Climate change has made extreme rainfall in West Africa five times more likely than in the late 19th century, scientists said Thursday. The finding follows regional floods that killed nearly 100 people last month.
The Study
A rapid attribution study by the World Weather Attribution network found that climate change increased the likelihood of extreme rainfall in West Africa by a factor of five compared to pre-industrial levels. The analysis focused on the Sahel region, where floods in August killed at least 97 people in Niger, Nigeria, and Chad. Scientists used climate models to compare current conditions with a counterfactual world without human-caused warming.
Regional Impact
The floods displaced over 200,000 people across the three countries, according to the UN Office for the Coordination of Humanitarian Affairs. In Niger alone, 53 deaths were reported, while Nigeria recorded 28 fatalities. The extreme rainfall also damaged infrastructure, including roads and bridges, hampering relief efforts.
