shows that Arctic sea ice has decreased significantly in the past 35 years. If this trend continues, the impact on climate will not be reversed and the global environment will be severely affected. Maybe in a few decades, the Arctic sea ice will disappear completely. These data mean that in the near future, the Arctic Ocean will become an ice free ocean in some seasons.

In some areas, sea ice will form and disappear with seasonal changes, but there is always a certain proportion of sea ice in the Arctic circle that can not melt all the year round, that is, the so-called “perennial ice”. In the first week of January 1984, there were 3.1 million square kilometers of sea ice in the Arctic Ocean that had existed for more than four years. By contrast, in the first week of January 2019, the area of multi-year ice in the region has shrunk to 116000 square kilometers.

This means that the area of multi-year ice in the Arctic circle has drastically decreased by 95% in just 35 years. Today, from the northernmost tip of Alaska, there is no sea ice within 700 kilometers. At this time in previous years, sea ice can be seen not far from the shore. This fully shows how much Arctic sea ice has changed.

These changes will bring serious environmental and cultural consequences, and will pose a major threat to the safety and life of residents in the Arctic circle. The hunting behavior of indigenous people will also be affected, because they can’t walk on the ice, and polar bears and walruses and other creatures can’t move on the ice.

In some parts of the Arctic, coastal erosion is becoming more and more serious. Because part of the coast is made up of sediment, it has been “glued” together by permafrost. Today, not only is permafrost affected by rising temperature and water temperature, but the reduction of sea ice also makes these coastal areas more vulnerable to waves. The coastline of parts of Alaska can be retreated several meters a year.

Climate change is a certainty. It is not a problem left for future generations to solve decades later, but it is imminent. Those who deny climate change often regard seasonal changes such as ice sheet melting as evidence that “climate change is not man-made, but God’s will”. But this is not the case. It can be seen from the change trend of ice over the years that although there are ups and downs caused by natural factors in the curve.

In the video released by NASA this time, many people may be shocked by the sharp reduction of the Arctic ice sheet, but the response of scientists is quite calm. After all, climate change is an absolute fact. The Arctic is just playing a leading role, where the changes are first observed and most prominent.
