For years, climate scientists have warned us of rising temperatures, extreme weather, and ecological breakdown. Now, the very people who calculate financial risk—actuaries—are sounding the alarm. Their latest report projects a 50% collapse in global GDP within decades. That’s not a recession. That’s economic devastation on a scale we’ve never seen.

Collapse isn’t loud. It’s not a Hollywood explosion, not a sudden black hole swallowing the United States overnight. There’s no singular moment when the world collectively gasps and realizes everything has come undone. Instead, collapse is a slow, grinding process — insidious, creeping, and patient.

Thoughts on the Collapse of Civilization

The CIO of Goldman Sachs has said that in the next year, companies at the forefront will begin to use AI agents as if they were employees — as team members with tasks to do.

The abrupt loss of many species from a system is generally attributed to a breakdown in ecological functioning. As species are sequentially knocked out, the whole community becomes unstable, and it all comes crashing down. Another mechanism that may be at play. My colleagues and I argue that despite the fact life on Earth displays such great variety, many species that live together appear to share remarkably similar thermal limits. That is to say, individuals of different species can tolerate temperatures up to similar points.

The year 2024 wasn’t just another chapter in the unfolding climate saga; it felt like the plot twist no one wanted to believe. For decades, climate scientists warned of ifs — if we pass this tipping…

L'apocalypse serait-elle devenue un sujet d'étude aussi banal que la photosynthèse ou les fractales ? Ces deux dernières décennies, le vocabulaire de la fin du monde s’est métamorphosé en un champ lexical scientifique florissant. Des concepts comme l’anthropocène ou les planetary boundaries ont proliféré dans les revues académiques. Des notions plus anciennes comme la polycrise d’Edgar Morin et le collapse ont resurgi récemment, transcendant les frontières disciplinaires, tandis que les cascading failures, les wicked problems ou les compound risks sont devenus incontournables dans l’analyse des risques.

I mapped out a likely scenario, based on a synthesis of a variety of estimates combined with a dose of interpretation. While I can't predict the future, if we continue business as usual we'll soon witness compounding destruction of our infrastructure, economy and agricultural systems. A reasonable estimate suggests cascading civilizational and social collapses by mid-century - just 25 years from now.

The climate and ecological crisis poses an unprecedented challenge, with scientists playing a critical role in how society understands and responds. This study examined how 27 environmentally concerned scientists from 11 countries construct the future in the context of climate change, applying a critical discursive psychology analysis. The degree to which the future is constructed as predetermined or transformable impacts both the urgency and scope of proposed actions. ...
