Here is the first of six videos. ‘Will Methane Clathrate Gun Only Fire Blanks?’ // Published on Feb 10, 2017.

Will a huge burst of methane gas be released from hydrates/clathrates in the Arctic as abrupt climate change takes out the sea-ice and snow cover?

That question is examined in great detail in a new paper by the United States Geological Society (USGS), ‘Gas Hydrate Breakdown Unlikely to Cause Massive Greenhouse Gas Release‘.

I discuss the key points from this paper, and assess what these findings mean to overall abrupt climate system changes.
———- ———-

Guy McPherson keeps moving his expected Near-Term Human Extinction (NTHE) date closer and closer. His latest claim is 9 years from now; namely by 2026.

I disagree with this premise. There is no scientific validity to these claims. No chain of logic leading to this conclusion. They are one persons “opinion”. To call them “fact” is absurd. They are opinion. We need to talk “probabilities”; not absolutes.

I asked online in jest if he has “fallen off his rocker”? He called me a “jerk”. I have been called much worse. He seems to be absolutely intolerant to any ideas that oppose his own. He puts himself on a pedestal, beyond tolerance of any criticism. That is not science, it is something opposite to science.

In a few months he will be saying that 7.5 billion humans will be dead by next year. Or perhaps even by last year?!

    You’re stuck in your Uni model chart world, Paul! It’s not the real world, GM is far more accurate than your Uni BS. What’s happening is far beyond your academic blurbs!

    This is a statement that I have been working on that represents my understanding of the recent prediction by Guy McPherson about the timeline for Human Extinction. It includes a quote from Guy in response to a question about it from Jennifer Hynes. I have revised it to include an emphasis on reduction in Global Dimming as well as on Methane. I have shown it to Guy and he gave me the go ahead to post it:

    Dr. Guy McPherson, Professor Emeritus of Natural Resources and Ecology and Evolutionary Biology at the University of Arizona, is an expert on Human Extinction, and therefore knowledgeable about the habitat necessary for human survival. As the global average temperature rises above a certain point, it’s not that human beings can’t live at higher temperatures, but that the plants that we and other animals depend upon for food cannot adapt fast enough and they die out.

    Dr. McPherson is now predicting that human extinction will occur within 18-42 months from now, based on the probability of giant methane “burps” due to the warming of the Arctic Ocean and Permafrost. Methane is a greenhouse gas that when forst emitted, is 100x more powerful than CO2 in trapping reflected sunlight, and this will result in a rapid temperature rise of over 1 C within a few days or months. This will result in a collapse of civilization because grains will not grow.

    The collapse of civilization, in turn, will result not only in a reduction in emissions of CO2 and other greenhouse gases, but also a reduction in the particulates that are also emitted in the burning of fossil fuels and reflect incoming solar energy back into space, the so -called “global dimming” effect, and the reduction in global dimming will cause the global temperature to rise even faster.

    As Dr. McPherson puts it, “Ice-free Arctic almost certainly triggers the 50-Gt burst of methane predicted by Shakhova et al. [2008]. The attendant 1.3 C rise in temperature causes civilization to collapse because grains can’t be grown at scale. Lack of global dimming adds another ~3 C. Earth is ~6 C above the 1750 baseline by spring 2018. About 2/3 of the temperature rise comes within a few months. I doubt there’s habitat for humans or many other animals at that point.”

    The 18-42 month range in the timeline reflects the uncertainty as to just when the Arctic Ocean becomes ice-free, based on the prediction of the US Naval Postgraduate School in 2013 that it would occur in 2016 +/- 3 years.

    For the research Dr. McPherson is using as the basis for his prediction regarding emissions of methane from the Arctic Ocean and Permafrost see the first Self-Reinforcing Feedback Loop here: The document also contains 68 other self-reinforcing feedback loops, all of which have a multiplicative effect in that they also reinforce one another.

    GM tends to expound other peoples work, then extrapolate between those works, rather than letting the people who put together the data do so. I think he started with a conviction that he was doing the right thing but when questions regarding his conviction arise I guess personal motives comes to play and he gets defensive as most other humans react (including myself).

    I have not heard the scientists draw conclusions outside their own papers. Meaning using the new knowledge to extrapolate a future using older papers as some kind of basis for a model of how the future will look like. Maybe the reason to that is that it is just too hard and chances are that one will simply jump to the wrong conclusions. Once someone announces sensational claims which are found to be wrong it will kind of get hard to get rid of the attributed ridicule. So they keep a conservative approach to avoid getting defamed.

    I think that a lot of people today are aware of the climate issue but they tend to jump to whatever conclusion which will keep their lifestyle unchanged unless the consequences will hit them up front.
    I still think that the only right thing to do for you is to keep up the science and only predict things that are reasonable within the limits of known and verifiable data. When the truth is told to people and they can confirm it the ones who deliver the information will perhaps get increased attention.
    But I won’t bet that people will change at all even if they know the truth… That’s another matter.

    I asked Guy Mcpherson on “Nature Bats Last” on FB, about the USGS. He said that
    those in field have more credibility than just the pure academics, who
    model without using new facts to upgrade their models. Thus the Russian
    team, and Wadhams, I’m guessing, would have more credibility than the
    USGS report, which is now under the Trump administration. Climate change
    is like being a smoker with respect to smoker’s cough. Some days when
    the cough isn’t so bad we can deny there’s a problem. The field
    scientists actually see firsthand evidence of methane bubbling out in
    many areas, some quite large. While suspect academics argue whether the
    big burst will happen, they ignore death by a thousand cuts! This year
    the evidence of climate change is profound. Even after the La Nina is
    supposedly over, there is a dramatic change in seasonal temps across the
    US, while Australia is cooking. Intuition tells you there has already
    been an enormous change.

    I’m not quite sure why my previous comment hasn’t been posted, but to clarify, I feel McPherson is making new predictions simply to remain seen in the public eye, to appear relevant.

    I thought it was a “review”. What is the difference between a review and a paper? Why would they need to do a review now? A word about extinction. How could anyone possible prove it is going to happen? I’ve seen an explainer article and a paper that says humans will go extinct if they don’t change their ways. It’s 18 months old and the humans have not changed their ways. Not able. I do not agree with GM on NTHE, but I think it’s likely to happen later this century. One thing everyone needs to be clear on when talking extinction is that climate scientists are not the experts on extinction. Extinction falls under the umbrella of biology, so, scientifically speaking, those are the go to experts. I have read plenty on extinctions and I just happen to be reading a book right now that discusses them. It’s by Peter ward and Joseph Kirschvink – “A New History of Life: The Radical New Discoveries about the Origins and Evolution of Life on Earth” Here is a telling quote from the introduction:

    “Many of the great events of evolution cannot be repeated; evolution has had a long period to fill the biosphere with highly competitive and efficient organisms, making it unlikely to repeat, for instance, the Cambrian explosion when all of the basic body plans of animals came into being. But what can be repeated are things antipodal to living and diversifying, such as extinction, or extinction writ larger—the dreadful past catastrophes of deep time, the mass extinctions.”

    “With every molecule of carbon dioxide we pump into the atmosphere we are ignoring the early sirens that rapid rises in carbon dioxide are the commonality between more than ten mass extinctions of the deep past and what is happening today. Those extinctions were caused not by asteroid impact, but from rapid increases in volancanically produced atmospheric greenhouse gases and the global warming they produced. A terrifying new paradigm of mass extinctions has arisen this century: ‘greenhouse mass extinctions,’ a name overtly chosen to describe the cause of the vast majority of species killed off by mass extinctions in the past.” – P.3

    Here is the explainer article about the mass extinction study.

    Humans could be among the victims of sixth ‘mass extinction’, scientists warn

    “The study “shows without any significant doubt that we are now entering the sixth great mass extinction event,” co-author and Stanford University professor of biology Paul Ehrlich said.

    And the study, which was published in the journal Science Advances on Friday and described by its authors as “conservative”, said humans were likely to be among the species lost.”

    Here is the peer reviewed paper.

    Sounds to me like the experts are saying change or die/go extinct.

    The woman who headed up the project is not all there when it comes to logic. The contention that they do not know where the massive release of Methane in the Arctic is coming from but it has not been linked to the Methane Clathrates. Well, she has a choice it is either the permafrost rapidly melting on land in winter or it is from warm waters making contact with methane clathrates on the sea floor. Since that has already been verified by numerous researchers in the past I would choose the sea floor.

  9. An exciting and incredible report for the climate scientists that should know it!
    I know that in this case you do not have any expertise. The impact of this new discovery is extremely important in climate change.

    THE DISCOVERY OF A NEW SCIENTIFIC FORMULA AND HOPE TO SAVE THE EARTH’S ENVIRONMENT!
    A NEW SCIENTIFIC FORMULA DISCOVERY TO CONTROL OF CLIMATE CHANGE!
    (Ee>Ep+E1at) = (E>P+1at)
    What is the most difficult scientific question of global hydroelectric that no one scientists could the answer to it?
    Now the hard global question!
    How can we produce clean energy in a best way by the potential of water Static head in dams & seas that this water pressure can push to the center of planet?
    Answer:
    This is by getting benefit of joint scientific formula (E>P+1at) with immersion turbines method inside the water of dams & seas (Immersion turbines of series and parallel in zero point of opposite forces).
    Ee= High pressure clean energy that is produced by the water power plants in the depth of water via released fixed potential energy of water natural pressure (More than ten meters of water) with new method (Immersion turbines of series and parallel in zero point of opposite forces).
    Ep= Released fixed potential energy of water natural pressure in water depth (More than ten meters of water).
    E1at= Amount of energy that is consumed at a small pump of one atmosphere power is the ability (In the same place of the water power plant in water depth).
    Many scientists believe that the discovery of the formula is unparalleled. Although many still in shock! How this formula has not be discovered by scientists in the world. Answer to a hard question that scientists are searching for hundreds of years and they can control of climate change and stop global warming soon.
    My new formula and new method can change the world and start a new industrial revolution soon. Note: This new solution and this new formula invention in Iraq and Turkey to formally accepted.
    This invention is patented in Department of Justice in Kurdistan of Iraq No. 952/6 on 12/6/2013.
