World Co2 Ppm 2025 Graph. Midcentury CO2 levels might be as high as they've ever been in 50 million years The Global Monitoring Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites [Conway, 1994] CO2 Is The Number to Watch When the trend for atmospheric CO2 trend begins to falter and fall, we can expect global average temperature to follow.

The mole fraction is expressed as parts per million (ppm) The graphs show monthly mean carbon dioxide measured at Mauna Loa Observatory, Hawaii 427.09 ppm CO2 in atmosphere in February 2025 at the Mauna Loa Observatory
Learn about climate change & global warming. Monthly mean atmospheric carbon dioxide (CO₂) concentrations reached a record high of 426.91 parts per million (ppm) in June 2024.
