European wildfires expose and detonate buried WWI and WWII bombs; 'climate change is now doing the work of unburying' them, says scholar

European wildfires have unearthed unexploded World War I and II ordnance, posing new dangers as climate change exacerbates conditions. Scholars warn that rising temperatures and droughts are reactivating buried munitions, leading to sporadic explosions in France, Belgium, Germany, and the Netherlands, threatening firefighting efforts.

European wildfires this summer have revealed a hidden danger: unexploded ordnance from World War I and II. As wildfires rage across the continent, climate change is exacerbating conditions that unearth these munitions, leading to sporadic explosions and posing risks to firefighting efforts.2369

Fires have devastated vast areas in western Europe, with scorching temperatures and droughts creating ideal conditions for wildfires. Sarah Njeri, a peace and conflict scholar, noted, “Climate change is now doing the work of unburying and reactivating what was previously stable.” This has resulted in explosions reported in France, Germany, Belgium, and the Netherlands.8

In southwestern France, a fire near Bordeaux uncovered a cache of World War II-era ammunition. In eastern Belgium's province of Liège, local governor Hervé Jamar reported that emergency services are adapting to the presence of munitions, with “a few sporadic detonations” heard recently. The area, known for its dense peat-bog forest, was a battleground during the Battle of the Bulge.4

The wildfires have also churned up military vehicles and weapons, with Christina Greene from the University of Arizona stating, “the legacy of war keeps creeping up” due to climate change. The situation underscores that Europe’s “climatic luck” is running out, as the combination of heavy rains and subsequent drought has created a perilous environment for both the land and its inhabitants.

Local historian Bernard Collard emphasized the unpredictability of the situation, stating, “you are not sure where the explosives are.” His experiences highlight the ongoing risks posed by these buried remnants of conflict, as the wildfires continue to expose them.

Key Insight
“In Liège, Governor Hervé Jamar reported 'a few sporadic detonations' and said emergency services are adapting, while a Bordeaux fire revealed around 400 shells, including German and French mortar and anti-tank rounds. Historian Bernard Collard, who scans former battlefields, warns 'you are not sure where the explosives are.'”
