  1. Here is what these same researchers were thinking a year ago. http://www.thecuttingedgenews.com/index.php?article=12040&pageid=&pagename=
  2. Methane is relatively short lived in the atmosphere, 6-12 years. It took over 6,000 years for the ice-age ice to melt. Even if there was 100 times as much methane, the rate and the air concentration would still be lower. It is the abruptness of this Arctic fart that is the danger.
  3. "SHOCK THE WORLD OF SCIENCE: Arctic Ocean Methane threatens Earth" Citeste mai mult pe REALITATEA.NET: http://www.realitatea.net/soc-in-lumea-stiintifica-metanul-din-oceanul-arctic-ameninta-pamantul_895855.html#ixzz1gdd1r935 It's unbelievable, "Semiletov said. "The threat of methane gas" http://www.haberturk.com/dunya/haber/696566-metan-gazi-tehdidi "Melting ice will free hundreds of millions of tons of methane" http://www.khoahoc.com.vn/congnghemoi/cong-nghe-moi/36676_Bang-tan-se-giai-phong-hang-tram-trieu-tan-khi-metan.aspx
  4. You did not notice that all of these articles are written by Igor Semiletov. If you read all of them, you will know some but not all of what he knows about the arctic and carbon. He is shocked and astonished by the methane release. It is his expert opinion that the methane release he witnessed and measured is shocking, astonishing, and unprecedented in human history. If this experts description is any where near accurate, many gigatons of methane have been dumped into the atmosphere this year. That is enough to have world wide impact. If you want to ignore this until the paper is published you are free to do so. In fact please ignore it. Stop spamming with inane banalities.
  5. If an expert like Igor Semiletov is "shocked" and "alarmed" maybe we should be too.

  7. "Earlier we found torch-like structures like this but they were only tens of metres in diameter." "This is the first time that we've found continuous, powerful and impressive seeping structures, more than 1,000 metres in diameter." "Over a relatively small area we found more than 100, but over a wider area there should be thousands of them." "Scientists estimate that there are hundreds of millions of tonnes of methane gas locked away beneath the Arctic permafrost" "Dr Semiletov's team published a study in 2010 estimating that the methane emissions from this region were about eight million tonnes a year" "In late summer, the Russian research vessel Academician Lavrentiev conducted an extensive survey of about 10,000 square miles of sea off the East Siberian coast." "on a scale not seen before. Some plumes were a kilometre or more wide and the emissions went directly into the atmosphere – the concentration was a hundred times higher than normal." How mutch more data do you need to see that this is not good?
  8. sorry, contrary to forum rules, I posted this graph without an explanation. This is not good("I have a bad feeling about this.").
  9. Does anyone know of any real-time monitoring of methane in the arctic?
  10. "1. I'm pretty sure the Arctic is not boiling." Its not boiling steam, its boiling methane" "2. How did you arrive at that million percent factor?" The methane vents increased from "tens of meters " to "over a thousand meters in diameter" a factor on the order of 100. Area is the square of diameter so the area factor is 10,000 or 1,000,000%. Also they reported that the vents had also increased in number and strength. "3. The article comes from a source that is known to be tabloidish and alarmist. Just look at their silly title." The article is primarily quotes in context from a known and respected researcher. Unless they are lying, and if they are I am sure the researcher will soon correct the record, the information comes from a reliable source, the researcher. " 4. What historical records of methane release in that particular area, or even the Arctic as a whole, do we have to compare this to?" The blow out in the Gulf of Mexico caused a methane vent tens of meters in diameter. So, this is like 1,000,000 blow outs without the oil slick. We haven't had a blow out in the arctic that I am aware of ... yet. "5. Even if your figure was correct and the Arctic had released a millions times more methane this year, wouldn't that be bringing out the "severe and sudden" warming the article references? Instead, we've seen global temperature drop rapidly over the past several months." Not, "a millions times" 10,000 times or a million %. The past several months, since mid August, the arctic insolation has been next to zero or zero. GHG trap sunlight. There has been no sunlight to trap. The effect of this will be felt in the spring.
  11. So, now the arctic is boiling methane, by a factor of 1,000,000%, in one year, and this is not alarming? You must be on Gilligan's island.
  12. "The scale and volume of the methane release has astonished the head of the Russian research team who has been surveying the seabed of the East Siberian Arctic Shelf off northern Russia for nearly 20 years." "Earlier we found torch-like structures like this but they were only tens of metres in diameter. This is the first time that we've found continuous, powerful and impressive seeping structures, more than 1,000 metres in diameter. It's amazing," Dr Semiletov said. "I was most impressed by the sheer scale and high density of the plumes. Over a relatively small area we found more than 100, but over a wider area there should be thousands of them." A 100 fold increase in diameter equals a 10,000 fold increase in area or a 1,000,000% increase in methane venting from the arctic. In one year. I am alarmed! Lets talk about a hockey stick. Or a tipping point. We are no longer in control. The arctic can increase its GHG faster than we can diminish (lol) ours. Have a nice day,
  13. "Retreat of Arctic sea ice releases deadly greenhouse gas." http://www.independe...as-6276134.html It looks like the sst anomaly is destabilizing methane hydrate big time. Could this be the missing feedback that explains why the models are underestimating the melt?
  14. do not freak out. It is not as bad as it looks. But it is worse than it appears.
