According to the data released by the World Meteorological Organization, 2011-2020 is the hottest decade since the Industrial Revolution, and the hottest of these years is 2020.
According to the report of the Indian Express on the 3rd, the report of the World Meteorological Organization collected meteorological data for the first 10 months of 2020. Analysis shows that the average temperature in 2020 is 1.2 °C higher than that of the Industrial Revolution (1850-1990).
Since 2015, global temperatures have been rising, and 2020 has become the hottest year in 10 years. Petri Tarastan, Secretary-General of the World Meteorological Organization, said that there is still a 20% chance that global temperature will continue to rise in the next four years, 1.5°C higher than during the Industrial Revolution, which is the threshold set by the Paris Agreement for global warming.
CNN said that although the La Niña phenomenon in the Pacific region has a cooling effect, the heat brought by greenhouse gases to the atmosphere has greatly offset its effect, causing the abnormal heat in 2020.
Extreme weather has occurred frequently this year. Reports show that the number of tropical cyclones worldwide in 2020 is far above average, and has caused many casualties and damage in Nicaragua, the United States, the Philippines and other places.
The most obvious change occurred in northern Asia, especially in Siberia, and the temperature was 5 °C higher than in previous years.
