China News Service, January 15th. According to a report from the Chinese website of the United States, several major temperature databases were updated on the 14th local time, and 2020 and 2016 were tied together as the hottest years on record.

Among them, four databases believe that 2020 will be slightly cooler than 2016.

With a slight gap, 2019 became the third hottest year in history.

　　Data show that the atmospheric carbon dioxide concentration that causes global warming has reached a high level that has never been seen in at least the past 3 million years.

　　Since the 19th century, the seven hottest years have occurred in the past decade. The temperature in 2020 has been about 1.2 degrees Celsius higher than the temperature in the 19th century.

　　"This is the global average." said Ahira Sánchez-Lugo, a physicist at the National Environmental Information Center of the National Oceanic and Atmospheric Administration (NOAA). "Some areas are warming faster."

　　She added that 1 degree Celsius may sound rare, but "a small change in the average global temperature may cause a major change in extreme weather. We are already seeing this."

Data map: On July 28, 2020, local time, in Dobricevez Village, Czech Republic, the local people played in the river to relieve the heat.

　　As expected, since the 1960s, every decade has been hotter than the previous decade.

　　The record high temperature in 2016 was due to the temporary effects of El Niño.

The situation in 2020 is different.

Not only will there be no irregular warming trend in 2020, but also the La Niña phenomenon, which is the opposite of El Niño, will appear in August.

　　From January to November in 2020, each month ranks among the top four hottest months in history, and December is the eighth hottest December in history, helping to lower the annual average temperature.

　　According to another study released this week, ocean temperatures will also hit a new high in 2020.

　　Due to the huge amount of human carbon dioxide emissions, although economic activity has stagnated due to the new crown virus pandemic in 2020, the related emission reductions still have little effect.

The International Energy Agency estimates that global carbon dioxide emissions in 2020 will only drop by 8% compared to 2019, which is equivalent to the level in 2010.

Data from research firm Rhodium Group shows that in the United States, carbon dioxide emissions have fallen by 10.3%.

The Met Office predicts that by 2021, carbon dioxide emissions in the atmosphere will exceed 50% of pre-industrial levels for the first time.

　　NOAA has already predicted that there is a 99.6% chance that 2021 will enter the hottest 10 years in history.

However, due to the La Niña phenomenon, there is only a 7.4% chance of 2021, which will exceed the highest temperature records in 2020 and 2016.
