South Sudan's Heat Wave Intensified by Climate Change, Study Reveals

A recent study highlights that climate change has made extreme heat waves in South Sudan ten times more likely, presenting dangers especially for vulnerable populations amid the country's historical challenges with conflict and food insecurity.

After a severe heat wave in February 2025, schools in the capital city of South Sudan, Juba, were forced to close for two weeks as students suffered from heat strokes. This incident marks the second closure in a year, underscoring the acute dangers posed by escalating temperatures. Research from World Weather Attribution asserts that climate change, primarily driven by emissions from wealthier nations, has made this wave of extreme heat at least ten times more likely, increasing temperatures by an estimated 2 degrees Celsius.

In late February, some areas of South Sudan reported temperatures exceeding 42 degrees Celsius (107 degrees Fahrenheit). The study utilized a mix of weather data, observations, and climate models to arrive at these findings, although it has yet to undergo peer review. Joyce Kimutai, a researcher with the Center for Environmental Policy at Imperial College London, noted that Africa contributes only a small fraction of global greenhouse gas emissions but suffers immensely from the consequences of climate change.

Extreme heat is becoming one of the deadliest forms of weather, with its frequency and severity on the rise globally. However, mortality metrics can significantly vary, making it difficult to accurately assess the death toll from heat waves soon after occurrences. Vulnerable groups, particularly children, the elderly, and pregnant women, face the highest risks during these extreme heat events.

Currently, the Eastern African region, which includes parts of Kenya and Uganda, is under prolonged heat conditions, compelling health officials to advise residents to stay indoors and hydrate. This directive presents considerable challenges in nations where outdoor labor is commonplace, electricity supply is unreliable, accessible clean water is limited, and housing lacks adequate cooling mechanisms.
