World Meteorological Organization: 2020 may be one of the hottest years on record
At the end of 2020, data from the World Meteorological Organization showed that the end of 2020 marks the end of the warmest decade on record.
This year is still likely to be one of the three hottest years on record, or even comparable to the hottest 2016.
The World Meteorological Organization pointed out that although the La Niña phenomenon generally has a cooling effect on the global climate, it will still be extremely hot in 2020 and affect weather patterns in many parts of the world.
Most models show that the intensity of La Niña is expected to peak in December or January next year.
World Meteorological Organization Secretary-General Taras said that record-breaking high-temperature years usually occur during El Niño events like 2016.
We are now experiencing the La Niña phenomenon, which has a cooling effect on the global temperature, but it is not enough to prevent the temperature from rising this year. The high temperature this year is close to the record level of 2016.
Based on five global temperature databases, the World Meteorological Organization will release 2020 comprehensive temperature data in January next year.
This information will be included in the final report on the State of the Global Climate in 2020 to be released in March next year, including climate impacts.
According to the World Meteorological Organization’s interim report on the State of the Global Climate in 2020 released in early December, the data for the first 10 months of this year has designated 2020 as the year with the second highest temperature so far, second only to 2016 and higher than 2019.
The World Meteorological Organization also stated that long-term trends are more important than annual temperature rankings.
Since the 1980s, each decade has been warmer than the previous decade.
As greenhouse gas emissions in the atmosphere reach record levels, this trend is likely to continue.
Especially carbon dioxide will exist in the atmosphere for decades, which will cause the earth to become warmer in the future.
