What happened

Climate change is making southern Africa hotter.

Why it matters

While much attention has focused on climate impacts like 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.

Claim 1: “One of our studies traced relationships between classroom temperature and absenteeism, which increased at temperatures over 25°C.”
SINGLE SOURCE
While web search results discuss the general impact of high temperatures (above 27°C) on cognitive function, there is no specific independent corroboration for the exact 25°C threshold for absenteeism mentioned in the claim. The provided Wikipedia results are irrelevant.
