Record Temps everywhere and now due to mass methane releases, the 130X more toxic than C02 greenhouse methane gases has pushed up to 400 ppm. A threshold that assures a continual feedback loop of melting Arctic and ever increasing greenhouse gas at the North Pole. It generally takes 1 1/2 – 2 years before deadly C02 from methane releases in the tundra is in full effect. God help us all and may we learn from our massive mistakes that are causing this world-wide 6th Extinction event, if any of us make it through the next decade or two….meanwhile, the sheeple sleep for just a tiny, tiny bit longer before it all becomes too hot everywhere for all to deny we are going extinct, very fast, very soon, truth be told, not sold.
The Arctic is now going to be ice free, the first time in 3.6 million years. Is this important and critical knowledge? Read below as to the predictions, just two years ago, that this event would not happen for another 50 years! There is no more important subject matter than this

While warming may appear to be only mild in some areas, it is felt even fiercely in the Arctic. Most heat (well over 90%) goes into the oceans, which hits the Arctic particularly hard as the Gulf Stream pushes a lot of warmer water into the Arctic Ocean. Warming in the Arctic is further accelerating due to additional circumstances and feedbacks that are specific to the Arctic, such as albedo feedbacks (as further discussed below). Continued warming in the Arctic threatens to trigger methane releases large enough to terminate civilization as we know it and to cause widespread and massive death and extinction.
Feedbacks are described in more detail in posts such as Diagram of Doom (image below) and Changes to Polar Vortex affect mile-deep ocean circulation patterns.

One such feedback is albedo change — retreat of Arctic sea ice results in less sunlight being reflected back into space, as further discussed in Albedo Change in the Arctic. Loss of Arctic sea ice is effectively doubling mankind’s contribution to global warming. Increased absorption of the sun’s rays is the equivalent of about 20 years of additional CO2 being added by man, Professor Peter Wadhams said in a BBC article.
Methane is kept stable inside hydrates as long as the temperature remains low. Since methane expand some 160 times in volume, compared to its compressed frozen state inside the hydrate, warming of even a small part of a hydrate can cause destabilization across the entire hydrate. It may take only a small rise in temperature of a single conduit in the sediment to set off a large abrupt release of methane, which subsequently threatens to cause further releases elsewhere in the Arctic Ocean and trigger runaway global warming, as described at the methane hydrates blog.
As image 9. (left) shows, based on the figures by Shindell et al. and using a horizon of 10 years, methane’s GWP is more than 130 times that of carbon dioxide.
In image 9., the blue line is based on IPCC AR4 figures. The red line is based on figures from the study by Shindell et al., which also concludes that methane’s GWP would likely be further increased when including ecosystem responses.
The danger is that a large abrupt methane release in the Arctic will trigger further local releases. This danger is particularly high the first few years after the methane enters the atmosphere, due to methane’s high initial warming potential, as further discussed in the next two chapters.
By contrast, much of the methane from an abrupt release in the Arctic Ocean will initially remain concentrated over the Arctic Ocean, which covers only 2.8% of the Earth’s surface. While the methane will eventually spread around the world, this will take time. The Jet Stream acts as a barrier, preventing air from flowing out of the Arctic and preventing air from elsewhere to enter the Arctic. Nesbit mentions that a major methane release in the high Arctic would take 15-40 years to spread to the South Pole.
Given the lack of hydroxyl in the Arctic atmosphere (see below), it may well be possible that some 20% of the methane from an abrupt release over the Arctic Ocean still remains there after 5 years. Using a GWP for methane of 130 times that of carbon dioxide over a period of ten years would already lift methane’s LWP (local warming potential) over the Arctic to (130*100:2.8:5=) 929 over 10 ten years. For a shorter period, the Arctic LWP will be even higher. In conclusion, local concentration alone makes that a methane cloud still hanging over the Arctic five years after its release will have a huge LWP, i.e. well over 1000 times the potency locally that the same mass of carbon dioxide has globally.
Additionally, high temperature anomalies make that methane releases at the poles will be felt more severely than elsewhere on Earth. These high temperature anomalies are the result of feedbacks such as albedo changes caused by melting. Image 11. below, from Skeptical Science, pictures the loss of ice mass on Antarctica.
Another study finds that drastic sea ice shrinkage causes increase in storm activities and deepening of the wind-wave-mixing layer down to depth ~50 m (164 ft) that enhance methane release from the water column to the atmosphere. Indeed, the danger is that heat will warm up sediments under the sea, containing methane in hydrates and as free gas, causing large amounts of this methane to escape rather abruptly into the atmosphere.
Above image 21. illustrates how this dangerous situation has developed in the Arctic, and what can be expected in future without action. The image pictures three kinds of warming (red lines) and their main causes:
Emissions by people cause global warming, with temperatures rising around the globe, including the Arctic. High levels of greenhouse gases in the Arctic, combined with the impact of aerosols such as soot, and rivers that end in shallow waters in the Arctic combine to cause high summer temperature peaks in the Arctic. In other words, global warming is amplified in the Arctic.
Accelerating Arctic warming is caused by at least ten feedback effects. Melting of snow and ice causes albedo changes, i.e. less sunlight gets reflected back into space and instead gets absorbed, causing further warming. Additionally, soot, dust and volatile organic compounds settle down on snow and ice, causing further albedo change.
Three of these feedbacks are pictured as gold lines:
Fires feedback: Accelerated warming in the Arctic is changing the Jet Stream, contributing to increased frequency and intensity of droughts and heatwaves.
Albedo feedback: Accelerated warming in the Arctic also speeds up the decline of ice and snow cover, further accelerating albedo change.
Methane feedback: Methane releases in the Arctic further add to the acceleration of warming in the Arctic, further contributing to weaken Arctic methane stores, in a vicious cycle that threatens to escalate into runaway global warming.
Runaway warming. Accelerating warming further weakens the capability of the seabed to hold the methane that is contained in the form of hydrates and free gas in sediments under the sea, in a vicious cycle that threatens to lead to runaway warming.
The heatwaves in Russia provide a gloomy preview of what could happen as temperatures rise at high latitudes. Firestorms in the peat-lands, tundras and forests in Siberia could release huge amounts of emissions, including soot, much of which could settle on the Himalayan plateau, darkening the ice and snow and resulting in more local heat absorption.
Not only will high temperatures be up to 20 degrees warmer than average, but lows will be 5 to 15 degrees above average across the region. Lows will only drop into the 80s for much of the Desert Southwest, while downtown Los Angeles will see temperatures only dip into the 70s, about 10 degrees warmer than average.

What a load of bollocks! Have you seen how much money the likes of Gore and his ilk have made out of global warming, oops sorry it’s climate change now apparently! The climate is always changing and the sheer arrogance that we created the problem and therefore can change it is breathtaking! Lets ask NASA for some satellite pictures of the ice caps, oh they can,t can they. If this is based on FE then it implies we know the limits of the ice barrier formally known as the south pole, do we??????? About 30 years ago now we in the UK, were being lectured on how we were heading toward the next ice age but come 1995 or thereabouts we were told we would be growing grapes in Scotland due to the dire consequences of global warming, now climate change. The fact that the Romans had vineyards in the UK 2000 years ago seems to be irrelevant apparently and then the fact that the river Thames froze in the sixteen and seventeen hundreds and that the sea still freezes as waves turn in some parts of the world must also be disregarded because it does not fit the MO of scaremongering to implement more carbon tax for the rich!
My problem with this, is all the talk of the ‘globe’ – We are on a flat Earth for goodness sake!
My other gripe is that If the BBC has anything to do with this article then say no more.
Exactly Vic the BBC has always pushed the AGW agenda but if the so called researchers change the science again to suit they will push that lie. It’s all about funding these twats and jobs for the boys etc.
Shouldn’t PROOF be reasonably possible now? Don’t they have ways to measure things?
Depth of ice, nelting, sizes of ice flows?
Why talk? Get measurements, compare? I think there would be computer programs to analyze data.
Whatever figures they come up with will only be designed to show proof of their agenda and you and I would still have no way of knowing if the figures are correct or not. Also what would the figures be based on, its all theory and theory is not and never has been proof. Computer programs only give answers based on the data entered therefore you can always get the outcome you want! ITS ALL LIES DELIVERED BY FULLY PAID UP LIARS TO MAINTAIN THEIR FUNDING! Step out of line and funding ends or in some whistle blowers case’s you life ends too!
It seems we have two major problems going on at the same time. “Climate change” which is nature’s normal solar cycles due to the north and south electromagnetic vortex pole shifting (not the same thing as a north and south geographic regions), and “climate warming” caused by manmade abuse of our natural environment.
I agree with comments above…These two real and serious facts are being manipulated by an easily flawed ” hierarchy of evidence, research and peer group acceptance.” Then these controlled results are published in a highly accredited scientific journal, publication or science bible. Next these outcomes are promoted or used by corporations and government for their money making strategies, to market ideas in competition, enforce government policies of control and finally to enforce tax revenues. On the surface it looks like checks and balances, but it seems, the loop holes are everything but.
To me “mainstream hierarchical science” a new age religion, has put itself upon the god pedestal by also using brainwashing dogma. Most likely bought and paid for by the same materialist elite group, to keep people confused. They accomplish agendas by using formulas based on philosophical theories to bedazzle and keep their subjects disoriented by a supposedly higher educated language to keep the 1% ruling the 99. And when these groups are called into question by the 99%, what happens? The 99 are ignorant, not as educated, hieratic, disobedient protesters, liars, terrorist, on and on the control to keep us subject to their authority.
The same tactics ancient government and religion used with esoteric and exoteric legalese double speak. BUT today all these groups and agendas are slowly being exposed by their own greed of contradiction as more and more people are waking up to the “industrial age” scams that was built upon abusing human nature that worked in the past.
According to many scientist ..(don’t take my word for it, if this is something that is of interest to you… please do your own research) The earth poles shifting polarity is believed to be a natural solar cycle that takes on average around 100 years to complete. When this cycle completes it is suppose to bring on a much colder period or even a mini ice age on the earth. Many “scientist” say we are expected to start cooling down due to the building up of ice in the geographic north and south pole regions.
For whatever reason, the electromagnetic poles are reported now to be moving faster than science originally thought to be the normal cycle. These scientist predict if the poles move to quickly the electromagnetic flares from the sun will become too intense creating a very real danger of significantly damaging power grids that could take months or years to repair among other consequential havoc.
On the other hand, other scientist say our earth is warming at a alarming rate due to manmade toxicity that has seriously damaged our Ozone layer and the ph balance of the oceans and fresh water which also has dire consequences.
So question is: What is the 99% suppose to believe is fact? My biggest concern is: how much science experimentation via geoengineering has already been done against us and our ecosystem that will take years to overcome if it can, and is secret technology being used to manipulate the polarity of the earth in a effort to bring on a cooling trend …
Very well put. I think you just have to follow the money and we will have some of the answers.
