2020 officially was one of the hottest years ever recorded, a sign of uninterrupted global warming, according to a small review that scientists published around the world last week.
Tropical history comes after a year filled with natural disasters: hurricanes, tornadoes, and wildfires.
“This is a clear indication that global awareness of climate change as a result of human behavior is now as powerful as the environment,” Petteri Taalas, secretary-general of the World Meteorological Organization, said in a statement.
The study does not agree that 2020 was the hottest year on record. A NASA report released Thursday found that 2020 hit 2016 as the hottest year, neatly constructing the notes. Another analysis, published Thursday written by the National Oceanic and Atmospheric Administration, the last 2020 was the second near 2016. And last week, the European Union’s Copernicus Climate Change Service confirmed 2020 arrested by 2016 as a very hot year.
His conclusions are slightly different because research teams use different methods to compare the global warming model based on the heat that is visible for thousands of seasons.
The 2020 global warming record is the latest in a number of years to come to the fore.
“The last seven years have been the hottest seven years on record,” says Lesley Ott, a NASA researcher. As a result, regardless of where the year falls, “the volatility of the most recent years has become more pronounced,” he said.
In all of these studies, “the gap between 2020 and 2016 is small compared to the uncertainty of the data,” Zeke Hausfather, a meteorologist with independent research team Berkeley Earth, told BuzzFeed News via email. “That’s why it’s one of the warmest bindings.”
2020 was marked by intense year-round temperatures, rampant until the end of natural cold, La Niña.
“The special heat of 2020 is even an event in La Niña, which is cold for a while,” Taalas said.
Climate change led to a major warming record in 2020.
Siberia experienced a heat wave for months and the Arctic town of Verkhoyansk was extremely hot, reaching 100 Fahrenheit on June 20. “This would not have been possible without climate change,” the team said. he concludes.
2020 was the hottest year in Europe, with a temperature of 1.6 degrees Celsius between 1981 and 2010, according to Copernicus. 2019 previously had this record, when the temperature was considered to be 0.4 degrees Celsius than immediately.
Last year he showed up again The most common hurricane in the Atlantic Ocean, as well as history a deadly wildfire in the western US. The result was that the US met with it many billions of disasters in 2020. The year began again with some of forest fires in Australian history. In addition, carbon dioxide emissions continued to rise in the atmosphere, hitting 413 million shares last May.
Meanwhile, the plague brought with it the financial crisis that has plagued it US exports lose about 10.3% in 2020, according to an initial review by the research organization Rhodium Group, part of a major global emissions trends last year. But a slight reduction in emissions will not be enough to end global warming – which will require long-term cutting.
“The amount of heat we are seeing is due to human greenhouse gases,” Ott said.
