Here, we report carbon and hydrogen isotopic measurements of atmospheric methane in archived air samples collected 1977?1998, and modeling of these with more contemporary data to infer changes in methane sources over the period 1984?2009. We present strong evidence that methane emissions from fossil fuel sectors were approximately constant in the 1980s and 1990s but increased significantly between 2000 and 2009. This finding challenges recent conclusions based on atmospheric ethane that fugitive fossil fuel emissions fell during much of this period. Emissions from other anthropogenic sources also increased, but were partially offset by reductions in wetland and fire emissions.
