417, Yes. 417
May 2020 hit a record high, 417 parts per million (ppm) carbon dioxide as measured at the Mauna Loa Observatory, which has continually measured CO2 in the atmosphere since 1958.
The reading of 417 ppm is likely the highest it has ever been in the history of humans on Earth. On top of that, it is likely the highest concentration seen on Earth in 3 million years.
