How much has the Arctic climate changed compared with the past?

Affected by global warming, the temperature in the Arctic is gradually rising and the sea ice area is greatly reduced. In the past, the winter in the Arctic was long and cold, and some areas were covered with ice and snow all year round, which was also where polar bears lived. With the global temperature rising, the warming rate in the Arctic region is now more than twice as fast as that in other regions, resulting in a significant reduction in the habitat area of organisms in this region, which is likely to lead to a decrease in species. Moreover, the pollution in the Arctic is quite serious, and these pollutants will be eaten by animals in this area by mistake, leading to the accumulation of pollutants in animals.

With the expansion of human production area year by year, environmental pollution is serious, and global warming cannot be separated from the influence of human activities. While global warming causes the temperature to rise, the warming extent in the Arctic region is far greater than that in other parts of the world, which can reach twice or even more than the average global warming level. This phenomenon directly leads to the melting of Arctic sea ice. The data report shows that the sea ice area in the Arctic has decreased by 40% compared with the last century, and long-term climate warming may even lead to the appearance of the Arctic? No ice? Phenomenon.

The melting of Arctic glaciers will lead to the accelerated rise of global sea level. As the climate warms and glaciers melt, there will be more and more extreme weather. As the main habitat of the Arctic, polar bears have to spend more time on land because of the climate change in the Arctic, which greatly reduces their habitat area. In the long run, the number of polar bears will gradually decrease, which is the adverse impact of Arctic climate change on Arctic creatures.

At the moment of global warming, not only the climate in the Arctic has changed dramatically, but also extreme weather caused by climate change frequently appears around the world. These extreme weather phenomena not only affect human production activities, but also endanger human life safety. Therefore, protecting the environment is an eternal theme, and human beings should not wantonly destroy the natural environment on which we live. After all, there is only one earth.
