Europe’s Wildfires Unearth Deadly Legacy of World War Ordnance

Unexploded Munitions Ignited by Summer Fires
Wildfires across France, Belgium, Germany and the Netherlands this summer have detonated rusted bombs and mines from the World Wars. In Limburg, a bomb-disposal team responded to a forest near a 1944 combat site. Similar incidents were reported in the High Fens of eastern Belgium and in a forest outside Bordeaux, where a cache of presumed World-II ammunition was uncovered.
Historical Legacy and Climate Drivers
The regions sit atop landscapes littered with decades-old ordnance. In the first four years after Germany’s 1945 surrender, unexploded weapons in the High Fens killed six civilians, according to local historian Bernard Collard of the Truschbaum Museum. Belgium’s Explosive Ordnance Disposal service now handles thousands of calls annually, disposing of hundreds of tonnes of munitions.
Researchers link the surge in detonations to climate change. A World Weather Attribution study published in July identified drought, low humidity and strong winds as creating optimal conditions for both wildfires and the ignition of buried explosives.
Key Actors Responding
- Sarah Njeri – peace-and-conflict scholar, SOAS; highlights climate-driven exposure of ordnance.
- Governor Hervé Jamar – Liège province; reported sporadic detonations and assured fire-crew safety.
- Jonas Tepe – spokesperson for North Rhine-Westphalia; warned heat can trigger explosives.
- Bernard Collard – historian and museum director; provides context and assists de-mining squads.
Scale of the Threat
- Belgium’s EOD service processes over 3,000 weekly requests, handling 200–250 tonnes of munitions each year.
- Fires this summer have burned more than 1.4 million acres across Western Europe.
- In the High Fens, the blaze has scorched roughly 3,000 hectares, the largest Belgian wildfire in decades.
Official Statements & Responses
Regional authorities have adapted protocols for hidden weapons. German spokesperson Jonas Tepe reiterated that elevated temperatures increase the risk of accidental detonations, urging vigilance among firefighting units. Belgian de-mining squads, working with historians, continue systematic scanning of former battlefields using metal detectors to locate and neutralize ordnance before it can be ignited.
Verbatim Quotes
- “Our results indicate there could be widespread increases in burned area even under comparatively low warming of around 1.8°C. But if we emit more, and global temperatures rise by roughly 3.6°C, we see fires become much more prevalent, especially around the Mediterranean and across much of Western and Central Europe, including areas that to date have not experienced many fires,” — Maik Billing, lead author.
- “Climate change is driving fire activity across Europe as hot, dry and windy conditions become more severe,” — Maik Billing.
Why It Matters
The convergence of climate-driven wildfires and century-old unexploded ordnance creates a compound hazard for responders and nearby communities. Explosions can endanger firefighters, damage infrastructure and impede containment, while buried munitions add a lethal, unpredictable element to an already volatile fire environment.
Conflicting Reports & Gaps
While multiple sources confirm detonations in France, Belgium, Germany and the Netherlands, precise counts of explosions and the total weight of ordnance uncovered remain unspecified, leaving a gap in understanding the full scale of the risk.
What’s Next
Authorities plan to increase joint bomb-disposal operations during fire season and to integrate climate-risk assessments into emergency-response planning. Researchers will continue monitoring the link between rising temperatures and ordnance exposure.
