In essence it says,<br /><br />Good news; conservative estimate 8 Tg.<br /><br />Bad news: Observed flux exceed estimated by up 3 orders of magnititude...prorating these numbers to the rest of the hotspots adds 3.5 Gt (Ira Leifer) to annual methane release from the ESAS. This is enough to trigger abrupt climate change.(Archer, 2005)<br /><br />Alvia Gaskills summary to the US DoE suggest such a scenario will precipitate a mass extinction via abrupt global warming.<br /><br />Now in December 2011 Igor says torches that were only 10m wide have expanded to over 1000m. So this is over and above that of November 2010.<br /><br />It is pretty obvious where we are and where we're headed. If things are as bad as described than there will surely be some intentional suppression. According to Wasdell NASA detected first hydrate release in 2006 but was instructed by the US govt not to tell anyone.<br /><br /><br />www.globalwarmingmlight.blogspot.com<br />www.geo-engineering.blogspot.com<br />www.cid-yama.livejournal.com<br /><br />Hopefully Lovelock is right and we're only headed to a 4-5 degree hotter world, not a 15 degree world as described by Gaskill/Schellnhuber.<br /><br />S, posted from mobileAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-11191178460309970722012-01-09T11:21:36.111-06:002012-01-09T11:21:36.111-06:00Dear Shaheer,
Thank you for your comment.
Based ...Dear Shaheer,<br /><br />Thank you for your comment.<br /><br />Based on what we know right now, it is not yet clear that we have entered a phase of abrupt global warming.<br /><br />The amounts of methane released so far do not indicate this.<br /><br />You may be right, but we just do not know this yet.<br /><br />Certainly, conditions in the Arctic are deteriorating.<br /><br />Sincerely,<br /><br />TenneyTenney Naumerhttps://www.blogger.com/profile/11843130378338023902noreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-9651980573728294312012-01-09T03:01:33.726-06:002012-01-09T03:01:33.726-06:00I think the last line is especially important. Tha...I think the last line is especially important. That their findings may significantly alter our world view.<br /><br />Based of what Shakhova, Semilitov, and the NFS has been saying the last 5 years, and based on latest sea ice volume data + visual descriptions of large methane hydrate eruptions, it seems obvious that we have entered a period of abrupt global warming. The danger is clear, I don't see what the holdup is. David Archer himself has said the worst case scenario is global warming causing the release of hundreds of billions of tons of methane over a decade, resulting in mass extinction. <br /><br />I think it is important SRM type geoengineering be deployed immediately as we may have to shield a significant amount of sunlight if even a small fraction of arctic hydrates escape. This will have to be much stronger than the present global dimming due to air pollution.<br /><br /> It is also important to begin planning for community food security, as well as developing alternative forms of nutrition. Norway has already developed some type of synthetic food. Industrial agriculture will not survive well in a period of abrupt global warming unless temperatures are kept cool through heavy geoengineering. <br /><br />ShaheerAnonymousnoreply@blogger.com
