Europe’s Wildfires Unearth Deadly World-War Ordnance

The Immediate Threat: Fires Triggering Explosives
During the summer of 2024, wildfires in France, Belgium, Germany and the Netherlands have ignited or exposed rusted bombs and mines from the First and Second World Wars. In the Dutch province of Limburg, a bomb-disposal team was dispatched to a forest near a 1944 combat site. Similar incidents have been reported in the High Fens of eastern Belgium, where “a few sporadic detonations” were heard, and in a forest outside Bordeaux, where a cache of presumed World-II ammunition was uncovered. The heat can ignite the explosives directly, while flames also burn away vegetation that had concealed the weapons for decades.
Background: Legacy Munitions Meet a Changing Climate
Unexploded ordnance (UXO) has been a persistent hazard in Europe since the two world wars. In the first four years after Germany’s 1945 surrender, six civilians were killed by leftover munitions in the High Fens, according to local historian Bernard Collard of the Truschbaum Museum near the Belgian-German border. Climate scientists note that historically “steady temperatures and predictable rainfall” kept many of these weapons dormant.
On-the-Ground Reports
Firefighters in Belgium have been photographed handling rusted bombs while containing the blaze. In the High Fens, they recovered mortar shells, machine-guns, helmets and a human skeleton. In Slovakia, police pulled two naval mines from the Danube after the river fell, and Hungarian authorities closed Budapest’s Margaret Bridge when a World-II bomb emerged from receding water.
Official Statements & Responses
Governor Hervé Jamar of Belgium’s Liège province confirmed the recent detonations, adding that emergency services are adapting their tactics but that no fire crews were in immediate danger. Jonas Tepe, spokesperson for North Rhine-Westphalia, emphasized that heat can trigger explosives, increasing the risk to responders. The Belgian Ministry of Defence noted that it receives weekly requests for UXO assistance in the region, though it does not label the area a “hotspot.”
Data & Statistics
- Wildfires this summer have burned more than 6,000 sq km of forest across Europe, with an estimated economic cost of €15 billion (? $17.5 billion).
- In the High Fens, roughly 3,000 ha (about 30 km²) of vegetation have been scorched, marking the largest Belgian wildfire in decades.
- Belgium’s Explosive Ordnance Disposal and Destruction Service reports over 3,000 calls annually and disposes of 200–250 tonnes of munitions each year.
- A study by the Potsdam Institute for Climate Impact Research projects that, even with strong climate action, 39 % more land could be burning annually by the end of the century, and the total burned area could triple under current emission trajectories.
Why It Matters
The convergence of climate-driven wildfires and historic UXO creates a dual hazard: emergency crews face both fire and explosive threats, and the exposure of buried weapons revives painful wartime legacies for local communities. The incidents illustrate how climate change can amplify existing safety risks, underscoring the need for integrated fire-prevention strategies and accelerated climate mitigation.
Conflicting Reports & Gaps
The Belgian Ministry of Defence does not consider the High Fens a UXO “hotspot,” yet the Explosive Ordnance Disposal service handles thousands of calls in the same region each year. No comprehensive tally of detonations linked directly to wildfire heat has been published, leaving the true scale of the explosive risk uncertain.
Verbatim Quotes
- “Climate change could create conditions so extreme that we reach the limits of what is still feasible in preventing and fighting fires once they grow beyond a certain size,” — Kirsten Thonicke, PIK.
