Atmospheric methane concentrations are rising faster since 2007


An international group of researchers led by LSCE (CEA-CNRS-UVSQ) has published a thorough budget of methane sources and sinks1  over the last decade in the Earth System Science Data (ESSD) journal, complemented by en editorial in Environmental Research Letters, both to be published on December 12 2016. These studies show that none of the scenarios of the 5th IPCC2  report correspond to the observed increase in methane concentrations. The published results highlight the contribution of methane on the climate change.
