WebThe MLO has been measuring atmospheric composition since the 1950s, providing the clearest record of CO 2 concentrations across the 20th and 21st century. To reconstruct long-term CO 2 concentrations, we have to rely on a number of geological and chemical analogues which record changes in atmospheric composition through time. WebMethane (CH4) is a highly reduced C1 compound and long lived atmospheric gas (12±3 years) with high global warming potential i.e., 28-36 times that of CO2 over 100 years. The current (i.e., 2024) atmospheric CH4 level is recorded as ~ 1863 part per billions (ppb). Since 2014, an average annual increase of atmospheric CH4 level measured as ~10 ppb …
