I had no idea about this, which somehow makes me feel deeply ashamed of myself. And for that, in some twisted way, I thank you.
On the topic of global warming itself even, just today an adviser was talking to me about the pervasive skeptical thoughts on it in the academic community as few as five years ago. But then he started talking about how we'll probably live to see the extinction of the polar bears and I couldn't help thinking how, on top of everything else going on recently, we're pretty much going to hell in a handbasket.
What? Oh, right.. right... methane, that's what I meant to talk about. Maybe some massive release will help speed things along a bit?

If Mother of Storms is at all accurate, we're up shit creek. In the book the methane was released by a bomb, so hopefully it will be a bit slower. He predicted hurricanes that were powerful enough to cross over Central America and gain more power in the Pacific. Real horrific wrath of god type storms, that were essentially permanent.

The consequences of a methane-driven oceanic eruption for marine and terrestrial life are likely to be catastrophic. Figuratively speaking, the erupting region "boils over," ejecting a large amount of methane and other gases (e.g., CO2, H2S) into the atmosphere, and flooding large areas of land. Whereas pure methane is lighter than air, methane loaded with water droplets is much heavier, and thus spreads over the land, mixing with air in the process (and losing water as rain). The air-methane mixture is explosive at methane concentrations between 5% and 15%; as such mixtures form in different locations near the ground and are ignited by lightning, explosions and conflagrations destroy most of the terrestrial life, and also produce great amounts of smoke and of carbon dioxide. Firestorms carry smoke and dust into the upper atmosphere, where they may remain for several years; the resulting darkness and global cooling may provide an additional kill mechanism. Conversely, carbon dioxide and the remaining methane create the greenhouse effect, which may lead to global warming. The outcome of the competition between the cooling and the warming tendencies is difficult to predict.Taken from this paper

Two things rub me the wrong way about this:

2. It kind of, sort of suggests that drilling all the natural gas out of the ocean is a good idea

Sys Rq: The human causes could be thought of as the finger on the trigger. Certainly, pulling the trigger isn't a trivial act.
And drilling all that natural gas out still isn't a good idea. What's going to happen to it? Where's all that carbon going to go? Are we going to put it in bottles and, I dunno, just sit on it? Nope. It'd go into the atmosphere, and we'd just be further along the track.
So, what's to be done? Honestly, I think it's about fucking time we got on and built some off-world colonies (the chance to begin again, in a golden land of opportunity and adventure)

Well, sexyrobot, honestly, given everything I read lately, your very simple statement is the only thing that keeps me sane. I repeat it like a mantra almost every single time I read any story like this. Honestly, though, sometimes it feels like putting a newspaper over your head in a hurricane. Without being a scientist, I'm old enough to remember reading about all of this stuff starting in the early 90s, and bit-by-bit, year-after-year, I've watched it all slowly unravel just the way I had read it would... Its pretty fucking scary stuff to see come true. In fact, I remember the first time I read about clathrates was here on Metafilter many years ago. Can't find the exact article, but I could swear it was at least 5 years ago. Now, we're seeing it happen, almost exactly as predicted.

By the way, I've been thinking for absolutely ages now that humanity needs to start preparing for life underground. With geothermal energy and possibly some other sources we could grow food underground and create a relatively controlled environment and atmosphere. But, the only way to survive is to be prepared. At least the vagaries of weather won't affect us underground. The only thing we'd really have to fear would be earthquakes.

I've heard some actually want to try to mine that methane, since it can be used as a fuel. Fun stuff.
Also, unlike CO2 methane deteriorates over time in the atmosphere, According to Wikipedia the lifetime in the atmosphere is just 9.6 years.
Also keep in mind that we can reverse global warming by dumping particulates into the atmosphere. In fact, researchers have figured out a way to create particles that will hover around the poles, keeping ice from melting. The estimated cost is orders of magnitude less then the proposed wall street bailout, at least according to this TED talk.
But then he started talking about how we'll probably live to see the extinction of the polar bears and I couldn't help thinking how, on top of everything else going on recently, we're pretty much going to hell in a handbasket.
I'm pretty sure polar bears don't actually need ice and glaciers to live. I don't think they'll go extinct.

I will continue to hold out hope that we will be able to survive through this as a species, somehow. The 70% of terrestrial vertebrates that went extinct in the Permian-Triassic extinction event didn't have Science, after all.
The alternative is just to curl up under the bed and start weeping.

delmoi: yes, methane deteriorates in the atmosphere -- but while it's there, it's a much, much more potent greenhouse gas.
Re-quoting wikipedia: despite its atmospheric lifetime of around 12 years, it has a global warming potential of 62 over 20 years and 23 over 100 years.
Ok, enough doom and gloom. I'm going to go plant some flowers, drink a beer, and play with my kids. While there's life, there's hope, right?

did somebody say H2S? mmmmm...hydrogen sulfide. that, in the end is probably gonna be what actually KILLS us all. (think i read about it here...) see, the greenhouse gasses cause the poles to melt, the oceans become depleted of oxygen (most of the O2 in the water is absorbed by colder water near the poles), and anaerobic, H2S-producing bacteria get busy producing mile-wide bubbles of H2S, which turns the oceans purple, the sky orange, and gasses every living thing to death. that is apparently what caused the Permian extinction (AKA the Great Extinction), whose final mineral strata contain whopping craploads of hydrogen sulfide. (the permian extintion is the only event in earth's history where significant numbers of INSECTS perished, btw)
now for the depressing part.
the Permian extinction event isnt the worst in the worlds history. it's the second worst. the worst is happening right now. fortunately, the earth contains more different species now than it ever has, but not. for. long....

Well, if it makes anyone feel better, the global growth rate of methane in the atmosphere [graph] is actually dropping, not going up. Further, there have been no systematic studies of methane in the Arctic, so what these scientists are seeing could be well within the range of "normal". Finally it takes a while for the world to heat up so nothing dramatic is happening. 5MeoCMP's post about liquid methane causing firestorms and destroying life in Earth is I guess possible, but it would take an earth at least 6 degrees C warmer than it is today, and that would take at least a century under the worse case scenarios - and before that happens we will all mostly be dead anyway.

stbalbach, that graph ends in 2005. We are talking here about something that was discovered a few days ago:
posted by splice at 6:21 AM on September 25, 2008
Yesterday, for the first time, we documented a field where the release was so intense that the methane did not have time to dissolve into the seawater but was rising as methane bubbles to the sea surface.I wouldn't expect the graph to reflect these changes.
posted by splice at 6:21 AM on September 25, 2008
It's even more complicated, spice, because emissions come from multiple sources and the recent 10-year slowdown has been a result of human activiity - namely a slowdown in wetland destruction and economic decline after the fall of the USSR.
NOAA or someone much track methane readings on a daily basis, just as they do for CO2. It would help calm some fears to see that methane levels in the atmosphere are not trending straight up, but remaining steady or going down, as has been the case up to 2005.
