limits
2025
J’ai l’habitude de voir les écologistes et les futurologues parler des limites de la croissance (« The Limits to Growth »). Je suis moins habitué à voir des spécialistes de l’investissement mentionner des recherches liées aux limites de la croissance. C’est pourtant ce qu’a fait récemment Joachim Klement dans sa lettre d’information quotidienne. Bien entendu, quiconque écrit sur les limites de la croissance doit d’abord procéder à toutes les vérifications d’usage. En effet, la combinaison des mots « limites » et « croissance » dans le titre a suscité un grand nombre de réactions critiques, allant de la déformation pure et simple de l’ouvrage à l’incompréhension du modèle de dynamique des systèmes qui le sous-tend.
I’m used to environmentalists and futurists writing about The Limits to Growth. I’m less used to seeing investment writers mention research that’s linked to The Limits of Growth. But that’s what Joachim Klement did in his daily newsletter recently.

But that’s what Joachim Klement did in his daily newsletter recently. Of course, anyone who writes about Limits of Growth has to do all the usual disclaimers first. This is because the combination of the words “limits” and “growth” in the title produced a lot of critical responses, on a range from straight-up hatchet jobs which misrepresented the book, to people who didn’t appear to understand the systems dynamics model that sat behind it.
Millions of Americans rely on drinking water systems that have detected these forever chemicals at levels above the now-abandoned limits.
For hundreds of millions of people living in India and Pakistan the early arrival of summer heatwaves has become a terrifying reality that’s testing survivability limits and putting enormous strain on energy supplies, vital crops and livelihoods. Both countries experience heatwaves during the summer months of May and June, but this year’s heatwave season has arrived sooner than usual and is predicted to last longer too. Temperatures are expected to climb to dangerous levels in both countries this week.
Before you read this, a word of caution. You may want to prepare yourself a stiff drink and sit down before you read the following. I think most people who read this will at some point in their life heard about the Club of Rome’s Limit to Growth publication from the 1970s. Back then, the Club of Rome asked the MIT to produce a series of forecasts for the world’s industrial and services output, food production, and pollution levels to the year 2100. Almost from the get-go, these forecasts were derided as scaremongering and flat out wrong. But were they really?
Morgan Stanley, JPMorgan and an international banking group have quietly concluded that climate change will likely exceed the Paris Agreement’s 2 degree goal.Top Wall Street institutions are preparing for a severe future of global warming that blows past the temperature limits agreed to by more than 190 nations a decade ago, industry documents show.
Recent projections suggest that large geographical areas will soon experience heat and humidity exceeding limits for human thermoregulation. The survivability limits modeled in that research were based on laboratory studies suggesting that humans cannot effectively thermoregulate in wet bulb temperatures (Twb) above 26 to 31 °C, values considerably lower than the widely publicized theoretical threshold of 35 °C. The newly proposed empirical limits were derived from the Twb corresponding to the core temperature inflection point in participants exposed to stepped increases in air temperature or relative humidity in a climate-controlled chamber. Despite the increasing use of these thermal-step protocols, their validity has not been established. We used a humidity-step protocol to estimate the Twb threshold for core temperature inflection in 12 volunteers.
Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.
💡 Is our obsession with economic growth leading us to collapse? Economist and research Gaya Herrington joins us to discuss why GDP is a flawed metric, how degrowth can lead to a thriving well-being economy, and why businesses must prioritize resilience over efficiency. Tune in for a critical conversation on reshaping our economic future.
