collapse of the old society

I'm going to highlight this paragraph:

It's worth saying, too, as many headlines point out, that meeting our target temperature of +1.5°C means we still lose the Greenland and Antarctic ice sheets. We should hope for this target, even if it's all but impossible, because it's certainly better than the alternative. But, as I've made clear, I don't think it's gonna happen.

A billion people live in areas 40 ft or less above sea level, areas that will be flooded when - not if, WHEN - the Greenland and Antarctic ice sheets go. A billion climate refugees. That's not a "possibility". That's inevitable even in the best case scenario of 1.5 C. The most likely scenario - 3 to 4 C by 2100 - is exponentially worse.

Solarpunk is about radical hope. Plenty of the visions for a solarpunk future are unlikely or improbable. But none of those visions should be impossible.

A future where the seas don't rise? That's impossible.

A future where we slow the rising seas through both individual and collective action, prepare global civilization for the oncoming crisis with love, unity, and respect for every single person's basic humanity, and end capitalism? That's still worth fighting for.

Global public debt could increase to 100 percent of global gross domestic product by the end of the decade if current trends continue, according to projections in our latest Fiscal Monitor. The rising ratio of public debt to GDP reflects renewed economic pressures as well as the consequences of pandemic-related fiscal support, according to our report. This trend raises fresh concerns about long-term fiscal sustainability as many countries face rising budget challenges.

The Chart of the Week shows that about a third of countries, accounting for 80 percent of global GDP, have public debt that’s both higher than it was before the pandemic and rising at a faster pace. More than two-thirds of the 175 economies in our study now have heavier public debt burdens than before COVID spread in 2020.

Author is: Cities By Diana. There are some urbanism themes.

Video description:

We are in a recession. The indicators are everywhere. Bad vibes, rage bait, AI generated slop content filling our for you feeds. Some may debate whether or not we are actually in financial recession, but there’s more to this recession than economic indicators. We are in a romance recession, an empathy recession, a creativity recession, a sincerity recession, a friendship recession, a vibes recession.

There’s this feeling that you can’t say or do the things you used to without being censored, or worse being called CRINGE. Everyone around you is busy, stressed, overwhelmed or generally disengaged from life. The quality of everything has reduced - products break sooner, food tastes worse. Every app has enshittified and become flooded with advertisements and negativity. entry-level jobs requiring years of experience, multiple rounds of interviews that if you even get through it all you get a lowball offer.

Dating apps have killed the traditional ways to find love and romance, and those have enshittified to the point where they are unusable, any alternatives like meeting people in the real world now seem more difficult than ever with the loss of third spaces and car-centric design of cities in the west, places where people do gather requiting a substantial purchase simply to exist in public life. Any time you leave the house it feels like you spend a hundred dollars or more.

We’ve been told for the past couple of years that the economy is booming, unemployment is at an all time low, we have the entire sum of everything ever known in the palm of our hands.

Yet we are all tired, lonely, broke, afraid or unable to do anything. Comments sections online are full of arguments, even on morally or politically neutral topics. We misunderstand each other, often deliberately. Some of us spend more time talking to ChatGPT than we do our own friends and family members. We are the most comfortable, most technologically advanced and most well educated generation in human history - yet we are miserable, lonely and stuck in a recession deeper than just economic. We are in a recession of the heart and mind.

Tldr: 3-6 ft of sea level rise is inevitable, which will result in at least 230 million climate refugees fleeing coastal areas around the world. At this point the Greenland and West Antarctic ice sheets are almost guaranteed to collapse, which will result in 40 ft of sea level rise and more than a billion climate refugees. And the only thing cutting carbon admissions now will do is slow the rate at which the world warms and give these refugees more time to escape the coasts.

Slowing that rate is still worth doing. And there's still hope to limit the damage. But what a wonderful world we've bequeathed to our children, huh?

A mysterious, brown foam appeared on a beach an hour south of Adelaide. It was just the beginning of a toxic algal bloom that has now grown to thousands of square kilometres in size, killing precious sea life in its wake. Experts say it could be a sign of things to come.

The blame was placed on an “ongoing marine heatwave” which had seen water temperatures 2.5 degrees Celsius warmer than usual.

On Kangaroo Island, which reported its first fish kills in March, some beaches were so littered with dead sea life, the smell was overpowering.

In Limits to Growth, a '70s era tome lauded by both environmentalists and doomsday conspiracy theorists, MIT scientists made a number of predictions about population growth, food production, etc, using the data available at the time -- and were immediately lambasted by the media and politicians as being fear-mongering, since they hinted that collapse would likely come in the 2nd half of the 21st century. Recently, investment guy Joachim Klement revisited the predictions, adding data from this century. The results were... not great, with some indicating that we're living in the peak of human development like literally right this minute.

Acute global food insecurity rose for the sixth year in a row in 2024, according to the 2025 Global Report on Food Crises (GRFC), a collaborative effort coordinated by the Food Security Information Network.

The report shows that climate extremes, conflict, forced displacement and economic shocks continue to drive malnutrition and food insecurity around the world, with disastrous impacts on those living in many of the most vulnerable regions in the world.

Plenty of farmland to go around.

You’re helping nature — but nature also has ways to help you, make you more resilient, and relieve the stress caused by environmental destruction.

• Climate change is colliding with land use practices, deforestation and biodiversity loss to drive a rapidly growing threat of crop pests.
• Future warming of 2° Celsius (3.6° Fahrenheit) above preindustrial levels (likely by the 2040s or 2050s, according to current projections) could see substantial losses of staple crop yields for wheat (an estimated 46% loss), rice (19%) and maize (31%) due to pest infestations, according to a recent paper.
• Temperate regions are likely to see the greatest increases in crop pests as warming creates conditions for migrating subtropical species to establish themselves in previously unhabitable areas.
• The authors underline the need for more pest monitoring, diversification of farmland crops and biotechnological solutions to meet this growing threat.

Note that future warming is likely to be up to 50% greater than stated in this article.

The rhetoric of “hopium” is failing as ecological overshoot deepens. “Hopium”, a colloquial term that is a blend of the words “hope” and “opium” (as though it were a drug), represents a faith in technological and market-based solutions to address our multiple reinforcing crises, despite evidence to the contrary. We're living in the long defeat and we must own and confront it with courage.

Nearly three-quarters of everything on the average American plate is processed, packaged, shipped, stored, and/or sold under refrigeration. The United States already boasts an estimated 5.5 billion cubic feet of refrigerated space—a third polar region of sorts. Equal to what 244,444,444 domestic refrigerators (at 22.5 cubic feet on average) could hold. This is an almost unimaginably large volume: the tallest mountain on Earth, Everest, occupies only roughly two-thirds that amount of space from base to peak.

According to the most recent statistics from the Global Cold Chain Alliance, the world’s chilled and frozen warehouse space increased by nearly 20% between 2018 and 2020.

There are approximately 22.7 billion broiler chickens living out their five-to-seven-week spans on Earth at any moment, compared with just half a billion house sparrows or a quarter of a billion pigeons. Those chickens are also double the size and five times the weight of their preindustrial ancestors, giving them a combined mass that exceeds that of all other birds on Earth. The team of researchers behind these calculations used them to suggest that the layer of chicken bones currently piling up in landfills around the world is, in fact, an ideal marker of the Anthropocene.

Chickens may be a signal to future geologists, but environmental scientist Vaclav Smil suggests that cows might perform that role for aliens. Meat and dairy animals so vastly outweigh all other vertebrates that “if sapient extraterrestrial visitors could get an instant census of mammalian biomass on the Earth in order to judge the importance of organisms simply by their abundance, they would conclude that life on the third solar planet is dominated by cattle.” In aggregate, livestock make up 62% of all mammals on Earth; humans, at 34%, account for most of the rest. Everything else—dogs, cats, deer, rabbits, whales, elephants, bats, and even rats—only adds up to the remaining 4%.

Livestock takes up nearly 80% of global agricultural land; cattle ranching is responsible for the deforestation of an area more than double the size of California in the Amazonian rainforest alone.

Fish are notoriously hard to count, but according to the best estimates, their numbers have decreased by half over the past fifty years.

The staple crops of subsistence farmers — banana, breadfruit, potato, and so on — do not require refrigeration. What, then, could the problem be...

Tony Blair has called for the government to change course on climate, suggesting a strategy that limits fossil fuels in the short term or encourages people to limit consumption is “doomed to fail”.

In comments that have prompted a backlash within Labour, the former prime minister suggested the UK government should focus less on renewables and more on technological solutions such as carbon capture.

Blair said people were “being asked to make financial sacrifices and changes in lifestyle when they know that their impact on global emissions is minimal”. He said “any strategy based on either ‘phasing out’ fossil fuels in the short term or limiting consumption is a strategy doomed to fail”.

The paper itself, written by the TBI’s Lindy Fursman, said net zero policies were now “increasingly viewed as unaffordable, ineffective or politically toxic”.

The European Commission’s new plan to overhaul the EU’s main chemical regulation, REACH, risks undoing two decades of progress in protecting people and nature from toxic substances.

In the mid-1990s physicists Geoffrey West and Louis Bettencourt collaborated with biologists to study allometric scaling laws, where it is generally found that larger organisms are more efficient consumers of energy than smaller ones. After mathematically explaining these laws through fractal network effects, the researchers began applying them to the human built environment, particularly cities.

Certain environmentalists and sustainability advocates mistook the significance of these results, leading to decades of policy work and investments in urban growth that, West now admits, are doomed to fail.

The fact that so many, including the originators of the work, got this story wrong reflects the cultural blinders and techno-biases that typify most of us living in high energy modernity. Doing the opposite of our conditioned response to the overshoot predicament will likely lead to more favorable outcomes.

Please note that this article contains questionable arithmetic:

That brings the annual mean global concentration close to 430 ppm, about 40 percent more than the pre-industrial level, and enough to heat the planet by about 2.7 degrees Fahrenheit (1.5 degrees Celsius).

The actual figure from NOAA is 428.15 ppm (last updated 2025-04-14). If we use the more precise pre-industrial estimate of 278 ppm, then we get an increase of 54%, which is indeed "about 40%" if we round to the nearest multiple of 40%.

Climate models tend to underestimate the cooling effect of aerosol pollution, and the climate sensitivity is actually about 50% greater than previously thought, so a more realistic estimate of the warming caused by a doubling of carbon dioxide concentration over the pre-industrial level is 4.5°C. If we assume that the relationship is linear, this means that the current level of 428.15 ppm is "enough to heat the planet" by 4.5°C * 54% = 2.43°C, which is... more than 1.5°C.

Yes it has.
