Warmer Pacific Ocean Could Release Millions of Tons of Methane
vinces99 writes: Off the U.S. West Coast, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these carbon deposits to melt, releasing methane into the sediments and surrounding water. Researchers found that water off the coast of Washington is gradually warming at a depth of 500 meters (about a third of a mile down), the same depth where methane transforms from a solid to a gas. The research suggests that ocean warming could be triggering the release of a powerful greenhouse gas (abstract).
Scientists believe global warming will release methane from gas hydrates worldwide, but most of the focus has been on the Arctic. The new paper estimates that, from 1970 to 2013, some 4 million metric tons of methane has been released from hydrate decomposition off Washington's coast. That's an amount each year equal to the methane from natural gas released in the 2010 Deepwater Horizon blowout off the coast of Louisiana, and 500 times the rate at which methane is naturally released from the seafloor.

One must note that environmental science is best at observation, and typically poor at prognostication.

I've stayed clear of the whole climate change (or whatever you want to call it) debacle for the last decade, since it has become so politicized.
I don't have enough field knowledge to combat every ridiculous claim, coming from either side.
From what I understand, there is little doubt climate change is happening, the questions is to what extent the impact of humans may be responsible.
Is there any solid evidence for this? How reliable are the models? How can we have a reliable answer when we haven't been recording data for long enough?
I would appreciate a simplified answer with good citations. If the IPCC report is not sufficient or is incorrect, why?
If you ignore ACs because they are anonymous - you're an idiot.
When the Methane clathrates melt in sufficient quantity, you can all kiss your happy lives goodbye.
Time to act was 20 years ago, not to proceed ahead at normal rates like we have all the time in the world.
I am angry, upset, and beginning to feel that the politicians who have set us on this doom riden course will all be happily dead in their graves when our grandchildren are cursing their names. (and by cursing, i mean wishing they were not dead so that they could torture and kill them)
Unfortunately there is not enough panic in peoples actions. its all gone on too long. time to start making a list of who is to blame.
BAKED BEANS!!!!

Because man made CO2 is not causing global warming. The sun drives our climate, not CO2. Read the NIPCC reports.
HOW DARE YOU SLANDER MY RELIGION!!!!!
DENIER!
NONBELIEVER!
Yes, he is a believer in the SUN GOD! Long live climate change! Humans are the DEVIL! Their freedom must be taken!
questions is to what extent the impact of humans may be responsible.
No, this is fairly easily measurable; we're dwarfing natural processes. Aside from natural seasonal variation the biggest natural contributor to atmospheric CO2 is volcanic activity, and the rate at which we're releasing carbon is completely unprecedented. You can figure it as equivalent to 1-2 Yellowstone supervolcano eruptions every year, or two Pinatubos per day. (the article quotes from a paper that I belive is available online but I can't find it at the moment).
The models are well-defined on the lower limit due to the physics of radiation; 3.7 W/m^2 increase per doubling of CO2 is a straightforward result of the Stefan-Boltzmann Law. That is equivalent to about 1 degree C global temp, and no one is worried about that. The issue is that water vapor is a much stronger greenhouse gas and you may have noticed that there's quite a bit of it lying around. Furthermore, air can hold exponentially more water vapor as it heats up. There's a lot of variation possible in the feedback loops but negative feedback is really unlikely.
Personally, I find the most useful way to approach the subject is to take a look at the history of climate science. Thousands of scientists did not wake up one day and accept the movement of the continents, neither did they accept that humans could have any affect on the climate without strong proofs. The Discovery of Global Warming goes over the history of global warming and has useful insights into what exactly a climate model is, and how even one-dimensional models can still tell us useful things even if their long-term predictions are not all that accurate
For a more detailed look into the science, you might check out Science of Doom, but a textbook on atmospheric physics may be more useful. Unfortunately, beyond the basics it starts to get complicated in a real hurry; unless you really want to start diving through papers and textbooks you will probably be best served by the IPCC report.

I was gonna suggest this as well. With all the worries about energy sources, why not find out a way to procure it from the sea, and then provide it to energy consumers. Global dependence on oil reduces, and alongside it, one of the causes of global warming get eliminated - both due to less oil being used, and due to the methane being used for energy rather than simply get released into the atmosphere. Same argument about the flatulence of cattle
will be When the oceans fart.
FTA:
Still unknown is where any released methane gas would end up. It could be consumed by bacteria in the seafloor sediment or in the water, where it could cause seawater in that area to become more acidic and oxygen-deprived. Some methane might also rise to the surface, where it would release into the atmosphere as a greenhouse gas, compounding the effects of climate change.
In other words, they don't know what the hell is going on or what's going to happen. It could be part of a self-correcting, natural process, or it could be the end of the world as we know it. Tune back in at 5:00...
Here is the paper I mentioned, and here is the USGS's take on the matter. From what I understand there are a number of ways to estimate human CO2 output, one being to add up all the fossil fuels that are being consumed globally, which is likely not terribly accurate but we're still talking about two or three orders of magnitude difference. Another estimation method uses carbon isotope ratios. I get the impression that estimating volcanic emissions is somewhat difficult, but there's a fair amount of continuous monitoring for various reasons. Terrence Gerlach, a vulcanologist with the USGS, seems to have done quite a bit of research into the subject. The nice thing about scholarly publications is that they have to tell you where the numbers come from; if one wants to find out more about either part of the estimates then you just follow the references.
In summation, parts of the estimates come from direct measurements and the other parts seem to be estimates based on fossil fuel consumption. I am sure that there's a whole world of study out there for estimating various factors.
As an aside, humans are still far from matching or exceeding the most violent outgassings that have resulted from the formation of Large Igneous Provinces. I believe the Deccan Traps and Siberian Traps released about 3 orders of magnitude more CO2 than humanity has liberated. While our current burn rate would have us match those outgassings in about a thousand years, I don't believe that our fossil fuel reserves are projected to last that long. However, Large Igneous Provinces generally took millions of years to form, not hundreds; there is every reason to believe that what we are doing to the planet is unprecedented. On the other other hand, we're mostly skipping the problems with particulate matter and sulfides that came along with volcanic eruptions. For what it's worth.
Those who advocate genocide deserve every protection afforded by law, and none afforded by common human decency.
Humans are 100% responsible is a claim which makes headlines.
But have you read actual research.
It says, there is enough evidence to prove that most of the warming can be linked to human activities.
Science looks at evidence, and then presents a hypothesis. This is how it has been in the scientific method. When an evidence is discounted science looks at new evidence.
Science is never always right. Scientists make mistakes. And that is why its science. For example, some hypothesis about climate change was proved wrong. Does it mean that entire climate change argument is wrong?
Scientists will update their models, gather more evidence and then present the findings again. Being wrong does not discredit science. It merely improves it.
The problem is, people view science as they have viewed faith. There is no room for error or mistakes. So any process which makes mistakes is ridiculed. IPCC has made mistakes, so have other climate scientists. Some evidence may not be relevant or nonferrous. But it does not matter. We just move on.
There are some things about climate we do not understand. That is also acceptable. Sure, faith based systems have all the answers, but that is not science. You first have to understand what is science, and once you do, you will figure it all out.
Do not fear science. Embibe it. Question. But not because somebody told you to, or some rich publication says so. Question on your own merit. If you do not believe something to be true, instead of ridiculing and pointing to some site on the internet which says its wrong, ask the question.
What site X says, is it true? If not, why? You will find answers to all of it if you start looking for it.
But if you let your faith cloud your judgement, you will never understand. If you want to understand, question. Now ridicule.

Nature just fucking proved it.

Any study is valid if its peer reviewed. So first of all you need to apply this filter. You are not qualified to believe in a study. So people like you and me look for peer reviewed studies.
Secondly, you have to understand that a study is one study.
So if 20 sites quote Study X
and 2 sites quote study Y
It does not mean there are 2 studies Y and 20 studies X
Many times, these denier sites all quote one study, and in the cacophony confusion arises.
So whenever you find something, see if you can follow the breadcrumbs to the source paper.
Find if its peer reviewed.
Then store it.
Collect a few such papers. You will realize that the papers supporting human cause will vastly outnumber those opposing it.

Okay... What part of "naturally" is this not? Summation of the article for those who TL;DR:
"Because of the changing nature of nature, the naturally occurring sequestration of naturally occurring methane as naturally occurring methane ice is naturally changing. We can't say for certain whether the changing nature of this is because of nature changing or because of AGW but because we don't have the historical records of the natural cycle to compare with what we are currently observing, we are going to classify this change as unnatural, since we naturally can't tell what nature is doing."
ARGHH! Bad non-thinking environmentalist! Return your Grant money!
"...The warming water probably comes from the Sea of Okhotsk, between Russia and Japan, where surface water becomes very dense and then spreads east across the Pacific. The Sea of Okhotsk is known to have warmed over the past 50 years, and other studies have shown that the water takes a decade or two to cross the Pacific..."
So, nothing to do with CO2, global warming or fracking, then?
FINalllyyy..... someone gets it.
Methane photooxidizes with a half life of ~21 days in sunlight at average insolation. It gets released and then breaks down harmlessly and naturally. So much for methane for being some "super toxic greeeenhouse gasss!11111!!!"
... instead of "climate change"...
When is this shit going to end? How many corrupt, lying dirtbag 'scientists' are involved in this 'climate change' gravy train? Hopefully we can try them all and imprison them for life, when this shit is over.

etc. There is no such thing as 'catastrophic man-made global warming'.
"Maybe", "could", and "expected" are the keywords here. A really bad thing might happen with a very low probability. Meanwhile, we are asked to make very certain sacrifices — surrender both money and rights to the State.
No wonder, Statists love it, and scratching a "global warming" alarmist always reveals a Che Guevara T-shirt underneath...

Sadly if we abbreviate save our backsides we end up with SOB which just won't work well. Maybe a word that means the same that starts with an A would help. We'll call it the SOA association. In order to save our A we need to consider just what actions to take. One is to use our minds and the other is to sit back and quietly wait for science and technology to save our A. My humble, adled, mind suggests that using our brains is more reliable than waiting for tech to bail us out. Therefore the issue is simple. Pollution is a result of human activity. This includes heat as a pollutant. The more humans, the more pollution. That is very simple to grasp. Less babies means less pollution. Knowing that does very little unless we have enforced, birth control. We have reached a moment in time where many people should not be allowed to reproduce at all and those that are allowed should be limited to one child in one marriage for life. Doing this will reduce world population until we get to a level at which the consequences of human activity have very little effect upon the planet.
disproven so many times that the amount of ignorance required to believe it is no longer even funny.
If solar cycles were driving it, and they are not, then we should be cooling right now.
There is zero correleation between solar cycles and the warming trend.

Counter-intuitive in the case of methane.
Verbum caro factum est
Every time I am in warm water and especially the shower, I release large quantities of methane along with sulfur compounds.
I know the methane clathrate gun hypothesis was disproven, but the difference between that and this becomes academic beyond certain amounts of warming.

"First, what's pretty definite about the Permian Extinction is that a really big meteor hit near Chicxulub, in the gullf of Mexico, at the right time to contribute to it."
The Chicxulub impact was at the end of the Cretaceous 65 million years ago
The Permian ended 252 million years ago, and the initial event that started that extinction was mass vulcanism, but the methane release added to the CO2 warming, and over 95% of species were wiped out.
If man made C02 emmissions continued at the current rate for long enough then it could happen like that again, some life will survive of course, but probably not H-Sapiens unless we go elsewhere (off of this rock) before it happens.
For those interested, this appears to be the paper. The paper itself is paywalled; you can look at the supplementary material, which includes the diagrams. Oddly, the paper does not seem to be online at the university, even though other papers by the various authors are. Why do I know this? Because I wanted to see the temperature data that they used, so I went hunting.
The paper implies that the temperature data is very noisy, but that they were able to extract a signal anyway. The raw data should be provided in the supplementary material, so that people could attempt to replicate/verify this essential finding. Of course, the raw data are no where to be found. So we have no way to check.
Personally, I'm tired of "science" like this. If you're going to make a claim, put your damn data out there where anyone can see it. Raw data, a clear description of how you processed it, program code if you wrote a program. Otherwise, you're no better than the astrologist pontificating about the influence of Venus on your dog's love life.
Enjoy life! This is not a dress rehearsal.
Because they don't like the solution.

Wrong. The IPCC computer models have been proven grossly inaccurate over and over again while the predictions based on solar activity have been proven correct over and over again.

Starging with your claim that "30 Years ago the global warming people were saying my home would be under water now".
I will not take untestable propositions like that on any kind of faith.
Prove or retract.
Your claim that the IPCC have gotten near 100% failure rate is absolutely wrong:
http://www.realclimate.org/index.php/archives/2013/02/2012-updates-to-model-observation-comparions/
Since the IPCC merely collates and represents the results of those models, the conclusion should be easy for anyone not blinded by bigotry and hate.
And if you're simple minded enough to think that the interaction of an entire planets atmosphere and all the myriad of complex cycles and energy inputs and drains can be compared to a pot or water and fire then you should be given the "special thinker" award of the year.
Congrats you little smarty you...
So it went
You keep saying that, but that doesnt make it true.
First, the Sun:
This is a solar activity compared to global temperatures:
http://www.skepticalscience.co...
Solar activity has actually declined over the past 40 years, while temperatures have gone up.
I'd challenge you to explain that, except you cant. And neither can the people you mention.
And the fact you even mention them shows your level of ignorance.
Piers Corbyn in particular claims to make accurate weather predictions up to a year in advance.
He isnt even a meteorologist. He is a fraud and a conman.
It's not the sun and there is zero scientific evidence to support such a claim.
If it were the sun, then we should be cooling right now. Which we are not.
End of story.
Next the models:
http://www.skepticalscience.co...
Same thing: you're wrong.
The models have been very accurate over time and only gotten better.
The guy who said the election was rigged won the presidency with the second-most votes.
A. We just set a record for global temperature this year.
B. Seattle set a record for temperature this year (and we're the least affected region due to Global Warming, so that's very bad for the rest of you)
C. The amount of methane release will be similar to what it was BEFORE HUMANS EXISTED. As in dinosaurs.
Now, keep up with your excuses for why you're so lazy.

Because man made CO2 is not causing global warming. The sun drives our climate, not CO2. Read the NIPCC reports.
Tobacco companies and others published reports about how tobacco use wasn't bad for you too. The even include some of the same people such as Fred Singer.
So, the freezing point of Methane is -182,5 C and its trapped below frozen underground layers of water. .. does the frozen dirt below the seafloor have liquid water above it?
I wonder
Hivemind harvest in progress..
So the "ice age is coming" of the 1970s becomes "global warming" in the 1980s/90s and has now morphed into "climate change" because the warming stopped 14-18 years ago. "Climate Change" is so nice because they won't have to change their scam's name every time the climate does something they don't expect .... like CHANGE!
For goodness sake climate is always changing and humans for all their arrogance have very little to do with it. CO2 might have a 1 degree C change for each doubling.
A question for everyone who thinks that CO2 controls the climate. How long with rising CO2 and flat or falling temperatures before you admit your theory is wrong? 20 years? 30? Never?
All 5 of the major datasets (RSS, UAH, HadCRUT4, GISS, NCDC) show no statistically significant warming for between 14 and almost 18 years. In that time CO2 has risen 8-10%.
Here are 2 predictions. First I predict that CO2 will continue to increase because China and other countries don't care about CO2. They don't even care about real pollutants much less CO2. Second I predict it will get colder over the next 20-30 years. Why?
Dr Libby in the 1970s said that "looking forward it will stay cold until the mid 80s (it did), then it will warm by about 1/4 degree F until the end of the century it did), then it gets cold". When asked how cold she was predicting a 1-2 degree F drop with an outside chance of a 3-4 degree drop.
Dr Easterbrook in 2001 said the PDO was done it's positive warm cycle and that we were in for 25-30 years of cold weather. How cold? We have his good, bad and ugly predictions based on previous negative cold phases of the PDO.
Why do I join with them and side with their predictions? While past performance is not a guarantee of future correctness it is a lot better record than the IPCC and their dozens of models of which none have been accurate. They are all based on CO2 controlling the climate and the other 2 are all cyclical natural cycles. I'll go with those who have a good track record at predicting future climate. Dr Libby is the most impressive as her prediction is 30+ years going and still accurate.
If you want to read a great explanation of why the IPCC models are broken beyond belief there was a great article describing that and all the other problems with climate science by Dr Brown of Duke university
