Obviously it wasn't going to last. CO² emissions are skyrocketing.

The World Missions ed carbon dioxide, the gas greenhouse most responsible for global warming, have returned to levels close to those before the pandemic, announced scientists in a new report released Wednesday.

This ann ed ea saw an increase of 4.9% ed missions relative to 2020, similar to the rebound that followed the global financial crisis of 2008, the report said. About 36.4 billion tonnes of carbon dioxide have been released into the atmosphere in the past year, the report estimates.

Carbon dioxide - emitted by burning fossil fuels such as oil, gas and coal - remains in the atmosphere about a century before dissipating.

"We expected to rebound when the e world economy would be back close to normal," said Rob Jackson, professor at Stanford University and Chair of the Global Carbon Project, an academic group that produces annual estimates of carbon emissions. “Park your car for a year and it's the same polluting vehicle when you restart it. The same is true when economic activity picks up, and so do emissions, ”he said.

The last ye a r ry, containments li e s coronavirus had an effect"Even extreme" on the e carbon emissions, causing a drop é standard 17% worldwide during the height confinement periods beginning of April 2020 - levels that had not been observed since 2006.

The m e t e orologue from Penn State University, Michael Mann, who has not participated ed to the report, ad ed clared to USA TODAY that he was not surprised that emissions have rebounded to such a degree. “It would have been crazy to expect anything else. What the carbon emissions figures show is that the curves depicting emissions (correcting the short-term response to COVID-19) have broadly flattened now. This is the good news.

"The bad news, it's that it is not enough. We need to start doing them go down. It is to lis that must serve the COP26. "

The new estimates for carbon arrive in the middle of the great summit COP26 climate in Glasgow, NS pod, w here the countries that sign ed the Paris Agreement on the 2015 climate discuss efforts to achieve the objective of the agreement to keep global warming well below 2 degrees Celsius above préindustratifs levels, and preferably below 1.5 degrees Celsius.

"Despite the trag é é die of pand ed crumb Covid in 2020, the strength and nature of the rebound ed fossil CO2 emissions show that the world has not done much to focus on a green recovery "said Glen Peters, director of research at CICERO Center for international climate research in Norway, who helped prepare the report.

The ed carbon dioxide emissions are on track to increase in all countries and regions of the world r e e e this year compared to 2020."We thought that the world coal use peaked in 2014, but we are dangerously close to that value again this year , ”Jackson said in a statement from Stanford University.

For example, ed carbon emissions in India are expected to reach 2.7 billion tons, up 3% compared to 2019 and 12.6% compared to 2020. As in the US, emissions in Europe are slightly below 2019 levels at 2.8 billion tonnes.

The rest of the world as a whole, which includes the world international transport, is expected to produce 14.7 billion tons of CO2 this year, down slightly compared to 2019 due to reductions related to the pandemic in shipping and 'aviation.

China, the largest world producer ed over the last 15 ed è res ann es, had the distinction of having increased its emissions even during the pandemic. The country's carbon pollution is expected to reach 11.1 billion tonnes this year, up 6% from 2019 and 4% from 2020 - in part thanks to post COVID-19 recovery incentives that have stimulated industrial production by relying heavily on coal.

"The rapid recovery of mission é é as the economies recover from the pand ed crumb enhances e n e necessity of a global action imm e diate against climate change," said Professor Pierre Friedlingstein of University of Exeter in the UK, which led the report.
