Hawaii CO2 levels hit record high, exceeding 430 ppm

Atmospheric carbon dioxide concentrations reached a record high, exceeding 430 parts per million at the Mauna Loa Observatory in Hawaii, according to NOAA and Scripps Institution of Oceanography. This marks another concerning milestone in climate change. Scientists reported a May monthly average of over 430 ppm, a significant increase from the previous year. The Mauna Loa Observatory, a key site for monitoring, has tracked rising CO2 levels since measurements began in 1958. The ongoing rise in CO2, a major greenhouse gas, contributes to global warming and extreme weather events. The data collected at Mauna Loa is crucial for climate research and informs international efforts to address climate change.
