Accelerating
Towards an Arctic Blue Ocean Event
“For
the last 8,000 years we’ve had [relatively] amazing stability
with constant weather temperatures and sea level. This stability has
allowed the development of agriculture, civilization,
industrialization, and a population of 7 billion and rising. This
apparent stability is entirely a fluke. It is by amazing good luck
that we are here today looking back on the past.”

Arctic Methane Emergency Group

December, 2014
On
the 4th, 5th, and 6th of December of the year 2014, the
Arctic Methane Emergency Group (AMEG) held press briefings at
the COP-20
United Nations Climate Change Conference that
is taking place in Lima, Peru. For those unfamiliar with AMEG,
here is a summary about
them from their website that illustrates their proven track record of
predictions:
AMEG
is a group of determined scientists, engineers, communicators and
others, dedicated firstly to establishing what really is happening to
our planet (especially in the Arctic) using best scientific evidence,
secondly to finding effective and affordable means to deal with the
situation, and thirdly communicating these matters to authority and
the general public.
AMEG
aims to position itself in the centre ground – neither overstating
nor understating the dangers of climate change. We are only alarmist
in the sense that we are drawing attention to the more unpleasant
realities of rapid Arctic warming and climate change, which have been
downplayed or ignored by IPCC, unwittingly backed up by the media. We
are determinedly optimistic as regards promoting an intervention
strategy against all the odds, believing that mankind must have the
collective intelligence to sort out the mess that mankind has got
itself into.
In
early 2012, AMEG gave evidence to the UK’s Environment Audit
Committee in their inquiry on protecting the Arctic. Much of our
evidence was dismissed by government advisers, but all our evidence
has been borne out by subsequent observations and events, including:
the rapid rise in temperature of Arctic ocean and atmosphere; the
dramatic decline of sea ice to a record minimum in September 2012
(following the exponential downward trend we had warned the committee
about); the exponential increase in release of the potent greenhouse
gas, methane, from the Arctic Ocean seabed; the exponential increase
in melting of the Greenland Ice Sheet and consequent sea level rise;
and the continuing disruption of the jet stream patterns we expected
from Arctic warming, with resulting climate change in the form of
weather extremes (despite a continuing hiatus in global warming),
causing widespread crop failures and increase in the food price index
above the crisis level, thus promoting civil conflict in a number of
Asian and African countries where food prices have recently
escalated, including most notably Syria.
Recent
independent research, by scientists in AMEG and elsewhere, puts
beyond reasonable doubt our assertion that the Arctic is locked in a
vicious cycle of warming and melting, with the sea ice well past its
tipping point. The current albedo forcing from snow and sea ice
retreat is now estimated at around 0.4 to 0.5 Watts per square meter,
averaged globally, amounting to 200 to 250 terawatts heating in the
Arctic – more than mankind’s total energy consumption. This
albedo forcing is liable to double within a few years as the snow and
sea ice further retreat. AMEG believes that the vicious cycle of
warming and melting can only be broken by rapid intervention to cool
the Arctic.
Although
AMEG’s research has concentrated on the Arctic and its effect on
climate change, our study of IPCC’s own evidence suggests just how
serious are the long-term prospects of climate change due to both CO2
and methane – far more serious than claimed by IPCC itself. The
carbon budget for CO2 – the allowable amount of CO2 to avoid
dangerous climate change – has already been used up, if one takes
into account the effect of methane and other greenhouse gases. If one
also takes into account the climate forcing through albedo loss in
the Arctic, then it is clear that the world is heading for extremely
dangerous global warming by mid-century, even without Arctic methane.
The only way to head off such a disaster is by reducing the level of
greenhouse gases in the atmosphere well below their current levels,
using a combination of aggressive reduction in both CO2 and methane
emissions but also by removal of CO2 from the atmosphere.
The
videos of all three press briefings are below. They
essentially cover much of the same material, but are all worth
watching for the details that the different speakers give
illustrating mankind’s dire predicament. Following the videos, I
summarize AMEG’s discussions along with their conclusions. We truly
are at a turning point in the survival of our species.
SUMMARY
OF AMEG PRESS BRIEFINGS:
• The tipping point for the collapse of Arctic glaciers has been breached and a runaway meltdown of the North Pole ice cap is currently unfolding. Arctic ice is decaying exponentially. (For a better visualization, picture an area of ice the size of the state of Maine being lost every year since 1979.):
Highly
reflective snow and ice is being replaced by dark sea water which is
much more [absorbent] of solar energy causing the Arctic to warm
much, much faster than the rest of the planet. This is destabilizing
the atmospheric air circulation and ocean circulation. It is reducing
the temperature gradient or difference between the equator and the
pole which slows down the jet stream making it wavier with higher
ridges and troughs. The jet stream has also become prone to
stagnating in the same region. Very warm, humid southerly air can go
to much higher latitudes than before, and cold arctic air can go to
much southerly latitudes than before. This in itself is representing
an enormous positive reinforcing feedback (not positive for
humans) which is carrying more and more heat up into the Arctic
and more and more coldness from the Arctic further south. What this
will do is fracture the jet streams, leading us to a very
different world, a less predictable climatic world where weather
extremes such as torrential rains and extended droughts and floods
come to dominate the weather system. The frequency, severity,
and duration of these events all increase. These events also occur in
regions where we did not have this before. For example, we
get 80cm(32
inches) of snow in the Atacama Desert which
is the driest region of the planet – an unprecedented event. We get
torrential rains where we had desert before. We get desert where we
had moderate temperatures before. This is already happening now with
just 0.85 °C of warming that the world has experienced since
the start of the industrial revolution. This situation is very
dependent on the conditions in the Arctic. As the Arctic continues to
exponentially decline in snow and sea ice cover, these extremes will
undoubtedly have to increase. The physics of the system says so.
Because we now live in a warmer planet, there is more evaporation of
the oceans leading to more water vapor in the atmosphere which fuels
stronger storms. (The atmosphere can hold 7% moisture for every
1°C increase in average temp. Since we have increased the average
temp by ~0.8°C from pre-industrial times, we have 6% more water
vapor in the atmosphere). Because we have changed the chemistry of
the atmosphere, we have changed the planet’s weather and climate.
• Once
we reach a point of no Arctic sea ice, perhaps as early as September
2015, this will create a “blue ocean event” in which all the heat
from the sun will be able to penetrate Arctic waters, vastly
accelerating the rate at which the Arctic is warming. Consequently,
massive disruption of atmospheric circulation and ocean currents
will ensue, thus locking the Arctic into an ice-free state. Global
sea levels will rapidly rise and climate chaos will ramp up.
• The East Siberian Arctic Shelf, containing hundreds to thousands of times more heat trapping gases than what are presently in the atmosphere, is in the process of releasing a catastrophic amount of greenhouse gases.
• Climate models do not take into account fractures, imperfections in the sea floor, regions of unfrozen subsea methane and other weak points in methane deposits. The models simply treat these areas as uniform slabs that will act in a predictable and symmetrical manner.
• Historical ice core and sediment records show numerous instances of the Earth having undergone abrupt climate change of 5-6°C or greater within a very short time period, one or two decades.
• The initial heat-trapping strength of methane(CH4) is up to several hundred times more powerful than CO2 during the first couple decades of its release into the atmosphere before degrading into CO2.
• Collapse of Civilization is assured at a 4°C rise in global temperature.
Scientists
consider a global warming of 6°C to be a threat to the survival of
humanity, and anything beyond an increase of 2°C to be intolerable
(as recorded at the Asia-Europe Summit by Khor, September
2006). - Link
• Even
conservative IPCC projections of BAU predict a 4°C rise in
global temperature by the end of the century and this estimate does
not include the methane release from the Arctic seabed, permafrost
and tundra. No where in its reports does the IPCC state that
a 4°C would be catastrophic to civilization and life on
Earth.
• Simply attempting to “adapt” to anthropogenic climate change is not a realistic option.
• The meme of money and profit holds sway over all of society.
• The operating system of global civilization, i.e. neoclassical economics, is fatally flawed and it will kill us.
• The consequences of predicted drought from global warming will make food production impossible in most of the world…
AMEG’S
CONCLUSIONS ARE:
• A life-affirming system of ecological economics must replace the current ecocidal model of neoclassical economics.
• Institutions must divest from fossil fuel investments and burst the carbon bubble.
• Techniques for cooling the Arctic need to be implemented now, such as spraying salt into the atmosphere to thicken clouds. Additionally, carbon sequestration techniques need to be implemented now, such as biochar burial which is a carbon negative technology that also enriches soil fertility.
• The world must recognize that a 2°C target is not the benchmark we need to worry about right now. We need to worry about and immediately deal with the destabilization and disruption of our climate and weather patterns that are already occurring today at 0.85 °C.
• Only a concerted international effort will provide us with a chance to mitigate and adapt to climate change by building a deep toolbox of approaches to reducing greenhouse gas emissions. However, reducing emissions alone will not be sufficient. An active withdrawal of CO2 from the atmosphere will need to be a part of managing climate change.
AMEG
does not mention the Antarctic which was recently found to be melting
three times faster than a decade ago:
The
glaciers in the embayment lost mass throughout the entire period. The
researchers calculated two separate quantities: the total amount of
loss, and the changes in the rate of loss.
The
total amount of loss averaged 83 gigatons per year (91.5 billion U.S.
tons). By comparison, Mt. Everest weighs about 161 gigatons, meaning
the Antarctic glaciers lost a Mt.-Everest’s-worth amount of water
weight every two years over the last 21 years.
The
rate of loss accelerated an average of 6.1 gigatons (6.7 billion U.S.
tons) per year since 1992.
From
2003 to 2009, when all four observational techniques overlapped, the
melt rate increased an average of 16.3 gigatons per year — almost
three times the rate of increase for the full 21-year period. The
total amount of loss was close to the average at 84 gigatons.
Also
in the news a few months ago was the realization that Greenland’s
ice sheet loss has doubled
in just the last five years.
Greenland’s ice is much
more unstable and prone to collapse than
previously thought, and it alone holds enough ice to raise sea
levels by nearly twenty-three feet. Paul Beckwith notes that the
rate of change in ice melt from Greenland and Antarctica has doubled
every seven years for the last couple decades and that if we
continue on this trend, then the world will indeed experience a
sea level rise of nearly twenty-three feet by 2070.
Last
month a seemingly reassuring headline stated that ‘Alaska
shows no signs of rising Arctic methane‘
according to NASA’s CARVE project (Carbon in Arctic Reservoirs
Vulnerability Experiment), but any hopes about the ticking
methane time bomb in the Arctic were quickly dashed after reading the
article:
…High
concentrations of atmospheric
methane have
been measured at individual Arctic sites, especially in Siberia. This
adds to the concern that massive methane releases are already
occurring in the far North. NASA’s multiyear Carbon in Arctic
Reservoirs Vulnerability Experiment (CARVE) is the first experiment
to establish emission rates for a large region of the Arctic…
Alaska
composes about one percent of Earth’s total land area, and its
estimated annual emissions in 2012 equaled about one percent of total
global methane emissions. That means the Alaskan rate was very close
to the global average rate.
“That’s
good news, because it means there isn’t a large amount of methane
coming out of the ground yet,”
said lead author Rachel Chang, formerly at Harvard University,
Cambridge, Massachusetts, and now an assistant professor and Canada
Research Chair in Atmospheric Science at Dalhousie University,
Halifax, Nova Scotia.
Charles
Miller of NASA’s Jet Propulsion Laboratory, Pasadena, California,
the principal investigator for CARVE, noted that results
from a single year cannot show how emissions might be changing from
year to year. “The 2012 data don’t preclude accelerated change in
the future,” he
said.
Vast
amounts of carbon are stored in undecayed organic matter—dead
plants and animals—in Arctic permafrost and peat. Scientists
estimate that there is more than twice as much carbon locked in the
frozen North as there is in the atmosphere today. The organic
material won’t decay and release its carbon as long as it stays
frozen. But climate change has brought warmer and longer summers
throughout the Arctic, and permafrost soils are thawing more and
more. If large amounts of undecayed matter were to defrost, decompose
and release methane and carbon dioxide into the atmosphere, the
impact on global temperatures would most likely be enormous.
Because
no other program has made measurements as comprehensive and
widespread as CARVE’s, Chang said, “One
of the challenges is that we have nothing to compare our results to.
We can’t say whether emissions have already increased or stayed the
same. Our measurements will serve as a baseline.”
We
already know that methane levels have increased two-and-a-half times
since the pre-industrial era and “since 2007 atmospheric
methane has been on a renewed sustained increase… due to planetary
feedback emissions.” Methane has “more than doubled its
800,000 [year] maximum”:
This
increase in atmospheric methane started as a result of carbon
feedback feedback methane (CH4) from anomalously high temperatures in
the Arctic and greater than average precipitation in the tropics,
rather than from increased industrial emissions (Dlugokencky et al,
2009). - Link
We
also know that scientists continue to be shocked and awed at the
increasingly accelerated rate at which glaciers around the world are
melting. Essentially, industrial civilization is whistling past the
graveyard.
Because
of AMEG’s honest assessment about the climatic state of
the world and the horrific future mankind faces, I support their
efforts. We have no time left for philosophical musings about the
ethics of AMEG’s geo-engineering ideas to cool the Arctic or
debating why, how, and who is responsible for the mess we are in.
The
Blue Ocean Event is coming and time is not on our side.
