Web9 mrt. 2024 · Methane is a potent greenhouse gas, so the study of its natural and anthropogenic biogeochemical sources and sinks is of enormous interest. For many years, scientists considered methane to be produced only by single-celled microbes called Archaea, upon decomposition of organic matter in the absence of oxygen (anaerobic). WebThe increase during 2024 was 15.3 ppb. Atmospheric methane levels averaged 1895.7 ppb during 2024, or around 162 percent greater than pre-industrial levels. From NOAA’s observations, scientists estimate global methane emissions in 2024 are 15 percent higher than the 1984-2006 period.
