Global Catastrophic Risks 2026

This report presents the Global Challenges Foundation’s assessment of the most pressing catastrophic risks facing humanity today. It identifies five key threats: catastrophic climate change, ecological collapse, weapons of mass destruction, the use of AI in military decision-making, and near-Earth asteroids. The report highlights how these risks are becoming increasingly interconnected, accelerating and reinforcing one another across environmental, technological, and security domains. It calls for inclusive, proactive, and adaptive global governance reforms to reduce their likelihood and impact.
