As extreme heat and wildfires sweep across parts of Europe, the receding vegetation and scorched earth have revealed a dangerous legacy from the 20th century. Decades after the conclusion of World War I and World War II, thousands of unexploded bombs, mines, and artillery shells remain buried in European soil. The current wildfire season has cleared away the brush and topsoil that previously concealed these munitions, creating new hazards for emergency responders and civilians.

Experts note that the heat from wildfires can potentially destabilize the chemical components of old explosives, making them more volatile and prone to detonation. In regions like the forests of Germany and parts of France, where heavy fighting occurred during the wars, local authorities have had to adjust firefighting strategies. In some instances, fire crews are restricted from entering certain areas until bomb disposal experts can clear the ground, as the risk of accidental detonation is considered high.

While the phenomenon of finding "iron harvests" is not new to farmers or construction workers in these regions, the scale of the wildfires has brought the issue to the forefront of public safety concerns. The situation highlights the long-term environmental and security consequences of past conflicts, which continue to manifest as climate-related disasters alter the landscape. Governments are currently assessing how to manage these areas safely while the fire risk remains elevated.
