50 years of history and 50 years of future - The Limits to Growth in a long-term perspective

In this lecture Jorgen Randers describes global developments since 1972 and compares them with the infamous scenarios from The Limits to Growth. He proceeds to describe what should be done to create a better world over the next 50 years.

    I think mister Randers too optimistic when he said collapse can be prevented with extraordinary effort. This level of effort world needed 50 years ago, and today SW is impossible, world went out of the limits before I born in 1992. So how can we talking about sustainability when we are totally unsustainable? Sust-ty = 1,0 Earth (or less, economic growth = destroying of biosphere potential). And not 1,8 Earth. 1,8 - 0,8 = collapse-scale reduction of human enterprise. BAU (peak 2015-2025). TINA. Any damn way, I proud for Randers, Meadows, Gaya Herrington etc. Really great people.

    The aside near the end of the video about a predicted 5 degree Celsius temperature rise is a global disaster in and of itself. If one looks at the IGCC climate report on what a world 4 degrees warmer will look like, most of the world will become an inhospitable desert and the only temperate regions will be Canada and Russia. Check out the KZread channel "Real Life Lore" and the video "a world 4 degrees warmer" if you prefer video essays.

    @@em945 I don't know what "fake websites" you refer to. Everyone who is the least bit geologically literate (which apparently does not include you) has heard of the Holocene Thermal Maximum. It is standard mainstream science. And the Vostok ice core clearly shows that it is temperature that drives CO2 and NOT the other way around, at least at levels that have prevailed for most of earth's history. This is all published in mainstream scientific journals. It is logical that CO2 AT VERY LOW LEVELS would raise temps because it can trap light of a particular wave length, but current levels, even though they are still low in terms of geologic history, are high enough that astronomers can observe that the light is almost entirely saturated so that there is no more light of that spectrum for additional CO2 to absorb. It is the sunlight, not the CO2 itself, that creates the so called green house effect. Since we cannot increase the amount of light of that spectrum that is emitted by the sun each day, we cannot increase the earth's temperature by emitting more CO2. I think the difference between AGW skeptics/deniers and AGW True Believers, is that True Believers have sky high deference for authority figures, while skeptics and deniers look at the data and think things over for themselves. The latter tend to be critical thinkers while the former tend to be easily bedazzled by status markers.

    Dear Jorgen. First of all a great pleasure and respect to 'meet' you as co-author to the premise in 1972 that should have been. My great concern is that 'economics', perhaps, as an ideology to explain and solve is far too general and excludes 'externalities' and cultural bias... Furthermore, progressive economists would explain that infinite growth on a finite ecosphere for terrestrial resources where we understand to have near infinite energy abundance is not pursuant to GDP in any sense... I absolutely agree with you regarding democracy to realise our dilemma. My conclusion too, if we are to make a paradigm change to Kardashev 1. As long a we discuss our world in financial trends we have a problem.

My suggestion is taking ones failures into account and grow, not double down on the failures to make more of them and get more policies implemented that ruins society for everyone.

    Yes. Check out Gaya Herrington's analysis using real-world data that she did while working at MIT. To whatever degree the most influential people in the world have paid to this problem, it seems that they have decided to put the bulk of humanity's resources behind achieving "comprehensive technologies". If global civilization fails at this, then the result is a closest fit to the Bau2 scenario. I also recommend the work of Nate Hagens. Contemporary economics only takes into account the energy and resources *available to humans*. It doesn't concern itself with the idea that once earth's resources are "fully exploited", the only direction left is a massive upward price spiral and economic collapse.

    The Earth 4 model seems to forecast a decline in population (related to higher living standards) and an almost mirrored increase in wellbeing. Somehow it seems not to take into account the huge negative socio-economic effects of a colossal inverted global population pyramid. Our social healthcare and welfare systems are built on the same model as a Ponzi scheme (I don't want to claim they hold similar intents, obviously!) and once the influx of new members (or providers) into that scheme sinks below a given minimum, it starts to collapse. I can't see how that scenario could correlate with social wellbeing. Also, the plot seems very much focused on human metrics, and the "earth" as a whole (after which it's ironically named) seems only represented in "observed global warming", which is just a small fraction of our planet's problems and in fact just a symptom of the overarching issue: Overshoot. So, why isn't there more focus on resource depletion and resulting pollution in the graph shown? If GDP keeps indeed increasing till 2080, these must be serious enough issues to address, as they eventually will lead to collapse anyhow and topple the argument that we as a species can somehow, with huge effort, steer the ship out of the coming storm.

    I strongly dispute that warming is a problem. COOLING is a problem. Warming makes survival easier. Just look at the historical record. Compare the GISP2 ice core with the ups and downs of civilization. Activists have the climate threat totally upside down. A hundred years ago, when far fewer people were second generation or later urbanites, this was universally understood. Now we have more data to confirm it than they did, yet the narrative has been turned around in defiance of both data and experience. At the risk of making it too complex, I think the model needs to account for cyclical climate change which occurs naturally with an adverse weighting for cooling periods which inevitably recur, to treat energy and minerals as separate factors, to include depleting ground water as a separate factor, to focus specifically on endocrine disruptors rather than pollution in general, and to incorporate declining general intelligence (which reduces adaptive capacity and is associated with much higher rates of social dysfunction), and political instability related to ethnic diversity. The global debt burden will also be a factor which inhibits adaptation, but I don't know whether it can be modeled realistically or not. Also, interlocking "networks of networks" increase the risk of collapse, but again I don't know whether we understand how to make them work in the model. And overconcentration of the population in giant urban centers far from essential supplies, the complexity and fragility of global supply chains, and decaying infrastructure that requires energy to repair and maintain. I know you can't model everything, but we should be aware that these other interacting factors make the risk of catastrophe considerably greater than even the model suggests.

    I am disappointed in the quality of this analysis. He is diverting attention from the most serious problems by focusing on the global warming boogeyman. In fact, both history and prehistory consistently indicate that a warmer world would be a better world, as would a world with more CO2 regardless of temperature. Unfortunately, temperature fluctuations in the last hundred years are almost entirely explained by natural phenomena which man has no control over, and after the high solar activity of the late 20thh century, a cooler phase of the climate appears to be developing, which is bad, very bad. Cooler, not warmer, temps are associated with more erratic and extreme weather both statistically over historic and prehistoric time and for reasons that are well understood in meteorology. Unfortunately, cyclical climate change is a very important factor that is omitted from the model. Randers says food production has increased, which is true, but fossil fuels are what has made that possible, which he fails to mention. He also says that fossil fuels are much more plentiful than we expected 50 years ago, but I do not believe the evidence supports that at all. It is extremely unlikely that we will discover vast new reserves of minerals to make the green economy daydreams a reality. ESG advocates consistently ignore the immensity of mineral resources to make their green sci fi dreams come true, just as they ignore EROI issues (which may be partially offset but do not go away simply by building more PV cells and wind turbines, even if we had enough minerals to scale up as much as needed). Innovation per capita has been declining since the late Victorian Age, and the "capita" part will soon be falling as well. He mentions that fertility is down, but ignores that the decline is concentrated in the educated classes which, given the known high heritability of intelligence, will further reduce innovation as well as good decision making in positions low and high, and greatly increase the amount of social dysfunction in society. The biggest falls in fertility are in the social classes and ethnic groups that produce almost all of our adaptive innovations. He also does not mention the ongoing effects of endocrine disruptors on both wild animal and human health and fertility. I suppose that is one way to reduce the population, but it is a very cruel way, and it may collapse the population at such a catastrophic rate at some point that it adds to the problems. But the model seems to have been shifted to vastly overweight CO2 while vastly underweighting endocrine disruptors. He also ignores social factors during the collapse, one of the biggest of which is ethnic diversity which throughout history has repeatedly provided the lines of conflict within states along which the population split, not infrequently erupting into internal warfare, as we have seen in Yugoslavia, Iraq, Syria, Sri Lanka, Sudan, Ukraine, and Afghanistan to name some of the most high profile examples of the last 30 years. I checked Jorgen Randers' bio and he made his career in big business and apparently, like many persons of influence in western countries, has been on the payroll of the growth mad CCP since 2019 (wikipedia: "In 2019, Randers was appointed as inaugural co-chair of the Ecological Civilization Center at Peking University's Research Institute of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era"). He may be soft pedaling the dangers, consciously or unconsciously, for these reasons. A public message of impending tragedy does not play well with the monied interests.

    @@matijabl "How can one know gw is boogieman?" It fits the definition: a greatly exaggerated or imaginary threat (originally Napoleon Bonaparte, "the Boneyman" which became Boogieman) used to scare children or other gullible persons. "Mammals survived ice age before," Many of them had to migrate to survive, resulting in ecological configurations strikingly different from those we know today, and some of them did not survive. The onset of ice age conditions is frequently accompanied by extinctions. Populations expand their numbers and ranges under warmer conditions (such as the tripling of the polar bear population during the late 20th century warming), precipitation increases, and deserts shrink. Storms also become less severe. (Hurricanes may or may not be an exception to this rule. There were certainly some very big ones during cool periods. SST may not be the only factor that affects them.) All this stuff goes in reverse when the climate gets cooler. "it is easier to warm up than to cool down." Look at the data. Way more cold related deaths even in routine winters than there are heat related deaths during severe summer heat waves that make national or international headlines. Yet only heat related deaths get media attention, while the much greater cold related deaths are ignored. "Louis Pasteur stuf on my mind, it does not have to boil, just prolonged elevated temp and you get a nice clean sterile planet." If that were true, the Amazon rain forest would be sterile! It never gets cold there, elevated temperatures all year round. The truth is that life on earth thrives wherever liquid water is abundant and sufficient minerals are present (some parts of the ocean have low mineral content and thus low populations). Geologists tell us that for about half the history of life on earth, temperatures were 8.5C (15F) degrees warmer than today. Warmists are trying to scare us with the alleged threat of a 2 degree C temperature rise (we should wish for it!) although it is well known in geology that temps were already 2 to 3 degrees C warmer during the Holocene Thermal Maximum around 8000 years ago. The entire period of elevated temperatures lasted between 3 and 4 thousand years and is also called the Holocene Thermal Optimum. Our ancestors were still in the stone age, but agriculture expanded rapidly, animals were domesticated and crops improved, early cities thrived and the first preliterate states appeared. No record of whether they were wringing their hands in anxiety over the "threat" of melting permafrost and methane outgassing. If you look for an image of temps derived from the GISP2 Greenland ice core, you will see that civilization thrived during warm periods but that the coldest periods correspond with the Bronze Age collapse and subsequent Dark Age, the fall of the West Roman Empire and the subsequent Dark Age, the "calamitous 14th century" as Barbara Tuchman called it and general troubles that marked the end of Medieval civilization, although we skirted another dark age because of new technologies and new crops (especially the potato). "Check out moist greenhouse self arrest... It seems it is warming pretty quickly here on earth" You would certainly think so from listening to scientifically illiterate journalists, politicians, and celebrities, none of whom ever verify or investigate their sources, but the reality is that the warming was concentrated in the 1980s and 1990s and since circa 2000 there has been very little change in temperature in either direction. "I dont like cold either but its easily fixed with a log in grate." And how do you cope with crop failures and food shortages? Historians estimate world population contracted about 10% during the Dalton Grand Solar Minimum and about 25% during the earlier Maunder Minimum (when the first English settlers arrived in North America).
