Project Drawdown

9 02 2018

I’m writing this, because Sustainable Living Tasmania has invited Paul Hawken, author/editor of his latest book by the same title as this blog entry, to speak in Hobart….. and I won’t be going, because all I’d end up doing is yelling and screaming at him!!

Hawken’s book lists 100 ways to ‘effectively combat climate change’. I vehemently disagree with most of this list, because in my opinion the solutions are not technical as Hawken suggest, but social. I’m really sticking my neck out challenging someone as prominent as Hawken, whose techno Utopia has obviously been universally embraced going by a quick google of the subject matter….  but at the very least, an alternative form of discussion needs to be attempted.

collage-drawdownThe book’s number one entry is refrigeration. Hawken claims, and probably quite rightly, that changing refrigerants and effectively destroying those gases at end of life could avoid emissions equivalent to 89.7 gigatons of carbon dioxide. But there’s no mention of making better insulated fridges, or fridges that last 30 to 40 years, like they used to….. nor that the current craze for enormous fridges should end. As an aside, while we were all thinking the ozone layer problem was fixed, along come the news it’s getting worse……. and scientists apparently don’t know why.  Except that some scientists might have a grip on the problem, and yes, it’s good old industrial agriculture at it again.

Number two on the list is wind turbines. Give me a break……  we need to use way less energy, not more. As I’ve stated many times on this blog, every time a turbine is built and erected, more CO2 is emitted, that said turbine will never remove in its lifetime. It’s just more consumption, period. Solar farms only makes the list at number 8.

Number three is reducing food waste. Now I’m all for that, but one of the ironies of refrigeration is that it may cause more food waste than most people realise. Even I have to confess to losing fresh produce in the back of the fridge to only be retrieved for composting purposes…… in my experience, the best way to not waste food is to grow it yourself and fit into a system where there is no waste thanks to chickens and composting. But of course the world won’t change to this until it’s all too late…

Number four is my latest pet hate…….  plant rich diet. Now there’s no denying that too much meat is consumed, but that is only because we have access to refrigeration and fossil fuels to distribute meat to abattoirs and supermarkets. For anyone to even consider we could all become vegetarian, let alone vegan, is a preposterous notion. I have made a big deal lately of the quality of our soils and what they are actually capable of producing; and a global vegetarian diet in a post fossil fuel era, which is after all what we have to strive for if we have any chance of fending off the worst case climate scenarios, is simply Utopian nonsense……  what we have to actually do is dismantle the industrial agricultural system, for both meat and fruit and vegetable production, and turn to permaculture principles.

To his credit, Hawken does in his book mention regenerative agriculture, but it’s ranked 11th, whereas I think it should be at the very top of the list…… he also separates out ‘silvopasture’, not a term I’m familiar with, but which is more or less regenerative farming and permculture. That’s ranked at 9 and should be incorporated with 11 above at the top of the list.

Deforestation at number 5 is a no brainer

The list of 100 is way too long for me to go right through and critique individually, it is literally another book in the making, and maybe someone will have a crack at it one day. I’m certainly too busy implementing my own strategies, and, worse, preparing for the future in which basically none of the things he proposes will happen because we are fast running out of time.

Hawken is a capitalist, and as such will never mention the fact we have to rid ourselves of this crazy system and the monetary setup it is supporting at any cost to preserve the wealth of the 1 to 5%…..

Fortunately, some of the very last items on the list like battery storage and grid flexibility are right where they deserve to be……. Biochar at 72 deserves way better ranking. And while I think green roofs are really cool, I have decided they are of little use wherever water harvesting from roofs will be needed. I find that the simple mention of airplanes (ranked 43) is baffling beyond words. Flying has zero future, in reality (peak oil) and in any climate strategy, period. It only proves to me, Hawken, like most people in his position, simply don’t want to give up their toys. Like electric cars at 26…. or simply cars at 49 about which the list says….:

I can’t help wondering whether that includes manufacturing emissions, mining of Lithium and Cobalt (until they run out, and soon…) or whether Hawken has considered that removing $1.76 trillion from the economy would do to it! The list even claims that the Chevy Volt does an astonishing 150MPG (sorry, but this is an American article, and Americans still haven’t joined the rest of the world and use SI units…) I googled this and could find zero mention of fuel consumption remotely close to this, because while running on petrol/gasoline, it only does 38MPG, and its non fossil fuel range is only 38 miles/70km. It’s also a measure of mass thinking that the main criticism of the car in articles I read was that it only had four seats!  But I digress…..
We have already reached critical climate thresholds. As far as I’m concerned, it’s too late already to implement any of this mostly rubbish. If we are serious about climate change, flying should be banned, car factories should be closed down, all coal fired power stations should be closed, banks should be shut up, and people need to learn to live off the already installed renewable energy, and stop having kids. The problem remains consumption, and no capitalist wants to reduce consumption, they just want to turn it green.
There you go……  I didn’t even have to write a book about it.

Delusions of Grandeur in Building a Low-Carbon Future

31 01 2018

With many thanks from Ugo Bardi who first published this on Cassandra’s Legacy…… 

Some excerpts from Carey King’s excellent paper titled “Delusion of Grandeur in building a low-carbon future” (2016). By all means worth reading: it identifies the delusionary approach of some policy proposals. Image Credit: K. Cantner, AGI.

…. the outcomes of economic models used to inform policymakers and policies like the Paris Agreement are fundamentally flawed to the point of being completely delusional. It isn’t the specific economic assumptions related to the “low-carbon” transition that are the problem, but structural flaws in the economic models themselves.

There is a very real trade-off between the rate at which we address climate change and the amount of economic growth we can expect during the transition to a low-carbon economy, but most economic models insufficiently address this trade-off, and thus are incapable of assessing the transition. If we ignore this trade-off, or worse, we rely on models that are built on faulty premises, then we risk politicians and citizens revolting against the energy transition midway into it when the substantial growth and prosperity they’ve been told to expect will accompany the low-carbon transition don’t materialize. It is important to note that citizens are also told that doubling-down on fossil energy also only provides growth and prosperity. But this is a major point of this article: mainstream economic models can’t tell the difference. There are foreseeable feedbacks of a fast transition to a low-carbon economy that increase the risk of major recessions.

The AR5 indicates that if the world invests enough to reduce greenhouse gas emissions over time — such that total annual greenhouse gas emissions are practically zero by 2100 — to stay within the 450 ppm and 2-degree-Celsius target, then the modeled decline in the size of the economy relative to business-as-usual scenarios is typically less than 10 percent. In other words, instead of the economy in 2100 being 300 to 800 percent larger than in 2010 without any mitigation, it is only 270 to 720 percent larger with full mitigation. Meanwhile, there is no reported possibility of a smaller future economy. Apparently, we’ll be much richer in the future no matter if we mitigate greenhouse gas emissions or not.

This result is delusional and doesn’t pass the smell test.

Another flawed piece of the framework in the IAMs is that they assume that factors in the economy during and after a low-carbon transition will remain at or return to the statistically positive trends of the last several decades — the trend of growth, the trend of high employment levels, the trend of technological innovation. Those positive trends change over time, however, so it is faulty to assume they’ll continue at historic levels independent of the need for rapid changes in the energy system. They also assume that energy costs will not significantly increase over the long term. Further, they extrapolate trends in growth, employment and technology from the past and current carbon-based economy to apply to a future decarbonized economy in ways that represent guesswork at best, and ideology at worst.

Perhaps most importantly, IAMs do not consider the substantial negative feedback between high energy costs and overall economic growth. Negative feedback means that when one factor increases (energy prices, for example), another factor consequently decreases. Many of us know from practical experience that if gasoline costs too much — like when it was near $4 per gallon in 2008 — it may eat into our budget to such an extent that we can’t pay all our bills or can’t pursue hobbies. On a personal level, then, we see that increased gas prices cause decreased discretionary spending — a negative feedback. This idea can be extended to the entire economy’s budget and income.
….. the models currently answer a question that is barely useful: “If the economy grows this much, what types of energy investments can we make, and at what rate?” The models should address the question we really need to answer: “If we make these energy investments at this rate, what happens to the economy?”

There is a fundamental conflict between achieving low- or zero-carbon energy systems and growing an economy. Both the scale and rate of change during a low-carbon transition matter. So, let’s create macroeconomic models that can plausibly replicate historical trends of the most important energy and economic variables in times of high energy investment, recession and growth, so that we have confidence that we can ask relevant and informative questions about how low-carbon investments impact economic growth. Let’s stop deluding ourselves by using models that assume answers we want to see.

‘Eat Less Meat’ Ignores the Role of Animals in the Ecosystem

27 01 2018

Lifted from Civil Eats…… it’s fortunately what we were taught at the Small Farm Planning course, and it’s mercifully slowly catching on. My neighbour’s cows are currently on my land, building soil and reducing fire danger all at the same time.

Given the concerns over resource-intensive industrial meat production, you’d think the resounding message would be, “don’t buy cheap meat, buy good meat.”

Instead, a rule of thumb that has emerged in environmentalists’ circles is simply “eat less meat.” This statement frames meat as an indulgence rather than 1) the end result of an essential and timeless ecological process (the biological breakdown of vegetation, which feeds the soil and removes dead grass so that new vegetation can grow) and 2) a fulcrum in the way land across the world is managed or mismanaged.

As a grazier and land manager, I’m part of a growing group of people who have committed our lives to restoring the health of environments directly, through exquisitely precise grazing on sensitive land, and who depend on the support of our communities to do this work.

“Eat less meat” is a well-intended caveat amongst woke environmentalists (a group who is, after all, my cohort) but it has also become a primary barrier to me and others like me doing our work. And it’s hard to not take that personally. Because what could be more personal than the health of my watershed and the kingdoms that inhabit it? If these things aren’t personal to you, we have a bigger problem.

Our work goes like this: We memorize every nook and cranny of a piece of land like a lover’s body. We study how water flows across it and what grasses grow where. We plant trees where we’ve seen them grow before and could grow again. We spend unpaid hours moving animals exactly where they need to go to knock down encroaching brush on long-neglected land. We fence out bird nests. We leave areas ungrazed for a season—and can calculate the cost to the tune of hundreds of dollars—because we know in our throats, our chests, our bellies, and our bones (that’s where we feel it) that it needs another season to grow before grazing would be helpful. We get knocked down, kicked, cut up and cut open; we don’t just risk injury but accept its inevitability. We memorize the names of species that used to grow or live here but have been lost. We love the land and its inhabitants so much that we’re willing to work for next to nothing.

But martyrdom isn’t very becoming, and you can’t milk a dry cow; so like everyone else, graziers have to make money. Until environmentalists actually really put their money where their mouth is and pay me and others to graze land right without meat as the chief goal, we have to sell the surplus from our herds (the flesh of some of the animals) in order to be able to afford to feed ourselves.

Believe me, I wish I were a photosynthesizing autotroph who could get my nourishment directly from the sun.

Not all grazing is created equal. This is the essence of what gets missed in discussions about the impact of livestock agriculture on our local ecosystems and global climate. Decades of mismanagement has left a tough legacy for those of us grazing with restorative goals to overcome. But when animals are managed according to nature’s schedule, beautiful changes can happen fast.

Some of the year I graze the animals in tight bunches to lay down old grass to feed the soil. Other times, I’m herding them fast across the property to stimulate grass plants to grow denser and healthier while they pump carbon deep into the soil food web. I can stop erosion around streams based on how I move these big animals, and stabilize vulnerable hillsides through careful decision-making. For me and many like me, grazing is our art form—it’s our best tool for breathing new life into neglected land.

“Eat less meat” is about mitigating damage, and it misses the opportunity to tell people that there’s a way to actually benefit their planet. Industrially produced meat is unquestionably bad for the environment, and for animals. But perpetuating the myth that all meat is the same means that the potential benefits of responsibly raised meat never get a sufficient foothold. By telling only half the story, we’re perpetuating the problem because we never bother to mention the solution.


As an aside, few environmentalists who are opposed to grazing animals and eating their flesh have demonstrated either the degree of embodied affection, personal risk, and deep practice or the knowledge of grassland dynamics, plant succession, and wildlife movement that I’ve seen among the graziers in my life. So I urge those who care about the meat industry’s impact on the environment to bring more curiosity and humility to the discussion.

When we say “eat less meat” and end it there, we miss an opportunity to equip eaters with the means of sourcing protein that will not only nourish them but restore their home ecosystems. And behind every few hundred acres of land that goes poorly managed due to consumer miseducation is a land steward who can’t do their work.

Appetite is energy. Rather than try to halt the tide of appetite for meat by discouraging its consumption outright, a better way to steward that energy would be to concentrate on where it would it can do the most good. In doing so, we’re not just improving our environment, we’re widening the demand for graziers who can produce meat and serve as ecological service providers.

So don’t “eat less meat.” Eat meat from people whose hands you can shake and whose ranches you can visit. Eat as much of that as you can afford, because that stuff comes from extensive production systems that impact hundreds and thousands of acres. Sourcing your protein from places you can account for means you can verify that their pastures are also habitat for foxes, badgers, burrowing owls, and bears—that you are keeping land wild and free. As I see it, beef raised in its environs beats a bean field any day as an ecologically just source of protein.

This type of meat isn’t cheap—and you might find that you value it differently and stop taking it for granted. The end result may very well be that far less meat is consumed overall, at least for a while. But the quantity doesn’t matter to me—what matters is what that animal did in its life on earth.

We have to pay for the world we want to live in. This means consuming the flesh of other sentient animals may damn well require a line-item on our budgets, alongside “eating out” and “entertainment.” Maybe it’s time we socialized ourselves and others to budget for environmental activism, and use that money to buy meat produced by the soil-building, grassland-loving graziers in our communities.

The Selfish Green

14 01 2018

Every now and again, a video pops up in my newsfeed that I really really look forward to watching. This was one of them…… but oh what a disappointment…..  Sometimes, and I know I am not, I start believing I am the only one who ‘gets it’ and sees the whole picture. Well 99% of it, I’m certain I’ve missed something.

While there’s no doubting the eminence of the panel of four, David Attenborough, Richard Dawkins, Jane Goodall, and Richard Leaky (of whom I hadn’t really heard of much before…), I thought they fell far short of understanding the issues – no, predicaments – we are facing.  None of them seem to know much about energy, or the monetary system, with the fat cat lookalike, that Leaky fellow I didn’t know much about, really displaying his ignorance of nuclear energy.

What’s plain to see after watching that lot is that we are truly stuffed, notwithstanding their collective optimism, which as you probably all know, I don’t share……  a pessimist is, after all, a well informed optimist…!

Leaky’s wish to monetise every aspect of the environment so it can be saved really takes the cake. Money is the problem after all, which thankfully Attenborough points out to him, even if it’s just as an aside.  I love Jane Goodall to bits (and her chimps – there’s a wonderful clip of a couple with a Jack in the Box), but she’s frankly a bit naïve.  Dawkins is interesting, as always, but has no grasp of the financial and energy problems at all, in fact says nothing whatever about it.  Attenborough is the best informed of all, he has after all seen how the planet has changed in the past 60 years more than anyone else, and at least he realises we are way overpopulated……..  at the end, they all roll around in hopium. I’d love to know what DTM followers think……

That this video has only had 187,634 views as I type says it all.  Does anybody care?


Extreme climate, here we come…..

5 01 2018

As this blog starts attracting climate deniers, climate change is causing havoc all over the planet.  Hardly surprising really, because adding more energy (heat in this case) to a dynamic system like the planet’s climate was always going to cause more and more energetic results and extremes…..

cold storm bombWhile North America is about to experience a cold weather bomb, with atmospheric pressure predicted to drop to 962hPa – which if it happened in the tropics would almost certainly cause an upgrade of cyclone/hurricane classifications – resulting in sea level surges, flooding, 100km/h winds and temperatures dropping as low as -40C….

From climate reality project dot org….

The US East Coast is experiencing an “old-fashioned” winter, with plenty of cold weather and some heavy snowfall in certain places. Listening to climate contrarians like President Donald Trump, you might think this constitutes the death knell for concern over human-caused climate change.

Yet, what we were witnessing play out is in fact very much consistent with our expectations of the response of weather dynamics to human-caused climate change.

Dr. Michael Mann on Extreme Weather: “We Predicted This Long Ago”

Let’s start with the record five-plus feet of snowfall accumulation in Erie, Pennsylvania, in late December. Does this disprove global warming? “Exactly the opposite,” explains my colleague, Dr. Katharine Hayhoe of Texas Tech University. 

Global warming is leading to later freeze-up of the Great Lakes and warmer lake temperatures. It is the collision of cold Arctic air with relatively warm unfrozen lake water in early winter that causes lake effect snows in the first place. The warmer those lake temperatures, the more moisture in the air, and the greater potential for lake effect snows. Not surprisingly, we see a long-term increase in lake effect snowfalls as temperatures have warmed during the last century (see figure below).

Moreover, while we’ve seen some cold weather in the eastern half of the North America (see the pattern for New Year’s Day below), the western half of North America has been unusually warm. Indeed, most of the Northern Hemisphere, and the globe overall, have been unusually warm. That’s why we call it global warming, folks.

Right now, it’s actually warmer in Alaska than Florida; and some people believe it’s caused by sunspots.

And where’s all that heat gone?  AUSTRALIA….!  we are expecting a heatwave, starting today in Tasmania in the mid 30’s but worsening to well over 40C in Sydney this weekend.

The Bureau of Meteorology (BOM) is urging Sydneysiders to “check up on their elderly neighbours” on Sunday, with the mercury expected to reach 45 degrees Celsius in some parts of the city.

Several areas in Sydney’s west are predicted to swelter through the weekend, with highs of 45C in Penrith, 44C in Richmond and 43C in Liverpool, Blacktown and Campbelltown.

The CBD and eastern suburbs will not be immune, with the bureau warning temperatures in those areas could top 40C.

“Heatwaves can particularly affect vulnerable people, so the sick, the elderly and children,” BOM duty forecaster Rob Taggart said.

And all this weather chaos is already affecting the price of veggies here in Australia. Here in Tasmania, we’ve had really unseasonal wind, the likes of which usually occur in Spring, not Summer.  In fact, our Summer has been more like Spring all along, with just a couple of hot days, and lots of rain to go with the wind. It’s hammering my snow peas which are definitely not producing as well as last year.

A northern New South Wales vegetable grower is warning that warm temperatures could see prices rise at the supermarket, as South-east Queensland and northern New South Wales are in for several sweltering days with temperatures in the high 30s as extreme heat from Queensland’s west makes its way across the state…..


What will it take to avoid collapse…?

ANDREW GLIKSON. Parliament and the media cover up the looming climate crisis

13 12 2017

By some coincidence, I listened to a podcast from Radio Ecoshock in which Andrew Glikson was interviewed on this very subject…… I lifted this article from John Menadue’s blog.

Sometimes it is what is not mentioned, or little-mentioned, rather than widely discussed, which tells the story.


Dr Andrew Glikson

The Section 44’s citizenship issue and the marriage equality issue have recently dominated the Federal Parliament. However, with a few exceptions, the looming global warming crisis, to which Australia is contributing over four percent of global greenhouse gas emissions (including coal and gas exports), is hardly mentioned in Parliament and is markedly subdued in the media.

This is surprising when CO2 emissions are accelerating at 2 to 3 parts per million per year, and global heating and mean global temperatures have reached 1.3 degrees Celsius above pre-industrial levels (NASA Goddard Institute for Space Studies, 2017). These changes have produced a spate of extreme hurricanes (cf. Caribbean, Texas, Florida, Philippines, Fiji) wildfires (cf. southern Europe, California) and floods (Pakistan, China) around the world .

Despite an ongoing campaign of untruths by climate denial lobbies, the world’s leading climate research organizations (NASA, NOAA, NSIDC, Berkeley Earth, Potsdam Climate Impacts, Hadley-Met, Tindale, CSIRO, BOM) have confirmed current trends toward a world of +2 degrees Celsius and +4 degrees Celsius above mean pre-industrial temperatures.

According to leading authorities in climate science, including Hans Schellnhuber (Germany’s chief climate change adviser), James Hansen (NASA’s former chief climate scientist) and others, at +4 degrees Celsius above pre-industrial temperatures, large parts of the world will become uninhabitable, due to extreme weather events and rising sea levels inundating coastal regions and low river valleys.

But the silence of the political classes is hardly surprising, given both major parties support, or at least tacitly support, coal mining, and coal and gas export. Thus: “Bill Shorten told reporters on Monday that, if the Adani project cleared all the regulatory hurdles, ‘then all well and good’”, negating Kevin Rudd’s assertion that climate change is “The greatest moral, economic and social challenge of our time”.

Even some Greens appear to regard too much focus on global warming as a vote loser, aiming instead to be a broad-church left-wing party rather than a climate change-focused effort.

To a major extent, these parties are the product of a media in the thrall of the denial syndrome. Thus, even the ABC, when reporting large-scale extreme weather events around the world rarely, if ever, relates them to global warming, which drives increased energy levels in the atmosphere-ocean system, which triggers hurricanes and wildfires.

There is not one climate scientist in the Australian Parliament. The media commonly shuns the views of scientists. For example, the bulk of the mainstream media recently shunned an open letter to the PM signed by 200 scientists and communicated to the press. Further, many progressive journals appear to suffer from “climate fatigue” and regard climate communications as no more than “nuisance value”.

This is the way the world ends. Not with a bang but a whimper.” (T.S. Eliot).
