Shaping a sustainable future.

🔬 CO2 concentration, measured in parts per million (ppm), is a key indicator of global warming. A record level of 425 ppm, as observed in May 2023, means that 0.0425% of the air is composed of CO2.

Historically stable at 285 ppm, this concentration has been rising significantly since the 1850s. Measured daily since the 1960s by the Mauna Loa Observatory in Hawaii, the ppm level provides a valuable historical reference for understanding climate change.
