The Arctic methane potential is a global warming carbon bomb (as has been
Previous estimates of Arctic carbon have doubled making the Arctic the site of 40% of all the planet's carbon.
Latest research finds the Arctic is already a substantial source of methane to the
Arctic methane emissions are increasing as the Arctic warms several times faster than the rest of our planet.
The more the temperature increases and the longer the Arctic warms the more
The most catastrophically dangerous methane source is Arctic sea floor
The next great immediate danger are the vast regions of Arctic and subarctic
The third huge methane source is the vast regions of permafrost. As the world
These different methane sources will combine to accelerate the rate of methane
It is certain if the Arctic is not cooled these Arctic methane sources will greatly
A 2010 review of the Arctic carbon budget by D. McGuire et al finds that the
Permafrost holds a currently estimated carbon pool of double atmospheric
The East Siberian Arctic Shelf holds over 90% of Arctic methane hydrate, which
The subArctic Boreal forest is the largest forest store of carbon, even more than
This feedback atmopsheric increase is sustained and in the Arctic has reached a level of 1900 ppb.
Satellite data shows that in 2009 and in 2011-2012 Northern Hemisphere methane was increasing fastest with the eastern Arctic Ocean a significant methane emitter after 2009. In October 2011, the maximal methane concentrations were found over the East Siberian Arctic shelf.
This should be recognized as a planetary emergency because of the recognized potential of an abrupt increase in atmospheric methane leading to abrupt global warming
Dr. Ed Dlugokencky (methane monitoring head for the US federal government) said in a December 2011 interview that if the recent increase had been coming solely from the Arctic, he was fairly certain that science would have detected that by comparing measurements from the Northern and Southern Hemispheres.
In 2007, excess rainfall in the tropics and excess warmth in the Arctic may have led to higher methane emissions from wetlands in both regions, and the excess tropical emissions probably continued into 2008. The methane level of the atmosphere kept rising in 2009, but the reason it did that year is a bit of a mystery. In 2010, excessive rainfall in the tropics may again have been a culprit.
