Atmospheric CO2 levels rise sharply despite Covid-19 lockdowns

Scientists find coronavirus crisis has had little impact on overall concentration trend

Carbon dioxide levels in the atmosphere have risen strongly to a new peak this year, despite the impact of the global effects of the coronavirus crisis.

The concentration of CO2 in the atmosphere reached 417.2 parts per million in May, 2.4ppm higher than the peak of 414.8ppm in 2019, according to readings from the Mauna Loa observatory in the US.

Without worldwide lockdowns intended to slow the spread of Covid-19, the rise might have reached 2.8ppm, according to Ralph Keeling, a professor at the Scripps Institution of Oceanography. He said it was likely they had played a small role, but that the difference was too small to show up against other factors causing year-to-year fluctuations.
