"History, real solemn history, I cannot be interested in.... I read it a little as a duty; but it tells me nothing that does not either vex or weary me. The quarrels of popes and kings, with wars and pestilences in every page; the men all so good for nothing, and hardly any women at all - it is very tiresome." Jane Austen spoken by Catherine Morland in 'Northanger Abbey'
As the report concludes in part:
"Governments must stop spending financial and political capital to further the interests of one industry whose aspirations will literally devastate the planet, at the expense of all of us."
Methane: The Arctic's hidden climate threat.
Natalia Shakhova's latest paper. Jun 23, 2019
Even with existing levels of warming and melting of the Arctic region, submarine methane releases linked to clathrate breakdown have been discovered, and demonstrated to be leaking into the atmosphere. A 2011 Russian survey off the East Siberian coast found plumes wider than one kilometer releasing methane directly into the atmosphere. According to monitoring carried out in 2003/2004 by Shakhova et al., the surface layer of shelf water in the East Siberian Sea and Laptev Sea was supersaturated up to 2500% relative to then present average atmospheric methane content of 1.85 ppm. Anomalously high concentrations (up to 154 nM or 4400% supersaturation) of dissolved methane in the bottom layer of shelf water suggest that the bottom layer is somehow affected by near-bottom sources. Considering the possible formation mechanisms of such plumes, their studies indicated thermoabrasion and the effects of shallow gas or gas hydrates release. Wikipedia Arctic Methane Emissions Page
New Arctic lakes could soon be a major source of atmospheric methane. August 20, 2018
For centuries, a massive store of carbon has been locked underground in the Arctic's permanently frozen soil known as permafrost. As Earth's climate continues to warm, that carbon has begun to leach into the atmosphere, the result of microbes waking up and digesting once-frozen organic materials. A new NASA-funded study focuses on a mechanism that could accelerate the release of this atmospheric carbon, the result of thermokarst lakes. These lakes form when thawing permafrost causes the ground to slump, creating a depression that collects rain and snowmelt and perpetuates a cycle of further permafrost thaw. NASA August 2018

"Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement; and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it." George Santayana Vol. I, Reason in Common Sense
