Climate Change Drives Over One Billion Food Crises
9.1
A quantitative ecologist published new research in 2025 using an AI model to project climate-driven food insecurity through 2100. The model estimates that under high-emission scenarios over 1.16 billion people, including more than 600 million children, will face at least one severe food crisis, while aggressive decarbonisation could spare roughly 780 million people.
Key Points
- 1Projects over 1.16 billion people exposed to at least one severe food crisis by 2100
- 2Highlights Africa and Asia hotspots; central Africa faces strong demographic-driven exposure increases
- 3Implies aggressive decarbonisation and sustainable development could spare roughly 780 million people
Scoring Rationale
High novelty and global scope drive the score, tempered by single-study evidence and projection uncertainties.
