According to the report's statistics, the global average temperature in 2021 (January-September) is about 1.09 degrees Celsius higher than that of 1850 to 1900, and is currently ranked as the sixth or seventh warmest year on record globally by the World Meteorological Organization. The data show that global greenhouse gas concentrations have reached a new high in 2020, and this increase continues in 2021.
The oceans are warming to a new record
Due to global warming, the ocean is first facing a serious warming problem, and the temperature of the upper 2,000 meters of the ocean has reached a new record. At the same time, the oceans are acidifying due to rising concentrations of greenhouse gases, as they absorb about 23 percent of the carbon dioxide emitted by humans each year. This has also led to a decline in the ocean's ability to absorb carbon dioxide, exacerbating the problem of atmospheric greenhouse gas concentrations.
Sea ice extent at record low, melting rate doubled
The loss of glaciers and ice sheets is no better. The report warns that the extent of sea ice across the Arctic reached a record low in the first half of July; The rate at which North American glaciers are melting almost doubled between 2015 and 2019 compared to the early 2000s. Average annual sea level rise of 4.4 mm between 2013 and 2021 is twice as fast as between 1993 and 2002.
Worsening climate conditions have led to more extreme weather events around the world
Since the beginning of this year, people in many countries around the world have also witnessed the deterioration of the climate and the occasional extreme weather.
Early this year, heavy snow and low temperature weather affected the United States, especially the southwest Texas was severely affected. Many people were killed and millions of homes and businesses lost power.
From June to July this year, many places in western North America and the Mediterranean region experienced high temperatures of more than 40 degrees Celsius, and the highest temperature in some areas exceeded 50 degrees Celsius. Extreme heat has sparked major forest fires in California, Turkey and Greece.
In March, rain continued to fall along Australia's east coast, causing the worst flooding in New South Wales in 50 years. In July, extreme rainfall also hit many countries in Western Europe, causing floods and heavy casualties and property losses.
In May, the United States, Brazil, Paraguay, Argentina and other countries were all hit by severe drought.
In March, Mongolia suffered from strong sandstorms and snowstorms, which also affected many places in northern China.
Countries have actively consulted and China is committed to fulfilling its commitments
Faced with the impact of extreme weather and climate change, countries around the world are actively consulting and exploring solutions. Some participants at the climate conference said China has shown strong resolve in tackling climate change and is committed to fulfilling its commitments.
Sharma, President of COP26: I would like to tell you that in the last few months, we have made significant progress in stopping investment in coal.
Patricia Espinosa, Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC) : I am in close contact with the G20 countries, including China, especially China. I see a very strong commitment to meet their commitments, including carbon peak by 2030.
