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.
10 Sept 2015 James Hansen “We’ve now got an emergency,” “Amplifying impacts” and feedback loops will accelerate the changes" “It will happen faster than you think,
”It is therefore imperative to stop using coal, oil and gas as energy sources now. We’ve already burned as much as we can afford"
“We’ve only felt the warming for half of the gases that are up there,”
