10 indicators of
​global warming
Covers the basic science and all  the indicators
Global warming is much more than the global average surface temperature increase, and there are various climate change indexes that combine various global warming/climate change indicators, that better reflect planetary warming.

​​One of the best is IGBP's climate change index that combines the global warming indicators in one graph and is educational.

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. The highest atmospheric methane of 2000 ppb is at Lac La Biche on the Southern edge of Canada's carbon rich wetlands (800,000 methane maximum is 800ppb). 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,”

20 Sept 2015 Washington Post (with the 2015 temperature trend) While 2014 was a record surface temperature year (jus), 2015 will be a record year by a wide margin
