Carbon dioxide levels in the atmosphere reach the highest level in 63 years


According to data released by the Scripps Institute of Ocean Sciences and the National Oceanic and Atmospheric Administration (NOAA) in the USA, carbon dioxide concentrations reached 419 parts per million (PPM) last month.

The researchers pointed out that this is the highest figure recorded during the 63-year history of carbon dioxide measurements, and reminded that this level was 417 PPM in May last year.

Pointing out that the main control of atmospheric carbon dioxide is related to fossil fuel emissions, NOAA official Ralph Keeling said, “We still have a long way to go to stop the rise, as more carbon dioxide accumulates in the atmosphere every year.” used the expression.

“We are moving towards a point we never want to reach”

Noting that they expect the concentration to exceed 420 PPM in 2021, Keeling warned, “We are moving towards a point we never want to reach.”

Thanks to the closures within the scope of measures taken worldwide due to the new type of coronavirus (Kovid-19) epidemic and the decrease in vehicle use, carbon emissions decreased by 7 percent last year, which was the highest annual decrease since the Second World War.

While experts are certain that emissions will rise again in 2021, they drew attention to the need to reduce emissions by up to 2 billion tons per year in the next 10 years, pursuant to the Paris Climate Agreement.
