2020 was a hot year. Global warming is to blame


2020 has officially been one of the hottest years in the history of global warming, according to a series of analyzes published by scientists around the world over the past week.

The heat record comes a year after climate disasters, from historic heat waves, storms and fires.

“This is a clear indication that man-made global climate change signals are now as powerful as the forces of nature,” said Peter Thalas, secretary general of the World Meteorological Organization.

Analysts disagree on whether 2020 was the hottest year ever. NASA’s report released on Thursday shows that 2020 is smoothly surpassing 2016 as the warmest year ever. effectively linking the post, Another analysis was published on Thursday The National Oceanic and Atmospheric Administration concluded that 2020 was the second year in 2016. And last week, the European Union’s Copernicus Climate Change Service decided on 2020. 2016 as the warmest year.

The findings differ slightly as research teams use different methods to merge the global temperature picture based on temperature views of thousands of weather stations.

The heat record of 2020 is the last in recent years to receive more heat.

“The past seven years have been the hottest seven years,” said NASA researcher Leslie Ott. So, no matter where the individual years fall, “the consistency of recent years is the warmest, very, very clear,” he said.

For all these analyzes, the difference between “2020 and 2016” is smaller than the recorded uncertainty. “So it’s an effective tie for the hottest.”

2020 was marked by bee heat for most of the year, only to be dimmed at the end by the phenomenon of natural cooling, La Niña.

“The exceptional heat of 2020 despite the La Nina event, which has a temporary cooling effect,” Thalass said.

Climate change broke other major heat records in 2020.

Siberia had its heat wave for several months, reaching its hottest day in the Arctic city of Verkhoyansk, reaching 100 degrees Fahrenheit on June 20. “This event would not have been possible without human climate change,” he said. concluded,

According to Copernicus, 2020 was the warmest year in Europe, with temperatures averaging 1.6 degrees above average between 1981 and 2010. 2019 previously held this record, where the observed temperature was 0.4 degrees higher than the same period.

Last year was also celebrated The most popular hurricane season in the Atlantic Ocean, as he’s historically A series of devastating forest fires in the western United StatesThe result was that the United States tried its best Most of the $ 1 billion disasters In 2020. The year also started in some parts The worst fires in Australian historyMoreover, the level of carbon dioxide continued to rise in the atmosphere, hitting a new maximum of 413 parts per million in May last year.

At the same time, the epidemic caused an economic shock US emissions to fall by about 10.3% In 2020, according to a preliminary analysis by the research organization Rhodium Group, a Last year, there was a greater trend of declining emissions around the world“But a short fall in emissions will not be enough to curb global warming, which will require long-term cuts in emissions.”

“The vast majority of the warming we see is due to human emissions of greenhouse gases,” Ot said.
