We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction, unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms, floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing. In early 2025, the World Meteorological Organization reported that 2024 was the hottest year on record (WMO 2025a). This was likely hotter than the peak of the last interglacial, roughly 125,000 years ago (Gulev et al. 2021, Kaufman and McKay 2022). Rising levels of greenhouse gases remain the driving force behind this escalation. These recent developments emphasize the extreme insufficiency of global efforts to reduce greenhouse gas emissions and mark the beginning of a grim new chapter for life on Earth.

Today, Nate is joined by Luke Kemp, a researcher whose work is focused on existential risks (or X-risks), which encompass threats of human extinction, societal collapse, and dystopian futures. How can we begin to understand the likelihood and gravity of these ruinous events, and what kinds of responses from people and governments could further undermine social cohesion and resilience? What roles do human biases, hierarchical power structures, and the development of technologies, like artificial intelligence and geoengineering, play in X-risks? How can we collaborate across industries to protect our modern systems through effective risk management strategies? And in what ways do our institutions need to become more inclusive to better democratize decision-making processes, leading to safer futures for humanity?

01 August 2024 – Humanity is facing its greatest emergency, a crisis consisting of many, interlinked, catastrophic risks, the Roundtable on the Human Future has declared. At present humanity has no way to deal with such a crisis – and a global plan of action is urgently needed, it said.

This innovative and comprehensive collection of essays explores the biggest threats facing humanity in the 21st century; threats that cannot be contained or controlled and that have the potential to bring about human extinction and civilization collapse. Bringing together experts from many disciplines, it provides an accessible survey of what we know about these threats, how we can understand them better, and most importantly what can be done to manage them effectively.
