Höchstwerte von Kohlendioxid und Methan am Sonnblick gemessen

The concentrations of carbon dioxide and methane measured on the Sonnblick in April 2023 reached the highest value since measurements began.

Carbon dioxide and methane are the strongest drivers of human-caused climate change. At the Sonnblick Observatory (3100 m above sea level) in April 2023 the monthly average concentration of carbon dioxide was 425.3 ppm (parts per million = part per million) and of methane 2.014 ppm.

These are the highest values ​​since measurements began and confirm the continuously increasing trend of these two most important greenhouse gases in Austria and worldwide.
