Children from East Africa, where heat waves and floods have shuttered schools in recent months, are pushing for world leaders to protect their education- and their future - at the United Nations COP29 climate summit in Azerbaijan.
Siama, 17, from South Sudan, missed two weeks of school in April when temperatures surged to 45 degrees Celsius.
Our country is a developing country so we do not have climate-resilient buildings and do not have ACs in school, she says.
More than 40 million children were kept out of classrooms this year, from Asia to Africa, due to extreme heat, which scientists say has been made worse and more frequent by climate change.
Naomi, 14, also struggled with South Sudans school closures.
