The Arctic 
The sources of methane feedback emissions are:
​o warming wetlands,
o ​thawing permafrost and
o ​over very long term warmed sea floor methane hydrates.


These regions hold three to four times all the carbon in the atmosphere.

​​​​The loss of all the summer sea ice will increase the rate of Arctic warming 3.5 times (D Lawrence 2008) which will boost the rate of methane emissions from the Arctic.  ​

Since the record sea ice loss of 2007, the ​​atmospheric methane concentration has been increasing and  the scientists say this increase is due to carbon feedback emissions, some of which are coming from the rapidly warming Arctic. 

​​Wetlands and methane hydrate can both respond rapidly to an increase in global warming. Arctic  Methane hydrate has the potential to abruptly release a catastrophic amount of methane to the atmosphere. ​  

Land based permafrost ​​responds slower to warming as the methane is emitted as a result of micro-organisms digesting the thawed organic material.

​However at a certain amount of thawing permafrost thaw becomes self perpetuating - irreversible. This because the microbial activity generates heat indide the thawing permafrost.   
Nothing  makes today's planetary emergency more definite than the rapidly changing state of the Arctic because there are many +ve amplifying feedbacks triggered by Arctic warming. These can cascade as a mighty deadly domino effect (C Duarte 2012)​

​It is well known that the vast expanse of Arctic summer sea ice (and spring-summer snow) have a cooling effect on the region which moderates the climate and weather of the temperate northern hemisphere. This the Arctic summer air conditioner for the entire Northern hemisphere. The loss of the 'albedo' cooling effect will disrupt the climate and increase extreme weather northern latitudes. Research shows this has started already. Drought is projected to increase. Extreme cold could affect some regions at unseasonal times. Without an emergency response now, crop yields of the world's best food producing regions will progressively decline.

Arctic sea ice past ice free tipping point.​​​
The first great Arctic amplifying feedback domino is falling and others are starting. ​
​James Hansen made public statements in 2008 and in 2012 following the two record drops in Arctic Summer sea ice- warning the world had entered a state of planetary emergency. The reason is that, as he said in 2008, the Arctic sea ice had crossed its ice free tipping point in 2007, which is a very large +ve amplifying feedback. This will boost Arctic feedback GHG emissions and the rate of the Greenland ice sheet melt, both being planetary catastrophes.  Tipping point expert Tim Lenton has also said he thinks the Arctic summer sea ice is past tipping the point.

Two Arctic methane science papers prove we have an Arctic warming planetary emergency. ​​In 2013 A Vask's research of Siberian Permafrost caves determined that the vast Siberian permafrost has a tipping point for thawing of only 1.5C and that global climates only slightly warmer than today are sufficient to thaw extensive regions of permafrost. We are absolutely committed to a 1.5 warming due to the ocean heat lag alone.


Less Arctic albedo cooling results in more Arctic
​warming, an amplifying feedback
​called Arctic/polar amplification. ​

​While the Arctic sea ice provides a vast extent of albedo cooling (which is now declining fast) to its September minimum, Far North snow from Spring to mid Summer provides an equally vast expanse of albedo cooling equivalent to the sea ice albedo (M. Flanner 2011). ​​​​​This is also rapidly declining as the snow declines earlier every year.

Arctic & Far North carbon​
​​Arctic perma​frost holds twice the carbon in the atmosphere and subsea floor frozen solid methane gas hydrate holds at least as much carbon as in the atmosphere. All this carbon will be released with too much warming, and that has started already.

The Arctic at the top of the world is at the center of the planetary emergency and the trigger is the rapid loss of Spring-Summer Far North-Arctic snow and ​Summer sea ice.
