Climate change, dam collapses and water-borne disease: devastation in Libya caused by Storm Daniel

On September 10th of 2023, Storm Daniel made landfall in northeastern Libya, bringing torrential levels of rain and strong winds (Figure 1). This onslaught of rain caused two big dams in the region to break – the Abu Mansour dam and the Derna dam, 75 metres and 45 metres tall respectively.
