Mauna Loa volcano in Hawaii is the key to climate research

Almost 70 years ago, in March 1958, Charles David Keeling began to measure carbon dioxide on the Mauna Loa volcano. We owe this work to one of the most well-known representations of the climate problem. Now the place may be threatened.

At an altitude of 3400 metres on the Mauna Loa in Hawaii, an observation station has provided crucial data on climate change for 67 years. Initiated by Charles David Keeling in 1958, its CO2 measurements revealed an alarming increase in the concentration of this gas in the atmosphere. Despite its importance, the station faces threats of closure due to budget cuts. Keeling's work fundamentally transformed our understanding of the human impacts on…
