Albedo change in the Arctic threatens to cause runaway global warming

Mark Flanner et al. calculated in 2011 that snow and ice on the Northern Hemisphere had a combined cooling effect of 3.3 Watts per square meter (of which 2 W/m² relates to the snow cover on land and 1.3 W/m² to the sea ice).

This cooling effect is diminishing rapidly, as temperatures rise and snow and ice cover declines. Snow and ice on the Northern Hemisphere had already declined substantially over the years and was reflecting 0.45 watts less energy per square meter in 2011 than it did in 1979 (Flanner, 2011).

As discussed in Albedo change in the Arctic, Professor Peter Wadhams calculates that the loss of the Arctic sea ice cooling effect alone can be compared to the net global warming caused by people's emissions (1.66 W/m², IPCC, 2007b).

The exponential trends added by Wipneus to PIOMAS Arctic sea ice volume data show that the Arctic Ocean looks set to be ice-free from 2015 onwards for the period from August through to October, while July and November look set to follow from 2017, respectively 2018 onwards with June following closely thereafter. In other words, we could soon face an Arctic Ocean that is ice-free for half the year.

Snow cover on land takes up an even larger area than sea ice. The chart below illustrates the decline of snow cover on land in the Northern Hemisphere (without Greenland) for the month June.



What trends could fit these data? On the image below, I've added trendlines and I encourage others to come up with better ones.

Clearly, a lot of snow and ice looks set to disappear over the next few years. Note that what happens in winter doesn't matter as much, as little sunlight reaches the Arctic in winter. What matters most is how much sunlight is reflected when insolation in the Arctic is high. Insolation during the months June and July is higher in the Arctic than anywhere else on Earth, as shown on the image below, by Pidwirny (2006).



While Greenland remains extensively covered with snow and ice, the reflectivity of its cover shows rapid decline, as illustrated by the image below. The July data since 2000, from the meltfactor blog with projection in red added by Sam Carana, suggest a exponential fall in reflectivity that looks set to go into freefall next year.

Albedo: wikipedia.org/wiki/Albedo

A drop of as little as 1% in Earth’s albedo corresponds with a warming roughly equal to the effect of doubling the amount of carbon dioxide in the atmosphere, which would cause Earth to retain an additional 3.4 watts of energy for every square meter of surface area (NASA, 2005; Flanner et al., 2011).

Combined, the snow line retreat, loss of sea ice and decline of Greenland's reflectivity constitute a huge loss of summer cooling in the Arctic.

As a result, summer temperatures in the Arctic look set to rise rapidly over the next few years, threatening to unleash massive amounts of methane from sediments below shallow waters of the Arctic Ocean, spiraling Earth into runaway global warming.

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."

Dr. Peter Wadhams [ from his bio: Professor of Ocean Physics, Cambridge University in the UK, leads the Polar Ocean Physics group studying the effects of global warming on sea ice, icebergs and the polar oceans. This involves work in the Arctic and Antarctic from nuclear submarines, autonomous underwater vehicles (AUVs), icebreakers, aircraft and drifting ice camps. He has been studying polar ice issues for 43 years and has led over 40 polar field expeditions. ]

HISTORIC KILLER METHANE COULD ERUPT FROM ARCTIC:
The Severity of the Threat and the Tragic Moral Failure to Address It
by Gary Houser
{Disclaimer: The threat of climate catastrophe is not a "pretty" concept. As impacts begin to
intensify, there will be much real suffering and some photos included in this commentary
are representative of this reality and the danger forcing itself upon us. They are intended
for grown-ups, whose most important responsibility is to protect the future of their children.

“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."

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

Who stands up for the children? - screenshot from children against climate change protest video
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."

The Greatest War Ever

Introduction - Highest Urgency and Priority for Australia

Aaron Franklin
By Aaron Franklin

Hello everyone,

I hope this report is helpful in understanding the current very serious situation. Its an attempt to present it in a way that's accessible to all.

There should be no other priorities until this is dealt with.

Every one should acquaint themselves with the Arctic Methane Emergency Group (AMEG) and its Strategic plan, at:  http://a-m-e-g.blogspot.com/2012/12/ameg-strategic-plan.html

Lots of good up to date information can be found at http://arctic-news.blogspot.com/ , most of the reports there should be compulsory reading for all.

For Australia, as no other world governments appear to be taking notice or action yet, we should lead by example.

The first and most urgent actions we can do are:
  • Get all appropriate Naval vessels en route to the north Pacific and our military engineers preparing seawater mist spraying equipment to be flown to meet them when they get there to meet the dawning Arctic spring. This is for whats called "cloud brightening" and has been trialed and proven already. This produces bright white clouds that reflect sunlight back into space, rather than heating seawater.

    Cooling the waters in the Bering strait region before they invade the arctic basin, and melt the East Siberian Ice Shelf Icepack, is probably achievable with our resources.

    With likely a similar amount of methane, from all winter seafloor hydrates fizzing, trapped under the ESAS sea-ice as is in the Earth's atmosphere right now, this would be a major victory.

    AMEG can advise on the logistics and the best nozzle design and spraying systems currently available.

  • Start fitting out our Airforce high altitude capable airliners with bladdertanks that the Airforce already has for Helicopter range extension, and mist spraying gear for Stratospheric SO2 enhancement. This creates high altitude cloud condensation and also reflects sunlight back into space.

    It is a natural process via volcanoes - e.g./ the Pinatubo eruption put enough SO2 into the global stratosphere to stall global warming for 2 years in 1980, and via Di-methyl-sulphide released by oceanic phytoplankton.

    The loss of over half the oceanic phytoplankton in the southern ocean over the last 100yrs is definately a factor in the runaway melt, and highest local warming on the planet that West Antarctica has been experiencing in recent decades.

    Also burning dirty coal and ship bunker fuel, that releases SO2 has been worldwide shielding us from half the effect of Anthropogenic Greenhouse Agents to date.

    While the Arctic needs a SO2 veil most urgently, we will need to do this worldwide as we drop dirty coal, and the Antarctic summer could really use some help too. So allocation of the Airforce jets to this for the next few decades anyway is very appropriate. 

The IPCC has seriously dropped the ball on climate change and no further attention should be paid to any of their predictions for the following reasons:
  • The Arctic sea-ice models used for the predictions they are still making and planning to present in the IPCC5 report due out 2014 but wikileaked a month ago, are based on linear extrapolations (same loss of area each year) of seaice AREA trends 1980-2001. Since 2001 even sea ice area has been in an exponential summer crash. Whats far more important than sea ice area is sea ice volume. Up till 2003 the only ice thickness measurements available were from nuclear submarines taking Arctic Scientists like Peter Wadhams on several trips a year to sonar scan the thickness of the icepack from below. Since 2003 there has been high resolution radar satellite imaging of the entire arctic ice-cap giving a full dataset.

  • The 1971-2003 sonar data was not a complete imaging of the whole icecap so modeling the total was required. This is being seized on by the the IPCC as a fantasy to protect their cherished belief that their old ice-area models are valid.

  • The IPCC5 report is going to say(if they don't wake up and change it), things like: "minimum summer sea-ice area is predicted to be down by 35% on 1980-2001 levels by 2035". That would require quite a large recovery of the arctic sea ice from where it is now, since its already some 50% down in minimum summer area from 1980-2001 levels.

  • IPCC models on warming global temperatures are still not including any of the many feedbacks (eg/ accelerating release in the arctic of methane, CO2, and NO2) that have been for some years now accelerating the rate of warming. Actual data in recent years has warming rates far above the curves of IPCC models.

  • IPCC reports are edited before release by "special interest groups" like big oil.

Please excuse the war metaphors used in the following. Its very valid to call for an international war effort as AMEG are, and this report is going out to multiple recipients, including web forums for mobilisation of public opinion to assist Government and enviro group action and trying to rev everyone up appropriately.


The Greatest War Ever!

Hopefully the greatest war there will ever need to be.

A call to arms, lessons from the history of mankind and all life on earth, and some much needed moral boosting.

The Arctic Methane Emergency Group www.AMEG.me are very right to name this War. This group, founded by the head of Arctic studies at Cambridge University Peter Wadhams, contains some of the most informed and reputable, scientists in the world climate science community. Their guts in speaking out loud and clear needs to be respected with our attention and actions.

Its the greatest war ever in every sense of the word great. Great as in huge, great as in fabulous. It must unite all peoples, creeds and indeed life on this planet behind the common cause of saving life on earth from now almost inevitable, and unimaginably huge suffering mayhem and death.

The only question is how soon we all acknowledge this war and how soon we all consider ourselves drafted to our clear duty in it. If this does not happen fast then this war will become unwinnable.

In this war our weapons are not guns and bombs, not nukes and tanks. We must fight it tooth and claw, but in this war our teeth are our knowledge and our claws are our technology.

Its a war that humankind and the planets bio-geosphere have already been fighting for several thousand years without us humans even realising it.

The Chinese say that every problem is a mix of danger and opportunity. Lets appreciate, both the danger and the opportunity.


A Reconnaissance of the Battlefield.

Even before the industrial revolution a battle in this war raged for 2000 years. On one side of this battle, the side against the survival of complex life on this planet was the invention of monocultural large scale agriculture and its associated deforestation. This weapon of mass destruction was massively deployed by the Roman Empire, then spread worldwide by western European culture. It resulted in the dumping of a slow burning 500 Gigaton C-bomb on the planetry oceans and atmosphere by the reduction of organic carbon content of the worlds soils from 2000 gigatons Carbon to 1500 gigatons Carbon.

(In the language of eco-climatology tons C or tons carbon means the total mass of the carbon atoms in the CO2, methane or other organic carbon molecules being described)

This C bomb, released slowly as it was, went down the Arctic plug-hole, and has been hiding in the deep oceans for a millennia.  Now studies in the southern ocean showing CO2 being net released not absorbed have revealed its coming back up.

Until the 16th century AD not all humans were on the side of evil in this battle. Its now known that the peoples of Amazonia were fighting for the planet. The first European explorers at that time to sail up the Amazon reported that the banks of the great river and its tributaries were lined with urban communities of up to 50 thousand people. These great geo-engineers transformed the Amazon basin with great canal systems connecting the river valleys 2000 km from Venezuela to Paraguay. They dug artificial rectangular basins up to 20 km long for floating hydroponic gardens of corn, potatoes and tomatoes.

Their greatest geo-engineering feat though was to transform 10 percent of the land area of the Amazon basin from rain leached infertile soil to Terra Preta (spanish for "black earth") by layering biochar in the ground from pyrolysis of their domestic wastes and other biomass. This miracle soil maintains fertillity for thousands of years, sequesters moisture, beneficial bacteria and fresh organic carbon from jungle humus far better than any other soil on the planet. The carbon they were sequestering was offsetting that being released from soils across the Atlantic.

Their heritage from conserving and nurturing their ecologies is, though threatened and diminished by us now, the richest and most diverse ecosystem on the planet.

Then in the unintended by mortals, yet biggest act of bio-warfare ever, the diseases introduced by those 16th century European explorers demolished that civilisation and many others throughout the Americas, and in a century their sustainable wood based infrastructure rotted away almost without trace.

NOW we get to honour their memory and their legacy of permacultural wizardry by transforming the stripped soils of the world to Terra Preta as they did.

We must at this point have no doubt whatsoever about the seriousness of the consequences in the contract with our Earth that we have stupidly signed all life on the planet up for.

It seems we have initiated the Earths emergency carbon burial response. This means a rapid transition to what is called in paleoclimatology a super-greenhouse earth and an anoxic ocean event. http://en.wikipedia.org/wiki/Anoxic_event
  • This means ocean temperatures rising to over 40C in the tropics and over 27C at the poles.

  • Super-cyclones so powerful we cannot even imagine rage all year round from the equator to the poles.

  • The deep Oceans lose all oxygen and become stagnant and dominated by anerobic bacteria, producing hydrogen sulphide that poisons animal and plant life on the land and in the oceans.

  • The surfaces of the oceans become colonised by photosynthesising green and purple sulphur chemistry bacteria that slowly over a period of hundreds of thousands to millions of years bury the overburden of carbon dioxide as ocean floor sediments.

These emergency buried sediments are the origin of all the worlds oil and gas shale layers.

We have been grossly disrespecting the suffering and sacrifice of complex life that happened in these periods by digging that carbon back up and putting it back in the oceans and atmosphere.

The best known and most serious so far of these super-greenhouse events is the end-permian mass extinction of 252 million years ago. This event resulted in the extinction of 96% of marine species and 75% of land ones. It was the only known mass extinction of insects and ocean acidification wiped out all corals (todays corals took many tens of millions of years to evolve from sea-anemonies after that) and nearly all creatures with skeletons and shells from the oceans.

The "tipping point" that initiated the end permian and some twenty other more minor super-greenhouse/anoxic ocean events, that have been well studied is thought to be CO2 levels reaching around 1000ppm. This may sound like a lot compared to current levels approaching 400ppm but its not. There are two reasons for this:
  1. Firstly, the CO2 thermal absorption frequency band (the range of thermal electromagnetic frequencies that are absorbed by CO2) is already nearly saturated, and an extra 600ppm has a smaller extra effect than it appears to uninformed scrutiny.
  2. Secondly, the extra effect of far more powerful greenhouse agents such as methane, nitrous oxide, black carbon smog, tropospheric ozone, halocarbons (each with their own seperate thermal absorption bands) that we have put in the atmosphere, likely has us past that 1000ppm CO2 equivalent threshold already.
Furthermore, the Arctic Sea ice volume is in a very clear exponential collapse, as is clearly illustrated by the PIOMASS study. Strongly predicted to be completely gone in September within the next three years and completely gone for six months of the summer/autumn by 2020.

-This will, through sunlight being absorbed by the arctic ocean rather than reflected back into space by sea-ice, double the warming effect currently being experienced from greenhouse agents alone.

- On top of this the latent heat of thawing being absorbed by polar ice melt has been offsetting by 25% the worldwide warming effect of greenhouse agents and when its gone this additional effect will accelerate arctic warming.

- The warm gulf stream will also colonise the entire Arctic ocean further accelerating Arctic warming.

The Arctic defrosting cannot be allowed to happen.

Arctic land and shallow submarine permafrosts are storing about 5000 billion tons C of organic carbon, mostly as methane. Compared to the 234 billion tons C of CO2 added by us over the last 200 years, and less than 5 billion tons C of methane currently in the atmosphere, this is a colossal amount.

About 2.5 billion tons C of methane per year was estimated as being released from the East Siberian Arctic Shelf (ESAS) alone by Shakova's study from 2005-2008, caused by warming to date. It has increased since then there and throughout the Arctic.

The imminent defrosting of the arctic will cause rapidly accelerating release of a large part of the 5000 billion ton C total and the rapid warming of the entire planet by a global average of 5 to 10 degrees celsius within a few decades.
The chart below shows the current situation, and the situation should another 4.5 GtonC methane be released over the present 4.5 GtonC methane in the atmosphere, totalling the effects of greenhouse and aerosol agents.

As can be seen the earth is likely in Super-Greenhouse Anoxic Ocean mode already.

There are reasons why this situation could be more serious than the end permian mass extinction:
  • The geography of the time had all the earths continents pressed together into the supercontinent Pangaea, with only one small icecap perched on the end of it. This means it is implausible that there could have been as much organic carbon stored in polar permafrost as today.

  • There were shallow inland seas that were not as vunerable to anoxia as the world ocean and may have allowed some marine life refuges.

  • The vast interior of Pangaea would have allowed land animals and plants some refuge from the fierce cyclones and colossal rainfalls near the coast. Today the dispersed and more coastally exposed landmasses would not allow this.

  • The injection of CO2 from the Siberian traps flood basalt eruption and the initial warming of about 5C happened over up to 5000 years allowing some geographic migration of land animals and plants to cooler latitudes. Today the damaged ecologies we have and the far more rapid onset of the event would make this far less possible.

  • Onset of the anoxic ocean event in the end permian probably happened after the initial 5000 year period and was most probably caused by methane from dissociating deep ocean methane hydrates as the deep ocean warmed. This also causing an additional 5C global warming. Methane hydrate deposits in the deep ocean today are most likely more extensive, estimates ranging from 5 000-78 000 billion tons C, and the secondary carbon pulse from them could start 300-1000 years from now. Today we have a serious prospect of a double anoxic initiation, the first from shallow and land organic carbon stores and the second from the deep ocean hydrates.

  • The Sun is some 20% hotter than it was then.

  • The transition from a world where substantial ice-caps reflect a lot of sunlight back into space to one without them will likely result in a more extreme temperature jump than at the end of the Permian age.

There is a serious risk that if we let it happen, the coming event will remove all multicelled life from planet Earth.


What must be done.

Its now brutally clear that no safe atmospheric CO2 ppm above the 280ppm maximums of the last few million years exists for Earth today. It's way too late for us to simply wind down our fossil fuel use or even to abrubtly cease it. We have to with the most immediate urgency deploy all the measures AMEG are suggesting and any more that we can think up to delay the Arctic crisis. We can be sure that until CO2 is back to near 280ppm and other powerful greenhouse agents are vastly reduced, delaying the Arctic C-bomb is all that we are doing.

Until we are back to a 280ppm of CO2 and global warming potential equivalent of other agents, not only must we drop all fossil fuels like the red hot coal that they are, it must be all hands to the carbon pumps.

For one thing this means bio-charing and reforesting with diverse ecologies across the globe. The grazing animals don't all have to go, they will be far happier grazing clearings and under trees with summer shade and not wading in bogs all winter.

The most promising carbon pump down scheme is Ocean fertilisation. To some extent this can be viewed as Ocean ecosystem restoration. Its now known that the photosynthesising, base of the foodchain productivity of the Oceans has dropped about 40% in the last century. Due to this and our brutalising of the biodiversity and total mass of fish stocks the Oceans ecosystems badly need to be nursed back to health.

Since we've let things get so far without acting, we now have the necessity and in fact opportunity and privilege of creating fertile new ecology in the around 80% of the deep Ocean areas that are called "desolate zones" because there is currently almost no life in them whatsoever. In some parts of these desolate zones the only thing that is stopping productivity is trace amounts of iron, but now we must fertilise also the larger desolate areas with other nutrients also.

Our teeth and claws for doing all this are fortunately well developed at this point and becoming more developed every day. Some of the carbon pumped down by ocean fertilisation will go to the deep ocean and sea-floor.

Some of it we need to harvest, mostly as krill, for biofuel for our existing cars and carbon-negative powerplant conversions with the byproduct of this being bio-char for our soil replenishment/land carbon sequestration. And as food to replace displaced agriculture.


The long game.

When we are back to a (relatively) safe 280ppm CO2 and have also dealt with other greenhouse agents we will have time to draw breath and make an important decision. Whether to stop there or keep going, coaxing the planet back into another Glacial age over the next 1 or a few thousand years. The pattern of the last million years or so has been revealed, of glacial ages about 80-90 thousand years alternating with interglacials like the last 10 thousand years, usually lasting 10-20 thousand years. It was once thought that the earth was about ready to return naturally to another glacial period. Its now believed that orbital forcing -cycles of the earths axis tilting relative to the sun, maximum/minimum distance from the sun in annual orbit etc will be weak for the next 50000 years, making it unlikely that the earth will return to the happier and much safer times of a glacial period naturally for that long.

Its a widespread but false belief that "Ice ages" or glacial periods as is the correct term, are a tough time for humans on earth. Its true that northern areas of Europe and North America, the south of South America, and New Zealand are covered by Ice sheets and dry and windswept tundras. But even now most humans live in more equatorial regions, now uncomfortably hot, wet and stormy near the equator, and vast subtropical deserts like in the Sahara, middle east, Chille/Bolivia and Australia. In interglacials these are comfortable temperate areas with mild consistant rainfall and rich life on the land. Vast fertile continental shelves rise out of the sea, in the Caribean, connecting from Asia to Tasmania, between the middle east and India, extending massively the subcontinental plateaus of the nth island of New Zealand of New Caledonia and Easter Island . The coral atolls of the Pacific, Carribean, and Indian ocean become huge fertile plains with narrow entrances to deep inland harbours through 300ft high coral barrier walls that surround them. The Oceans have far higher and more widely distributed productivity than today, fertillised by 50x more windblown dust than now, glacial loess from the tundras circling the globe in subglacial lattitudes. Theres much evidence come to light in recent decades that the last glacial epoch was a time of great human civilisations that spanned the whole globe. Megalithic roads and ruins have been discovered under the sea in the Mediterranian, near India, between Yonaguni and Okinawa, inside Australias great barrier reef, throughout the pacific islands and in the Carribean. A ring of Moai circles Easter island beneath the waves. Mitochondrial DNA groups that track the female lineage show the fingerprint of a civilisation spanning equatorial lattitudes from the east coast of India, through southeast Asia, right across the Pacific as far south as New Zealand and on the west coast of nth, central, and sth America. Conversely the male y-chromosome DNA groups show almost only the traces of central Asian invaders conquering those areas in several waves over the last 12 thousand years or so. The global distributions of Coconuts and Bananas, both of which don't survive more than a few days in the sea, and their distant relationship from natural ancestral forms suggests humans were global traders in ancient glacial times.

We would be well advised to keep pumping down CO2 to the 90-180ppm of a glacial epoch and bunker the Arctic C-bomb in a deep freeze.

Provided we can maintain our technology till thats done, we might consider the east Siberian Arctic shelf as possibly the most dangerous geologic feature there has ever been for life on this planet, and suffer its existence no longer.

With the luxury of being able to see gradual injections of carbon into the bio-geosphere as something to expand biodiversity and biomass on the planet at that time, we might think its wise to blast the ESAS off bit by bit into the depths of the arctic basin over a period of centuries.

We cannot know if we might still have the knowledge and technology to recognise and deal with another Arctic crisis like the present one at some time in the near or distant future. Not disposing of the ESAS could threaten earths life again some day.

The longer game.

In my opinion there could be no higher calling for an intelligent species like ourselves than to spread the miracle of diverse life to other planets. This job for the future is one, assuming we're still around, we'll one day have to face.

The claws of our telescopes and spectrometers, some time ago taught us of the life cycles of suns. Ours is destined to slowly get hotter and one day within the next few billion years our Earth will suffer a stupendous runaway greenhouse effect. As once happened on Venus, how long ago we don't know, our oceans will boil. The greenhouse effect of that water vapour will feed back on itself until surface pressures are about 1000 times current from an atmosphere 1000km thick. The land beneath will glow a dull red, scorched by temperatures of 600C. There is suggestions that Venus may once have nurtured a biosphere. Our laser inteferometry has detected particles the size and shape of those green and purple sulphur chemistry photosynthesising bacteria that proliferated in super-greenhouse Earth Oceans, in the sulphuric acid cloud tops 1000km above Venus's surface. In those cloudtops temperature and pressure are simular to Earths surface today. Some suggest that these extremophile bacteria blew frozen on the solar wind to Earth, and got life started here.

Our next potential home is probably Mars. Mars needs lots of work to be a lasting stable paradise for a diverse bio-sphere, so we should probably get started fairly soon. Its good that we are learning whats needed for managing a planetry eco-geosphere now.

There's hints on Mars of how it can be done.

There appears to be no question that Mars had a thick atmosphere and lots of liquid water on its surface within a few tens of thousands of years ago. Also a working magnetic engine at its core as recently as 50 thousand years ago, providing a magnetic field to protect it from the radiation of cosmic rays and the solar wind. All that may have come about as the result of two giant comets striking squarely the north and south poles of Mars a few million years ago. They left the two biggest impact craters in the solar system, 2000 and 2500km across, likely adding water and melting Mar's core to kickstart its magnetic engine. The volcanism that was stimulated would have given mars its atmosphere.

Most likely mars is too small to keep an earthlike atmosphere and oceans for a useful period so we'll have to harvest the asteroid belt, and pepper its surface to build mass, with large asteroids of rock, iron/nickel, hydrogen/carbon/nitrogen/oxygen, and ice composition. The asteroid belt is a perfect resource for this. Something like this happened to Earth in the "late great bombardment" something like half a billion years after the collision of two planets that formed the Earth-Luna system, not long after the Suns nuclear furnace first sparked into life. The late great bombardment was responsible for most of the moons craters, and most of earths water. We'd be best to build a moon much like Earths for Mars too. From the asteroid belt. Or steal one from Jupiter. Lunar tides in oceans are great for stirring up life, and tides in planetry mantles knead them to help keep them molten and magnetic engines running.

Once Mars has settled down from that bashing, those purple and green, sulphur chemistry, photosynthesising extremophiles can be seeded there. To convert the CO2 and sulphuric acid atmosphere to breathable oxygen.

From there its all easy.

The longest game.

The Sun will continue growing bigger and hotter, destined eventually to swell its surface past the current orbits of Venus, Earth and Mars. Even mighty Jupiter will eventually fall in and be consumed by the red giant Sol. As that happens we'll have to migrate outwards, spreading life to the moons of Jupiter, Saturn, Uranus and Neptune. These giants all have many great moons for us to help life take root on some almost as big as earth. Some already look like earth did several times in lifes history here. Covered entirely with crusts of ice, salty oceans beneath heated by tidal forces and rocky cores containing radioactive potassium and uranium. Some think that life may already have got started there, as ecologies fueled by sulphur chemistry rather than photosynthesis. This type of life exists on earth in the deep ocean trench volcanic zones.

When the Sun has finished growing it will suffer a violent transformation. It will collapse rapidly to become a tiny red dwarf. This fierce little mother will be, like our nearest neighbor Proxima Centauri, an ancient solar system whose lifecycle has ended, whats known as a flare star. Her energy output will oscilate wildly and colossal flares and coronal mass ejections would scorch with radiation any planet we put near enough her to be warmed.

But we could help her give birth.

Orcas, Pluto, Haumea, Quaoar, Makemake, 2007 OR10, Eris, Sedna are known variously as ice dwarf planets, plutoids or trans-neptunian planetoids.

Balls of frozen water, methane and ammonia with rocky cores, diameters of up to 2350km, its currently estimated that thousands of these exist. It would be easy to nudge these bodies into trajectories that use a gravitational slingshot from neptune. This can easily shoot them out of the solar system at escape velocities that would get them to nearby stars with potential for life to be spawned. We could be doing this as early as when we first start renovating Mars. Artificial intelligence systems could fertilise virgin planets so that they are ready for complex ecologies long before the Sol system dies. Sedna is already near escape velocity, only visiting near Neptune every 10,000 years, she spends most of her time in the Oort cloud which extends nearly a lightyear from earth, a quarter of the way to the 3 star Centauri system.

The outer Oort cloud is believed to contain several trillion individual objects larger than 1 km and many billions with diameters above 20 km. The inner Oort cloud is modelled as having 10-100 times as many as the outer.

Plenty of cosmic eggs for the spawning.

In the end the proponents of fecund universe theory might be right.

Maybe once its got started, life becomes more and more complex, gathering knowledge and technology until before the universe its housed in winds down and dies, life has aquired the means of spawning new universes. With laws of physics tuned for even more interesting life to develop. Maybe its already happened. I hope one day we'll be around to know.
