(Deutsche Welle website in Chinese) UN Secretary General Guterres delivered a speech on the state of the earth at Columbia University in New York on December 2 and mentioned the serious threat posed by climate change in his speech. He said: “The state of the earth has been destroyed and mankind is waging a war against nature. Nature will gather strength and anger to fight.”
In his speech, Guterres mentioned the report “The state of the global climate in 2020” issued by the World Meteorological Organization (WMO) on the 2nd. He reiterated that they were the hottest years on record, and the decrease in ice, the melting of permafrost, large-scale climate fires and unprecedented hurricanes are just some of the consequences of climate change.
Guterres said that humanity must stop deforestation, because this is one of the main reasons that exacerbate climate change. He said, “Humans must stop plundering nature’s resources and let human-caused damage to nature begin to heal.”
Guterres said climate policy has failed to meet the challenge. He noted that carbon emissions in 2020 are 60% higher than in 1990. He said: “We are moving towards the goal of increasing the global average temperature from 3 to 5 degrees Celsius by 2100.”
However, Guterres believes the world can see hope in 2021 and emphasized that a truly global alliance must now be established to achieve carbon neutrality. To achieve this goal, the world must achieve net zero greenhouse gas emissions by 2050. Guterres noted that more than 110 countries have committed to achieving carbon neutrality on this day, and the total carbon emissions of these countries represent 65% of global emissions.
He said the core of achieving this goal is setting a carbon price, phasing out funding and subsidies for fossil fuels, and encouraging the use and development of renewable energy. Guterres emphasized the need for the international community to launch a global climate movement. He said, “We don’t have a vaccine for the planet.”
The hottest in the last 6 years.
A report released by the World Meteorological Organization on the 2nd confirmed that, compared to the same period last, 2020 is by far the second hottest year. The annual climate record details the phenomena caused by global warming: frequent severe droughts, unprecedented hurricanes, retreating sea ice, heavy rains and floods in Asia and Africa, and widespread oceanic heat waves.
The most important part of the global climate report is confirming that global warming in 2020 is accelerating. Although 2016 is still the hottest year on record in the world so far, the year opened with a very strong Nativity phenomenon, during which the warmer ocean will raise the global temperature.
Four years later, although the anti-Santo Infante phenomenon made the weather colder as of September this year, these maximum temperatures continued. The global average temperature from January to October 2020 is approximately 1.2 degrees Celsius higher than the reference temperature from 1850 to 1900.
The World Meteorological Organization report stated: “2020 will be one of the three warmest years on record. The past six years are likely to be the six warmest years on record.”
The most important part of the global climate report is confirming that global warming in 2020 is accelerating.
In the Arctic region of Siberia, the temperature in 2020 is more than 5 degrees Celsius above the average temperature. The temperature in Verkhoyansk in late June reached 38 degrees Celsius, temporarily making it the highest known temperature anywhere north of the Arctic Circle. Petteri Taalas, Secretary General of the World Meteorological Organization, said: “We have seen extreme new temperatures appear on land, oceans and the Arctic. Forest fires have gripped Siberia in Australia, the west coast of the United States and America. from the South, causing smog to spread around the world. Inner loop. “
Greenhouse gases continue to rise
The report also indicated that the lockdown policy implemented to curb the spread of the new corona epidemic only resulted in a temporary reduction in carbon emissions in 2020. Therefore, the rapid growth of carbon emissions in 2019 will be “really indistinguishable” from a slowdown. The concentration of greenhouse gases produced by burning fossil fuels reached a new record in 2019, and the increase in carbon dioxide, methane and carbon monoxide was also greater than the increase in the previous two years.
The report says: “Real-time data from specific regions shows that the levels of carbon dioxide, methane and carbon monoxide will continue to rise in 20202.” These increases are in line with the proposed special report on global warming by rapidly reducing carbon emissions to increase global temperature. The control appears after 1.5 degrees Celsius.
Global warming keeps increasing
The World Meteorological Organization report also wrote that the reason for the faster rise in sea level is the intensification of melting ice in Greenland and Antarctica. At the same time, more than 80% of the ocean area has experienced at least one ocean heat wave in 2020. Among them, 43% of the oceans have experienced ocean heat waves classified as “strong”. 2019 is also the year with the highest ocean heat content in history.
In 2020, heavy rains and widespread flooding affected most of Africa and Asia. In the North Atlantic, 30 named storms appeared, setting a record for the number of named storms in history. In addition, most of the interior of South America will be affected by a severe drought in 2020. The most affected areas include northern Argentina, Paraguay and the western border areas of Brazil.
The report said: “Climate and meteorological events have triggered a large number of population movements, severely affecting vulnerable groups in the movement, including the Pacific and Central America.”
