If the temperature rises by 1.5℃, what may happen to the earth?

In response to global climate change, countries adopted and signed the Paris Agreement. Its main goal is to control the global average temperature rise since this century. In the range of 2 degrees Celsius, the global temperature rise is within the range of 65438 0.5 degrees Celsius of pre-industrialization.

Through 6,000 scientific publications issued after the Paris Agreement of 20 15, this new report is obtained: in view of the current carbon emissions, the global temperature has broken the boundary of 1.5℃, and it may reach 1.5℃ at some time from 2030 to 2052, and the continuous temperature is 3℃ or 4℃.

You may not know the global temperature rise 1.5℃, but the following data can tell you that the global temperature has risen from 1.5℃.

Temperature rise 1.5℃ will lead to cold weather on land, and more polar storms will appear in high altitude areas of East Asia and North America.

A temperature rise of 1.5℃ will lead to a sea level rise of 26-77 cm, and millions of people living in coastal areas will be affected.

The temperature rise of 1.5℃ will damage 13% of the global land and increase the risks of many insects, plants and animals.

A rise of1.5 c will cause the Arctic to experience one or two free summers every 10 year.

Temperature rise 1.5℃ will reduce many coral reefs by 70% to 90%.

It must be said that this will be a problem for many earth ecosystems and many people in the coming decades. According to the report of the United Nations organization, with the global temperature rising 1.5℃, the extreme temperature in some mid-latitude areas in the world will be 2 1 century, and NO in the Arctic will increase. 70% to 80% of the existing coral reefs will disappear after being frozen for a long time.

Ordinary people may think that the global temperature rise 1.5℃ or 2℃ has little impact, but it has a significant impact on nature and human beings. Huang Lei of China National Climate Center said that if the temperature rises by 65,438 0.5℃ in the future, the global sea level will rise by 0.26 m to 0.77 m ... Don't underestimate this rising height, which is enough to drown many countries.

In addition, global temperature rise does not mean worldwide unity. According to experts, due to the great difference in heat between land and ocean, land warming is greater than that of ocean, and medium and land warming at high latitudes is greater than that at low latitudes. Land. The extreme temperature change of land far exceeds the global average surface temperature change, such as the extreme low temperature in high latitudes.

This is why the country is committed to controlling the world temperature, because every extra warming will have a far-reaching impact on the world.
