Not only will the methane from rotting buried vegetation collect at the bottom of an ice sheet as methane clathrate once it reaches a thickness of about 500m but all the seeps from coal, oil and shale will likewise accumulate. A really old ice sheet pushes well into the non accumulation zone of the earth and once a Milankovitch nudge begins the melt, all this methane would come out into the atmosphere. On an instantaneous level it is vastly more powerful a green house gas than Carbon dioxide and would power the warming. It then remains in the atmosphere as Carbon dioxide. Here might be part of the explanation of why Carbon dioxide follows temperature upwards at the end of a glacial.<br />http://mtkass.blogspot.co.nz/2011/09/continental-glacier-meltdown.htmlWilliam Hughes-Gameshttps://www.blogger.com/profile/06184766974497951683noreply@blogger.comtag:blogger.com,1999:blog-1641696877572843922.post-26993571632749861802013-05-23T03:08:50.338-07:002013-05-23T03:08:50.338-07:00Yeah, it's always good to try and find the bes...Yeah, it's always good to try and find the best terms. The graph gives the 'daily peaks', or if you like the highest reading recorded for each day of the period covered by the chart. Since the highest reading ('peak') for the period covered by the chart was 2249 ppb, this was in the title of the post. But an even higher reading was recorded later (of 2266 ppb on August 17, 2013), as described in a <a href="http://methane-hydrates.blogspot.com/2013/05/is-global-warming-breaking-up-the-integrity-of-the-permafrost.html" rel="nofollow">more recent post</a>.

Are there known processes that could absorb CO2 but not methane? And, all this is happening under the ice, half to a mile deep, right?Anonymoushttps://www.blogger.com/profile/17372903404313231061noreply@blogger.comtag:blogger.com,1999:blog-1641696877572843922.post-5563075508820335572013-05-16T04:37:00.150-07:002013-05-16T04:37:00.150-07:00It does look like a complex destabilization that t...It does look like a complex destabilization that took a long time to initiate is starting to manifest in surface release of methane above thick Eastern Antarctic ice sheet. But I keep thinking of that finding about higher carbon dioxide levels causing ice to become weaker physically due to the competition for bonding during refreezing particularly at end of crack elongation. An antidote for the changes mankind has initiated to Earth is going to take some doing now..<br />Mankind is one heck of a can of work going rancid when it comes to wrecking us.<br />There is a meeting on divvying up the Arctic for exploitation happening in Sweden while there is news of hollow cement canisters dropped with poison gas in Syria on civilians and a whole media system and monetary exchange that is nuts..<br />I don't know how to bring civilization to bear on taking on this project to save Earth. -What can a person say.. But this is not our world to destroy but to defend. It is our job and knowledge of what's happening wouldn't be made available I'm thinking to the little guy on such important of an issue if it was not still within possibility to make change..
