A study of ground level atmospheric ethane concentrations from twenty four stations around the world in the sample period 2005-2015 does not show evidence that ethane emissions from shale gas production have reversed a falling trend in atmospheric ethane in the Northern Hemisphere. The data suggest that natural variability is the more likely cause of the observed changes in atmospheric ethane worldwide.
