The rise happened despite an estimated 7% reduction in global emissions due to the pandemic, according to the National Oceanic and Atmospheric Administration.
NOAA and Scripps Institution of Oceanography feature similar findings. Following quote from Scripps was most interesting and distressing:
"It took over 200 years for levels to increase by 25%, but now just over 30 years later, levels are at a 50% increase," the institution said. Should the current trends continue, it predicts that CO2 levels will be twice as high as pre-industrial levels in about 55 years.
