Looks like there was such a cliff around this time in 2010.
Well done, Paul. I couldn't put it down. What occurred to me as I read it was how many alternate versions there could be – how impossible it is to predict and prepare. Like Neven I think (hope?) the timing is a bit early, but the roll-out is one set of very probable scenarios. The story paints a dark picture of how much business still influences the responses. Scary stuff.

Mauri, something got lost in that post – the glacier name, the link. Thanks for being here! Thanks to Yuha's post about the Nature paper I found the Nasa site on the Ice Sheet System Model, of which the paper's lead author is webmaster. http://issm.jpl.nasa.gov/
Thanks, Yuha, for those images. Looking at them I wondered... well I kind of thought exactly what the paper's abstract says: "We detect widespread ice-covered valleys that extend significantly deeper below sea level and farther inland than previously thought. Our findings imply that the outlet glaciers of Greenland, and the ice sheet as a whole, are probably more vulnerable to ocean thermal forcing and peripheral thinning than inferred previously from existing numerical ice-sheet models."
I've sent my donation. Last time they mailed me a nice sticker, etc.

JD Allen I'm with you. Building community (not that gardening isn't a great topic upon which to base friendships). Mister #1 Stop For Storable Food And Supplies is profiting on fear, very much part of the current system, so we needn't try to change his mind. I considered putting canisters of freeze-dried food under the bed during the aftermath of the 1974 oil crisis and decided if something that big happens, we're all in it together.

Neven, I'm so pleased that the donations added up to a significant amount – unusual for bloggers. Your house looks fantastic. Stupid question: could you not put a plastic tank inside the concrete one? My mate had a concrete rainwater cistern at his log house near Algonquin Park and left the lid off for a few minutes. He found out much later, the hard way, that a fairly large, by then unidentifiable, mammal had drowned in there.

Thanks for this dependable update, Neven. When I look at the volume graph I see the post-2009 pattern – ice loss beginning earlier (June instead of September). It's not hard to envision a new set of years where the speed of loss in June looks more like the pre-2010 loss in September-October. It seems likely that one early melt would set that pattern off. And I wonder if the methane situation couldn't precipitate that quite soon.

@ Kevin. Tenney Naumer is the mistress of great links. She's been posting her lists of them every month for years. http://climatechangepsychology.blogspot.ca/
Neven, you spoiled lazies like me with those videos, but I know how a heat wave makes sitting next to a hot computer suck. This uptick – might it not just be the back of a bump? There are a bunch of bumps in the CT 2005=2013 chart. Look at each bump and think how confused we felt before it turned downward. Anyway, that's my purely artistic, non-scientific explanation of the standstill. Think of the car at the top of a roller coaster hill.
It's likely that the arctic melting and weird weather will reach a critical mass in the eyes of the media and Neven's blog will suddenly be a major source of background info for people who drag their heads out of the sand. For that reason I can imagine zippy videos would be handy to have on hand.
Neven, your video is just great. All your hard work allows me to use minimal brainpower to get the gist of this hot spot stuck over the thin ice, poised to pound it. I wouldn't worry about music. The little editing I've done on my Mac in iMovie showed me it's not very difficult to create another track in the timeline and drag some stock music into it. But not an important thing to do with your precious time.
Wow, wonderful sleuthing, Neven. I agree with the few people who have said in response to your post that only positive feedbacks seem likely.
Toggle Commented Jun 20, 2013 on On persistent cyclones at Arctic Sea Ice
Thanks, A-Team for posting that paper. I have such a sketchy understanding of all this, but intuitively (or maybe it's my visual mind) the ideas that the arctic is the end of the line for energy movements and that the swirl of a cyclone sort of hooks itself to the polar vortex make sense to me. It seems like the discussions here about the recent arctic cyclones have been musings about whether they're unusual. At a glance having scanned this over-my-head paper and read the intro and conclusion the concern seems to be that although it's normal for arctic cyclones to persist, the environment in with the 'Atlantification' of the Arctic and Eurasian rivers dumping warm water in, etc. they're persisting in a whole new arctic, which means the effects on the ASI are unpredictable to say the least.
Neven, that video is just my speed! Thanks so much for taking the trouble. I love how you guide us through with your mouse. And it's nice to put a voice to the name and hear that cute accent in combination with your exquisitely idiomatic English.
I'm surrounded by well-informed people relatively newly-arrived in a rural community. They all agree that climate change is messing hugely with the weather, but most will also rail against any rise in fossil fuel prices, so they're not ware how dire things are or that a serious global carbon tax is in order. I suspect Lars Von Trier was feeling like us when he conceived his film Melancholia. The idea is that a stray planet is heading straight for earth and people go on squabbling about the usual little stuff. One character has been watching with his telescope the way we watch the Arctic sea ice, but nobody pays him any attention. I won't give away the ending, but I can see one thing that might feed this filmmaker's chronic depression.

Thanks, SATire. "To try to answer your question despite that: Maybe the paper explains, why a weaker jet stream does not help against blocking events anymore." My (mis?)understanding has been that a weaker jet stream – not spinning fast around the cold polar cap, powered by the difference between temperature/pressure in high and mid latitudes, but wobbling and wowing slowly between areas of lower contrast – is like a rubber band that's lost its elasticity and goes all floppy. So sometimes it gets stuck, not strong enough to push a system around the globe.

Alex, or anyone else who can explain, I think I've been understanding Jennifer Francis on the warming arctic causing the slowing of the jet stream and the staying still of trapped areas of high or low pressure, causing weather extremes to persist longer than they used to. This PNAS paper on quasiresonant amplification – how should that change the way I think about this phenomenon? I cannot do the math.

I'm only a pessimistic Canadian, but this report Joe Romm has just blogged about is from a body whose mandate is pretty lukewarm: "The NCA will help evaluate the effectiveness of our mitigation and adaptation activities and identify economic opportunities that arise as the climate changes. It will also serve to integrate scientific information from multiple sources and highlight key findings and significant gaps in our knowledge. The NCA aims to help the federal government prioritize climate science investments, and in doing so will help to provide the science that can be used by communities around the country to plan more sustainably for our future." I find this phrase particularly ominous:"identify economic opportunities that arise as the climate changes". http://globalchange.gov/what-we-do/assessment/nca-overview
Thanks, Steve, for pointing out the article on CARVE. My concerns are confirmed where the author notes that any results on methane release from permafrost won't make it into the 2013 IPCC projections, so things will look significantly less dire than they in fact are to policy makers. I should say policy foot-draggers.
Thanks, Andrei for the link to Kevin Anderson's revelations. The troubling aspect of discussing adaptation and mitigation is that what's happening is worse than BAU, it's disaster capitalism as laid out by Naomi Klein in The Shock Doctrine. All these extreme weather events aren't problems for business – they're 'opportunities'. Kevin Anderson settles on a controlled economic contraction, putting the onus on individuals in the West to stop consuming energy-intensive crap. Sorry, but that's not going to happen. We've just spent the price of a good used car to retrofit our 900 sq ft house so we can cleanly burn small sticks of local sugar bush thinnings and stop using the oil furnace. A/C? That would be the space blanket blinds we use in summer when the sun hits the windows. Most people think we're hair-shirt hippies. What to do, what to do...
I'm not as versed in ASI as most of you, but I have been watching for news from Semiletov & Shakova for years. Natasha looks so worried in this video. The 200 sites they talk about are the 200 sites they managed to visit this summer in millions of sq km. My concern is that there's no way to make this methane coming up from the oceans part of the models that predict global temperature increase. They're only this year getting the solid sense of how much methane is being released. Am I wrong?
Thanks, Neven for being on top of this so fast, in fact as fast as I could click on the link left here by idunno! I came back to ASI to search Judith Curry and here was this smart post.

I wish there were more news stories out there quoting Jennifer Francis. '“It's exactly the kind of thing I was talking about,” Francis said. “I can't say for sure this particular pattern was influenced by the ice loss, but it is certainly the kind of thing we were expecting to see more of.' Very nice graphic on page 1 explaining the blocking of Sandy's track to ordinary folks like me. http://www.heraldtribune.com/article/20121026/ARTICLE/121029673?p=3&tc=pg
