The Worst News Ever 2
#22435436 - 10/26/15 10:39 AM (8 years, 3 months ago) |

Hi Guys.
I am sad and frightened to learn that we apparently are facing a global worst case scenario as we speak.
If you want to learn what I am talking about, google "Methane Permafrost" or "arctic methane" or "seabed methane" and read what comes up.
Basically unfathomably large deposits of methane on the ocean seabed, under the earth and under the permafrost is being released into the atmosphere at this moment and worsening rapidly, creating a self reinforcing feedback loop.
Essentially, this appears to be the end of the world as we know it.
I hope and pray that the enormous amount of scientific information on this is somehow wrong or not as bad as it looks, and I would welcome any explanation of why we should NOT worry about this.
I am praying this will take 100 years to totally destroy our civilization or our planet.
If anyone can explain this in simple terms, debunk it, or provide some hope, or provide any helpful info on this, I would appreciate it.
Enjoy your lives, hug your loved ones, and maybe consider not having kids, if you don't already have them.

Thawing permafrost could have catastrophic consequences, scientists warn
Scientists at the UN climate negotiations in Bonn warn that new data about the melting of the Earth’s permafrost, and projections of a “permafrost carbon feedback loop,” suggest that the Earth is reaching thresholds where only a new ice age could reverse the impacts of global warming.
Sue Natali, of the Woods Hole Research Center in Massachusetts and co-author of a paper recently published in Nature, told negotiators about the new data and says the numbers indicate we are at risk of slipping into runaway global warming.
“What’s important about these numbers is that, in theory, we can control deforestation and land use change [and] we can control our fossil fuel emissions — but once permafrost starts to thaw, we cannot control how much carbon dioxide and methane is released by microbes into the atmosphere from thawing permafrost,” Natali says.
Permafrost is ground that remains frozen for two or more consecutive years. In some areas, permafrost has been frozen for as long as 40,000 years. Permafrost regions cover about 25 percent of the northern hemisphere's land area.
Carbon in permafrost is frozen in the form of various types of organic matter. But when permafrost thaws, microbes decompose that organic matter. And just as humans breathe out carbon dioxide, so do microbes. And they also release methane, which is a much more potent greenhouse gas than carbon dioxide.
Current projections indicate a 30 to 70 percent decline in near-surface permafrost by the end of this century, Natali says. That wide range is a result of different emission scenarios. “Under low emission models, we can expect about a 30 percent decline in permafrost. But under our current emissions scenario, up to 70 percent,” she explains.
If 70 percent of the permafrost thaws, scientists expect to lose 130 to 160 billion tons of carbon into the atmosphere by the end of this century. To put that in perspective, in 2013 the United States emitted 1.4 billion tons of carbon from fossil fuel combustion and cement production.
The feedback loop scientists describe works like this: Thawing permafrost will release large amounts of carbon dioxide and methane, which will lead to rising global temperatures, which will lead to further permafrost thawing, which will lead to rising global temperatures. And that trend is projected to continue through the rest of the century.
Scientists believe this feedback is already happening in the Arctic, where air temperatures are warming twice as fast as the rest of the planet.
Natali point out that the most recent IPCC report, which was already looking grim, did not include data on permafrost carbon emissions. Once this data is factored in, she says, scenarios for the future may look quite a bit more dire.
“International negotiators had set 2 degrees Celsius (3.6 degrees Fahrenheit) as an upper acceptable level of climate change,” she explains. “To remain below this target, our total emissions are limited to 790 billion tons of carbon. We've already released about 500 billion tons, so that leaves us a little under 300 billion tons. We can expect 150 of that to be taken up as a result of permafrost thaw.”
“This makes it very challenging for us to stay below the two degrees Celsius,” she continues. “Even under our lowest emissions scenario, we're pretty close to 2.2 degrees Celsius.”
This puts even greater urgency on reducing our fossil fuel emissions now in order to avoid a future driven by an irreversible carbon feedback loop, Natali warns.
“Not all of the carbon in permafrost will be released,” she says. “Our current expectation is about 10 to 15 percent of that carbon will be released into the atmosphere. That said, if all of the carbon of permafrost was released, this is not going to be a habitable planet for humans.”
This article is based on an interview that aired on PRI's Living on Earth with Steve Curwood
Permafrost Methane Time Bomb
For the most immediate threat in 2014 from a gigantic burp of methane please read this report and please start writing to and influencing your politicians.
A vast expanse of permafrost in Siberia and Alaska has started to thaw for the first time since it formed 11,000 years ago, marked in dark blue on the map. It is caused by the recent 3+°C rise in local temperature over the past 40 years - more than four times the global average. Peat bogs cover an area of a million square miles (or almost a quarter of the earth's land surface) to a depth of 25 meters. Those in Siberia are the world's largest.
What was until recently a barren expanse of frozen peat is turning into a broken landscape of mud and lakes, some more than a kilometre across. All only in the past 3 or 4 years.
Tipping PointsThis has the potential to release vast quantities of methane trapped by ice below the surface - billions of tonnes of methane. World-wide, peat bogs store at least two trillion tons of CO2. This is equivalent to a century of emissions from fossil fuels.
This is one of the most feared tipping points. There is a delicate threshold where a slight rise in the Earth's temperature can cause a dramatic change in the environment by triggering a huge and instantaneous increase in global temperature. See Footprints #3.
This melting is an irreversible ecological landslide - a vicious circular feedback that is becoming stronger and stronger, and is doing so more quickly with every passing summer.
Once started extreme global warming would be irreversible.
A significant part of the heat gained during the summer is held within the peat by the autumn snow that acts like a blanket to keep it warm, and thus the heat gained is incremental. This is why the present passion for carbon trading will make no difference to the outcome.
When we start heating these natural systems, the process quickly becomes unstoppable. We do not have any technological brakes we can apply. This is enormously important because we can't put the permafrost back once it's gone. The gasses stored there have the potential to raise temperatures even more than all of our past emissions. Permafrost Time Bomb
Since the bogs were formed they have been generating methane, most of which has been trapped within the permafrost itself, in ice-like clathrates.
It is estimated that the west Siberian bog alone contains some 70 billion tonnes of methane, a quarter of all the methane stored on the land surface of the world. This is equivalent to emitting 1.7 trillion tons of CO2, which is more greenhouse gas than has been emitted by humans in the past 200 years.
There are already impacts on roads and buildings which are collapsing as the ice-held foundations melt. In addition, once the bog dries out deep sub-surface fires ignited by lightning will themselves create more CO2 to add into the air.
Alarmingly, it has just been reported by Wetlands International that huge areas of wet peatland forests are being drained and logged in Indonesia and Malaysia. Along with the ensuing peat fires this contributes 2 billion tons of CO2, making South-East Asia the third largest polluter in the world behind the US and China.
North Siberian Arctic Permafrost Methane Eruption Vents Mantle Methane Leakage via Late Permian Deep Penetrating Fault and Shear Fracture Systems Rejuvenated by Carbon Dioxide and Methane Induced Global Warming
Abstract
In North Siberia some 30 permafrost methane eruption vents occur along the trend of the inner (continental side) third of the Late Permian Taimyr Volcanic Arc where the crust and mantle were the weakest and the most fractured. Deep penetrating faults and shear systems allowed molten basaltic magmas charged with large volumes of carbon dioxide and methane free access to the surface where they formed giant pyroclastic eruptions. The large volume of carbon dioxide and methane added to the atmosphere by this Late Permian volcanic activity led to a massive atmospheric temperature pulse that caused a major worldwide extinction event (Wignall, 2009). These deep penetrating fractures form a major migration conduit system for the presently erupting methane vents in the North Siberian permafrost and the submarine Enrico PV Anomaly. During periods of lower atmospheric carbon dioxide and lower temperatures, the permafrost methane vents became sealed by the formation of methane hydrate (clathrate) plugs forming pingos. The surface methane clathrate plugs are now being destabilized by human pollution induced global warming and the mantle methane released into the atmosphere at the permafrost methane explosion vents. This has opened a giant, long standing (Permian to Recent) geopressured, mantle methane pressure-release safety valve. There is now no fast way to reseal this system because it will require extremely quick cooling of the atmosphere and the Arctic Ocean. The situation calls for comprehensive and effective action, including breaking down the methane in the water before it gets into the atmosphere using methane devouring symbiotic bacteria (Glass et al. 2013) and simultaneously breaking down the existing atmospheric methane using radio-laser systems which can also form methane consuming hydroxyl molecules (Alamo and Lucy Projects, Light and Carana, 2012, 2013).
Late Permian Extinction Event
In the Late Permian a massive eruption phase occured along the entire central and north eastern part of the "Taimyr Volcanic Arc" producing an extremely wide and thick sheet-like succession of flood trap lavas and tuffs (Siberian Traps Large Igneous Province) that spread south eastwards over the Siberian Craton (Figure 2, Light 2014). During the Late Permian there was a major global extinction event which resulted in a large loss of species caused by catastrophic methane eruptions from destabilization of subsea methane hydrates in the Paleo-Arctic (Figures 2, 3 and 4)(Wignall 2009, Light 2014, Scribbler 2015, Merali 2004, Goho 2004, Scott et al, PNAS, Dawson 1967, Kennedy and Kennedy, 1976). Extreme global warming was caused when vast volumes of carbon dioxide were released into the atmosphere from the widespread eruption of volcanics in northern Siberia (Figure 2; Wignall 2009) whose main source zone, the "Taimyr Volcanic Arc" on land in northern Siberia (Figure 3) is not a great distance from the present trend of the Arctic Ocean Gakkel Ridge and the Enrico Pv Anomaly extreme methane emission zone. Because the Arctic forms a graveyard for subducted plates, the mantle there is highly fractured and it is also a primary source zone for mantle methane formed from the reduction of oceanic carbonates by water in the presence of iron (II) oxides buried to depths of 100 km to 300 km in the Asthenosphere and at temperatures above 1200°C (Figure 4)(Gaina et al. 2013; Goho 2004; Merali 2004; Light 2014).
Conclusions
Our present extreme fossil fuel driven, carbon dioxide global warming is predicted to produce exactly the same mantle methane release from the permafrost methane eruption vents along the Late Permian "TaimyrVolcanic Arc", subsea Arctic methane hydrates and the Enrico Pv Anomaly "Extreme Methane Emission Zone" by the 2050's, leading to total deglaciation and the extinction of all life on Earth.
Mankind has, in his infinite stupidity, with his extreme hydrocarbon addiction and fossil fuel induced global warming, opened a giant, long standing (Permian to Recent), geopressured, mantle methane pressure-release safety valve for methane gas generated between 100 km and 300 km depth and at temperatures of above 1200°C in the asthenosphere (Figures 1 to 6). This is now a region of massive methane emissions (Carana, 2011-2015).
There seems to be no fast and easy way to reseal this system. To sufficiently cool the Atmosphere and Arctic Ocean cannot be achieved in the short time frame we have left to complete the job. In some cases, it may be possible to reseal conduits with concrete or other material, or to capture methane for storage in hydrates at safer locations, but the sheer number of vulnerable locations and the size of the work involved is daunting.

Seabed methane leaks cause alarm
METHANE is leaking from the Arctic Ocean seabed at a much faster rate than previously believed, raising fears it could quicken the pace of global warming, according to a study published in the journal Science.
Scientists from Russia, the US and Sweden found that about 8 million tonnes of the potent greenhouse gas leaks from the shallow seabed of the East Siberian Arctic Shelf each year.
The research shatters the belief that sub-sea permafrost is an impermeable cap that prevents the release of methane.
The finding is significant because of methane's greenhouse qualities. It is more than 20 times as potent a greenhouse gas as carbon dioxide. Advertisement
Led by researchers from the University of Alaska-Fairbanks, the groundbreaking six-year study found more than 80 per cent of the deep water and more than half of the surface water had methane levels about eight times higher than normal seawater.
The scientists said the leak did not alter global warming projections ''alarmingly'', but warned it could be a precursor to much larger ocean emissions if the permafrost covering two million square kilometres of seabed destabilised.
''This discovery reveals a large but overlooked source of methane gas escaping from permafrost underwater rather than on land,'' the paper said.
''Ocean-bottom permafrost contains vast amounts of carbon, and experts are concerned that its release as methane gas would lead to warmer atmospheric temperatures, this creating a positive-feedback loop that would lead to more methane escaping from the permafrost and more global warming.''

ARCTIC DEATH SPIRAL AND THE METHANE TIME BOMB
The Arctic Methane EMERGENCY
John Nissen, chair of the Arctic Emergency Methane Group (AMEG), talks about the catastrophic dangers that the warming of the Arctic region poses to modern civilization and the possible extinction of humans due to abrupt climate change. This press briefing took place during the 20th annual Conference of the Parties (COP 20) held on Dec. 5, 2014 for the United Nation's Framework Convention on Climate Change (UNFCCC) held in Lima, Peru. 1ST PRESS BRIEFING: COP20: Global Arctic Methane Emergency #1 (12-4-2014 in Lima Peru)
Published on Mar 22, 2015
Global warming is causing CO2 levels to hit 400 ppm, a level humans have never seen. Droughts are spreading and Miami is reporting that the ocean is backing up in the drains.
With all of the global warming a new threat has emerged, the release of methane gas, trapped in methane hydrates on ocean floors. It's release is often referred to as the 'methane bomb'.
The last time a 'methane bomb' went off on earth, 80% of life on earth vanished (about 250 million years ago).

Scientists have known about this feedback loop for long time. Essentially, if CO2 warms us to a certain point where the methane releases become large enough that methane becomes the more influential greenhouse gas and the warming causes more and more methane to be released. This causes runaway heating.
Honestly, I think this is inevitable. Global temps this year are record shattering by a huge margin. Solar minimum is over and things are really accelerating this new solar cycle.

Livestock is a current major producer of methane, but the amounts stored in permafrost and hydrates is ten of thousand ands of times larger than livestock could ever produce.

On a serious note; I think you are forgetting moon. Those who have power to reverse this and start making attempts to solving these types of problems are the filthy rich. They have money. And until this shit reaches a tipping point where every man starts to see it effect us in a direct and undeniable way, people aren't gonna take it seriously. First it will be the third world countries that suffer, then it will be the first class citizens. Then eventually they will realize it and it will either b too late, or just in time. And then the process of changes will begin. I think scientists can concoct something

I sure fucking hope so. Personally I am executing a full blown end of the world plan right now, which is a combination of preparing for an unimaginable disaster and emotionally and psychologically preparing for my own death and to release attachment to this magnificent earthly creation.
asante I too hold to that beautiful hope.

For me this will be half stocking up on food and water and half meditating, cuddling my wife, doing yoga, praying and calling my loved ones. And maybe some DMT if I can muster enough inner peace.
