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.
Carbon dioxide tends to peak each year in late May, when the impacts of the northern hemisphere spring have yet to take effect, so the month’s data is compared from year to year. Measurements have been taken continuously at the remote Mauna Loa observatory in Hawaii since 1958, providing vital information for climate scientists.

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.

Carbon dioxide tends to peak each year in late May, when the impacts of the northern hemisphere spring have yet to take effect, so the month’s data is compared from year to year. Measurements have been taken continuously at the remote Mauna Loa observatory in Hawaii since 1958, providing vital information for climate scientists.
