2020 bubbling hot. Global warming is the culprit.
According to some analyses released by scientists around the world last week, 2020 has officially become the hottest year on record, marking that global warming has not abated.
After a year of climate catastrophe, a heat record was produced: historic heat waves, hurricanes and wildfires.
The Secretary-General of the World Meteorological Organization, Petteri Taalas, said in a statement: “This clearly shows that the global signals generated by man-made climate change are now as powerful as natural forces.”
The analysis is inconsistent as to whether 2020 is the hottest year in history. The National Aeronautics and Space Administration (NASA) found in a report released on Thursday that 2020 almost surpassed 2016, becoming the hottest year ever. Effectively record.Another analysis Published on Thursday The conclusion drawn by the National Oceano and Atmospheric Administration is that 2020 is second only to 2016.And last week, the European Union’s Copernicus Climate Change Service (Copernicus Climate Change Service) Tied with 2016 As the warmest year.
Because the research team used various techniques to piece together global temperature images based on temperature observations from thousands of weather stations, the conclusions they reached were slightly different.
The heat record for 2020 is only the latest record of the heat increase for several consecutive years.
NASA researcher Lesley Ott said: “The past 7 years have been the hottest on record.” Therefore, no matter where each year falls, “the continuity of recent years has been The warmest since records,” she said.
For all these analyses, “the difference between 2020 and 2016 is less than the uncertainty in the record,” Zeke Hausfather, a climate scientist at Berkeley Earth, an independent research organization, told BuzzFeed News via email. “So this is actually the warmest tie.”
Most of 2020 will be hot, but it is only over due to the natural cooling phenomenon of La Niña.
Taras said: “Despite the La Niña incident, the high temperature in 2020 will still bring a temporary cooling effect.”
Climate change drives other major high temperature records in 2020.
Siberia has experienced a month-long heat wave. The Arctic town of Verkhoyansk hit its hottest day on record, reaching 100 degrees Fahrenheit on June 20. “If there is no climate change caused by human factors, this event is practically impossible.” to sum up.
Copernicus’ analysis shows that 2020 is the hottest year on record in Europe, 1.6 degrees Celsius higher than the average temperature from 1981 to 2010. This record was maintained before 2019, and the observed temperature was 0.4 degrees Celsius higher than the same period.
Last year also marked The busiest known hurricane season in the AtlanticAnd history A series of wildfires in the western United States.As a result, the U.S. experienced Billion dollar disaster In 2020. The worst forest fire in Australian history. In addition, the amount of carbon dioxide in the atmosphere continues to rise, reaching a new high of 413 parts per million in May last year.
At the same time, the pandemic triggered an economic shock, leading to U.S. emissions are expected to fall by 10.3% According to the preliminary analysis of the research organization Rhodium Group, by 2020 The greater trend of global emissions decline last year. However, short-term emissions reductions are not enough to curb the trend of world warming-this will require long-term emissions reductions.
Otter said: “Most of the warming we see is due to human emissions of greenhouse gases.”
