If the temperature rises by 1.5℃, what changes may happen to the earth?
In order to cope with global climate change, countries adopted and signed the Paris Agreement. Its main goal is to control the global average temperature rise since this century. Within 2 degrees Celsius, the global temperature rise is within 1.5 degrees Celsius of the previous industrialization.
through 6, scientific publications released after the Paris agreement in 215, this new report was obtained: given the current carbon emissions, the global temperature broke the boundary of 1.5 C, which may reach 1.5 C at some time from 23 to 252, and the temperature is going to be 3 C or 4 C..
you may not be very clear about the global temperature increase of 1.5 c. The following data can tell you that the global temperature has increased from 1.5 C.
A temperature increase of 1.5°C will lead to cooler weather on the land. At high altitude, there will be more polar storms in East Asia and North America.
a temperature increase of 1.5°C will cause the sea level to rise by 26-77 cm, and millions of people living in coastal areas will be affected.
a temperature increase of p>1.5°C will damage 13% of the global land and increase the risks of many insects, plants and animals.
a temperature increase of 1.5°C will cause the arctic to experience one or two free summers every 1 years.
A temperature increase of 1.5℃ will cause many coral reefs to decrease by 7% to 9%.
it has to be said that this will be a problem for many earth ecosystems and many people in the coming decades. The report, from the United Nations, shows that with the global temperature rising by 1.5°C, the extreme temperature in some mid-latitude regions in the world will increase in the 21st century, and NO in the Arctic will increase. When the ice is long, 7% to 8% of the existing coral reefs will disappear.
ordinary people may believe that the global temperature will increase by 1.5°C or 2 c, which has no great effect, but it will have a significant impact on nature and human beings. Huang Lei from China's National Climate Center said that if the future temperature rises by 1.5°C, the global level will increase by .26 m to .77 m.. Don't underestimate this rising height, which is enough to drown many countries.
In addition, global temperature rise does not mean uniformity in the world. According to experts, because the heat between land and ocean is very different, land warming is greater than that of ocean, and media and land warming at high latitudes are 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 our country is committed to controlling the world temperature, because every extra temperature rise will have a profound impact on the world.
