A scorching summer that dried up rivers and killed tens of thousands across the European Union from Portugal to Hungary has shown that the bloc needs to develop new tools to meet a worsening climate, European Commission President Ursula von der Leyen said Wednesday.

She said that this instability led her to propose a new European Heatwave Plan as well as a future European firefighting fleet of aeroplanes. Currently, the EU operates a small fleet itself but coordinates a network of aircraft, water trucks and volunteers that move across the 27-nation bloc as fires ignite.
