Carbon dioxide, or CO2, measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory in Hawaii peaked for 2022 at 421 parts per million in May, “pushing the atmosphere further into territory ...

CO2 is measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory on the Big Island, and this year, it peaked at 421 parts per million. This hasn’t been seen for millions of years.

Why is the Mauna Loa Observatory so important? ... CO2 makes up just 0.04% of the atmosphere, which is a lot less than oxygen, for instance, at 21%. That may not sound like much.

At Mauna Loa, the NOAA observatory has a long history of measuring atmospheric CO2. Volcanic CO2 is removed from their long-term atmospheric dataset, though that removed data can in turn be used ...

This 2019 photo provided by NOAA shows the Mauna Loa Atmospheric Baseline Observatory, high atop Hawaii’s largest mountain in order to sample well-mixed background air free of local pollution ...
