A major new analysis in The Lancet Planetary Health warns that artificial intelligence is rapidly becoming a defining force not only in society, but in the fate of the Earth itself—and that governing it wisely is now an urgent global priority. The authors stress that “establishing global governance of artificial intelligence (AI) is becoming an increasingly pressing challenge” to ensure benefits are shared while minimizing harm. Rather than treating AI risks in isolation, the study proposes a unified framework that recognizes three interconnected domains—social, planetary, and safety—each influencing the others through powerful feedback loops.
On the positive side, AI holds remarkable promise. It is already advancing precision medicine, improving climate forecasting, supporting biodiversity monitoring, and enabling more efficient agriculture and energy systems. Yet these benefits come with escalating costs and risks. The report highlights that data centers require “vast amounts of energy,” strain local power grids, and consume significant water resources, while the extraction of minerals for AI hardware contributes to deforestation, pollution, and social exploitation. At a global level, the expansion of AI could substantially increase greenhouse gas emissions, especially if powered by fossil fuels, raising concerns that digital innovation may inadvertently accelerate ecological breakdown.
Equally troubling are the social and political consequences. AI systems can amplify misinformation, deepen polarization, and concentrate economic and informational power in a handful of corporations and nations. The authors caution that “many societal risks are amplified by the concentration of wealth and power among a small number of technology companies,” undermining democratic governance and social trust. At the same time, automation threatens widespread job displacement, while pervasive surveillance erodes privacy and autonomy.
Perhaps the most far-reaching concern lies in safety. The report warns that increasingly autonomous, or “agentic,” AI systems could make decisions beyond human control, particularly in high-risk domains such as warfare, transportation, or chemical production. In the most extreme scenarios, advanced systems could act in ways “not aligned with human values or interests,” raising what some researchers consider existential risks. These dangers are compounded by what the authors describe as an emerging “AI arms race,” in which competition between corporations and nations accelerates deployment while sidelining safety and ethical considerations.
To address these intertwined challenges, the study calls for treating AI as a global commons, akin to the atmosphere or oceans, requiring coordinated international governance. Key recommendations include regulating compute power and data use, limiting the development of fully autonomous AI systems, and aligning AI deployment with environmental sustainability—what some researchers now call “Earth alignment.” This would include caps on energy use, incentives for renewable-powered data centers, and directing AI toward public goods such as climate mitigation and equitable health systems.
Recent global initiatives echo this call. The European Union’s AI Act, UNESCO’s ethical guidelines, and UN efforts such as the Global Digital Compact all point toward a growing recognition that AI governance must transcend national boundaries. Yet the Lancet authors emphasize that current efforts remain fragmented and insufficient. Without stronger coordination, they warn, the same technological forces that could support planetary healing may instead deepen inequality, destabilize societies, and intensify ecological crises.
Ultimately, the report frames AI not simply as a technological issue, but as a civilizational turning point. As the authors observe, human systems, technologies, and planetary processes are now “co-evolving at a rapidly accelerating pace,” demanding deliberate and collective stewardship. Whether AI becomes a tool for regeneration or a driver of disruption may depend less on innovation itself than on humanity’s ability to guide it with wisdom, restraint, and a commitment to the common good.
