"Manufactured risks are the product of human activity." Ulrich Beck

" A "risk society"
is a sociological concept describing a stage of modernity where society is increasingly defined by and organized around managing the hazards and insecurities it has produced itself through modernization and industrialization.

Self-produced risks: The primary source of risk is not nature, but human actions and the unintended consequences of modernization itself.

Individualization: Individuals are increasingly forced to confront these risks personally, with a greater emphasis on individual choice and responsibility in the face of larger, systemic problems

Ulrich Beck defines it as "a systematic way of dealing with hazards and insecurities induced and introduced by modernisation itself". "

" The Study of Existential Risk
frames the rises and falls of civilisation around the idea of the “Goliath”, a hierarchy that dominates labour and energy through coercion and violence."

"Our research shows how there are nascent attempts to embed citizens into decision making by re-plumbing democracy, flattening hierarchies and constructing more dynamic feedback loops that have real consequence."

We live in a society where constructing gigantic datacenters the size of small cities is considered vitally important for whole countries and the world. These datacenters consume vast amount of resources in their construction and when they are in operation. Energy, water, concrete, plastics, metals and more.

The expected average lifespan is projected to be 3-4 YEARS. 5 at best. After that point they will be completely obsolete. They will have to be demolished entirely and built anew. No one makes a big deal out of that.

These datacenters are used to provide so-called AI and crypto. No one really needs AI, we have managed things pretty well up to now without it up to now. Crypto is a scam. All of these resource are being used to extract more money from everyone's pockets and put it in the pockets of the mega-wealthy techbros and the corporations they control.

We also live in a society where the overwhelming majority of coral reefs in the worlds oceans are bleached and dead. Its almost certain they will never recover naturally.

The death of all the coral reefs is designated as the world's ecosystem crossing a planetary boundary. A line in the sand. It is a stark warning to everyone on the planet today.

It is thought that with a great deal of work and effort we could restore the worlds reefs to something approaching their original state. They can never be the same as untold species will be lost forever.

We can find a way of making something work. Lots of people working to grow corals in nurseries in tanks then divers transplanting the young corals into gardens under the sea and becoming underwater gardeners tending the reefs. You may have seen all this in a documentary or two.

The work requires a great deal of manpower but it does not require a lot of resources like energy, plastics or metals. There are plenty of indigenous islanders around the world who would love to restore their reefs with the help of experts from elsewhere.

Guess which of the two will benefit each and every single person on the planet? Guess which one costs the most? Guess which one has the longest projected lifespan? Guess which one receives the most attention in the media? Guess which of the two will actually be done? Go on, take a wild, crazy guess. I dare you, I double dare you motherfucker. Take a guess.

WE. ARE. ALL. FUCKED.

May the all gods and goddess' help us. Jesus wept etc.

The global appeal of the doughnut

This week it’s the now annual Global Doughnut Days, hosted by Kate Raworth and her Doughnut Economics Action Lab. There are events happening around the world and online, exploring and investigating the ongoing work around doughnut economics. As my own contribution, I thought I’d check in on how the doughnut is being applied around the world.

As a refresher, Doughnut Economics is a way of conceptualising global challenges. It was developed in the NGO world and popularised in Kate Raworth’s 2017 book, which I reviewed here at the time. Raworth builds on the idea of planetary boundaries, noting that as well as a set of environmental limits that we shouldn’t exceed, there are also social limits that we shouldn’t fall below.

Countries can fail by overshoot – too much carbon or pollution. They can also fail by shortfall – not enough education, healthcare or political freedom. We can put social and environmental limits together to give us an upper boundary and a lower boundary. Humanity thrives in the safe space between these boundaries.

A doughnut isn’t the only way to picture these boundaries. It’s not even the most intuitive, which would probably be to call them a floor and a ceiling. But it is the most fun way to describe them, and that’s the gift of the idea. Not many people are interested in economics. Everyone likes doughnuts. You would struggle to rally a group of ordinary citizens to discuss the trade-offs between environmental and social targets in their local economy. But you might get them to come to a workshop on doughnut economics.

Lots of different places have now done exactly this, using the doughnut idea to explore the challenges of their particular city, region or country. Amsterdam were the first, and it has now spread far and wide:

The map above shows 50 different places that have used the doughnut in local government. The fact that this is local government and not community groups is a clear testament to the doughnut’s practical use, to my mind. This works. It works for decision makers and can lead policy making.

The map here is drawn from a recent study in the Journal of City Climate Policy and Economy. The researchers looked at these 50 places and what effect the doughnut had, looking at the sorts of policies the approach was generating. They found that the doughnut was useful for getting different departments working together, as they could see how their specific objectives contributed to a whole. It breaks local governments out of their silos and builds a shared understanding of what good lives look like in the city. Everyone’s work matters – the environmental team, the education department, those working on inclusion or urban planning or economic strategy.

It also prompted cities and regions to monitor different forms of progress. GDP won’t be enough, and the doughnut approach is ‘agnostic’ about growth – postgrowth rather than degrowth, if you like. Human thriving can only be measured across a range of different metrics, and so regions using the doughnut need to gather different sets of data.

Interestingly, the research found that doughnut economics programmes were proving useful enough to last. Of the 50 places surveyed, only two had dropped the idea with the end of the political term. Others had continued or been tweaked. Most are too early to tell just yet, but the doughnut seems to work for the political centre as well as the left.

As to whether it’s a truly global idea, that needs more time and my title may be jumping the gun. There’s only one example in Sub-Saharan Africa so far, and it’s atypical: Cocody is an up-market suburb of the city of Abidjan in Côte d-Ivoire, and wouldn’t represent the priorities of the wider city, let alone the country. There are five projects across the whole of Asia. Portland and Philadelphia were early adopters in 2019, but it’s noticeable that no US cities have followed their lead in the last five years.

On the other hand, this is the just the 50 locations in the study. DEAL are working with many more local governments that weren’t part of the study, and so the map doesn’t reflect the wider influence of the idea.

In short, the doughnut works. We can’t say just yet if it translates everywhere, but it certainly works in lots of different places. There are plenty of examples of its practical usefulness. If you want to apply it where you live, the action lab has all the tools you need to get started.

#EU-Parlament stimmt für Verbot von „Veggie-Burger“ und „Tofu-Schnitzel“

PIK_climate: Die Lebensmittelproduktion ist der Haupttreiber für die Überschreitung von 5 der 9 #planetaryboundaries.

Und es macht rund 30% der weltweiten Treibhausgasemissionen aus.

Zugleich fehlt es Milliarden Menschen immer noch an gesunder #Ernährung.

Die 2025 Eatfoundation Lancet Commission präsentiert mit Beiträgen von #PIK die bisher umfassendste wissenschaftliche Analyse globaler Lebensmittelsysteme.

Die Ergebnisse zeigen, dass die Umstellung auf die #PlanetareHealth Diät bis zu 15 Millionen vorzeitige Todesfälle pro Jahr verhindern und die mit Lebensmitteln verbundenen #Emissionen um mehr als die Hälfte senken könnte.

The Planetary Health check has now diagnosed ocean acidification to be outside the safe operating space:
planetaryhealthcheck.org
PIK press release:
pik-potsdam.de/en/news/latest-

Short article quotes one of the researchers, Levke Caesar, with "I am afraid. This really scares me." theguardian.com/environment/20

I have questions.
For all of the previous 200 million years, CO2 was at a stable 1000ppm. Far higher than our goal-apparent of 600ppm, see picture of temperature and CO2 evolution after Judd, Tierney et al 2024 science.org/doi/abs/10.1126/sc

If those little snails from the PIK press release are already negatively affected from today's 430ppm, does that mean, their DNA only evolved during the last 2-3 million years, and rather suddenly, once CO2 dropped below this magical threshold?

Note also how CO2=ocean acidification never caused an extinction, only temperature did.
Surely, if the dying of the little critters were a precursor for an impending marine extinction event, it would have happened before? From 350 to 300 million years ago for example. Ample time for low-acidity-DNA like snails to evolve, and go extinct again when CO2 rose.

Whales have been around for 54mio years, in very high-CO2 times as well. What did they eat if snails weren't on the menu [of their prey]?
What did sharks eat at 1000ppm? They are truly old beings, 350 million years and more.
#PlanetaryBoundaries #climateChange #OceanAcidification #marinelife

Line chart of 485 million years of global temperature °C and CO2 concentration ppm. Also shown are 5 extinction events.
All of which, or at least 4 of them, the sharks survived.
Pre-industrial 280ppm CO2 is a very new invention for the planetary system. The longest near-constant stretch is at 1000ppm, lasting from 50 million years ago all the way back to 250mio years ago. Before 250mio years ago, CO2 wobbled around a lot more, going as high as 2000ppm and as low as 280ppm.
Extinction events are timed by temperature excursions which don't coincide with CO2 peaks or lows.
65mio years ago, the great dinosaur extinction from the meteor impact in Yucatan and temperature drop or shading of the sun.
200mio years ago, a rise by 5°C caused another extinction event.
Another was 250mio years ago due to a rise by 12°C.
370mio years ago, maybe as result of a preceding, slow rise by 8°C, but the chart is not clear in this case.
440mio years ago, an extinction event occurred from a temperature drop of 20°C.

To state the obvious: I am not saying it were possible to just replace fossil energy 1:1 with a renewable system and be done with it.
Like Nate says: climate is only 1 side of the cube. And the cube's other sides, ie the other #PlanetaryBoundaries , demand that we shrink today's global resource use, which of course impacts energy need.
And since the majority of today's global resource use is gobbled up by our societies, leaving but scraps for emerging and developing societies, it's a basic fact that our resource use has to cut to 1/4.
Today.

In this context, I like what Nate says about inequality vs communist equality, or Walrus equality😁 , and left authoritarianism.
Myths #4 and #3 respectively.
I too think that near-100% equality isn't realistic and also not really advisable to strife for as an ideal.

Yes, I want itemised rations for the transition time. But individuals should have freedom to either use their rations or exchange them on the black market for other stuff they want more. Like me, I wouldn't want a new winter coat every 5 years or whatever coat rhythm the rationing system allows.
So I'd trade my coat ration for, dunno, for cinnamon and cumin. Or for a hand-knitted sheeps wool pullover with a really cool pattern.

Ach, I'm rambling. Sorry. Good morning!

The planetary boundary Aerosol Load isn't breeched yet.

But Fredi Otto's report chapter attributes dire fallout: "in regions like Asia, where aerosol pollution
remains elevated, aerosols likely contribute to cyclone intensity alongside climate change."

planetaryhealthcheck.org

I wonder whether SO2 reduction in shipping fuel #IMO2020 has lessened the intensification of cyclones – despite ongoing pollution from coal power plants..

And also: if tropical storm strength gets elevated by aerosol load – 
is that then also the cause for lower wind speeds over the North Atlantic in 2023 which Rahmstorf and Matt England isolated as the major reason for the bananas?
