    The Jevon's Paradox is a Myth

    In the physical world the consumption of material resources is a necessary activity for sustaining physical life. In the mid 19th century, humanity discovered that the use of mechanical implements allowed for more efficient resource production and material abundance. In this time, childhood mortality was rampant and the population was food and energy resource-scarce. It was so resource scarce that real physical population limits were being materially enforced through the mechanisms observed by a period researcher in political science named Robert (bobby) Malthus. Bobby's theory was that in any given environment a population "check" would occur once the material resource limits were attained in any given region. Not really difficult to understand, this work was groundbreaking because he applied it with scientific precision to the human species as simply another form of herd animal.

    Two specific machines that were created during this time created the impetus for massive population growth by freeing up material resource for consumption. The first was the implementation of a machine that would plant seeds at the appropriate depth and spacing and in physical rows. This device was called a "seed drill" and is basically the reason that the plow was invented. By growing row crops, the greater efficiency of food production allowed for more abundant food supplies for the same amount of invested energy. Therefore the "efficiency" of food greatly increased.

    The second machine that was equally responsible for the explosion of population during a period of time that would later be called the "industrial revolution" is the pulsometer pump created by an engineer named Charles Henry (Chucky) Hall. Chucky found that by allowing for the expansion and contraction of the volume of steam in metal cylinders one could create sufficient vacuum force and use the power of suction to remove water from accumulating in coal mines. This machine greatly increased the access of humanity to deeper coal mines and allowed for a much more efficient extraction of coal.

    After this invention a schoolboy noticed that the piles of coal being placed in his family chute for the warming of his flat was becoming cheaper and cheaper, so they decided to burn more of the coal to allow for a much more comfortable environment. Later on, this schoolboy came up with an idea that if any resource is made to be cheaper then the resource would be consumed at a higher level, growing without end. Of course his idea was revolutionary at the time because nobody else on the schoolyard gave a damn about such trivial pursuits and would rather address their time and energy kicking hard rubber balls on the pitch and pulling girl's pigtails. Jevons though himself quite a smart little lad!

    However, being just a simple schoolboy, his understanding was limited to his extremely myopic period and limited exposure to the world. His fanciful projection of unlimited consumption increases occurring at increased efficiencies of material resources, or in the case of food, unlimited population growth and increased material resource consumption would always hit a limit.

    In the modern world then, the concept of energy efficiency is often attacked by disciples of Bobby Malthus who wish to assert that in the current world's resource system, we have or are fast approaching a population "check". They want to assert this kind of "disaster porn" scenario so intently that they make up cute acronymns like EROEI and tend to have invested heavily in wooded land in remote parts of their respective countries where they like to do crafty things like bury schoolbuses as bomb shelters and store canned goods and ammunition. They also tend to like post apocalyptic science fiction scenarios that usually include zombies and guns.

    In the real world, the Jevon's paradox doesn't exist, at least not in the simplistic schoolyard view of a 9 year old boy. In the real world of energy efficiency, the residential energy efficiency gains for low-income sectors do experience a 'takeback' of energy efficiencies. This is due to the resource constrained nature of the low-income experience. This is also the environment that is the most analogous to the mid 19th century school-yard experience of Jevons. This low-income takeback has been widely studied and can be accurately assessed to be between 15% and 25% of total efficiency gains in a household.

    Similarly, in industrial applications, arguments have been made with varying success to indicate that any production efficiency would naturally lead to price reductions and consumption increases, to an unlimited degree so that any increase in efficiency would naturally lead to increased material consumption, without out end. This, of course is laughable as there are limits to economic growth and consumption.

    The physical nature of modern economy is fraught with improvisations placed upon the collective understanding by those who wish to maintain control of our labor and resources. The most insidious of these falsehoods are those regarding organized religion and modern economics. Of course these are basically the same thing. One believes in an invisible entity and the other believes in an invisible hand that will magically balance out the inherent assumptions being made by dimwitted theoreticians. Similar to the oil-industry myth that oil consumption (or even CO2 production) is a proxy for economic activity, the idea that all energy efficiencies must be met with equal increases in consumptions similarly relies on such magical thinking. The real-world examples of per-capita annual driven miles under price fluctuations in gasoline and the differences in energy intensity (joules per $ GDP) among different societies are only a few of the literally millions of real-world examples that disprove the Jevon's Paradox's null hypothesis.

    I've been covering IPCC reports for 20 years so I've got a pretty good handle on them. And what I'm reading in this one is eye-opening in a lot of ways. So to all my reply guys who are like "well don't you already know what's in the report, things are still bad," I say actually what's in this report are the seeds for revolution, so let's take it all in shall we?
    Throughout the month of April, I'll be posting weekly installments (at least) of analysis on this report, sometimes accompanied by bonus podcast episodes, sometimes not. These posts will be free, so feel free to forward or share. If you run a media outlet you're welcome to re-run anything, with appropriate attribution. If you feel so inclined, you can sign up for a paid subscription here, or via the button at the bottom of this post. Okay, here we go!

    Global team of scientists determine 'fingerprint' for how much heat, drought is too much for forests
    https://phys.org/news/2022-04-global-team-scientists-fingerprint-drought.html

    Just published in the journal Nature Communications, the study compiles the first global database of precisely georeferenced forest die-off events, at 675 locations dating back to 1970. The study, which encompasses all forested continents, then compares that information to existing climate data to determine the heat and drought climatic conditions that caused these documented tree mortality episodes.

    "In this study, we're letting the Earth's forests do the talking," said William Hammond, a University of Florida plant ecophysiologist who led the study. "We collected data from previous studies documenting where and when trees died, and then analyzed what the climate was during mortality events, compared to long-term conditions."

    After performing the climate analysis on the observed forest mortality data, Hammond noted, a pattern emerged.

    "What we found was that at the global scale, there was this consistently hotter, drier pattern—what we call a 'hotter-drought fingerprint' – that can show us how unusually hot or dry it has to get for forests to be at risk of death," said Hammond, an assistant professor in the UF/IFAS agronomy department.

    The fingerprint, he says, shows that forest mortality events consistently occurred when the typically hottest and driest months of the year got even warmer and drier.

    "Our hotter-drought fingerprint revealed that global forest mortality is linked to intensified climate extremes," Hammond said. "Using climate model data, we estimated how frequent these previously lethal climate conditions would become under further warming, compared to pre-industrial era climate—22% more frequent at plus 2 degrees Celsius (plus 3.6 degrees Fahrenheit), to 140% more frequently at plus 4 degrees Celsius (plus 7.2 degrees Fahrenheit

    Juries keep letting Extinction Rebellion off the hook — here’s why | Evening Standard
    https://www.standard.co.uk/comment/juries-judges-extinction-rebellion-innocent-just-stop-oil-protests-climate-activists-b992610.html

    When it came to our turn to defend ourselves there were limits to what we could say. We were allowed to talk about who we were, what we had done, and why. We couldn’t give a lecture on the disaster of climate breakdown, but we could speak about our ‘subjective belief’ that it was taking place. Similarly, we couldn’t tell the jury about Shell’s wickedness, how it had lied for decades about what it knew about the effects of burning fossil fuels, and the damage its drilling had done to environments and communities around the world, but we were allowed to say why we wrote what we did on the walls of the company’s HQ. Each of us is a different character, and each of us had a different story to tell.

    It is a strange, quite primitive experience to face a jury of your peers and explain your actions to them directly – the way I imagine it might happen in a tribe or a mediaeval village. With the mystification of the law removed, it was an intensely personal interaction, even with the judge’s many interruptions. Our jury reflected the diversity of London: mostly young, ethnically diverse, the majority women. I felt glad to be in their hands.

    After the jury cleared us, some of the press coverage commented on our ingenious tactics. But they were no such thing. There wasn’t even much by way of eloquence or persuasion. What happened over the two weeks was that we shared something with the jurors – our understanding of the science, yes, but also our vulnerability, our grief at what was happening to the planet and the people who live on it, and our gratitude to them for listening.

    The damning fact is that once I finish writing this column and you finish reading it, you, me and the rest of the world will likely return to our regularly scheduled stuff while we keep whistling towards a dead end – literally.

    These days, we prefer to talk or read about a slap at the Oscars rather than talk about, let alone read, another thick report which joins a bookcase of other thick reports that make a familiar point: if the rich, “developed world” does not cut the carbon pollution it spews into the atmosphere, then we will tip into the abyss and no one – however rich or comfortable they may be – will be able to find the emergency exit door.

    The periodic reports of the U.N.’s International Panel on Climate Change are lapsing into self-parody.
    This is your last warning, they say. Get a move on. Don’t sit idly by. Fix the problem now.
    We mean it!

    I am continually amazed that the IPCC scientists don’t throw up their collective hands in disgust at humanity’s inability to awaken from its slumbers and stop issuing reports altogether.

    Food Waste
    https://ec.europa.eu/food/safety/food-waste_en

    In the EU, around 88 million tonnes of food waste are generated annually with associated costs estimated at 143 billion euros (FUSIONS, 2016). While an estimated 20% of the total food produced is lost or wasted, 33 million people cannot afford a quality meal every second day (Eurostat, 2018).

    Globally, approximately a third of all food produced for human consumption is lost or wasted (FAO, 2011). FAO’s Food Loss Index (FLI) estimates that globally, around 14 percent of all food produced is lost from the post-harvest stage up to, but excluding, the retail stage

    ...

    support the fight against climate change (food waste alone generates 8-10% of global greenhouse gas emissions (UNEP Food Waste Index 2021))

    ...

    Factors contributing to food waste include:

    -Insufficient shopping and meal planning
    -Shopping environment (e.g. promotions like "buy one, get one free" that may lead to impulse buying and over-purchase)
    -Misunderstandings about the meaning of "best before" and "use by" date labels leading to edible foods being thrown away
    -Insufficient food management skills (e.g. meal preparation, use of food/food ingredients in-stock, use of leftovers)
    -Packaging difficult to empty or too large
    -Aesthetic considerations (bruised fruit and vegetables etc.)
    -Standardised portion sizes in restaurants and canteens
    -Difficulty in anticipating the number of customers (a problem for catering services)
    -Stock management issues for manufacturers and retailers
    -High quality standards (e.g. for produce sold at retail)
    -Overproduction or lack of demand for certain products at certain times of the year
    -Production errors, products and/or labelling not meeting specifications
    -Product and packaging damage (farmers and food manufacturing)
    -Inadequate storage/transport at all stages of the food chain including households (e.g. refrigerator temperatures)
    -Lack of knowledge and/or misinformation on the environmental, social and financial impacts of food waste
    -Low perceived value of food
    -Busy lifestyle and conflicting priorities

    jeste bych doplnila point z toho Termination Shock, ze ono totiz jeste zalezi na tom, odkud presne se ta sira strili. Sira strilena z Texasu ma jine ucinky nez z Filipin. Nejde o plosne otaceni termostatem, ale o ovlivnovani ruznych casti sveta ruzne. Podle Stephensonova nazoru se kolem toho daji ocekavat solidni valky (jeden stat nekde neco strili a na druhe strane planety to ovlivni monzun atd)

    YMLADRIS: zrovna sira je zajimava, protoze v lodni doprave mam za to ze probehlo vyrazny odsireni, coz je jeden z tech aerosol masking efektu, tj. odsirujeme, podobne jako budeme elektrifikovat, ale to vede ke zvyseni teploty

    TUHO: IPCC is like Stephensonova romanova zapletka (ruzny narody a skupiny chteji a nechteji strilet siru do ovzdusi) is legit

    The report says that solar geoengineering “may also introduce novel risks for international collaboration and peace”. It continues:

    “Conflicting temperature preferences between countries may lead to counter-geoengineering measures, such as deliberate release of warming agents or destruction of deployment equipment. Game-theoretic models and laboratory experiments indicate a powerful actor or group with a higher preference for SRM may use [aerosol release] to cool the planet beyond what is socially optimal.”

    Sorry but I must note that it seems incredibly problematic that the IPCC chair was previously Exxon's economist, and one of the two Coordinating Lead Authors of the cross-sector chapter is a senior staffer of Saudi Aramco, and the review ed for the energy chapter works for Chevron.
