: Experts in climate change said that the social prohibition and quarantine policies implemented by the countries of the world to confront the Corona epidemic contributed to reducing the emission of gases in the period between January and April 2020, by 17% in their daily rate.
Lord of beneficial harm
The experts - who were able for the first time to measure the size of greenhouse gases in line with the quarantine - added that if the situation continues as it is until next June, the decrease in the accumulation of greenhouse gases in the atmosphere will reach 4% compared to the first half of a year 2019, and the percentage will reach 7% by the end of this year, although it is unlikely.
These experts explained - in the study, which is the first of its kind and was published in the "Nature Climate Change" magazine on May 19 this year - that they developed a smart model that enabled them to measure the rates of this decline by sectors.
They found that the transportation sector contributed 43% to the decline of these gases, followed by the industrial sector by 25%, electricity generation by 19%, and finally the aviation sector by 10%.
"The quarantine has reduced the global consumption of energy responsible for greenhouse gas emissions in the transportation, electricity generation, and other sectors," said researcher Quinn Lockerry of the University of East Anglia in Britain, in a statement via e-mail to Al Jazeera Net.
Concrete evidence for decision-makers,
Lockeri added that "despite this, quarantine is not a solution to face climate change, as its contribution to low greenhouse gases is not permanent." Occasion".
"To confront climate change, we need bold global policies that depend on moving from fossil energies to renewable energies, as shown in the study," she said.
The experts relied in this study on data provided by the governments of 69 countries that contribute 97% of the greenhouse gases that they pay in the atmosphere, and at the top of the list is the United States and China.
Internationally and Arably,
according to the details of the study, there are two countries in which greenhouse gases decreased by 40%, namely Luxembourg and New Zealand.
As for Arabs, Morocco ranked first with 29.5%, followed by Saudi Arabia with 28.9%, then Algeria ranked third with 27.1%.
"If the Corona epidemic constitutes a human tragedy, it has allowed us to observe climate change with a look," said Glan Peter, who is the director of scientific research at the International Center for Research in the Environment and Climate in the Norwegian city of Oslo - in a statement included in the press statement accompanying the study issued by the University of East Anglia. New".
He added that "quarantine policies were not intended to confront this phenomenon, but the new data produced by this epidemic will help us in the future to plan more effective climate policies."
