Climate change is a major driver of food crises
Socioeconomic choices determine how deadly it becomes

Under pessimistic pathways, >230 million newborns could face a food crisis within their first year of life. These are not marginal differences—they are orders of magnitude apart.

The burden is highly unequal. Most future food crises are projected in Africa and Asia, with children under 5 making up the majority of first-time exposures.

When combined with population & poverty projections, model's projections depict a stark future:
➤ SSP3–4 (conflict & inequality):>1.1 billion people exposed by 2100
➤ SSP1-2(sustainability & middle-of-the-road): exposure more than halved

I developed a machine learning model using temperature & precipitation data to predict the onset of novel, severe food crises based, the model captures both direct and indirect climate effects on food security—without relying on complex socioeconomic inputs.
