WebAtmospheric methane (CH4) increased from ˘900ppb (parts per billion, or nanomoles per mole of dry air) in 1900 to ˘1800ppb in 2010 at a rate unprecedented in any observational records. However, the contributions of the various methane sources and sinks to the CH4 in-crease are poorly understood. Here we use initial emissions Webphotosynthesis.
