Global Extinction within one Human Lifetime as a Result of a Spreading Atmospheric Arctic Methane Heat wave and Surface Firestorm Abstract Although the sudden high rate Arctic methane increase at Svalbard in late 2010 data set applies to only a short time interval, similar sudden methane concentration peaks also occur at Barrow point and the effects of a major methane build-up has been observed using all the major scientific observation systems. Giant fountains/torches/plumes of methane entering the atmosphere up to 1 km across have been seen on the East Siberian Shelf. This methane eruption data is so consistent and aerially extensive that when combined with methane gas warming potentials, Permian extinction event temperatures and methane lifetime data it paints a frightening picture of the beginning of the now uncontrollable global warming induced destabilization of the subsea Arctic methane hydrates on the shelf and slope which started in late 2010. This process of methane release will accelerate exponentially, release huge quantities of methane into the atmosphere and lead to the demise of all life on earth before the middle of this century. Introduction The 1990 global atmospheric mean temperature is assumed to be 14.49 oC (Shakil, 2005; NASA, 2002; DATAWeb, 2012) which sets the 2 oC anomaly above which humanity will lose control of her ability to limit the effects of global warming on major climatic and environmental systems at 16.49 oC (IPCC, 2007). The major Permian extinction event temperature is 80 oF (26.66 oC) which is a temperature anomaly of 12.1766 oC above the 1990 global mean temperature of 14.49 oC (Wignall, 2009; Shakil, 2005). Results of Investigation Figure 1 shows a huge sudden atmospheric spike like increase in the concentration of atmospheric methane at Svalbard north of Norway in the Arctic reaching 2040 ppb (2.04 ppm)(ESRL/GMO, 2010 - Arctic - Methane - Emergency - Group.org). The cause of this sudden anomalous increase in the concentration of atmospheric methane at Svalbard has been seen on the East Siberian Arctic Shelf where a recent Russian - U.S. expedition has found widespread, continuous powerful methane seepages into the atmosphere from the subsea methane hydrates with the methane plumes (fountains or torches) up to 1 km across producing an atmospheric methane concentration 100 times higher than normal (Connor, 2011). Such high methane concentrations could produce local temperature anomalies of more than 50 oC at a conservative methane warming potential of 25. And so on........

Remember this BBC story? Turns out it is another one for the Climate FAIL file. See whole story here: wattsupwiththat.com/2012/...eabed-in-2009-never-mind/ Well, a new more comprehensive on-site study has been done, and it has just been announced by the Helmholtz Centre for Ocean Research Kiel: Gas Outlets off Spitsbergen Are No New Phenomenon Expedition to the Greenland Sea with Surprising Results Marine scientists from Kiel, together with colleagues from Bremen, Great Britain, Switzerland and Norway, spent four and a half weeks examining methane emanation from the sea bed off the coast of Spitsbergen with the German research vessel MARIA S. MERIAN. There they gained a very differentiated picture: Several of the gas outlets have been active for hundreds of years. Frequent storms and sub-zero temperatures – nature drove the marine researchers that were assessing gas outlets on the sea bed off the coast of Spitsbergen for four and a half weeks to their limits. Nevertheless the participants were very pleased when they returned: “We were able to gather many samples and data in the affected area. With the submersible JAGO we even managed to form an impression of the sea bed and the gas vents” summarised the chief scientist Professor Dr. Christian Berndt from GEOMAR | Helmholtz Centre for Ocean Research Kiel. The reason for the expedition was the supposition that ice-like methane hydrates stored in the sea bed were dissolving due to rising water temperatures. “Methane hydrate is only stable at very low temperatures and under very high pressure. The gas outlets off Spitsbergen lie approximately at a depth which marks the border between stability and dissolution. Therefore we presumed that a measurable rise in water temperature in the Arctic could dissolve the hydrates from the top downwards” explained Professor Berndt. Methane could then be released into the water or even into the atmosphere, where it would act as a much stronger greenhouse gas than CO2. In fact, what the researchers found in the area offers a much more differentiated picture. Above all the fear that the gas emanation is a consequence of the current rising sea temperature does not seem to apply. At least some of the gas outlets have been active for longer. Carbonate deposits, which form when microorganisms convert the escaping methane, were found on the vents. “At numerous emergences we found deposits that might already be hundreds of years old. This estimation is indeed only based on the size of the samples and empirical values as to how fast such deposits grow. On any account, the methane sources must be older” says Professor Berndt. The exact age of the carbonates will be determined from samples in GEOMAR’s laboratories. “Details will only be known in a few months when the data has been analysed; however the observed gas emanations are probably not caused by human influence” says Berndt. There are two other possible explanations instead: Either they are symptoms of a long term temperature rise or they show a seasonal process where gas hydrates continuously melt and reform. Another interesting observation made on the expedition, was that a very active microbial community that consumes the methane has established itself on the sea bed. “We were able to detect high concentrations of hydrogen sulphide, which is an indication of methane consuming microbes in the sea bed, and, with the help of JAGO, discovered typical biocoenoses that we recognised from other, older methane outlets” explained microbiologist Professor Dr. Tina Treude from GEOMAR, who also took part in the expedition. “Methane consuming microbes grow only slowly in the sea bed, thus their high activity indicates that the methane has not just recently begun effervescing.” Colleagues from Bremen, Switzerland, Great Britain and Norway worked alongside marine scientists from GEOMAR and from the Cluster of Excellence “The Future Ocean”. “The study of the gas outlets in the Norwegian Sea is a good example for combined European research” stressed Professor Berndt. Hence German scientists recovered an ocean floor observatory, installed by the British research vessel James Clark Ross a year ago during a joint expedition of the National Oceanography Centre Southampton and the Institut français de recherche pour l’exploitation de la mer (Ifremer). “Understanding the ocean as a system is a challenge that only works in international co-operations” emphasized Berndt. The analysis of the gathered data will also be carried out internationally.
Just like Green on Blue killings......LMFAO The 1990 global atmospheric mean temperature is assumed to be 14.49 oC (Shakil, 2005; NASA, 2002; DATAWeb, 2012) which sets the 2 oC anomaly above which humanity will lose control of her ability to limit the effects of global warming on major climatic and environmental systems at 16.49 oC (IPCC, 2007). The major Permian extinction event temperature is 80 oF (26.66 oC) which is a temperature anomaly of 12.1766 oC above the 1990 global mean temperature of 14.49 oC (Wignall, 2009; Shakil, 2005). Or more simply: 2oC rise over 1760 baseline.....but we were out of control with 1oC...... Good News: USSA/Russian/German/Austrian Lake E Core Samples show that a 4oC rise will trigger a New ICe Age.
Remember the panic over methane seeping out of the Arctic seabed in 2009? Never mind. Posted on September 25, 2012 by Anthony Watts
