On April 19, local time, the World Meteorological Organization released the report "The State of the Global Climate in 2020".

The report pointed out that the extreme weather in 2020 and the new crown pneumonia epidemic have caused a double blow to millions of people. The economic recession related to the epidemic has failed to suppress the driving factors and accelerating impact of climate change.

　　The "State of the Global Climate in 2020" report records climate system indicators, including greenhouse gas concentrations, rising land and ocean temperatures, sea level rise, melting ice and glacier retreat, and extreme weather.

The report also highlights the impact on socio-economic development, migration and displacement, food security, and terrestrial and marine ecosystems.

　　The report pointed out that despite the La Niña incident that has a cooling effect, 2020 is still one of the three warmest years on record.

The global average temperature is about 1.2 degrees Celsius higher than the pre-industrial (1850-1900) level.

The six years since 2015 are the warmest on record, and the period from 2011 to 2020 is the warmest decade on record.

　　Talas, Secretary-General of the World Meteorological Organization, said: "It has been 28 years since the World Meteorological Organization issued its first report on the state of the climate in 1993. Our understanding and computing power have been improved, but the basic information has not changed. Now we have more than 28 years of data. These data show significant increases in land and ocean temperatures and other changes, such as sea level rise, sea ice and glaciers Melting and changes in precipitation patterns. This highlights the robustness of climate science based on the physical laws that govern the behavior of the climate system."

　　At the press conference held that day, WMO Secretary-General Taras and UN Secretary-General Guterres jointly released the flagship report of the World Meteorological Organization.

Guterres said: "This report shows that we have no time to waste. The climate is changing, and its impact has brought too much to human beings and the planet. This year is the year of action. All countries need to commit to 2050. To achieve net zero emissions by 2021, it is necessary to submit its ambitious national climate plan before the United Nations Climate Change Conference in 2021, and jointly reduce global emissions by 45% from 2010 levels by 2030. All countries need to take immediate action to protect mankind from the climate The catastrophic impact of change."

　　According to the report, the 2020 new crown pneumonia epidemic has added new adverse effects to weather, climate and water-related disasters, and has a wide-ranging comprehensive impact on human health and well-being.

Restrictions on the movement of people, economic recession, and damage to the agricultural sector have all exacerbated the impact of extreme weather and climate events on the entire food supply chain, increased food insecurity and hindered the delivery of humanitarian assistance.

The epidemic has also disrupted weather observations and complicated disaster risk reduction efforts.

　　The report also shed light on how climate change can bring risks to the achievement of many sustainable development goals through a cascading chain of interconnected events.

These aspects will promote the current inequality to increase or worsen.

In addition, there may be feedback loops that foreshadow a vicious cycle of climate change that will continue.

　　The report "The State of the Global Climate in 2020" was published before the leaders’ climate summit from April 22 to 23, and updated the interim report previously released.
