   It seems that our human instincts have been wiped out by miss-information coming from big oil and their cabal.

   Designed to dumb down where we are headed now, without any care for our very human instincts of ‘fear and flight’.

   Industry believe in “live in ignorance”

   We used to believe in “she’ll be right”

   Now what is understandable and real is; “we will not be all right”.

   It seems that no change to human awareness will happen till we are all deeply affected by climate change and sadly then it will be beyond our power to change the spiraling worsening of life and weather events that will destroy us and life.

     And if you do panic, ride that wave, recover and harness that energy for your particular response; garden like crazy, network like your life depends on it, support anyone who, like yourself, is fired-up by circumstance!

   Nowhere to run, nowhere to hide: let's hope those cascades don't eventuate and that action now will deflect the harm. With that positive perspective mind, let's get busy, and by that I mean you and me getting busy; we know enough to be getting by on, let's make real our beliefs. Me, I'm planting trees for Africa!

     I agree.

     I want to be writing more proactive, life affirming posts on CC, but I keep getting distracted by the crisis stuff. There's a tension for me between leaving the hard stuff alone or keeping on raising awareness.

     I'm also wondering if people are reaching their tolerance for the bad news.

       to put that more clearly, I'm not sure if my energy is better spent on the proactive or the waking people up stuff. It seems like there is still a lot of complacency about what the situation, eg electric cars will save the day so the focus is on those things.

   The best time to act on these problems was fifty years ago. And the best defense is to increase the size and diversity of local biomass. It's not that hard – plant a tree. Better yet a row of them. Change lawn to pergola, fruiting forest or beefodder and kiss the mower goodbye. Replant the kina barrens. Dig in and make like a therapsid.

     A "row of them" I'm fascinated by what the "kina barrens" might be, but yes, make like the therapsid!
     • Stuart Munro. 5.1.1

       6 December 2019 at 5:42 pm

       Kina barrens are coastal water areas where the removal of key predator species, such as snapper and crayfish, has allowed kina populations to expand rapidly until they browse away all the kelp forest, with consequent loss of biomass, productivity, species diversity and robustness. Not so common down south – the bracing weather 🙂 protects the fisheries to some degree down there.

       If you think terrestrial reafforestation is rapid, wait till you see how fast macrocystis can be re-established, given only a bit of a hand. No systematic replanting of it as yet however – maybe in fifty years.

         7 December 2019 at 3:34 pm

         Thanks for that. If we had the space I'd use a scythe – avoids caring for animals. I use a non-stainless knife sharpened with a scythe sharpening stone. Gave up the push mower when someone said how much they liked the grass unmown. Enjoying the grass and clover flowers and looking forward to self sown grass seed. The knife works well as a hedge trimmer too. You have to be careful not to cut yourself, but paying close attention is good for my state of mind. I kneel to do the work and put the cuttings between plants to shade the soil and as a mulch. The sound of the knife cutting the grass is not quite as lovely as the scythe, but you are closer to it – more intimate with what you are doing.

             Nice one Grafton. I have a dedicated wee patch of grass left and it provides all the straw I require for the chooks, and also some good mulch. I use a large knife too it only requires a couple of cuts a a year. The strips of lawn out front (paths between gardens is all that's left) get electric trimmed, and the whole shebang is a pleasing advertisement to growing your own.

   I'm hunkering down 1650 ft up in the Gisborne ranges on our 10 area farm let.

   Still wringing my wrists attempting to lower my stress levels, because i am feeling a loss of ability to turn the tide of climate change.

   I agree with Stuart Monroe at 5 that 50 yrs ago we should have made changes then.

   I recall it was then in 1963 we were sitting in a pub listening to a wise elder on the west coast saying the atmospheric oxygen levels were diminishing then from around 36% to about 22 percent then.

   We have never forgotten that point but since then, but the press never said anything about it since.

   Now we know it is happening, and that CO2 levels have been rising.

   Then since oxygen atmospheric levels have declined somewhat it appears that the writing was on the wall then, but the media were not prepared to alert us all to the changes coming then.

       A tip for transitioning from city driver to walker – although I'm guessing people are already on to this. You can explore your area with Google satellite maps and be surprised how much public green space there is that you didn't know about, including schools. I use this as a tool to plan routes and coordinate with the train. Not buses because I don't want to feel crowded and have to rely on the driver and traffic conditions. The nice things about trains is they have one track, more space inside, more predictable times and wonderful unmown and unlandscaped sidings and usually stations too – although Newmarket and Panmure in Auckland are totally designed and landscaped – but the contrast strengthens the appeal of others. I also enjoy the sound the train makes as it gathers speed and slows to stop, the amazing spells of no acceleration.

     Just in case anyone gets alarmed about falling oxygen levels, here's a piece that discusses it:

     https://www.inverse.com/article/21419-atmospheric-oxygen-levels-falling

     tl;dr : In the time human activities have pushed CO2 levels from about 280ppm to 410ppm (which is a huge problem), O2 levels have decreased from about 209,560ppm to 209,430ppm – a negligible 0.06%. Indeed, going from sea level to 1650 feet reduces oxygen pressure by around 5%. Changes in atmospheric oxygen are way too tiny to be of even the slightest concern.

     Reductions in ocean oxygen are of significant concern – but that's not related to reductions in atmospheric oxygen. Ocean oxygen reduction is due much more to warming and to all the pollution we're dumping in it (mostly agricultural runoff).

     There are indeed some credible estimates atmospheric oxygen once got as high as 36% (it's about 21% now), but that was 300 million years ago (ie before even the dinosaur era). Other credible estimates have the highest ever oxygen concentration only a little bit higher than now. It's worth noting that higher oxygen concentration really help fires – if somehow there were oxygen concentrations of 35%, forests we have now simply wouldn't exist, they'd have burned a long long time ago.

       Also for context, if you want to experience what the reduction in atmospheric oxygen over the last 800,000 years has meant, go to the 30th floor of any building and open a window. The difference in oxygen content between the ground floor and the 30th floor is the same as the reduction.

   Perhaps someone could say 'I'm going to,,,,this week. And would others like to explore what is happening in their area and we'll all get together with our findings and opinions in the community and put them up on this blog Friday or Saturday. Could we have a doings post that goes up on Friday and gets added to over the weekend. Hearing about what is happening would be heartening and sharing what we have found out and plan is likely to be affirming for us.!?

   One little thing I have started doing is looking for something positive that the Labour Coalition is doing and putting those up under the Latin of (look it up starts with A). I'll come back with that my brain is mush. ACTA NON VERBA perhaps I’ll remember now. Anyone else can join in with something positive that is being done, or planned and likely. (Acta non Verba being deeds not words. I chose latin so it’s easy to call up as a search term. Please don’t start spoiling it any of you who have that inclination.)

   The Sunday How to Get There can still go on where there is thinking, ideas and reports of what is happening overseas.

     It will be good if someone has a constructive comment on this idea of running little projects and reporting on them. Others who prefer to do nothing can leave it be. If no-one replies that will be informative too. In my social policy studies they taught that when no policy was formed about obviously immediate and important matters, that actually constituted as a decision that noted lack of commitment and low priority for action.

   Oxygen Level Decrease in Air from Climate Change

   Oxygen Level Decrease in Air from Climate Change
   Paul Beckwith University of Ottawa.
   Combustion of fossil fuels causes oxygen to decrease in the atmosphere/ocean system.

   As does deforestation, exponential population growth and phytoplankton loss in the oceans from warming stratification limiting nutrients at the surface.

   It is often said that the oxygen in every second breath you take is produced by photo plankton, that are the true lungs of the planet. I discuss the extend of the oxygen decrease, which is more than you want to know.

     Just in case any is alarmed by the above, Paul Beckwith is a doomer in the Guy McPherson mould, trading off his academic credentials in an unrelated field (in Beckwith's case, laser physics) to spread wildly inaccurate alarmist nonsense. Fortunately for anyone trying to work out whether to assign him any credibility (he should be given none), he makes definite specific forecasts for the very short-term which quickly prove to be wildly wrong, such as the Arctic Ocean being completely ice-free by 2013.

       Thank you for these excellent responses Andre.

       Indisputably the fossil carbon corporates spent hundreds of millions creating confusion and doubt. History will judge them very harshly indeed. At the same time there was also a strand of 'doomer environmentalism' that was happy to exploit the crisis as an excuse to 'smash capitalism'. Both were adept at covering their tracks and obscuring their motives, but ultimately I believe both have corrupted the debate and contributed to a deep erosion of trust that has prevented us achieving a political consensus in a timely fashion.

       Because while this was always fundamentally a science and engineering problem, when it was twisted into a polarised political issue, progress ground to a halt for at least three decades. However we now have considerable grounds for optimism, the public mood is shifting toward rejecting both extremes. We now have at hand all the technical and environmental tools needed to solve this crisis; many of which have been discussed here at TS over the years.

       Recently I've had good success in conversations with climate skeptics, or even downright deniers, with this approach. I explain my first hand experience informing me that the science, while never perfect, is compelling. I may not be a climate scientist’s little finger, but I understand enough to know it cannot be a hoax. And while this is a crisis historically created by science, engineering and capitalism … the solutions will be born of the same forces. Most people I find are quite receptive to this argument, one that presupposes an economic system that we know works and delivers astonishing outcomes, but retools it to better purposes. It re-frames the argument into a form that people can trust. Instead of parting in angry bitterness, there is a nodding sense that both sides of the debate have heard each other.

       There is so much work to be done Andre; I only wish I was at the beginning of my career not the end of it, so as I could participate in this revolution. The future lies with you now; I almost envy your opportunities.
       • Andre 8.4.2.1

         7 December 2019 at 2:21 pm

         Sadly, I've yet to find my entry into renewable energy and/or climate change mitigation engineering. At 56, my career is much closer to its end than beginning. I talk about the opportunities a lot with my teenagers, maybe one or more of them will go down that path.

         My specialty is advanced composites engineering, how to design, structurally analyse, and build composite items (so if wind-turbine blades were being built in NZ I'd be doing everything I could to get involved). But I've had occasion to do a few projects where absorption and radiation of solar and thermal infrared were key issues. What I had to learn for those gave me a bit of a handle on those energy balance issues.

         It really bunches my undies when I see opposition to making serious efforts to get to zero-carbon on the grounds of cost and/or reduced economic growth (because it ain't true).

         All the activity needed to get to zero carbon is economic activity, creating lots of growth and winners, with the only losers being fossil fuel interests (that have had it way to good for waaaay too long). Reworking our energy supply and distribution to get to zero-carbon is a project on the scale of rebuilding after WW2, which was a long long spell of sustained high economic growth.

         Even if the cost/reduced growth argument were true (which it fkn isn't), it doesn't account for the way that not making the transition would be extremely costly and growth reducing.

         Finally (and most important to me), it's simply morally wrong to impose extra on top of the already massive burdens of locked-in change we've imposed on future beings on this planet, just for the sake of a few dollars now.

         I too get frustrated with those that use climate change as a stalking horse for other agendas. Other types of government with different socio-economic arrangements have fucked up their environments and spewed hazardous wastes into the atmosphere just as enthusiastically as western liberal-democratic mixed economies.

         The socio-political arrangements we choose for ourselves are a separate issue to to change our energy use habits away from shitting our collective bed. They are separate topics with separate arguments on the merits for each. Conflating them only serves to muddy them both, which serves nobody except the few skimming the massive benefits at the top that seek to keep their current gravy train going as long as possible.

           Just out of curiosity Andre, can wind turbine blades not be made of carbon fibre epoxy composites.

           I would have thought with NZ's expertise in high performance Americas Cup boats and now Rocket Lab carbon fibre tech we would be well placed to create such industries.

           When you look at a wind turbine they seem like pretty rudimentary technology to me. The first thing I would do is add funnels that optimise the wind speed past the blades to maximise electricity generated in low or high wind speeds.

           Is it just funding that is preventing this? What about https://www.callaghaninnovation.govt.nz. Would they not fund a start up?

             7 December 2019 at 7:33 pm

             Yes, turbine blades are indeed made of of epoxy composites using methods similar to those used in some marine industry and possibly for some Rocket Lab parts*. Certainly there are plenty of people in those places with the skills needed to make blades in low volumes, if not in massively high production volumes.

             But for cost reasons the vast majority of the fibre reinforcement is glass fibre, not carbon fibre. The main use of carbon fibre is in unidirectional spar caps on the top and bottom of the shear web running up the middle of the blade.

             It's a volume of production thing why we don't build the blades here. Factories in Europe and Asia are turning them out at incredible speeds, I vaguely recall reading an article about producing a blade a day out of each mouldset. Developing the capacity to do them that quickly takes an enormous amount of R&D and capital equipment, but the reward is a much lower per-unit cost when you build a lot of them.

             There have been attempts to develop wind turbines here. Windflow developed a two-bladed turbine with a very innovative gearbox and actually produced a few turbines. But through a combination of managerial and money issues, and the extremely rapid technology development overseas basically passing them by, they dropped out.

             Vortec were working on what was effectively a ducted turbine design, but they never even got as far as a full scale working prototype.

             IIRC, both companies got quite a bit of government R&D funding, but neither could really get a foothold against the incredibly rapid pace of development from overseas suppliers.

             *Technically speaking, turbine blades are generally made by infusing liquid resin into a dry fibre reinforcement stack, while the highest performing parts made by Rocket Lab and America’s cup etc will use prepreg, where the fibre and resin come from a factory in unidirectional rolls with the resin in a partially cured sticky solid state and a very precisely controlled resin/fibre ratio.

             No. I've had very little involvement in that side of the marine industry for ten years.

             From an engineering perspective, yeah those foils are really interesting (along with a bunch of other stuff that doesn't get publicity). But I spent seven years doing America's Cup and Volvo and TP52 etc, and in the end it got to me putting my everything into making toys for big boys with way too much money and mine's bigger than yours issues. I much prefer working on projects that deliver real products that real ordinary people can go out and have fun or do useful stuff with, not the fantasyland way off in the megamoney clouds stuff.

               After 20 years building public transport infrastructure, I'm doing a bit of the big boys' toys thing for AC36, before I head off the next mega-project. Not much socialist justification for it, but a whole bunch of fun nevertheless.

                 According to this report the movement for free public transport is being spearheaded by the young.

                 Public transit has become a focus on intense political activity in cities across the country as young climate change protestors demand investment in mass transit to help battle climate change.

                   I reckon cost is only a part of the choice in what transport mode to use, and once you're above a fairly minimal income level cost is a very small factor in the choice.

                   Travel time, comfort, convenience, perceived safety, perceived control are much bigger factors than cost for all but the lowest income sectors.

                   For my kids, they're quite happy taking the bus and train where they want to go, and since the Hop fairy keeps their cards topped up, it's free to them. Nevertheless they're very keen to get their driver licenses for the freedom and time savings, even though they know they will start paying for their travel at that point.

                   It's for things like trips into downtown Dorkland that they still prefer public transport, to avoid the hassle of parking and gridlock. But to them, those are big reasons to just not go downtown unless absolutely necessary.

                   Big picture, I reckon free public transport is probably worth a try to see if it lifts ridership enough to make it worthwhile increasing services to improve speed and convenience which then further lifts ridership. But I wouldn't be surprised if it falls a long way short of that and would only do a little bit to get people out of cars.

                   The success of the Northern Busway is because it's a lot faster and more reliable than sitting on the motorway, not so much because it's cheaper (I suspect it probably isn't cheaper for a lot of the users). But the opportunities to spread that model to other parts of the city aren't great.

                     Hi Andre.
                     Talking about the success of the Northern Busway. It has long been my contention that the busway needs to be continued over the Auckland Harbour Bridge.
                     This of course would mean taking two car lanes off the carriageway .
                     (meaning less cars in the CBD not a bad thing in my opinion)

                     I was thinking of using the two Eastern lanes. Going South exiting onto Fanshaw Street. Going North from Fanshaw Street to Curran Street looping around Pt Erin to enter the north bound bus lane across the Shelley Beach Road flyover. North bound buses could also enter the Shelley Beach flyover from Jervois Road.

                     This would mean changing the direction of travel on the Shelley Beach flyover from south to north. Cars can exit/enter the Westhaven Marina through Curran Street, or Fanshaw. (not a big hardship for the relatively small marina traffic.)

                     The cost for making these changes would be minimal compared to the $6 to $10 billion harbour tunnel proposed by the Key Government. Which would only deliver more cars (and pollution), into the CBD.

                     And yes this cross harbour busway should be fare free. For two reasons, one to compensate commuters for leaving their cars at home. And two for the convenience, a factor that you have already mentioned as a positive. Hop on and off at your leisure, no coins to find, no hop cards to lose or forget to top up.

                     Speedily crossing the Harbour Bridge in comfort stress free, able to admire the views towards Rangitoto properly for the very first time with out having to keep a fixed forward gaze and your hands in a death grip on a steering wheel.

                     I think cost is a factor for families because one car ride is a lot cheaper in most instances than 3-4 bus/train fares, so owning a car is cheaper (and certainly a lot more convenient for younger children).

                     Cost obviously isn't a major factor for individuals, because if it was, more people in Chch would use the bus as their principal mode of transport with the occasional taxi or equivalent, rather than bothering with a car.

     Sigh 🙁 For the umpteenth time, this is how you (could) do it:

     Oxygen Level Decrease in Air from Climate Change by Paul Beckwith, University of Ottawa:

     Combustion of fossil fuels causes oxygen to decrease in the atmosphere/ocean system.

     As does deforestation, exponential population growth and phytoplankton loss in the oceans from warming stratification limiting nutrients at the surface.

     It is often said that the oxygen in every second breath you take is produced by photo plankton, that are the true lungs of the planet. I discuss the extend of the oxygen decrease, which is more than you want to know.

   Thinking of climate on a more immediate and local level – the West Coast has numbers of slips between Hokitika and Haast and places are cut off. Electricity is off for a while and I think Fox Glacier is affected. Lake Wanaka is rising steadily and parts of the town are under water.

   We may have to think about supporting such areas economies while they try to continue living with conditions that are becoming more trying. Perhaps some of us need to become 'disaster tourists' who will be invited to stay when there is sufficient recovery, and be prepared to brighten their lives with whatever music we can perform, and bring scones, butter

   It would be a great time with people who wished the visitors to come and welcomed the help, goodwill and revenue. And better than other samey holidays visiting some place where you pay good money then compare it unfavourably to last year's.

       That is not a reply that indicates green practicality. We have people who need an economy as we all do. It would also be good to show solidarity amongst NZs. While we keep our eyes open to the climate change matters, we cannot drop people off the end of the pier and say if you can't swim, then you're out of luck. What we need from thinking Greens is a reasoned transition down from our present practices not a few snappy words that are a general slogan applied to a situation of local need.

         7 December 2019 at 1:13 pm

         sure. And most of the green movement has been saying exactly this for quite some time now.

         However in the context of this post, which is a serious warning that we don't have time to waste, I can't see the political validity in promoting more tourism to solve adaptation issues. The push needs to be to get NZ off its reliance on mass tourism as well as our drive where and when you want attitude.

         Tourism as an industry is lagging worse than farming when it comes to climate transition, and are still largely in denial. When they can bring themselves to talk about it at all it seems to be around electrifying their industry. But as you are pointing to, that won't work in many of our high tourism areas with increased extreme weather events. And that's not even getting to what will happen to those communities and economies when the Alpine Fault shifts.

         I've been around the jobs vs environment argument since the 90s. Just transition really can't be about putting off emissions reduction because we're too mired in old thinking about how economies must work. This is pretty much the line farmes are running and it will kill us.

         I actually agree that one of the needed solutions here is for NZers to holiday closer to home, but that won't resolve the problems of small communities being so reliant on tourism to make a living. The sooner we all transition off that the better. The biggest block to that at the moment is people thinking green tech will save us, and that the middle classes don't want to sacrifice their lifestyles (in this case holidaying at will, but also those that own or work in tourism businesses that support their overshoot lifestyles).

             Experience it remotely ? I can imagine Hokitika hiring out a fleet of drones to remote tourists who want to explore the area without travelling there. The drones programmed to minimise intrusion. Like Youtube videos of exotic places – imagining adds to the pleasure. The service would be available at set times, a season to remotely explore Hokitika with your hire drone.

        I guess the problem I have with the nature paper is that it doesn’t allow for the possibility a time of plenty associated with more carbon and higher temperatures. Whether or not humans are there to enjoy it is largely irrelevant.

        Which brings me on to XR, the lower upper middle wokies, who have an amazingly blind human centric view of the environment. Their outcomes only focus on the inability of humans to survive, ignoring that the planet will always be here, regardless of our presence or activities.

          7 December 2019 at 1:03 pm

          One of the central tenets of XR is the importance of nature beyond human needs. Hence they core demand is around telling the truth about climate change and the ecological crisis. Not sure who you have been following from XR, but the people I am reading are deeply engaged with the impacts on nature and the rights of nature.

          "Whether or not humans are there to enjoy it is largely irrelevant."

          I disagree. Humans are part of nature too. But even if you don't care about the suffering of this particular life form, there are compelling, nature-centric reasons for humans to do the right thing irrespective of whether we go extinct or not.

          As for allowing for "the possibility a time of plenty associated with more carbon and higher temperatures", I'm going to guess the problem isn't so much that Nature didn't address that (why should they, the piece was about the problems of climate science underplaying tipping points), but that you have a kind of denialist approach that you're not being particularly up front about. You may know that I don't allow denialist lines under my posts. Despite having started this conversation by trolling, I guess there's an opportunity here for you to say what you really mean but you still need to abide by the rules.

          Foolish; "ignoring that the planet will always be here, regardless of our presence or activities." – what me worry said the guy on MAD cover.

          Is that a message from the Great Creator Climaction? The planet may go on despite all but we will kill off most of ourselves and most other living things of our time. Mars is still there, but it's environment and atmosphere are negative to life as we know it. Why not try to save the magical life that is here and not just treat it as a passing artifact although we ourselves, are the passing artifacts?*

          * Artifact – an object made by a human being, typically one of cultural or historical interest.

          (I was made through the combined work of two humans, with the living spark which comes from a distant Creator, and the rest of the definition is, I believe, true.)

    After our petulance (at the ongoing fires) comes a stoic, patient reasoning. It’s good for us to get this wake-up call. And it’ll be over soon. But that was weeks ago, and the patience has been replaced by a grim, creeping dread. A fear that it won’t be over soon, or ever. It feels like karma. This is what the scientists have warned us about, begged us to think of, all these years. It’s here. And it’s going to get worse.

    "Low oxygen levels are also associated with global heating, because the warmer water holds less oxygen and the heating causes stratification, so there is less of the vital mixing of oxygen-rich and oxygen-poor layers. Oceans are expected to lose about 3-4% of their oxygen by the end of this century, but the impact will be much greater in the levels closest to the surface, where many species are concentrated, and in the mid to high latitudes."

      I often think about this too – what makes people buy and use all this and travel to remote places with no aim but the novelty. It must be to feel powerful and as Andre says above wrt transport choices "comfort, convenience, perceived safety, perceived control". The reassurance that comes from control is what I crave, and I think others too. Our perceived freedom has made us deeply fearful.
