Extreme heat, natural disasters, food insecurity: the impacts of climate change are already clearly visible and increasingly felt in many parts of the world. While the consequences for physical health are becoming better understood, the effects on mental health remain insufficiently researched and receive little attention in climate, health and development policy. Against this backdrop, the Leopoldina and the Academy of Science of South Africa (ASSAf) will host a workshop in South Africa from 8 to 10 September 2026. Early-career researchers from Germany, Austria, Switzerland and South Africa are invited to apply by Friday, 3 April 2026.
