A we say farewell to 2014 here are a few of the videos about abrupt climate change and the Arctic methane clathrate gun.
Arctic Death Spiral and the Methane Time Bomb
The Arctic Methane Monster's Rapid Rise
Global
warming is a lot worse than the 'right wing' wants you know or
believe.
Researcher
Jennifer Hynes offers a riveting, comprehensive, scientific Power
Point presentation about the Arctic atmospheric "methane global
warming veil", a spiral of runaway global warming.

Nature
Bats Last with show host Guy McPherson and guests Peter Melton &
Reese Jones. In this more intimate, conversational show, Guy, Peter
and Reese discuss personal experiences and feelings regarding climate
change, near-term human extinction possibilities, good and evil, life
and death, spirituality, going dark, and other fascinating topics.
From Paul Beckwith
I
am a part-time professor teaching climatology/meteorology in the
Department of Geography at the University of Ottawa, Canada. I am
also working full-time on my Ph.D. researching abrupt climate change,
both present day and in the paleorecords of the deep past. I am also
an engineer (B.Sc. in Engineering Physics) and a physicist (M.Sc. in
Laser Optics). I am very active in educating the public via social
media on the science and extreme near-term risks of abrupt climate
change (Facebook: Paul Beckwith; Twitter: PaulHBeckwith; YouTube,
Google+, Tumblr, etc…please follow me)

Heat moves from the warm equator to the cold poles of the Earth via
the atmosphere circulation patterns and ocean currents. Due to human
emissions of greenhouse gases the planet system is warming. In the
Arctic, this warming is causing the sea ice volume and spring
terrestrial snow cover to exponentially decline exposing the darker
underlying surfaces (ocean water and permafrost, respectively). These
darker surfaces absorb more solar energy, and thus there is an
amplification of warming of the Arctic at rates 5 to 8 times faster
than the overall warming average. This decreases the temperature
difference between the Arctic and the equator and thus decreases the
heat moving from the equator northward resulting in a slowing of the
westward movement of the high speed winds making up the jet stream.
The jet stream becomes wavier and leads to an increase in the
frequency, intensity, duration, and spatial extent location and
variation.
3.
The US naval graduate research lab high resolution Arctic sea ice
model (Maslowski) projects the sea ice could vanish in September,
2015 or 2016 for the first time. In the first year that this happens,
the open Arctic ocean state will only last for a few weeks to a month
or so. Within a year or two, the open water duration (no sea ice)
will last for several months, and within a decade or so the positive
feedbacks will likely clear out the Arctic ocean basin for most of
the year. Clearly this state will represent a very different planet,
with a much higher global average temperature (as much as 5 to 6
degrees C warmer within a few decades) in which snow and ice in the
northern hemisphere becomes very rare or even vanishes year round.
4.
As the planet transitions through this abrupt climate change there
will be wrenching turmoil and conflict for human civilizations. We
are in early stages of this abrupt change. As the extreme weather
events ramp up they will result in a frenzy of human activity to
attempt to adapt and mitigate. Essentially, this tipping point in the
Arctic will inevitably result in a tipping point in human response to
the problem.
5.
When the tipping point in human response and understanding of the
grave risks of abrupt climate change occurs then humanity will put a
steep price on carbon and slash emissions with a full speed ahead
surge in renewable energy and probably next-generation nuclear power
generation. We will also implement CDR (Carbon dioxide removal) and
SRM (solar radiation management) programs, beginning with attempts to
cool the Arctic to keep the methane and carbon dioxide from
explosively escaping from the terrestrial permafrost and marine
sediments (containing subsea permafrost and clathrates). In the
transitions, many governments will fall and martial law will be
implemented in many countries as there is a resource scramble for
ever scarcer fresh water and food.

Paul
