Abstract

Methane: masked intruder Changes in atmospheric methane levels over the past twenty years are well documented, but the causes of these changes remain uncertain. Bousquet et al. use inverse (top-down) modelling to quantify variations in methane emissions from different sources between 1983 and 2004. They find that a decrease in the growth rate of atmospheric methane during the 1990s was caused by a decrease in anthropogenic emissions, but that anthropogenic emissions have increased again since 1999. To date, this trend has been masked by a coincident decrease in wetland emissions, but it is possible that it will cause total methane levels to rise again in the near future.
