At the end of 2020, the end of 2020 marks the end of the warmest decade on record, according to the World Meteorological Organization. This year is still likely to be one of the three hottest years on record, even as hot as 2016.
World Meteorological Organization: 2020 may be one of the hottest years on record
The World Meteorological Organization points out that although La Nina phenomenon has a cooling effect on the global climate as a whole, 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 Nina is expected to peak in December or next January.
World Meteorological Organization Secretary General Talas said record breaking high temperature years usually occur during El Nino events, as in 2016. We are now experiencing La Nina phenomenon. It has a cooling effect on global temperature, but it is not enough to stop the temperature rise this year. This year’s high temperature is close to the record level of 2016.
Based on five global temperature databases, the World Meteorological Organization (WMO) will release comprehensive temperature data for 2020 in January next year. This information will be included in the final report of the state of global climate 2020, which will be released in March next year, including climate impacts. According to the interim report of the state of global climate in 2020 issued by the World Meteorological Organization in early December, the data of the first 10 months of this year set 2020 as the year with the second highest temperature so far, second only to 2016 and higher than 2019.
The WMO also said long-term trends are more important than annual temperature rankings. Since the 1980s, every decade has been warmer than the previous one. This trend is likely to continue as greenhouse gas emissions in the atmosphere reach record levels. Carbon dioxide, in particular, will be in the atmosphere for decades, leading to a warmer planet in the future.
