The state of global climate planetary emergency is definite because of the combination of today's climate state (recorded by science) and the science of climate change commitment -locked in heating.
The renewed sustained post 2007 atmospheric methane increase, attributed to feedback process warming wetland peat, is particularly ominous. Sept 2013 carbon sources and sinks research indicates increased methane from record coal mining and from warming wetlands.
