I've been using the net in various roles—technical, social, and political—for the last 30 years. I'm disappointed that most forums don't pay for good writing and I'm ever in search of forums that do. (I've not seen any Tippem money, that's for sure.) And I worry some that our posting here for free could one day put paid writers in Closed Salon out of work.

Methane

Rate: 38 Flag

The big worry about Climate Change is not some issue of gradual heating, it's how near we are to various tipping points. [Methane molecule] There has been concern brewing that carbon dioxide is just the tip of the Climate Change iceberg. Methane may turn out to be a more explosive problem, not literally but in terms of its profound effects as a greenhouse gas.

According to the EPA's Methane home page, “Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide.” (That's a conservative estimate.)

On Quantitative and Qualitative Change, and Tipping Points

Given what seems to me an overly modest response to the escalating threat of climate change, I have to believe that lots of people, when they think of global temperatures rising, think in terms of what they'll wear or how they'll stay cool. They're used to winter yielding regularly to summer, and they figure since they survive that rhythm, a shift in global temperature will work likewise.

To understand the serious nature of the problem, one must look past such matters. One must think in terms of larger systems and processes and in terms of the qualitative changes that can happen happen to them. By qualitative shift, I mean a shift that is not just a matter of degree, but of something more tangible, more structural. For example, it matters a little when temperatures go up or down a degree, but at some point what really matters is that you need to put on a jacket or coat, or take one off.

As another example, consider that if you're standing on a frozen lake, having the temperature go from 0°F to 20°F may not affect your ability to go skating much at all, but going from 25°F to 35°F may make a big difference, since you're crossing the melting point of ice. Any given shift of a few degrees is a quantitative shift, the shift from ice to water is a qualitative shift. The qualitative shifts are the things to watch.

Of course, some qualitative shifts are undoable. Winter comes and we all put on our coats. Summer comes and we lose the coats and start looking for swim suits. But sometimes a shift is very hard or impossible to undo. Such dramatic qualitative shifts are referred to as tipping points. They are not only something to watch for, but something to actively avoid.

The Tundra

For example, if there is a place in the world where things are typically frozen all year and the temperature goes up just enough that it's no longer typically frozen, that matters. It matters especially in the arctic tundra.

Hundreds of gigatons of methane are locked in the frozen arctic tundra, laboriously stockpiled over millions of years by various biological processes. If the permafrost melts, which may happen faster due to rapid melting of arctic sea ice, and that methane is released, later re-freezing won't recapture the methane. Worse still, the methane released may contribute to feedback effects that raise temperatures even faster.

The BP Oil Spill and the Methane Problem

Recently, reports have circulated suggesting the possibility of a super-tsunami caused by the sudden release of a giant methane bubble from the BP oil spill. I haven't been able to track down any credible sources that are backing that particular theory, so, at least for now, I'm not stressing about that.

However, that doesn't mean there is no methane risk, though. Levels of methane in the ocean have been measured that are 100,000 or even in some cases a million times higher than normal, according to measurements made by Texas A&M and reported by Reuters. A great deal of this methane remains dissolved in the water, but these rising levels risk creating dead zones where undersea life cannot survive.

And lack of trust in the gulf as a source of seafood is likely to drive up seafood prices elsewhere. That's unfortunate, since among other effects, it probably means people will eat more beef. And cattle are already a key source of methane. We should be eating less of it, not more.

It's Time to Care

The world is heavily very interconnected. We sometimes indulge the luxury of assuming these issues are separate, but they are not. The climate, environmental degradation, the food chain—it's all interconnected. We need to start caring more. The BP oil spill should be a wake-up call both directly because of its effects on the food supply and methane emission, but symbolically because it shows how rapidly things can go downhill for lack of caring to our precious world. We point to the sea turtles and the polar bears, and it's very sad, but what's often lost is that we could be next. These are the canaries in our global coal mine and they're sounding the alarm.

For all the economy and health care have been important, they are just a warmup for the real problem the world is facing. Like the financial collapse, ecological collapse could come suddenly as they did in the gulf. We need to be preparing better.

A small number of degrees of change in the world's temperature could be a disaster. See the movie Six Degrees Could Change the World if you need help visualizing that. The next airing is July 22, 2010, but they re-run it periodically.

I heard one scientist say recently that Al Gore is a bloody optimist when it comes to global warming. Historically, an ice age can actually come in as little as ONE YEAR. In other words, it starts snowing, and it never stops -- particularly if something like global warming turns off the Gulf Stream.

Many scientists say that we have about ten years before the effects of global warming begin to kick in big time, and some scientists have estimated that under conditions of full climate change the earth will be able to support about 5% of the peak population for the planet, which is anticipated in about 20 years.

I suppose when that happens, then perhaps the climate deniers and oil companies might admit that there's something to this global warming stuff.
How to control the mathan you did not suggested.
What to say? Even I had to wait to come and read. I saw a piece in The Daily Beast this morning about politicians trying to fight for fuel sources staying exactly the way they are. I couldn't bring myself to read it word for word. I thought I understood some of the ways our government worked. I did. I do. I don't have solutions and I am sure you are laughing as you read those words from me because you immediately blow holes right straight through something that seems possible to me. You do it gently and I appreciate that.

Money. All seems tied to money. Who will grease my palm well enough to keep me in office? What is their price? Oh, I can do that. Have them sign the check. Morals? Ethics? Of course I have them. Had them. Once. When I was young and before I wanted to run for office. To help my fellow citizens.

Campaign Finance Reform? I have lost track. Has anything pretended to happen on this? Until it does, until politicians can stand on their own independent of bowing to the lobbyists who pay whatever it takes to silence criticism of their particular bailiwick, what will really change?

It is politically correct to care about the environment, but if true, honest caring means I need to leave my car at home or not turn on my electric whatever, what comes first - the environment or my pleasure? Are we really listening? People continue to be surprised by what is happening in the Gulf. They continue to be horrified as the catastrophe creeps closer to them. It began to creep close to all of us the day it began. There are no real surprises except that when faced with such enormous catastrophe, no one really knows what to do. Action can be taken. Band Aids can be taken from the boxes. Will any of us still be alive when things return to what we knew? Will things that have been tarnished by such incompetence and lack of care, regulation on everyone's part ever be what they once were and what we all so took for granted. Shareholders are the only people that matter. Profit margins must be maintained. On and on and on.

Methane. I don't know that I have read anything about this though I have seen reports about possible dead zones being created.

Part of me has thought that nature has her cycles and possibly we are in one right now. Well, possibly we are or would have been had we not managed to personally skew the rhythms of nature toward self destruction. I so hope I am exaggerating here. I so hope things are not as bad as I fear. No wonder I waited to read your piece today, Kent. Can you offer some light?
I followed your link, on that tsunami story. It is indeed frightening, if by any fact it is true.
Regarding the methane connection. I had recently read a book " Six Degrees" which talked much about the methane connection with Global Warming both now, and in the distant past. The scenario was frightening. It also talked about methane hydrates under the seafloor. Which brings us back to the Tsunami scenario. I hope to read more on this subject!

Still abashed at what is worldwide wonderment over a simple theory, I look to the folks like yourself who have taken it upon themselves to really Do something in the way of helping others GEt the picture.
Thank you for this brave step.

Good post Sir! Rated and passed on. What a CRUCIAL issue (to say the least).

I am in full agreement with the other posters (and surely, those to come) that it is ENORMOUSLY depressing to have so much ambivalence toward this important topic (by tea partiers, republicans, whoever).

Still, thinking that this problem is due to stupid, irrational, or ignorant PEOPLE (as if people are not a product of their circumstances) will never get us to the heart of the matter.

Badmouthing people isn't going to do anything...LIVE BY EXAMPLE!!!!! (eat less meat...etc.)

Have a nice afternoon everyone...

Bonnie, I'm glad you enjoyed the post. If it just raises some consciousness (or recruits some people to echo the call), that will be good.

Lefty, see my article Climate Change Coming “Faster Than Expected” where I discuss why I think this is coming way sooner than people think. My arguments are not mathematically rigorous, but I explain at least why they are necessarily without such foundation and nevertheless not baseless. There are times when informed guessing is warranted, and I think this is such a time. The article is a little stale in some ways, has some superfluous bits, and needs to be dusted off and re-done. I'll try to get to that one of these days soon.

Naughty Boy, I didn't suggest how to control the methane. The first step of this major problem is a serious public discussion and some gap-filling in any data needed to convince everyone that this is real. There needs to be centralized debunking of any claims that this is not a real phenomenon in the same way that we would prosecute a war. And then we can work out the strategy forward. But a lot of this will not be easy and cannot be done by individuals just eating fewer cheeseburgers. The problem is both bigger than that and more important than that.
I have read Kent that the methane is more dangerous than the oil itself.

The methane in the permafrost is very very dangerous. From what little I can remember from studying the ice cores (not much) too much methane can be the tipping point that pushes the climate into one extreme or the other.
This much methane is very dangerous to the planet and the weather. I do remember the prof emphasizing the dangers of the permafrost melting. This could be the biggest and the fastest weather swing in recent history.
This oil disaster will affect us all. We all live in a circle here.
Anna, I am anything but laughing and always heartened when anyone takes the kind of time that you do to read about things and to care. But I think what you express about the discrepancy between how we think/wish things worked and the way they actually work is the heart of it. The present system is a sham. The question is what to do about it.

The minimum thing, as you rightly point out, is to get in a politician who doesn't care about special interests. Strangely, I think we did that. I honestly don't think Obama is manipulated hugely by special interests. I think he leans too heavily on certain people he thinks he's vetted and that sometimes special interests creep in there, but that's always a risk. I think his real problem is that he simply thinks this problem can wait somehow at bay while he deals with others, and that this problem ultimately requires modest solutions. At the heart of it, I think the problem is that what got him to office is that he's a middle-of-the-roader and so he hasn't got it in him to fight for this. I think the Democratic party should be fielding someone to challenge him, and they should be telling him not to fight it so that the party doesn't fragment. But they're not. And that's going to be very bad. Not worse than what the Republicans will offer, but what's hard to see is that it's clear the kind of deregulation the Republicans and Tea Partiers want is deadly. This problem will not resolve itself by a wait-and-see or hands-off approach. And yet there are many ways the Democrats can also offer a deadly approach. The Democrats are the most likely to change this.
Kenny, I have no doubt there are bad scenarios related to the possible methane lake there. The mega-tsunami story is good for raising eyebrows but I think it's a distraction and not the right thing—I mentioned in mostly in hopes people would see I wasn't going there. To go back to the financial collapse, there's an explanation in Michael Lewis's excellent book The Big Short where he explains that the people who bet against the market originally thought they were betting on home prices falling through the floor and still thought it a decent bet, but they knew they were golden when they realized that to “win,” (they would win while we all lost) that didn't have to happen. All that had to happen was for the rate at which housing prices were rising would not be as steep before homeowners trying to pay their mortgage on profits from their appreciating home could not keep up. That is, if housing price rises fell to (I think they said) 7%, still a tidy profit, they would still win financially. They knew this would happen. And that's the analogy I'm trying to raise here.

Yes, maybe in some remote chance a methane bubble will wipe out Florida in a single supersonic burst. Maybe. I doubt it. Saying it just makes people shrug and think you're talking science fiction. It's either going to happen or it's not, people won't plan on that. But it doesn't have to be that bad for the entire planet to cook us (figuratively at least, maybe literally). It can involve a much more plausible scenario of a smaller amount of methane (something we can conceive of easily given how much oil is leaking now, and invisible methane wtih it) getting to the surface and into the atmosphere. We have to make a credible case for believable scenarios and not raise fantasy stories that just cause people to tune out.

The Russians incidentally have offered help with submersibles they say have worked at such depths successfully and they say the US is not asking for help.
Poor Woman, I'm glad for anything I can do to help with the visualization. The only brave part about this piece from my point of view was that I felt like I didn't have time to do all I wanted with it, but I just ran it out in what I felt was unfinished form, just to get the word out. I think people have to just put in what they can sometimes to move things forward. The world doesn't always let us do everything, and we have to rely on others to fill in the gaps.
As always excellent work, Kent.

I might inject that a factor involved here may be lack of science education and interest in the U.S.
David, I agree with you that this is an issue we all must confront. Note that I am critical of Republicans and Tea Partiers because their stated agenda is less regulation, to assume the problem will work it out. That's not me bad-mouthing them, it's me calling out a strategy that has been shown to be every bit as bankrupt as the communism they like to (improperly) paint Democrats as offering as an alternative. There is a lot of distance between "no regulation" (or even "less regulation") and a communist state. Thomas Friedman, in his excellent book Hot, Flat and Crowded goes to considerable effort to show how the market can really act positively, but at the same time he notes (and I think very properly) that the market will absolutely not do the right thing without being programmed to do the right thing by appropriate incentive structures in the forms of benefits and taxes. What's bankrupt about the Republican/Tea system is that it presumes taxation to be bad. The best way to say what I'm saying is “Tax what you don't want people to do.” And the problem with “don't tax anything” is that you're sending the message “do anything, do everything” which is not the right message. We need to clearly mark with taxes and outright prohibitions which things we want people to avoid, and we need to clearly mark with tax breaks and grants and other incentives what we want people to do lots of. We're doing a little of the incentive part, but we're also allowing too much status quo by not putting the penalties in the right places.
Mission, yes, that's right. The tundra is a problem and it's going to be aggravated by the arctic cap disappearing faster than people expect, which will suddenly make warming go faster. This is called the albedo effect, and it's surprisingly easy to understand (sufficiently so that I feel confident describing it):

Polar caps are white, meaning they reflect light in all wavelengths, much of it back out into space, and that means the earth stays cool up there. If the caps melt, the ocean is blue. That means that a bunch of light is being absorbed, not reflected, and that means energy is being stored in the ocean. Energy translates to heat. And so the earth warms. Unevenly, mind you. The heat is trapped in the ocean and doesn't initially hit the air. But it means that things that expected to be cooled by the arctic aren't, and so they stay warm. And that propagates through the system.

When it propagates, the arctic won't be as cold and the permafrost will melt. And then the bad release of methane in that frozen ice will occur. And that will make the atmosphere act more greenhouse like, increasing warming. It's a bad cycle. The oil spill makes it worse by increasing the methane availability. Not all of that methane may get to the surface right away, but it might later. There are a lot of unknowns. But perturbing the system seems ill advised just now.

At minimum, I think taking moratoriums on new drilling of this kind seriously is wise. Whatever the case may be for oil drilling, I don't think you'll be seeing any headline ever in your life saying “global warming found to be radically reduced by recent deep water oil drilling.”
Liberal, you're right that shifts in science education would help. Sadly, that may soon be to the point where it can't be usefully done in time to avert drastic changes. That's not to say don't do it, but politically strategies must be devised that acknowledge and accept this weakness, rather than fighting it. (I think this was part of David Logan's point earlier.)

I think that some of the problem with science education is simply not caring, which is sad. We have left our schools in simple disrepair. But there is also an active campaign against being well-informed that is being mounted in a bogus attempt to separate science from religion. I don't think these two have to be in tension with one another, certainly not to the degree they are. I think that certain selfish people, grabbing for power, are doing two things: (a) taking advantage of those not well-schooled, and (b) fearing that science cannot be controlled (weird for scientists to think, since they can't probably understand how something can be controlled unscientifically, but think like a fiction writer: you can shape some things in your story but not the physics. If you're a politician trying to spin a fiction, science can derail you. So the less science, the more any given spin will work...)
There you go making sense again. My opinion after the response of so many "Fearless Leaders" to the gulf gusher that we need to continue to drill in deep water without finding a way to do it safely, has finally sealed some of my thoughts that I've suspected for a long time and that is that we are so screwed.

You can't put five politicians in a room and get them to agree on any part of global warming or anything else. There is never going to be much of a green energy initiative because it will never be seriously discussed. The temperatures will continue to rise and polar bears will be walking down Pennsylvania Avenue and still there will be people who refuse to believe or admit that humans created global warming.

Politicians will still be whining about the taxes their grandchildren might have to pay for cap and trade. About the only way I see to save the human race is for everyone to quit breeding for two generations and start all over again in fifty years. But of course, that is bad for business. I think it will take something that drastic to make much of a difference, otherwise, this game is over.
Michael, thanks for visiting. Yes, we are in a bad state just now. My personal bet is that we don't have nearly enough time for your proposed strategy. I'm very bearish on the whole thing and expect it sooner than everyone expects. Arctic ice gone within this decade, perhaps by 2015, catastrophic problems by 2035, with plenty of in-betweeen. But I don't give it even the 100 years that many pessimists do. That article I cited is my best attempt so far to explain why, but I'll try to tighten it for republication sometime in the near future. It's getting to be time.
Great post and all too timely a message Kent. If, through painful experience, I hadn't become jaded and cynical about the public's attitude to the peril of global warming, I might have expected that a looming but avoidable calamity threatening widespread death and destruction would have concentrated enough minds to take the necessary steps. But the difficulty in preventing global warming is small beans compared to the difficulty of overcoming the greed, tribalism and willful ignorance that makes this disaster almost inevitable.

Perhaps the homo sapiens branch of hominids is just imbued with too many imperfections to make a long run of it as a species. Still, it's worth the try. I hammer on my friends who are partly skeptical and do what I can politically. If enough people do what they can, maybe soon we can get some real cutbacks on carbon emissions. I'd be much more despairing if I were in my 20s instead of my 50s.
Abrawang, I think the reason the people in their 20's don't care is that it's been portrayed that we have another 100 years and they imagine it can be put off. I think they don't have that much time, and if they knew, they would care more. But youth often prefers to procrastinate about serious matters if possible. What's allowable here is elusive to some, though, and that's where the trouble comes.
Maybe there's a way to capture and utilize the methane released from the thawed out tundra. The higher temperature might enable the growth of new vegetation on the former tundra to capture some CO2 also. Lots of well ventilated greenhouses...
This is a technical question and I don't intend to be a wise guy but do you know how dissolved methane can produce a dead zone? I don't know why that would happen.
Nice work!
hatchetface, I know exactly what it said in one of the articles, which is not much. But if I read it correctly, it sounded like it was just a matter of so biasing the parts per million that as a relative number, oxygen was just proportionally too little to be productively obtained by fish. In effect, I think, the effect is similar to how people can suffocate from nitrous oxide... I don't think it's per se toxic (though I could be wrong about that), I think it just leaves you starved for oxygen if you're not careful about the delivery (as people under its influence sometimes are not). But this is just a guess and I'd welcome correction from someone who understood this stuff better...
Thanks. I will be a wise guy here and say that I thought it was something like that. Not enough room for everything at constant pressure.
"The climate, environmental degradation, the food chain—it's all interconnected." Yes, and connected to the economy and national security too. Thomas Friedman is indispensable on this subject. The Europeans are way ahead of us on this. Even the Chinese, hardly models of environmental stewardship, are coming around. We need to get on the bandwagon now. Excellent piece, Kent. Well researched.
Hi, Canuck. If you run out of links on this matter, try my archive of climate change press clippings. :)

hatchetface, I guess it wouldn't sound right for me to protest that you're not wise at all, so I'll just let the comment stand. Heh... But yes, your summary looks right.

Steve, thanks for visiting. I agree with you about Friedman. His writings are quite important on this topic. He's a clear thinker and has a lot of good ideas.

Karin, we need more scared people, that's for sure. I don't want people to panic. But they have to not just forget or dismiss things.
a good recap of a critical issue. but the problem isn't physics, it's politics. the gulf oil is a present demonstration that rule by politician has created the possibility of extinction. it may be that humans have been bred for submission for too long, and can not forge a system to respond to the damage done by the greed and arrogance of alpha males.

about 95% of earth's species are extinct. we might join them soon.
"We point to the sea turtles and the polar bears, and it's very sad, but what's often lost is that we could be next"

I doubt if humans will go extinct as such. It's just that our civilizations will come crashing down, reducing our population to a tiny fraction of what it once was and leaving the survivors in a state similar to the people in Cormac McCarthy's "The Road." It will be a restoration of balance after massive overpopulation and its resulting environmental degradation, and is easily predictable from a basic knowledge of how ecosystems work. It's not a question of if but when, and the when is looking sooner rather than later.
I hate to go here because I usually end up being misunderstood, but what the hey :).

My view is a little unpopular because I'm in the camp that accepts that global warming happens, it's part of the planet's natural cycle, we can not stop it. But I do believe that we are likely accelerating the process with our actions.

My view point is also unpopular in that I simply don't accept that we are going to destroy the planet, the planet will go along quite well apart from us (so long as we don't figure out a way to split it from the core out). What we will destroy (and this is similar to Bonnie's comment) is ourselves, we can destroy the environment that supports our form of life. But not the planet. Splitting hairs I guess, but it bothers me that we don't make the distinction between destroying ourselves and the hubris of thinking we can destroy the planet :).

That said. I appreciate this piece for the simple reason that people need to wake up and *prepare*. I'm not at all sure that *repair* is possible no matter what measure/s we take - but if we are going to survive we need to be thinking about what it's going to take to do that with regards to any case scenario.

To that end this is a good, thoughtful, reasoned read. It is to be hoped that folks listen and begin to think about it, whatever their personal view point might be.

Rated for need.
al, you speak as a detached outsider. Make some suggestions, not just always criticisms please.

Nana, what makes you think we'd survive at all?
Seer, I think when people speak of the planet, they speak of a “planetful of people” and they intend the species. I don't think anyone thinks that the planet will disappear. After all, the other planets exist even though lifeless; Venus exists even though obscured by greenhouse gases. But yes, we're vain enough to think the planet is about us, which is perhaps why we're foolish enough to think it can't happen. It's almost as if the deniers think that there's something about the world or the Universe that cares enough to save us from ourselves. That's a dangerous expectation.
We're nearly ubiquitous on the earth Kent, like cockroaches, and we're too adaptable a species to be killed off by climate change alone. The effects of it will be more pronounced in some areas, less pronounced in others, and there will be isolated populations of homo sapiens who'll manage to survie, either via subsistence agriculture or a reversion to a hunter/gatherer level of development. That's just my own take of course, and I may well be wrong.
To elaborate a little; we picture humanity as synonymous with our civilization, with the accumulated mass of our cultural and technological advancements. We're not though. We're a species of animal, and a very adaptable one, and we survived for tens of thousands of years through extreme climatic shifts without agriculture or technologies more advanced than stone tools, skins, and fire. We can do it again, but it'll be hard to find a decent cabernet.
Kent,
I love it when your intelligent and cogent articles make the cover.
I think you are right about the attitude shift that needs to happen on an individual level. When I was a research assistatnt for a book about the social construction around climate change, it was the attitude of the populace which drove their country's policies about Climate Change. If the people did not care, the nation ignored the issue.
Thanks, Kent, marvelous piece.
Nanatehay, I'm not saying it's impossible. I'm saying there is not a firm foundation for betting on it. It could just as easily go the other way. Those are not good enough odds. The importance of civilization surviving, collective memory intact, is not to be understated.

o'steph, thanks for the support. The difficulty is figuring out what people need to know and how to present it so that it's intelligible and motivating. I keep trying it from different angles. Without a clear public mandate, it's hard for politicians to care.
Kent, I didn't know how serious a role that methane plays in the climate change situation as it is carbon that we hear about the most. Definitely a tough situation to turn around given our patterns of day to day life, etc. Regarding the problems added if more people turn to eating beef, you also hit the nail on the head. As you mentioned, not only are cattle methane producers, but it takes so much food, such as grain, to feed a cow just to eventually yield some meat for the consumer.

Thanks for a thoughtful and well researched post! With luck each of us can find some serious ways to change our habits for the better of the planet.
designanator, I'm always glad to hear I've opened the eyes of thoughtful people. Now get some more people informed. :)
I'm going to go sit in the peace and beauty of my garden now...at least until 10 or 10.30, when it becomes too hot...

Sometimes I think the U.S. is a barbarous state, Kenghis Khan of corporatism...but, aside from (apparently) some nordic countries, the whole planet (haha, meaning the human biomass) is like that... Plus us innocents, who *carry on* because we don't know what else to do... (I don't eat beef, I A/C one small room and only at night, have always lived modestly (by first-world standards)...except for recent travel... Oh well, garden here I come.

P.S. - Must look into what, if anything, Canada, occupier of great expanses of permafrost, is contemplating... What from Russia? As for Alaska, I see drilling will now be permitted in thousands of square miles...
There are several factors in the stew. Beyond the frozen methane in the tundra there are huge stores of the stuff under the ocean and if the ocean warms it will rise to the surface.
Once the crops start to fail it won't be a matter of people struggling to survive, there will be major wars to gets what's left and I have no idea how vicious it may get with huge bands of starving refugees and execution squads to keep them away.
Humanity is and has been suffering from the disease of money raping the planet for a long time (see http://www.counterpunch.org/stclair07092010.html ) and things are finally edging towards a breaking point.

At 84 I will be hopefully dead when the full impact hits as it certainly will.
Thanks, Kent. This is an issue I knew nothing about.
thanks for your very important essay on this subject, your example of a frozen lake perfectly illuminates the "tipping point" concept, I hope you'll follow up with discussion of the likely consequences of crossing such a tipping point, as a biosphere we have living feedback systems that could quickly recover from the imbalance of carbon dioxide in the atmosphere, I'm not sure that such mechanisms exist for coping with a large release of methane

the scientific consensus represents the most conservative estimate of how global warming will affect our environment and civilization, and is most often not extended beyond the end of the current century, every year the predictions of that consensus grow more dire as we march from the hypothetical to the concrete and measurable, all the while ignoring what this change means two hundred, five hundred, a thousand years down the road

I agree with nanatehay that humans are likely adaptable enough to survive as a species, but a massive population crash is probably inevitable, my question is how much of the accumulated store of human knowledge and expertise is likely to survive, how much of the global infrastructure will a drastically reduced population be able to maintain? I have a depressing vision of a scattered human population of a few millions living underground around the margins of the Arctic, scrabbling a living from an impoverished and uncertain agriculture, desperately trying to preserve some fraction of our hard-won common inheritance through millennia of hell on earth
Firestorm, I think you're missing a point. Research and conclusions don't really matter. The thing is there is clearly a problem (many of them). Anyone who cares enough to give these problems thought is a step in the right direction, whatever kind of step they take :). We can give our differences in results some attention later, but we first have to stop looking the 'other way'.

Whether you agree with Kent's information or not, at least he is *looking*.
Kent, I agree with you that things are probably worse than our actions (or inaction) would suggest. (And please forgive me if I tread ground already trod as I don't have time to read through all the comments.)

During our particularly cold and snowy (!) winter here in the Deep South, I argued with quite a few people I know who pointed to these abnormally cool temperatures as evidence that the planet is NOT warming. I was genuinely overwhelmed at the magnitude of ignorance about this topic conveyed in their laughing denials. I explained that an increase in the planets average temperature is predicted to bring about unstable weather patterns, patterns that tend toward extremes but they didn't even argue the facts with me. They just pointed to those now debunked "smoking gun" emails that claimed a climate scientist was misrepresenting data.

Now that we are having a miserably hot summer, with temps topping 90 degrees back in May and climbing ever higher, should I ask them if they have changed their opinion on climate change? No, because it won't matter. When there are active and ongoing campaigns by the media, elected officials, political parties, religious organizations, and just about every other "voice of authority" to undermine science and reason, we can't expect people to listen to science and reason. The public has been captured by the propagandists and I'm at a loss as to how we can go about undoing the damage.

Oh, and Adam and Eve rode dinosaurs. But you already knew that, right?
Oh, and if the tsunami theory turns out to be more than someone's uninformed fantasy, it's been nice knowing y'all. I understand Jackson, Mississippi won't even be beach front property. Although I do live on a bit of a rise near a river. Maybe I'll have my own island!
Myriad, I don't know the Canadian position is on the permafrost. There are a fair number of Canadians who post here. Maybe someone can comment. On the other hand, it's not really a national issue. There is, I suppose, the slim risk of one of those methane bubble issues which might be a local effect, but for the most part I think the risk is to the world, not the local region, and the causes are things going on around the world, not just in the local region. So in a sense, they have no more or less stake in it than anyone else. It's not like they can build a giant refrigerator to keep things cold. Well, mostly not. Maybe something like this could work.
Jan, indeed, my recollection from high school chemistry is that gases often dissolve better in cold water than in warm water (the reverse of many solids, like salt and sugar, which dissolve better in hot water). It certainly seems to be true of Methane. A solubility graph is here. This means that as the oceans heat, less methane can remain dissolved. I assume that means it will be headed toward the atmosphere. Or that may not be true of the permafrost, which may be locked up in other more complex states, but it may be true of the methane dissolved in the gulf. I'm not a chemist. Maybe one will chime in.
Roy, methane doesn't stay in the atmosphere over the long haul. It decays after a few years, so it doesn't build up easily (except if there is a regular supply), but unfortunately it decays into CO2. It still has short-term effects that can be damaging, and all that CO2 it leaves behind is not better. There's also some risk (as with the ocean dead zones) of atmospheric suffocation (as has been documented to happen even with CO2), but that is considered by most people I know to be unlikely on any large-scale basis. (It nevertheless is the basis of stories like the one about the super-tsunami, which probably won't be the last of the scare stories). The real danger of the methane is that its release speeds things up. We're already warming too fast and each of these trigger points makes things much worse. It matters a lot to not hit them because it keeps us in the (comparatively) slow zone. Then again, we could do a lot for methane production to just switch to farming and eating kangaroos in place of cattle. Cows are already a huge source of atmospheric methane.
Rob, I'm glad you got something out of the piece.

Aaron (Firestorm), I responded to your critiques on your thread so I won't duplicate my response here. I was disappointed that so much of your comments were personally directed at me. I had no real problem with the technical/scientific observations you were making. What's funny (and a bit sad) is that in response to my Corexit post, I got commentary from hatchetface which was really of similar character to what you wrote. That is, it added considerable detail and came at things from a more technical angle. His remarks were offered as helpful—in truth, he was much more kind than was necessary given the degree of disagreement he had. But the point is that by offering his remarks “in stride” it led immediately to an interesting discussion that I think offered more light than heat... in contrast to your critique, which gets lost in the heat. Oh well. I certainly would encourage others to read your remarks if they don't mind picking through the critiques of me to find the technical points.

Seer, thanks for the supportive remarks. Yes, this is just offered as one of many points in a dialog. If all it does is help people to understand why predicting the future based on the past, it's a step forward. People see the temperature rise a couple of degrees and say “no big deal” and think that's proof that another couple of degrees will be the same. They need to see that it might not be. Even if I were wholly wrong here (Aaron disputes a lot of it, and some of his arguments seem sound, while I question others of them), it matters that people see the questions as urgent and they start caring about dialog on these matters at least as much as the tabloid fare that seems to occupy our time and energy. In retrospect, I bet we'll all wish we'd used our time differently.
Susan, yes, it's infuriating that people are so able to claim statistical superiority from a single datapoint where scientists are really tracking this stuff very closely.
A nice piece, well written and researched. Thank you.
This is good....but for some unknown reason i wouldn't go and put the methane problem all on the cow's shoulders pigs make a lot too
and a person would think since we could put men on the moon that we could come up with some sorta idea to collect and use all this gas
thats just hanging out (just me) as the rest of "global warming,climate changeing (ect) could all this just be a reaction to a action with this tumbleing rock we all live on? how long have we abused "mother nature" i'd say she's about pissed putting it lightly
but there are more points and reasons the list goes on an on
lol but say blame it on oboma....he seems to be doing a good job of messing things up this wouldnt matter to much more
Very interesting and well-written post, and from a point of view that I had not seen before.
It's worth noting that the Associated Press is reporting that a methane leak near the recently capped well is probably going to be reported. The magnitude is not yet known. CNN is also following the emerging story.
There is nothing I can add to your thoughtful post save for a quote from an "ignorant savage":

"This we know: the earth does not belong to man, man belongs to the earth. All things are connected like the blood that unites us all. Man did not weave the web of life, he is merely a strand in it. Whatever he does to the web, he does to himself. " Chief Seattle
Gianna, thanks for the support.

Bubba, yes, pigs, too. I certainly wouldn't blame this problem on Obama—it's a problem of global scope and what's mostly holding it back is the public will to fix it. I do wish Obama would push harder, but it's not just his fault he's not.

Mishima, hi, thanks for visiting. Glad to do a bit of consciousness raising.

Tom, thanks for dropping in and for the good quote.
kp, here's a practical suggestion: stop doing things in the same old way. sign up with 'initiative for democracy.' tell every democrat politician on the first of every month that you want citizen initiative and won't vote democrat till they establish it. then use citizen initiative to do what no politician dares to do.

which is run the nation 'for the people.'
al, I don't know if it would work or not, but it's certainly constructive in that at least it's something people can do if they choose to. Thanks. :)

By the way, I'm assuming you're referring to The National Initiative for Democracy?
