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.
