Permafrost ‘bubbles’ are leaking methane 200 times above the norm

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.
It's too late to stop the feedback loop. I fear the current migration crisis is nothing compared to what will come.
(1) it might be very bad for say a poor farmer, but the typical HN reader will be able to survive it.
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
(1) I think it's more like top 10%.
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
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".
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].

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.
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.
I found this article that says the predicted CO2 levels will increase plant growth: http://www.nature.com/scitable/knowledge/library/effects-of-...
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 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.
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.
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].

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.

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.
Very ominous.
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.
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.
And remember, the alternative is still glaciation.
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.
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.
Daily Mail could be one of the top list of websites that can be banned from HN.
A lot of times they also use screen shots from a video (for example - Youtube) and write a text commentary to generate an article.
(the Daily Mail? Seriously?)

Reporting quality seems to be good with a lot of images. If the message is good, why criticize the messenger?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.
Yet the story is a good one.
