the body of the work and David Petraitis for the following summary;
I
get a lot of questions from people asking “What is near term?”
When I say NTHE. And so I would like to give this long quote from
Malcolm Light’s December 2013 papr for you all to think about and
to pass on to your friends and loved ones. Dire, immediate near term…
Use this to make your plans with your loved ones.
The
best estimate of the time that methane eruption in the Arctic will
produce a mean atmospheric temperature of 8oC leading to total global
deglaciation and the major extinction of all life on Earth
(IPCC, 2007) is 2050.6 +- 3.4 (N=8) with a total range from 2042.2 to
2052.8 (Figures 1 and 2, Tables 1a – 1d, Table 2).
The
lowest range extinction date of 2042.2 is 2.6 years later than to the
previous best estimate for the extinction of 3/4 of the Earth’s
surface (2039.6) using aerial growth and methane GWP methods (Light,
2012 Figure 3) and is close to Carana’s (2012) best estimate from
runaway global warming (Figure 4). The mean time of extinction of the
Northern Hemisphere was previously fixed between 2024 and 2039
(Light, 2012). The best estimate of final extinction (2050.6) is 3
years later than the mean estimate for the Southern Hemisphere of
2047.6 (Range 2038 to 2057)(Figure 3).

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.
