What is the concept of 1℃? What does the rising temperature of the earth mean to human beings?

With the arrival of winter, the northern hemisphere has entered the coldest time of the year. At this time, many people hope that the temperature will rise a little. Of course, if the temperature rises by one degree, many people may not feel too big, but for the earth, if the temperature really rises by one degree, the impact is enormous. I think many people have heard of the greenhouse effect. With the development of our industrial revolution, scientists have found that in the past few decades, our global average temperature has been rising year by year. With the rise of global temperature, it has brought a serious consequence, that is, the melting of polar glaciers will lead to the rise of sea level, and the most serious areas are Southeast Asia and southern Europe. Otherwise, the global temperature rise will not happen in a short time. Although sometimes there will be some extremely abnormal weather, overall, the global temperature rise is a relatively slow process. Scientists also predict that at the end of this century, the temperature of the earth may rise by 65,438 0.5 degrees Celsius, a large amount of land will be submerged by the ocean, and a large amount of fresh water resources stored in the polar regions will also melt into the ocean.

Meteorologists have set up a model. When the temperature rises by one degree, the sea level will rise by 2.3 meters, which will cause great trauma to the ecological environment and local economic development in coastal areas. Moreover, with the rise of sea level, it brings a more serious problem, that is, the area where people can live together will become smaller and smaller, especially some animals, who have lived in a relatively stable environment for millions of years, but because of human activities, their living environment is getting smaller and smaller, or even no living environment. Especially the creatures living in polar regions, because their previous environment is relatively simple, they can't adapt to the changeable environment brought by the rising temperature, which will lead to the extinction of penguins and polar bears in large numbers. So if the global temperature rises by one degree, it will be a disaster for many species.
