What happened

School in a hot world: What research is saying about children's health and learning Lisa Lock Scientific Editor Andrew Zinin Lead Editor Climate change is making southern Africa hotter.

Why it matters

While much attention has focused on climate impacts such as droughts, floods and food insecurity, another crisis is unfolding quietly inside classrooms.

Common ground

Research has shown that some schools are becoming dangerously hot places for children to develop, learn and play.
