Homeland Security Operational Analysis Center – Global Catastrophic Risk Assessment

The "Global Catastrophic Risk Assessment" report, published by the Homeland Security Operational Analysis Center, provides a comprehensive analysis of existential threats that could significantly disrupt human civilization. The report examines six primary hazards: artificial intelligence, asteroid and comet impacts, sudden and severe climate change, nuclear war, severe pandemics (both natural and synthetic), and supervolcanoes. It assesses the likelihood and potential consequences of each threat, identifies contributing factors and associated uncertainties, and evaluates whether these risks are expected to change over the next decade. The study highlights that global catastrophic risks have been increasing in recent years and are likely to continue rising, particularly due to human activities. For instance, risks associated with artificial intelligence, climate change, nuclear war, and pandemics are projected to escalate, while those from supervolcanoes and asteroid impacts may remain constant or decrease. The report emphasizes the importance of developing mitigation strategies, such as advancing technological safeguards, enhancing global governance and coordination, and promoting sustainable development, to manage and reduce these risks effectively.
