I can agree with that assessment... they're typically fairly trashy. I've submitted content from them before when it was an AP article (so the text was identical on all sites that carried it) but they had additional relevant, higher resolution images accompanying the text. Got unnecessary flak for it of course.
What makes you say that? Like much of the Daily Mail, it seems to be sensationalised in a way that makes understanding the (probably important) content rather difficult. The headline is incredibly misleading, to start with.
I guess it's not safe (probably explosive) and even if it was safe how could that be done when it springs up from random holes dispersed in a vast area (Siberia)?
Methane burns to produce carbon dioxide and water. Carbon dioxide is a greenhouse gas.
But to burn it you'd have to collect the methane and concentrate it first, otherwise at low concentrations it is unlikely to ignite. Given that the Siberian arctic is vast and remote, I don't think this is a practical proposition.
It does, but according to the Wikipedia article the '25 times' figure seems to have taken that into account. Methane has a 25 times (or 34 times according to more recent estimates) larger effect than an equivalent mass of CO2 over 100 years. When measured over the first 20 years this rises to 70~80 times.
And where does this calculation come from? How was it determined that this is
a valid approximation of a physical process? This "global warming potential"
seems to assume that a wave of certain length can be reflected and absorbed at
the same time, which idea is somewhat unexpected if you dig through optics
handbooks.
What gave you that idea? Radiative transfer is physics. That doesn't change because we're talking about planet earth. I would guess that most scientists involved in climatology have a physics background.
It's a shame that the whole matter of global warming has been politicized and muddied so much by special interests that average person simply doesn't care anymore. That's why it's especially weird to see something like this published in Daily Mail. The positive feedback loop is definitely happening though, but the magnitude and extents of it could still vary.
To be honest, I don't believe we can stop this, not with the current population size and the current economic model.

The Daily Mail profits from sensationalism, it's not really like Fox News in the sense that it only pushes one ideological position. So you'll get it reporting sensationalist articles for and against action on climate change (although historically it has been mostly anti, because it makes a better story for the purposes of invoking outrage).
This article is sensationalist by overplaying what is happening - the 200 figure actually refers to the concentration of methane in the leaks relative to the atmosphere (it doesn't refer to the actual scale of the leaks in any sense).
As an aside, I'm not sure these sensationalist stories about extreme climate change actually help, they're still basically pandering to readers by offering a way to be outraged without having to do anything. The narrative shifts directly from 'this is not a problem, we don't need to do anything' to 'this is the apocalypse, someone should have done something about it, but now it's too late for me to make any difference'. Then perhaps a few years later, when the apocalypse hasn't happened, it can go back to 'we're still okay, the problem was overblown, we don't need to do anything'. And the boring work of actually working out a solution falls by the wayside.
The best thing for Earth and possibly the thing for homo sapiens is a nuclear winter. Hillary will just continue the drone war and statist business as usual. Trump on the other hand, total wild-card, and possibly unwitting instigator of nuclear war. The long term ecological choice is Trump.
Is it a little presumptuous for you to decide, individually and on humanity's behalf, that widespread death and destruction is the best thing for everyone?
oh. it's going to get a whole lot worse. you can count on it.
I think it's pretty much 100% that we will see geoengineering attempts within our lifetimes, maybe even within the next 20 years. Probably dust injected into the atmosphere.
Aside from the shock value of this, this underlines that there are feedback systems that we have kicked in. I think the science is not clear, we are still learning about the effects. Climate sceptics are right in a perverse way, we have no idea really what we have done.
James Lovelock (the inventor of the Gaia hypothesis and the discoverer of CFC's in the atmosphere) seems to think only the northern parts of the planet will remain habitable, sustaining a population of a few hundred million - we'll see.
If this is true, Should I move my family to Northern Europe (Sweden, Finland, Norway, Iceland) for the sake of my descendants? I've been thinking about this for a long time.
It's too late to stop the feedback loop. I fear the current migration crisis is nothing compared to what will come.
Many parts of that area are still rebounding from the mass of the ice sheets and are rising faster than sea level. For those of us in the USA, the Great Lakes region would likely be the best bet.
I haven't researched climate change effects; but my guess is subsistence farmers will be affected a lot. Even if climate change had equal effects to all income groups, that would affect poor people more (for a poor person losing 1$ has more effect compare to a billionare).
Farms would not stop sending food. People (HN readers are at least in the top income half (1) globally) would pay more money to buy food. Food is an essential commodity and I don't think an apocalypse is going to occur due to climate change.
tl;dr food is going to cost more and HN readers can afford that while poor people might not be able to afford it
Food will cost more overall, since global arable land will reduce. But in some northern areas the growing season could actually lengthen.
I hope that the timescales are such that drastic effects won't happen this century and give humans more time to adjust/come up with technology to mitigate the effects.
2c warming by end of the century would be terrible, 10c disastrous
"Me first" stuff like this won't get you real far IMO.
I went as far as Tromsø, Norway late last year and was shocked that most of their produce comes from the kind of place you might try flee from. Most of the fruit and vegetables I purchased had been shipped from places like Spain and South America. Basically if it becomes so bad these countries start to starve it won't be a priority to send food to the Arctic leaving people in the North vulnerable and, there are a lot of people up there already. You're not just going to move to some little village in Sweden and escape this pending disaster.
These large Northern populations heavily rely on produce and clothing coming from down South.
I did stay with people in Sweden who are kind of self sufficient, but if one looked closely, it was easy to see they still need solar panels, medicine, hunting equipment, cars, fertilizer etc, this is not stuff produced locally.
Best thing one can do for the next generation is change our ways immediately, consume less meat and fish, divest from fossil fuels, demand action from our politicians and stop having so many kids. It's pretty clear a population of 9 billion is going not going to work with current technology and attitudes.
It's easy to see isn't a problem anyone of us can run from, we're all going to have to pay the toll for what some call "endless growth".
If you look at a plot of human population in the last century, it's similar to log-phase bacterial growth. We've had uncontrolled proliferation based on non-renewable resources - especially the capacity of the biosphere to deal with waste CO2 - and we're about to run out. A lot of dieback is reasonable to assume.
No no, I'm Icelandic. It's nice right now but that's thanks to the gulf stream. Global warming is slowing it down and it could end up diverting it, making temperatures plummet to Greenland levels.
What feedback system would that be? Wouldn't methane accelerate warming? From my limited knowledge of English semantics feedback - like in feedback loop - would mean some controlling function?
I'm fairly sure that harwoodleon is referring to positive feedback.
Negative feedback acts to oppose a change (think heating system temperature control). Positive feedback acts to amplify a change, and can result in runaway changes [1].
I remember the intro to earth geology class I took 15 years ago at my university, taught by a climate scientist; the professor would take off a week every time there was a shuttle launch because he'd fly down to Florida and be part of the panel of scientists who would give the astronauts lists of things they were interested having photographed from space. I remember him talking about runaway feedback loops. He would explain them and would explain some historical examples of them we can see in geological data. He seemed really concerned about them, not so much because he thought it probable that the ones we know about are going to run away and make the climate uninhabitable for humans, but rather because he thought that there were lots of feedback loops out there hiding in plain sight that we wouldn't learn about until we started observing them actively happening. He basically seemed to think there was no real way to know with any certainty the upper bounds of how bad we can screw up the climate but that we were effectively running a giant experiment with the entire atmosphere and would within a few generations find out, and he thought that was a pretty big deal.
Just further clarification of how little we understand the damage we're doing at an ever increasing rate.
We've achieved a little awareness along with some limited recycling and energy saving, but still use an order of magnitude more than even as recently as the 80s. Oil companies see melting ice caps and think "great! new places to exploit"
I don't see much hope of change until something seriously dramatic happens. Dramatic enough to convince the most dogmatic politician currently thinkng growth is the only thing that matters.
Only then we'll try and fix it. Probably by having to adopt something like a war economy, globally, with all the restrictions and ramifications that would bring.
The headline is incredibly misleading and looks like a misinterpretation by the Daily Mail (not known for their quality journalism in the first place).
The "200" figure refers to the concentration of methane in the released gas compared to the atmosphere, not the total amount released in the Arctic compared to usual.
Poor article.
EDIT: This HN post originally linked to a Daily Mail article with a bad headline. The Siberian Times headline is still misleading but not quite so egregiously wrong.
They always have really good pictures though, if someone made a plugin that overlaid the article with a good one while keeping the pictures it would be great.
Its seriously bad, and we still argue about electric cars and profitability of solar power:
Methane is powerful enough to create rapid warming feedback loop that cannot be stopped by current means(unless the world economies are changed overnight), there is a model that shows +6C warming effects if methane reaches 1000ppm(2000 Gt release):
http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-11-00533....
Notice the predictions of methane release from 2013 are on track:
https://www.theguardian.com/environment/earth-insight/2013/a...
It's everywhere, dead leafs under the tree that used to be frozen now are being composted by bacteria producing methane, you would have to cover ground with plastic foil.
>> dead leafs under the tree that used to be frozen now are being composted by bacteria producing methane
This is THE thing people overlook. There used to be trees there! There used to be lots of vegetation, that's why there's so much carbon trapped in the permafrost in the first place. We're not releasing something bad, we're returning the earth to a better equilibrium. Imagine if the Siberian tundra were replaced with forests and farms. Imagine if we avoid the next glaciation - which is coming if we do as the climate alarmists want, yet there is evidence that we can't prevent it even if we try.
Imagine if the Siberian tundra were replaced with forests and farms, and current forests and farms were replaced with desert.
You can't just look at the potential upside, assume it will be huge, and also assume there aren't any negative effects that might outweigh it.
The argument that the Earth used to be warmer or cooler or whatever is completely nonsensical. We're not worried about Earth, we're worried about people, and more specifically civilization. The fact that the tundra used to be lush doesn't mean anything in that respect.
Yeah, and "just" relocating ain't exactly trivial or foolproof.
The alternative is glaciation? If we have enough control over the climate to make it a bunch warmer, surely we have enough control (should we choose to exercise it) to keep it in the middle.
Elsewhere in the arctic: Geophysical Letters 22 JUN 2016: onlinelibrary.wiley.com/doi/10.1002/2016GL069292/pdf reports "No significant increase in long-term CH4 emissions on North Slope of Alaska despite significant increase in air temperature"
Yale Climate Connections on the melting permafrost in 2013: https://www.youtube.com/watch?v=FLCgybStZ4g - sad to see we have been moving so slowly in the three years since I watched it.
Serious question: Is there any research in how far will nature be able to adapt? For example, if the permafrost melts, wouldn't that enable growth of CO2 absorbing plants in those areas?
We don't know what runaway climate change will look like. The system is chaotic with lots of feedback loops. Stuff will happen, some of it counter-intuitive. It may or may not be okay in the end.
I like Elon's take: yeah, it might not be that bad, but is it really smart to do an uncontrolled experiment on your own biosphere and "see what happens?"
I also like George Carlin's: "Stop talking about saving the Earth! The Earth is four billion years old. The Earth will be fine. We're fucked."
Carlin's comment is actually quite wise. Life will adapt, but adaptation is a painful evolutionary process that often involves a lot of death. Concern over things like climate change is entirely self-interested. We don't want to unleash a Darwinian "adaptive" process at the global scale upon ourselves.
I didn't read the article closely enough, but I'd be interested to see if this methane is released from a stored source or if it is from rotting vegetation.
Much of the permafrost area is a frozen swamp; when it thaws, the swamp plants rot.
In other words, this may be a one-time outgassing of a limited amount of vegetable material, at least in this case. We still have the clathrate gun to worry about.

You're probably right though, it's probably not too diffuse and generally impractical.
True, although it decays to CO2 and water after about twelve years [1].
[1] https://en.wikipedia.org/wiki/Global_warming_potential#Value...
Where does this number come from? Heat capacity is almost the same for CH4 and CO2 (and half of that of H2O).
Not to mention that the formulas are incomplete.
This is the part I'm not so sure about. Physicists tend to not bother with climatology.
Edit: for example, Radiative Forcing in the AR5 http://climate.envsci.rutgers.edu/climdyn2013/IPCC/IPCC_WGI1...
