Will the Anthropocene last for only 100 years?

On November 9, 2013, methane levels as high as 2662 ppb (parts per billion) were recorded, as indicated by the red dot on the image below.

This image, from an earlier post, gives an idea of the height of this level compared to historic methane levels, and how fast levels of methane (CH4) have been rising compared to levels of two other greenhouse gases, i.e. carbon dioxide (CO2) and nitrous oxide (N2O).

CO2 concentrations in the atmosphere have now risen to levels well above the 400 parts per million (ppm), as illustrated by the graph below, from keelingcurve.ucsd.edu. This 400 ppm is 143% the pre-industrial peak level of 280 ppm.

Paleorecords show that greenhouse gases levels go up and down in lockstep with temperatures in history. The image below shows that carbon dioxide levels back in history typically moved between approximately 180 ppm and 280 ppm, a difference of 100 ppm. Since 1950, CO2 levels have risen by roughly the same difference.


In a fascinating lecture, Dr Jan Zalasiewicz suggests that the Anthropocene started around 1950, when levels of greenhouse gases started to rise exponentially, in line with the rise of fossil fuel use, as also illustrated by the image below.


The image below, from an earlier post, shows that temperatures typically moved up and down by roughly 10 degrees Celsius between a glacial and interglacial phase of the ice ages, suggesting that a 100 ppm rise of carbon dioxide and 300 ppb rise of methane go hand in hand with a 10°C temperature rise.

Many eminent scientists have warned that the high current carbon dioxide levels have already locked us in for a future temperature rise of several degrees Celsius, a rise that is yet to fully manifest itself and that is only held off by the temporary masking effect of sulfur dioxide that is emitted when burning fuel (especially coal) and by the (decreasing) capacity of oceans, ice sheets and glaciers to act as a buffer for heat. Once the masking effect of sulfur dioxide ends and the Arctic sea ice collapses, a huge sudden rise in temperature can be expected, hitting vulnerable pools (see image below) which would accelerate the temperature rise even more and could cause temperatures to rise by another 10°C within decades.


The scenario of such a huge rise in temperature becomes a distinct possibility when considering the combined warming impact of carbon dioxide, methane, nitrous oxide, water vapor and albedo changes, and the vulnerability of some of the terrestrial and marine carbon pools. Also note that, while the above Unesco image gives an estimate of 104 or 10,000 Gt C for ocean methane hydrates, several studies give even higher estimates, as illustrated by the image below, from Pinero et al.


The amount of carbon stored in hydrates globally was in 1992 estimated to be 10,000 Gt (USGS), while a later source gives a figure of 63,400 Gt C for the Klauda & Sandler (2005) estimate of marine hydrates. A warming Gulf Stream is causing methane eruptions off the North American coast. Furthermore, methane appears to be erupting from hydrates on Antarctica, on the Qinghai-Tibetan Plateau and on Greenland. In just one part of the Arctic Ocean alone, the East Siberian Arctic Shelf (ESAS), up to 1700 Gt of methane is contained in sediments in the form of methane hydrates and free gas. A sudden release of just 3% of this amount could add over 50 Gt of methane to the atmosphere, i.e. some seven times what is in the atmosphere now, and experts consider such an amount to be ready for release at any time.

Importantly, methane levels have risen even more strongly than carbon dioxide levels. As the image at the top of this post shows, the current methane level is 250% its pre-industrial peak level, i.e. 1100 ppb above the pre-industrial peak level of 700 ppb. Historically, methane has only moved by some 300 ppb between a glacial and interglacial phase of the ice ages. IPCC/NOAA figures suggest that global mean methane levels have been rising by 5 or 6 ppb annually over recent years and there are some worrying indications that the rise of methane levels might accelerate even further.

To obtain mean methane abundance, measurements are typically taken at an altitude of 586 mb, as methane typically shows up most prominently at this altitude. Indeed, mean methane levels were highest at this altitude in April 2013, at just under 1800 ppb. Looking at mean global methane levels in April 2014 at this altitude, one could at first glance conclude that the situation had not changed much, and that 2014 methane levels had merely risen by a few ppb, in line with IPCC data. So, at first glance one might conclude that there may appear to be only a minimal rise (if any at all) in global mean methane levels when taking measurements at lower altitudes.

The image below illustrates this. What should be added is that the analysis used only selected altitudes and only used part of all data. So, further analysis may be necessary to verify these findings.



Importantly, closer examination of above graph shows that the situation is dramatically different when looking at the rise in methane levels at higher altitudes. A huge rise in mean methane levels appears to have taken place, to the extent that the highest mean level is now reached at 469 mb. Overall, the average rise in methane across the altitudes that are highlighted in the image is no less than 16 ppb.

The table below shows the altitude equivalents in mb (millibar) and feet.
56925 feet44689 feet36850 feet30569 feet25543 feet19819 feet14383 feet8367 feet1916 feet
74 mb147 mb218 mb293 mb367 mb469 mb586 mb742 mb945 mb

As the image below illustrates, this rise appears to go hand in hand with much higher peak readings, especially at higher altitudes. It appears that the additional methane originates from the higher latitudes of the Northern Hemisphere and has over the past few months moved closer to the equator, which is what typically occurs as methane rises in altitude.


Peak readings in above image are averages over April. On specific days, peak readings could be much higher, e.g. on April 28, 2014, methane levels were recorded as high as 2551 ppb at 469 mb.

As said, there appears to be a 16 ppb rise when comparing global mean methane levels between April 2013 and April 2014. Indeed, the culprit appears to be the rapid rise of methane emissions from hydrates that has been documented by this blog and that I estimated to amount to 99 Tg annually, as illustrated by the image below, from an earlier post.


So, it appears that the rise of methane in the atmosphere is accelerating. What can we expect? As temperatures can be expected to continue to rise and as feedbacks start to kick in, this may well constitute a non-linear trend. The image below shows a polynomial trend that is contained in IPCC AR5 data from 1955 to 2011, so they didn't include this recent steep rise. Nonetheless, the polynomial trendline points at methane reaching mean global levels higher than 3000 ppb by the year 2030. If methane starts to erupt in large quantities from clathrates underneath the seafloor of the Arctic Ocean, this may well be where we are heading.
So, how high could temperatures rise? Worryingly, a non-linear trend is also contained in the temperature data that NASA has gathered over the years, as described in an earlier post. A polynomial trendline points at global temperature anomalies of 5°C by 2060. Even worse, a polynomial trend for the Arctic shows temperature anomalies of 4°C by 2020, 7°C by 2030 and 11°C by 2040, threatening to cause major feedbacks to kick in, including albedo changes and methane releases that will trigger runaway global warming that looks set to eventually catch up with accelerated warming in the Arctic and result in global temperature anomalies of 20°C+ by 2050.


Without action, it appears that the Antropocene will lead to extinction of the very human beings after which the era is named, with the Anthropocene only running from 1950 to 2050, a mere 100 years and much too short to constitute an era. In that case a better name would be the Sixth Extiction Event, as also illustrated by the image below, from an earlier post.


In conclusion, it's high time that we start acting as genuinely wise modern human beings and commit to comprehensive and effective action as discussed at the Climate Plan blog.

BREAKTHROUGH DOCUMENTARY EXPOSES SEVERE ARCTIC METHANE THREAT

by Gary Houser



BREAKTHROUGH DOCUMENTARY EXPOSES SEVERE ARCTIC METHANE THREAT:
Climate Movement Must Grasp Danger Beyond Human-Generated Carbon

"Last Hours expertly explains how we got here, and what will happen if we don't work together to stop it. It is a needed and urgent call to action."
— Former Vice-President Al Gore [1]
"In the 18th century, Edmund Burke wrote, 'Those who don't know history are destined to repeat it.' Many years later, Last Hours makes clear how much we have to learn from our planet's history to truly understand the potent threat of trapped methane."
 Maggie Fox, President, Climate Reality Project (started by Al Gore) [2]
“It's not clear that civilization could survive that extreme of a climate change.”
 world renowned climate scientist James Hansen, referring to the devastating level of global warming that could result from a major release of super greenhouse gas methane [3]
The climate movement has come a long way. Despite vociferous opposition from the wealthiest corporations on earth, it has refused to be relegated to the sideline and by sheer determination has forged a path into public consciousness. A major coalition has formed in opposition to the tar sands pipeline, and many good-hearted people are giving their all - including nonviolent civil disobedience - in spirited resistance. This writer is a part of that movement.

A Larger Carbon Threat Beyond Human-Generated Emissions -
It is absolutely necessary to continue the struggle to rein in human-generated emissions of carbon dioxide. But what has been missing in this movement is an awareness that these emissions are now on track to trigger a release of an even larger and more potent reservoir of greenhouse gases that has until now been locked in ice. This colossal stockpile of frozen ancient organic matter contains at least four times as much carbon as the sum total that has been released by human activity on the planet since the beginning of the industrial age. [4] As a significant portion is being stored in the form of methane - a super global warming gas that is a stunning 86 times more powerful than CO2 [5], scientists refer to this huge threat as a "sleeping giant". If major amounts thaw and release into the atmosphere, global warming would accelerate to the crossing of a tipping point - whereby the process becomes a runaway train and there is no longer hope for human intervention.

The Role of Methane in Earth's Mass Extinction Events -
Large scale methane release would speed all the worst impacts of climate disruption - severe drought, sea level rise, storms, flooding, wildfires, and forced migration of refugees - causing them to occur much sooner and on a more intense scale than currently projected. Some of that impact is described in an article published by the highly respected science journal Nature. [6] As if that level of devastation is not enough, it is even more disturbing is to contemplate where the crossing of this tipping point might lead. The prevailing opinion in the scientific community is that the release of super potent methane has played a central role in two of the most devastating mass extinction events in the history of earth - the End-Permian and the PETM. In the End-Permian, a mind-boggling 90 percent of all life forms on the planet were wiped out.

The scientific inquiry into the cause of this horrendous wipe-out has been portrayed in an under-publicized but extremely important documentary by the BBC entitled "The Day Earth Nearly Died". [7] The "short version" is that a tremendous, unprecedented series of volcanic eruptions in Siberia released enough carbon dioxide to drive earth's temperature up six degrees C (celsius). This radical increase then warmed the world's polar regions enough to thaw previously frozen methane. Evidence points to the heat from this super global warming gas driving temperatures up another five degrees C and causing the horrific wipe-out.

An Imperative Need to Communicate the Danger -
Politically neutral global organizations such as the World Bank and the International Energy Agency (IEA) are vehemently warning that the world is already on track for a five degree C warming by the end of the century. [8] Human-generated emissions are now pushing as much carbon pollution into the atmosphere as the Siberian volcanoes. This begs the obvious and deeply troubling question: Is the stage being set for another massive release of nature's own currently frozen carbon?

Methane plumes rising from the seafloor
Ominous Signs that Methane Thaw Is Already Starting -
As temperature increases are occuring more rapidly in the Arctic than anywhere on earth, the ice cover is now in a state of collapse from massive melting. It is widely known that in 2012 the record for ice loss was not just broken but shattered. As a result, that which has been called "permafrost" is no longer "permanent". On land, the tundra soil is progressively thawing - releasing both CO2 and methane. Key researchers are warning that an irreversible tipping point could come as soon as 15 or 20 years. [9] Even worse, it appears that as the upper layer of tundra thaws and exposure to sunlight is increased, a chemical reaction is increasing the speed: "....sunlight increases bacterial conversion of exposed soil carbon into carbon dioxide gas by at least 40 percent compared to carbon that remains in the dark." [10]

Vast amounts of of methane are also stored in frozen form in the seabeds. Whereas methane from the deep ocean oxidizes and is neutralized before it reaches the surface, the shallow seabeds along Arctic coastlines allow it to vent directly into the atmosphere. Russian researchers that have been monitoring the situation since the 1990s are now reporting "astonishment" at the vast scale of methane plumes being observed along the Siberian coast. Some of these plumes are a full kilometer wide - something never encountered before. [11] Other researchers from NASA are using aircraft to measure methane emissions entering the atmosphere and are reporting troubling increases. [12]

In other words, the date for a tipping point of no return has been moved up. The danger of climate disruption spinning out of human control is already staring us in the face.

A Breakthrough Documentary Finally Opening the Doors of Awareness -
It is imperative that this level of urgency be conveyed to government policymakers. For several years, a small but determined network of climate activists - backed by scientists engaged in cutting edge research - has been trying to sound the alarm about this catastrophic threat. Their efforts until now have largely been stymied by a combination of psychological denial regarding the severity of the danger, a seeming inability by the climate movement to look beyond the immediate battles regarding human-generated carbon emissions, and an almost paralyzing bureaucratic inertia within a scientific establishment failing to keep pace with the dizzying speed of climate disruption.

In this context, there has been a most welcome new development. Thanks to Thom Hartmann, Leila Conners and the Tree Media production group, a breakthrough documentary has been created which conveys this immense danger in no uncertain terms. [13] Solidly grounded on interviews with leading scientists and laced with visuals that drive the point home, "Last Hours" packs a big punch within the brief space of only 10 minutes.

This is the bullet point message on the home page of its website:
  • Underground, underwater and below the ice.
  • A time bomb is ticking.
  • Scientists are seeing the evidence.
  • Runaway climate change could be closer than we think. 
It is one of the first documentaries on climate that takes an unflinching look at the most colossal mass extinction events in the history of earth and points out how such devastation was related to severe climate change. It then looks at the tremendous level of climate disruption happening at the present time - which is occurring at a speed without any precedent in earth history, and refuses to shirk from using the same dreaded "e word" of extinction to describe the danger we face today.

In response to this invaluable program, there are now very positive signs that this recognition is finally taking place. In addition to the strong endorsements at the beginning of this commentary by Al Gore and Maggie Fox, the leaders of two other key climate groups add their voices:
"Last Hours is a captivating, extremely compelling appeal meant to awaken politicians and business leaders to take climate change action and stop runaway catastrophic climate change. Few films have managed to capture the sense of urgency as well as Last Hours. In the context of science telling us that emissions need to peak by 2015 and then come down, and with politicians doing little to reflect this urgency, this is a much needed asset for the climate movement." [14]
 Kumi Naidoo, International Director, Greenpeace International
"Last Hours is an alarming video that captures the state of emergency we face with climate disruption--yet at the same time we must recognize that there is real hope: the clean energy industry is rapidly growing, we are making headway in reducing carbon pollution, and by working together we can turn things around." [15]
— Michael Brune, Executive Director, Sierra Club
A Threat Comparable to Nuclear War -
The threat to our society represented by nuclear war can be grasped through the dramatic imagery of an atomic fireball, its devastation instantaneous. The threat from a climate catastrophe is no less sweeping, but actually more insidious as it would be a slow motion holocaust. Its impacts will gradually encircle humanity until the trap is sprung, at which time there is no escape.

Lying in wait in the Arctic is a volume of carbon that could easily push global temperatures so high as to threaten all life on earth. The three word phrase "irreversible tipping point" is easy to say but immensely challenging to truly comprehend. It is the point when colossal natural forces take over, when human civilization is rendered a helpless witness to its own destruction - a moment in time with supremely profound moral implications.

"The eyes of the future are looking back at us and they are praying for us to see beyond our own time. They are kneeling with hands clasped that we might act with restraint, that we might leave room for the life that is destined to come." 
— Terry Tempest Williams [16]
A Prayer from the Future -
The author has written a more in depth commentary on the existential threat presented by methane and the failure until now by our society to come to terms with it. [17] But it is ultimately a point where words fail to do justice. How can one describe the un-surpassable tragedy of the entire precious gift of life on this planet being decimated before our very eyes? In the words of ecological ethicist David Orr: “Climate destabilization, like nuclear war, has the potential to destroy all human life on Earth and in effect murder the future'......Willfully caused extinction is a crime that as yet has no name.”

It is now clear that the thaw and release of the "carbon bomb" in the Arctic has begun and is expanding. It is not just about the tar sands pipeline and human-generated carbon pollution, it is the monstrous beast in the Arctic that could be triggered by these pollutants. The climate movement - which has now spread world-wide - is the last and only hope for our society. Its passion must be brought to bear on this over-arching danger, its eyes fully opened if humanity is to even have a chance to act before it is too late.

The reaction of some of the leadership of this movement to "Last Hours" is a sign of hope. But that recognition must be rapidly disseminated and integrated by the grassroots base. There is a compelling need for wide circulation of this documentary. We must all break through our natural denial regarding a threat of this magnitude and find the strength to face it. In the words of a poem entitled "Invocation" by John Seed:
"Fill us with a sense of immense time so that our brief, flickering lives may truly reflect the work
of vast ages past and also the millions of years of evolution whose potential lies in our trembling hands." [18]

How Do We Act in the Face of Climate Chaos?

Guy McPherson


Guy R. McPherson is Professor Emeritus of Natural Resources
and 
Ecology & Evolutionary Biology at University of Arizona.
Below are some (slighly edited) extracts from a post at Guy
McPherson's website: 
summary and update on climate change.




The Warning

As described by the United Nations Advisory Group on Greenhouse Gases in 1990, temperature rise “beyond 1 degree C may elicit rapid, unpredictable and non-linear responses that could lead to extensive ecosystem damage”.

We’ve clearly triggered the types of positive feedbacks the United Nations warned about in 1990. Yet my colleagues and acquaintances think we can and will work our way out of this horrific mess with permaculture (which is not to denigrate permaculture, the principles of which are implemented at the mud hut). Reforestation doesn’t come close to overcoming combustion of fossil fuels, as pointed out in the 30 May 2013 issue of Nature Climate Change. Furthermore, forested ecosystems do not sequester additional carbon dioxide as it increases in the atmosphere, as disappointingly explained in the 6 August 2013 issue of New Phytologist.

Here’s the bottom line: On a planet 4 C hotter than baseline, all we can prepare for is human extinction (from Oliver Tickell’s 2008 synthesis in the Guardian).

John Davies concludes: “The world is probably at the start of a runaway Greenhouse Event which will end most human life on Earth before 2040.” He considers only atmospheric carbon dioxide concentration, not the many self-reinforcing feedback loops described below. 


Positive feedbacks
Positive feedbacks
Methane hydrates are bubbling out the Arctic Ocean (Science, March 2010). According to NASA’s CARVE project, these plumes were up to 150 kilometers across as of mid-July 2013. Whereas Malcolm Light’s 9 February 2012 forecast of extinction of all life on Earth by the middle of this century appears premature because his conclusion of exponential methane release during summer 2011 was based on data subsequently revised and smoothed by U.S. government agencies, subsequent information — most notably from NASA’s CARVE project — indicates the grave potential for catastrophic release of methane. Catastrophically rapid release of methane in the Arctic is further supported by Nafeez Ahmed’s thorough analysis in the 5 August 2013 issue of the Guardian as well as Natalia Shakhova’s 29 July 2013 interview with Nick Breeze (note the look of abject despair at the eight-minute mark).
Warm Atlantic water is defrosting the Arctic as it shoots through the Fram Strait (Science, January 2011).
Siberian methane vents have increased in size from less than a meter across in the summer of 2010 to about a kilometer across in 2011 (Tellus, February 2011)
Drought in the Amazon triggered the release of more carbon than the United States in 2010 (Science, February 2011). In addition, ongoing deforestation in the region is driving declines in precipitation at a rate much faster than long thought, as reported in the 19 July 2013 issue of Geophysical Research Letters.
Peat in the world’s boreal forests is decomposing at an astonishing rate (Nature Communications, November 2011)
Invasion of tall shrubs warms the soil, hence destabilizes the permafrost (Environmental Research Letters, March 2012)
Methane is being released from the Antarctic, too (Nature, August 2012). According to a paper in the 24 July 2013 issue of Scientific Reports, melt rate in the Antarctic has caught up to the Arctic.
Russian forest and bog fires are growing (NASA, August 2012), a phenomenon consequently apparent throughout the northern hemisphere (Nature Communications, July 2013). The New York Times reports hotter, drier conditions leading to huge fires in western North America as the “new normal” in their 1 July 2013 issue. A paper in the 22 July 2013 issue of the Proceedings of the National Academy of Sciences indicates boreal forests are burning at a rate exceeding that of the last 10,000 years.
Cracking of glaciers accelerates in the presence of increased carbon dioxide(Journal of Physics D: Applied Physics, October 2012)
The microbes have joined the party, too, according to a paper in the 23 February 2013 issue of New Scientist
Summer ice melt in Antarctica is at its highest level in a thousand years: Summer ice in the Antarctic is melting 10 times quicker than it was 600 years ago, with the most rapid melt occurring in the last 50 years (Nature Geoscience, April 2013). Although scientists have long expressed concern about the instability of the West Atlantic Ice Sheet (WAIS), a research paper published in the 28 August 2013 of Nature indicates the East Atlantic Ice Sheet (EAIS) has undergone rapid changes in the past five decades. The latter is the world’s largest ice sheet and was previously thought to be at little risk from climate change. But it has undergone rapid changes in the past five decades, signaling a potential threat to global sea levels. The EAIS holds enough water to raise sea levels more than 50 meters.
Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, according to a study accepted for publication in the Journal of Geophysical Research: Earth Surface (July 2013). It appears a Heinrich Event has been triggered in Greenland. Consider the description of such an event as provided by Robert Scribbler on 8 August 2013:
In a Heinrich Event, the melt forces eventually reach a tipping point. The warmer water has greatly softened the ice sheet. Floods of water flow out beneath the ice. Ice ponds grow into great lakes that may spill out both over top of the ice and underneath it. Large ice damns (sic) may or may not start to form. All through this time ice motion and melt is accelerating. Finally, a major tipping point is reached and in a single large event or ongoing series of such events, a massive surge of water and ice flush outward as the ice sheet enters an entirely chaotic state. Tsunamis of melt water rush out bearing their vast floatillas (sic) of ice burgs (sic), greatly contributing to sea level rise. And that’s when the weather really starts to get nasty. In the case of Greenland, the firing line for such events is the entire North Atlantic and, ultimately the Northern Hemisphere.
Breakdown of the thermohaline conveyor belt is happening in the Antarctic as well as the Arctic, thus leading to melting of Antarctic permafrost (Scientific Reports, July 2013)
Loss of Arctic sea ice is reducing the temperature gradient between the poles and the equator, thus causing the jet stream to slow and meander. One result is the creation of weather blocks such as the recent very high temperatures in Alaska. As aresultboreal peat dries and catches fire like a coal seam. The resulting soot enters the atmosphere to fall again, coating the ice surface elsewhere, thus reducing albedo and hastening the melting of ice. Each of these individual phenomena has been reported, albeit rarely, but to my knowledge the dots have not been connected beyond this space. The inability or unwillingness of the media to connect two dots is not surprising, and has been routinely reported (recently including here with respect to climate change and wildfires) (July 2013)
Earthquakes trigger methane release, and consequent warming of the planet triggers earthquakes, as reported by Sam Carana at Arctic-news (October 2013)
Arctic drilling was fast-tracked by the Obama administration during the summer of 2012
Supertankers are taking advantage of the slushy Arctic, demonstrating that every catastrophe represents a business opportunity, as pointed out by Professor of journalism Michael I. Niman and picked up by Truthout (ArtVoice, September 2013)
As nearly as I can distinguish, only the latter feedback process is reversible at a temporal scale relevant to our species. Once you pull the tab on the can of beer, there’s no keeping the carbon dioxide from bubbling up and out. These feedbacks are not additive, they are multiplicative. Now that we’ve entered the era of expensive oil, I can’t imagine we’ll voluntarily terminate the process of drilling for oil and gas in the Arctic (or anywhere else). Nor will we willingly forgo a few dollars by failing to take advantage of the long-sought Northwest Passage.

Robin Westenra provides an assessment of these positive feedbacks at Seemorerocks on 14 July 2013. It’s worth a look.


Earth-system scientist Clive Hamilton concludes in his April 2013 book Earthmasters that “without [atmospheric sulphates associated with industrial activity] … Earth would be an extra 1.1 C warmer.” In other words, collapse takes us directly to 2 C within a matter of weeks. 

Several other academic scientists have concluded, in the refereed journal literature no less, that the 2 C mark is essentially impossible (for example, see the review paper by Mark New and colleagues published in the 29 November 2010 issue of the Philosophical Transactions of the Royal Society A). 

The German Institute for International and Security Affairs concluded 2 June 2013 that a 2 C rise in global-average temperature is no longer feasible (and Spiegel agrees, finally, in their 7 June 2013 issue), while the ultra-conservative International Energy Agency concludes that, “coal will nearly overtake oil as the dominant energy source by 2017 … without a major shift away from coal, average global temperatures could rise by 6 degrees Celsius by 2050, leading to devastating climate change.”

At the 11:20 mark of this video, climate scientist Paul Beckwith indicates Earth could warm by 6 C within a decade. 

If you think his view is extreme, consider: 
  1. the 5 C rise in global-average temperature 55 million years ago during a span of 13 years (reported in the 1 October 2013 issue of Proceedings of the National Academy of Sciences); and also 
  2. the reconstruction of regional and global temperature for the past 11,300 years published in Science in March 2013. One result is shown in the above figure.

How Do We Act in the Face of Climate Chaos?

Below is a video of a recent presentation by Guy McPherson. 

Presentation by Guy McPherson in Boulder, Colorado on October 16, 2013.

Below are some extracts from the video, again slightly edited.

Malcolm Light in 2012 concluded, based on data from NOAA and NASA, that methane release had gone exponential and was leading to the demise of all life on Earth, not just human extinction, by the middle of the century.

So 3.5 C to 4 C is almost certainly a death sentence for all human beings on the planet, not because it'll be a warmer planet, but because the warming of the planet will remove all habitat for human beings. Ultimately we're human animals like other animals, we need habitat to survive.

Changes we see in three or four decades happen as a result of what we do today. There's a huge lag between our actions today in the consequences down the road in terms of the Earth's planetary systems.

Without plankton in the ocean, there goes roughly half the global food supply. The ability to lose land plants is growing rapidly and there goes the other half for the food supply for human beings. If we have up to 5 C by 2050, that'll certainly do the trick.

Why is this happening? It's civilization that drove us into population overshoot. We cannot go back anymore since 1939, since we invented nuclear armageddon. There's no going back. If we ceased the set of living arrangements at this point, the world's 400 or so nuclear power plants melt down catastrophically and we're all dead in a month. We cannot terminate industrial civilization until we decommission all nuclear power plants. It takes at least 20 years to decommission a nuclear power plant.

The bad news is that means that the world's four hundred or so nuclear power plants meltdown catastrophically in a short period of time. Fukushima represent a major threat to humanity. If they fail in moving the spent fuel rods next month, according to nuclear researcher Christina Consola, if one of those MOX fuel rods is exposed to the air, one of the 1565, it will kill 2.89 billion people on the planet in a matter of weeks, so nuclear catastrophe is right there on the horizon. 

People ask me: Why are you presenting this horrible information?

Action is the antidote to despair even if the action is hopeless. When a medical doctor knows that somebody has cancer, it's malpractice if they don't tell that. So I'm doing that. I think Bill McKibben and James Hansen and a whole bunch of climate scientists are guilty of malpractice. Because they know what I know. Almost every politician in the country knows what I know. All the leaders of the big banks know what I know. And they're lying to us.

I'm just presenting the information from other scientists here. I'm trying to the widest extent possible not to infuse my opinion in the situation. It's John Davies who on September 20, 2013, taking into account only carbon dioxide, says there will be few people left on the planet by 2040. It's Malcolm Light, writing in February 2012, who assesses the methane situation. And so on.

Yes, I agree with them, and that agreement is illustrated by me showing you that information.

I promote resistance against this omnicidal culture, not in the hope that it will save our species, but in the hope that it will save other species. Because as E.O. Wilson, biologist at Harvard, points out, it only takes 10 million years after a great extinction event, before you have a blossoming full rich planet again. That's what we're working toward. We're saving habitat for other species at this point.

HISTORIC KILLER METHANE COULD ERUPT FROM ARCTIC

by Gary Houser



FOREWORD AND ENDORSEMENT
by Peter Wadhams


Prof. Peter Wadhams, measuring the Arctic sea
ice's thickness with the help of a submarine
"The world is entering one of the most dangerous periods in its history. The failure of international efforts to reduce carbon emissions has led to a carbon dioxide level in the atmosphere which guarantees a serious level of global warming during coming decades, enough to compromise the life support system of the planet. On top of the carbon dioxide threat, a further greenhouse gas threat looms - the prospect of large releases of methane from offshore sediments on Arctic continental shelves. This is an outcome of the retreat of sea ice which allows coastal waters to warm up and degrade the offshore permafrost. This threat, all too clear in the photographic evidence of methane emissions obtained by US-Russian expeditions, could greatly accelerate global warming and add further enormous costs to the planet's burden. Only immediate drastic action can avert a catastrophic worsening of our climatic plight. I support this commentary by Gary Houser."

HISTORIC KILLER METHANE COULD ERUPT FROM ARCTIC:
The Severity of the Threat and the Tragic Moral Failure to Address It

“Over hundreds of millennia, Arctic permafrost soils have accumulated vast stores of organic carbon - an estimated 1,400 to 1,850 billion metric tons of it.... In comparison, about 350 billion metric tons of carbon have been emitted from all fossil-fuel combustion and human activities since 1850.”
- from NASA news release "Is a Sleeping Climate Giant Stirring in the Arctic? [1]

“Climate destabilization, like nuclear war, has the potential to destroy all human life on Earth and in effect murder the future'......Willfully caused extinction is a crime that as yet has no name.”
- ecological ethicist David Orr [2]

“It's not clear that civilization could survive that extreme of a climate change.”
- world renowned climate scientist James Hansen, referring to the radical increase in global warming that would result from a major release of super greenhouse gas methane [3]

PART ONE -

All who might dismiss this title as “exaggeration” and the opening photo as “alarmism” owe it to their children and grandchildren and the future of humanity to read on. Large scale thawing and release of previously frozen methane gas has wiped out great swaths of life before and is quite capable of doing so again. Warming from carbon emissions is now unleashing Arctic deposits of this super greenhouse gas - an awesome and truly frightening force - and threatens to initiate a chain reaction that could well be unstoppable once started.

This commentary does not dwell on “doomsday” rhetoric. But humanity is teetering much closer to oblivion than what has been “getting through” in the shallow coverage offered by mass media, and there is a moral imperative to issue a warning. Mass extinction - especially self-imposed - is not a “pretty” concept and the use of a few graphic images is necessary to both convey a reality that may be forcing itself upon us and to penetrate the shield of denial. The voices of scientists pressing on this front deserve to be amplified. Their observations and concerns are presented to the reader, who is invited to evaluate whether any “alarm” is justified. Humanity is standing on the very edge of a cliff, and if we fall off it will be a one way ticket to Hell.

Despite the looming shadow cast by this danger, it has yet to make its way into public consciousness. Even the world-wide environmental movement has continued to focus on human-generated emission of global warming gases and has not grasped the dire implications of the accelerated catastrophe which could ensue if nature's own stockpile becomes activated - an immense storehouse containing far more carbon than humans have generated since the onset of the industrial age. Though the sweeping scale of this existential threat combined with its potential irreversibility - once triggered - may be leading to psychological denial, the reality of the danger compels humanity to take all precaution and spare no expense in both understanding and reducing it. Yet the response so far points to an unspeakably tragic moral collapse. Every single segment of our society that should be either sounding the alarm or taking definitive action to prevent this global catastrophe is presently looking the other way. This commentary examines such failure in Part Two, but first explores the nature and magnitude of the danger itself.

Geological Record Points to the Destructive Power of Methane -
Although carbon dioxide persists much longer in the atmosphere, the Intergovernmental Panel on Climate Change (IPCC) states that methane is a full 72 times more powerful during its first 20 years. [4] It is the prevailing view of the scientific community that earlier major releases of this gas resulted in the most catastrophic wipe-outs of life in planetary history. Two critically important British documentaries explore the scientific inquiry linking methane to both the Permian [5] and PETM [6] mass extinction events.

Volcanic eruption: Mount Pinatubo (1991)
Etched into ancient layers of rock is the record of the Permian extinction event - the most complete decimation of life known to science. Searches for fossilized clues of living organisms reveal a stunningly empty slate. [7] It is believed that a staggering 90% of the life forms on earth simply disappeared. Scientific opinion - also based on the geologic record - is that a tremendous series of volcanic eruptions in Siberia released enough carbon dioxide to drive earth's temperature up five degrees C (centigrade). This radical increase then warmed the world's oceans enough to thaw previously frozen methane. Evidence points to the heat from this super global warming gas driving temperatures up another five degrees C and causing the horrific wipe-out.

How Severe is the Current Threat?
Numerous, quite authoritative and politically neutral sources (such as the World Bank and the International Energy Agency (IEA) are now in agreement that if global carbon emissions are not dramatically reduced very quickly, the planet will be seeing temperature increases of five degrees C or more by the latter part of this century. [8] Such a human-generated increase could very well take the place of the volcanic eruptions in Siberia, and could set the stage for a potential mass release of ancient methane.

How the Arctic Is Playing a Key Role -
The vastness of the carbon deposit which could be released from the Arctic is mind-boggling, dwarfing the total thus far generated by humans. Nowhere on earth are temperatures rising as quickly. NASA describes the role of the Arctic in driving climate disruption: "The Arctic is critical to understanding global climate. Climate change is already happening in the Arctic, faster than its ecosystems can adapt. Looking at the Arctic is like looking at the canary in the coal mine for the entire Earth system." [9]

Arctic ice, August 19, 2007, by Ash from Flicker
Last year, Arctic ice coverage was reduced to its lowest level in recorded history. Even worse, this massive meltdown appears to be developing an unstoppable momentum through what scientists are calling a “death spiral” - where open water caused by accelerated melting is now absorbing additional solar heat and setting into motion even more melting. [10]


Methane plumes rising from the seafloor
Ira Leifer - methane specialist at the Univ. of California and co-author of a paper describing evidence that Arctic methane is venting into the atmosphere [11] - describes the unique factor represented by the shallow seas in that region:
“The East Siberian Arctic Shelf is vast and shallow..... Methane in a shallow sea can make its way to the atmosphere without dissolving significantly and being eaten by microbes.......These vast methane hydrate deposits are a risk and a great concern because as the oceans warm, they will release their methane and it will make its way to the atmosphere.” [12]
Super Greenhouse Gas Beginning to Thaw and Vent to Atmosphere -
Researchers in the field are now bringing back eyewitness reports of plumes of methane bubbles rising to the surface on a scale they have never seen before. Igor Semiletov - who has pursued this issue for 15 years - reported astonishment regarding the observations made during a joint U.S.-Soviet expedition to the East Siberian Arctic Shelf (ESAS) in 2011:
“We carried out checks at about 115 stationary points and discovered methane fields of a fantastic scale - I think on a scale not seen before. Some of the plumes were a kilometer or more wide and the emissions went directly into the atmosphere - the concentration was a hundred times higher than normal.” [13]
In an ominous paper based on the findings of that expedition, Russian scientists elaborated further on the unprecedented nature of the observed plumes:
"In some oceanographic sections, a number of plumes over 100 meters in diameter were joined into a multirooted enormous plume over 1000 meters in diameter which exceeds greatly the dimensions of plumes registered formerly in the Sea of Okhotsk and in other areas of the World Ocean where the typical plume diameter usually varied from a few meters to tens of meters." [14] 
This unsettling scale of plume activity is reflected in the following chart:
From: The Degradation of Submarine Permafrost and the Destruction of Hydrates on the Shelf of East Arctic Seas as a Potential
Cause of the “Methane Catastrophe”: Some Results of Integrated Studies in 2011, V. I. Sergienko et al., in Oceanology (Sept. 2012)
NASA has conducted measurements of methane over the Arctic Sea via airplane. According to researcher Eric Kort:
“When we flew over areas were the sea ice had melted, or where there were cracks in the ice, we saw the methane level increase...... Our observations really point to the ocean surface as the source, which was not what we had expected.....The association with sea ice makes this methane source likely to be sensitive to changing Arctic ice cover and dynamics, providing an unrecognized feedback process in the global atmosphere-climate system.” [15]
Methane Emissions from Seabeds Paralleled by Land-Based Permafrost Releasing Carbon -
Observations of increased methane emitting from the shallow Arctic seabeds are being mirrored by similar observations on land. The rate at which previously frozen carbon is releasing from land permafrost is now accelerating :
“Thawing permafrost is emitting more climate-heating carbon faster than previously realized. Scientists have now learned that when the ancient carbon locked in the ice thaws and is exposed to sunlight, it turns into carbon dioxide 40 percent faster. 'This really changes the trajectory of the debate over when and how much carbon will be released as permafrost thaws due to ever warmer temperatures in the Arctic.” [16]
From: NOAA 2012 RUSALCA Expedition, RAS-NOAA. Wrangel Island, Alaska in early morning (Photo credit: Kate Stafford)
From the same NASA news release mentioned above:
“What they're finding, Miller said, is both amazing and potentially troubling. "Some of the methane and carbon dioxide concentrations we've measured have been large, and we're seeing very different patterns from what models suggest. We saw large, regional-scale episodic bursts of higher-than-normal carbon dioxide and methane in interior Alaska and across the North Slope during the spring thaw, and they lasted until after the fall refreeze.” [17]
A major report by the United Nations Environment Programme (UNEP) summarizes this parallel situation:
“According to the report, Arctic and alpine air temperatures are expected to increase at roughly twice the global rate, and climate projections indicate substantial loss of permafrost by 2100. A global temperature increase of 3 degrees Celsius means a 6 degrees Celsius increase in the Arctic, resulting in an irreversible loss of anywhere between 30 to 85 percent of near-surface permafrost.” [18]
Ground-breaking Study Quantifies Global Damage That Could Result from Major Methane Release -
Authoritative science journal Nature recently published an article describing the staggering economic impact that would be caused by a major release of methane. Top British ice scientist Peter Wadhams collaborated with economic modelers to apply to Arctic methane the same modeling used in the highly respected Stern Report to quantify the damage to the world economy which would result from human-generated greenhouse gases. They issue a stunning warning that the damage could be comparable to the total value of the entire global economy last year:
“We calculate that the costs of a melting Arctic will be huge, because the region is pivotal to the functioning of Earth systems such as oceans and the climate. The release of methane from thawing permafrost beneath the East Siberian Sea, off northern Russia, alone comes with an average global price tag of $60 trillion in the absence of mitigating action - a figure comparable to the size of the world economy in 2012 (about $70 trillion).” [19]
How Close Are We to a Major Release?
It is not possible to predict precisely when such a line could be crossed. But Arctic scientists are indeed reporting that the conditions necessary for such a “breakout” are now in fact lining up. These include a vast storehouse of frozen methane, shallow seas that allow the gas to reach the surface, a massive loss of ice that only seems destined to accelerate, and rapid warming of temperature. Shallow seas also warm faster than deep ocean. Not only is the Arctic the most rapidly warming region on earth, but the East Siberian Arctic Shelf is the most rapidly warming segment of that region. According to Natalia Shakhova of the Russian team:"Observed warming on the ESAS (March-April-May)..... is the strongest in the entire Arctic and the region is now 5°C warmer compared with average springtime temperature registered during the 20th century." [20]

This level of radical warming is already approaching that generated by the volcanic eruptions preceding the Permian mass extinction. The fact that major concern is increasing is reflected in the striking development that no less than 21 Russian scientists all agreed that circumstances were approaching a point when the words "potential catastrophe" should even be included in the title of their paper: "The Degradation of Submarine Permafrost and the Destruction of Hydrates on the Shelf of East Arctic Seas as a Potential Cause of the 'Methane Catastrophe' ." Here is what they say in the paper itself:
"Under the conditions of the observed abnormal warming of the East Siberian shelf, the acceleration of thawing of the upper layer of submarine permafrost and an increase of bottom erosion are inevitable ...... The emission of methane in several areas of the ESS is massive to the extent that growth in the methane concentrations in the atmosphere to values capable of causing a considerable and even catastrophic warming on the Earth is possible." [21]

When one looks at the history of extremely careful and cautious use of language by the Russian research teams, this escalation in terminology is even more remarkable.

When such conditions are forming and carry consequences that could bring down our civilization, it is clear that humanity is already entering into an emergency state. In his article “Methane Hydrates: A Volatile Time Bomb in the Arctic”, Australian climate scientist Carlos Duarte states the following :
“Even moderate (a few degrees C) warming of the overlying waters may change the state of methane from hydrates to methane gas, which would be released to the atmosphere......If the state shift is abrupt it may lead to a massive release ....which could cause a climatic jump several-fold greater than the accumulated effect of anthropogenic activity.” [22]
According to the world-renowned climate expert who has done more than any other to alert world attention to the crisis - James Hansen:
“Our greatest concern is that loss of Arctic sea ice creates a grave threat of passing two other tipping points - the potential instability of the Greenland ice sheet and methane hydrates. These latter two tipping points would have consequences that are practically irreversible on time scales of relevance to humanity.” [23]
“We are in a planetary emergency.” [24]
Runaway Methane Feedback: The End of Life as We Know It? -
A large methane release would in itself be a catastrophic event - as described in the Nature article. But the threat from methane could yet escalate to another level of existential nightmare. Ira Leifer comments on what is called a “runaway feedback”:
“A runaway feedback effect would be where methane comes out of the ocean into the atmosphere leading to warming, leading to warmer oceans and more methane coming out, causing an accelerated rate of warming in what one could describe as a runaway train..... The amount of methane that’s trapped under the permafrost and in hydrates in the Arctic areas is so large that if it was rapidly released it could radically change the atmosphere in a way that would probably be unstoppable and inimicable to human life." [25]

The British expert with over 30 years of experience studying Arctic ice issues - Peter Wadhams of Cambridge University - was asked by the author to respond to the question “Are there any natural “brakes” in the Arctic ecosystem that would prevent a large methane release from escalating into an unstoppable runaway reaction?” His response:
“There are no brakes. The methane release itself results as a positive feedback from another warming-generated process, the retreat of summer sea ice. So we have global warming causing summer sea ice retreat causing offshore permafrost thawing causing methane release causing a big instant warming boost causing endless other positive feedbacks.” [26]
Several cutting edge observations by scientists are presented in a documentary co-produced by this writer (available free on YouTube [27] ), featuring the immensely respected James Hansen. In reference to the radical temperature increase that would be caused by a major release of methane, Hansen warns that “it's not clear that civilization could survive that extreme of a climate change.” [28]

Time is running out - by Louis Afonso
Rising sea levels will indeed flood many of the coastal cities of the world and their residents will be confronted with great chaos and strife. Their populations will be forced to migrate inland, but that in itself does not represent a collapse of civilization. The kind of radical heat brought on by a major methane release will not permit any escape. Life cannot be sustained without adequate food and water, yet such capacity would be severely impacted.

Time is not on our side. If human society does not recognize the danger and take concerted action to prevent it, colossal natural forces are simply going to run their course. Circumstances would disintegrate in a manner that humanity could no longer control. Yet in the precious time we have to act before such a point is reached, our society is utterly failing to do so. In Part Two, a hard look is taken at this failure at many levels - in the hope that such can be reversed before time runs out.

PART TWO -

1946 famine in China
The Barriers Blocking Adequate Warning and Understanding -
The impact of climate disruption on humanity has been called an "inconvenient truth". It has been described as causing extreme weather, giant storms, record flooding, expanded drought, and rampant wild fires. But all such descriptions utterly fail to convey the full scope of the horrendous wipe-out now looming over us all. "Connecting the dots" reveals a threat of such sweeping magnitude to our entire future existence that it is very difficult to accept into our consciousness. A psychological defense mechanism within us all drives an extremely potent internal barrier.

Chief among the external barriers is the inordinate power of the fossil fuel industry. Our government - which is supposed to act in defense of the public interest - is not taking strong enough action because of the influence wielded by the wealthiest corporations on earth. It is no secret that the right wing extremist Tea Party was bankrolled by this industry in order to push the Republican stance into an obstructionist position on climate. It has also placed massive funding behind a widespread media blitz attacking the credibility of the science community. The strong pre-existing inclination toward denial has only been exacerbated by the disinformation campaign of the carbon pollution profiteers. But the failure to provide warning is more insidious when it can be observed even among those elements of society one would assume are tasked with this responsibility.

The Failure of Mass Media -
The U.S. mass media in particular has failed to move beyond superficial slogans and engage in a penetrating investigation into the depth of the climate crisis. To not even raise the climate issue during the presidential campaign was outrageous and indefensible. Investigative reporters should be intensively pursuing the Arctic methane story and bringing it to the attention of the prime time news outlets. They are not.

One of the greatest challenges regarding the climate emergency is that public consciousness must shift BEFORE a tipping point is reached whereby it is no longer possible to reverse course. If this shift fails to happen in time, humanity would likely be placed in a helpless position. One of the great benefits offered by the video medium is that a fictional event can be so vividly simulated on screen as to make the viewer feel like he or she is truly "experiencing" it. In 1983, there was a major television event called "The Day After". In prime time, heavily publicized in advance, and using well known "Hollywood" actors, a national TV audience of over 100 million "experienced" the horror that would be entailed in a nuclear holocaust. [1]

The nation's leading policymakers - including even the president - were profoundly affected. In former President Reagan's autobiography, he wrote that the film was "very effective and left me greatly depressed," and that it actually changed his mind about the prevailing policy on nuclear war. [2] Many give credit to that "experience" as being the turning point when public opinion turned solidly against the continuation of the nuclear arms race between the U.S. and the Soviet Union. Four years after the broadcast, a nuclear treaty was signed with the Soviet Union. A brief clip from that film serves as an example of the power of the video medium to simulate disaster: [3]

Nagasaki, Japonia, 9 august 1945
This time the threat is not from the immediate destruction of an atomic fireball but rather a slow motion holocaust - a gradual but inexorable decimation of the conditions for life on this planet. Gathering force step by step, it would be even more insidious as the momentum would build until the inescapable trap is finally sprung.

Climate breakdown is not quite as "black and white" as a nuclear explosion, but with good preparation and script-writing it can be portrayed. The TV networks could be developing a film comparable to "The Day After". They could be dedicating comparable resources to another major television event with the goal of making a global climate catastrophe more tangible and more "real" to another large national audience. They are not.

How the Scientific Community Is Falling Short -
The scientific community of course deserves much credit for the huge amount of research and education it has provided on climate. But so much institutional attention has been focused on the issue of human-generated global warming (from carbon dioxide emissions), that it has been extremely slow to make the shift toward recognizing the tremendous threat presented by the vast stockpile of nature's own greenhouse gases being stored in the polar regions.

There is also a structural reason that the scientific community is failing to communicate to policymakers how dire our situation has actually become. The primary documents produced by the world's scientists which are supposed to guide government policy decisions are the periodic reports of the Intergovernmental Panel on Climate Change (IPCC). But these reports are being compromised by two severe problems. One is the very slow and un-necessarily cumbersome internal process by which new scientific information is incorporated. There can be a three year lag time before cutting edge science is integrated into mainstream literature.

A classic example is the tremendous threat from thawing Arctic permafrost (both sea-based and land-based). As most major revelations have come within the last three years, initial drafts indicate that the new IPCC report - due to be released later this year - is not even going to address this issue in any meaningful way. Some Arctic scientists are speaking up for its inclusion, as reflected in a document prepared for the United Nations Environment Programme (UNEP):
"The potential hazards of carbon dioxide and methane emissions from warming permafrost are not included in current climate-prediction models. 'This report seeks to communicate to climate treaty negotiators, policy makers, and the general public the implications of continuing to ignore the challenges of warming permafrost,' said U.N. Under-Secretary General and UNEP Executive Director Achim Steiner.....'Anthropogenic emissions targets in the climate change treaty need to account for these emissions or we risk overshooting the 2 degrees Celsius maximum warming target,' Schaefer added." [4]
IPCC meeting
At a time of approaching tipping points, such lag time is exceedingly dangerous. Making matters even worse is the second major structural problem. Government political entities have actually been given the power to review and "approve" the science that is released to policymakers and the public. This has created an opening for vested interests to pressure their governments to refrain from language conveying urgency, often resulting in excessively watered down statements and overly conservative predictions. Another classic example: The IPCC projected that the all-important Arctic ice collapse would not occur until the year 2100, and yet such is already pressing upon us.

British climate feedback expert David Wasdell decries what he calls a "grossly inappropriate" process:
The initial language of an IPCC report "has to be passed through a conference of the agencies of the governments, and if they don't like it because it affects their particular country .... they will veto it. So what comes out - particularly in the Summary for Policymakers - is that which is 'acceptable' ...... from science that is about six years out of date, and that becomes the basis for negotiation and decision-making. It is grossly inappropriate....... There are many pressures ..... not least the enormous profits that continue to be made from fossil fuels."
A critically important and eloquent critique of the IPCC process is available in a video interview with Wasdell. [5]

A stunning real-life example of such suppression of science occurred during preparation of the last report in 2007. According to the Washington Post, the U.S. actually removed language calling for emission reduction:
"Some sections of a grim scientific assessment of the impact of global warming on human, animal and plant life issued in Brussels yesterday were softened at the insistence of officials from China and the United States ...... U.S. negotiators managed to eliminate language in one section that called for cuts in greenhouse gas emissions." [6]
It is frightening that an imminent danger of such sweeping magnitude is in the process of being completely ignored in the new IPCC report to the world. If left uncorrected, this report would not be updated for six more years and policymakers would continue to not be properly informed during the only window of time that may be available to avert catastrophe. There should be a hue and cry from the entire scientific community to not allow this. Presently, it is failing to do so.

It is also true that the scientific tradition of seeking absolute "proof" - normally a good thing - in this case works against the best interest of society. By the time there is "absolute" proof that a major methane release or even a "runaway" situation is imminent, it will very likely be too late to stop it.

A much more complete statement by this writer addressing the failure of the scientific community to provide adequate warning is available here. [7] The full weight of the world scientific community should be placed behind an emphatic warning based on the precautionary principle and a moral imperative to act preventatively NOW before a tipping point is crossed.

The Failure of the Religious Community -
The failure of the multi-faith religious community is especially grievous, as it is the segment of society which has willfully taken on the responsibility of providing moral guidance. At a time when humanity is facing a holocaust that can only be compared to all out nuclear war in its magnitude, it should be shouting to the world that there is an existential emergency. At the peak of the nuclear arms race in the early 1980s, the religious community did speak out and many leaders achieved impact through dramatic acts of nonviolent civil disobedience at nuclear weapon facilities. But apart from the actions of some courageous individuals, today's leaders seem only willing to issue proclamations and only a tiny number have joined the protests in the streets.

At precisely the time when a powerful voice like that of the prophet Isaiah in the Judeo-Christian tradition is needed, the religious community as a whole has been complicit in a terrible and indefensible silence while this catastrophe approaches. The definition of sin is "a transgression of a religious or moral law, especially when deliberate." [8] How can it be said that this definition does not fit such complicity and overwhelmingly tragic moral failure in the face of a possible wipe-out of God's Creation? The magnificence of life - and how it stands to be decimated by such catastrophe - is depicted with breathtaking cinematography in a film entitled "Home"[9]

Jesus wept - painting by Erik Hollander

"Though seeing, they do not see;
though hearing, they do not hear or understand....
For this people's heart has become calloused;
They hardly hear with their ears,
And they have closed their eyes."
- words of Jesus in Matthew 13

Exclusive Focus on Tar Sands Oil Blocking Awareness of Other Imminent and Equally Dangerous Threats -
The climate movement has come a long way. A major coalition has formed in opposition to the tar sands pipeline, and many good-hearted people are giving their all - including nonviolent civil disobedience - in spirited resistance. This writer is a part of that campaign. 350.org in particular deserves praise for becoming the "conscience" of this struggle. The money power of the industry has forced a pitched battle, and it is quite understandable that such a protracted struggle consumes resources.

However, a quite serious problem has emerged from the current single-minded focus on tar sands. The tremendous threat presented by the Arctic meltdown is simply being shunted aside. Bill McKibben - spokesperson for 350.org - reminds over and over in his writings that the laws of physics cannot be stopped. Those same laws are now dismantling the Arctic ice cover, a drastic change that will lead to drastic consequences. McKibben acknowledges such in communications with this writer, yet the posted material of 350.org does not even mention this gathering emergency - let alone issue any kind of warning to the public. It is entirely correct that "doing the math" requires that remaining fossil fuel reserves be left in the ground. But presenting that as the single focus of concern is glaringly and even dangerously incomplete. The "front line" in terms of the most imminent and unstoppable tipping point staring humanity in the face is the threat of releasing nature's own vast stockpile of global warming gases in the Arctic, and yet the very group being looked to for leadership on the climate issue has been inexplicably silent.

Though some success has been gained in "breaking through" to media coverage on tar sands, this does not make the other threats go away. The frightening consequences of climate disruption are unfortunately not lining up in single file. As such, humanity is now faced with yet another "inconvenient truth". The climate coalition - and most particularly 350.org as a leading force - has a responsibility in this situation to convey all relevant facts to both the public and policymakers, and it is presently failing to do so.

The Most Colossal Moral Tragedy -

"The eyes of the future are looking back at us and they are praying for us to see beyond our own time."
- Terry Tempest Williams

Children sing out for their future in this gut-wrenching music video. [10] The region of earth now facing the most imminent "tipping point" is the Arctic. It is an emergency situation requiring immediate prioritization and preventative action. No scientist can predict an exact date when a large methane release or unstoppable methane "runaway" may be triggered. But there is also no credible scientist who can deny that the conditions for such are now forming. Some advocate that geo-engineering research be stepped up to prepare for a last gasp effort at regaining control. But opposition to even such research is increasing the likelihood that humanity may well run out of options.

We are sliding closer and closer to the brink of a methane-heated hell on earth. If temperatures shoot up 10 degrees C or more (well within current projections), we could well find ourselves involuntarily tethered to an unstoppable "doomsday machine" leading to a parched wasteland facing a ghastly wipe-out of life comparable to what happened 250 million years ago. It would become the greatest tragedy imaginable not only because of the scale of destruction but also because there was a real opportunity to prevent it and yet those who tried to issue a warning were ignored. Those engaged in a life or death struggle on a ravaged planet would not look back kindly on this unspeakable failure to address the unmistakable warning signs raging in our faces.

It would be easy to place all blame on those blindly seeking profit from fossil fuels. But the other segments of our society - those that supposedly existed to provide clear thinking and act as a counterweight to the forces of raw greed - would also have failed. That is why it would qualify as the most colossal moral tragedy in human history. In the final analysis, all words fail to do justice. What words could possibly convey the moral atrocity of taking this majestic earth and sacred gift of abundant life and rendering it dessicated and lifeless? As David Orr points out, there is no language for self-imposed, "willfully caused" extinction. Though perhaps these words from Martin Luther King and the poet Percy Bysshe Shelley grope in the right direction?

"Over the bleached bones and jumbled residues of numerous civilizations are written the pathetic words, Too late."
- Martin Luther King [11]

"And on the pedestal these words appear:
'My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!'

Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away."
- from Shelley's poem "Ozymandias"

ABOUT THE AUTHOR

Gary Houser is a long time public interest advocate and writer based in Ohio in the U.S.  He is presently organizing support for the 50 megawatt Turning Point solar farm - set to become the largest solar farm in the eastern part of the country, and symbolically located on a former strip mine in coal country.  But his primary focus is raising awareness about the great danger of super greenhouse gas methane, its likely role in the most deadly mass extinction event in earth's history, and the potential for human-generated carbon pollution to unleash vast quantities currently stored in frozen form in the Arctic - a release that could escalate climate disruption to a level beyond human control. He is the associate producer of a short, grassroots-style documentary on the topic available on YouTube ("Arctic Methane: Why the Sea Ice Matters"), seeking to use it as a catalyst to spark a fully funded program for broadcast on a major public TV venue such as PBS in the U.S. and the BBC in the UK. He is also seeking a Congressional hearing, and working to form a co-operative network of methane activists in the U.S. - including the producers of another documentary just released entitled "Last Hours". Recently becoming a dad has only increased his sense of urgency and determination to work on behalf of future generations.
