Global average temperature may rise by 7 degrees Celsius in 2100, scientists call for reduction of carbon emissions

According to the "European Times" report, on September 17, local time, French scientists issued a warning that the greenhouse effect problem was more serious than previously thought.
The worst estimate is that by 2100, the global average temperature will increase by 7 degrees Celsius.
Scientists call on people to take action to reduce carbon dioxide emissions.
According to reports, the UN Climate Panel will release a new report on climate change in 2021, which will be the sixth report since 1990.
More than one hundred researchers and engineers from the French National Scientific Research Center, the Atomic Energy Commission and the Meteorological Agency have jointly studied two climate models to supplement this report and provide a reference for the Intergovernmental Panel on Climate Change.
According to the research of French scientists, the most pessimistic situation is based on the rapid economic growth and the extensive use of fossil fuels, which will cause the global average temperature to increase by 6.
5 degrees Celsius to 7 degrees Celsius in 2100.
The 2014 report of the Intergovernmental Panel on Climate Change predicts that the temperature will be 4.
8 degrees Celsius higher than in the pre-industrial era.
What does this mean for human society? In France, the constant heat is a good example.
The 2003 heat wave killed 15,000 people in France.
After 2050, intense heat will be a normal phenomenon.
　　This climate model will also have some consequences: long-lasting and extensive droughts; since 2070, the Garonne River in France will dry up for several months; serious problems in agricultural production; forest fires More and more phenomena and so on.
　　Scientists have also given an optimistic assumption that is based on full international cooperation and listing sustainable development as a key task, which will make the global average temperature rise below 2 degrees Celsius.
This requires people to reduce carbon dioxide emissions as soon as possible.
　　In 2015, the Paris Agreement was adopted at the Paris Climate Change Conference, aiming to control the global average temperature rise of this century within 2 degrees Celsius, and control the global temperature rise within 1.
5 degrees Celsius above the level of the pre-industrial period.
　　The French National Scientific Research Center, the French Meteorological Agency, and the French Atomic Energy Commission unanimously emphasized: "By the end of this century, the average temperature on the earth depends entirely on the climate policy we adopt from now on and throughout the 21st century.
" 　　Other countries Some climate models have also been announced, which will also be used for reference to the Intergovernmental Panel on Climate Change.
These models also emphasize that the temperature will rise substantially.
　　These scientific studies have enabled scientists to more accurately predict some of the consequences of climate warming.
For example, there will be heat waves in Eastern Europe; glaciers in the Arctic will melt and may even disappear by the end of the century in the summer; the Indian Ocean will have more There are more and more hurricane phenomena.
