Europe’s Wildfire Frontier Expands Northward Beyond Traditional Hotspots

For decades, Europe’s wildfire season was largely associated with the Mediterranean region, including Spain, Portugal, Greece, and southern Italy. However, the summer of 2026 is rapidly challenging that long-held assumption as fires burn through forests, peatlands, and nature reserves in northern and western Europe. Regions historically viewed as low-risk for large wildfires are now experiencing unprecedented blazes. Scientists stress that this expansion is no longer an isolated weather anomaly, but a clear sign that climate change is actively reshaping the continent's fire geography.

Unprecedented Blazes Strike Northern and Western Europe

Belgium has experienced its largest recorded wildfire in the High Fens nature reserve, where flames spread across thousands of hectares of peatland near the German border. Meanwhile, in southwestern France, catastrophic fires around Bordeaux forced more than 220,000 people to evacuate, making it one of the country’s most destructive wildfire disasters in modern history. Similar fires have also affected parts of Croatia, Greece, Portugal, and even areas farther north than traditional fire zones, such as the Scottish Highlands.

Scientists warn that these fires are no longer isolated weather anomalies, but a signal that climate change is reshaping Europe's fire geography.

Europe is currently warming faster than any other continent. According to the European Commission’s Joint Research Centre, drought has gripped large parts of Europe since spring, leaving forests and grasslands highly combustible.

• More than 600,000 hectares of land have already burned across Europe during the 2026 season.

• Prolonged drought, record-breaking temperatures, and strong winds have created combustible conditions.

• Forecasts continue to predict hotter and drier weather through late summer.

Land Management Decisions Fuel Complex Fire Behaviours

The expanding wildfire map is closely linked to decades of historical land management decisions. In southwestern France, many forests are dominated by highly flammable pine plantations established during the nineteenth century. During this summer’s extreme heat, these forests acted as immediate fuel for rapidly spreading fires. The intense heat generated enormous smoke plumes and even fire-induced thunderclouds, a rare phenomenon known as a pyrocumulonimbus cloud.

Belgium’s High Fens presents a vastly different ecological challenge. Its peat-rich soil allows fires to burn underground for weeks or even months, making them extraordinarily difficult to extinguish. While rain may temporarily reduce surface flames, smouldering peat can easily reignite when temperatures rise again. Firefighters across Europe are increasingly forced to confront these complex fire behaviours in ecosystems that were never previously considered major wildfire landscapes.

A Broader Security Threat to the European Continent

Researchers argue that Europe’s wildfire crisis has expanded far beyond an environmental issue into a major public health, economic, and security challenge. Smoke from large fires has travelled hundreds of kilometres across borders, while widespread drought continues to disrupt agriculture, river transport, and energy production across several nations.

• Even if global warming is limited to around 1.8°C, European wildfires could increase by nearly 39 percent by late century.

• Under higher-emissions scenarios, the total burned area across the continent could nearly triple.

• Emergency systems, food security, and critical infrastructure face mounting pressure.

Countries that once focused primarily on winter storms and floods are now forced to invest heavily in wildfire aircraft, cross-border emergency cooperation, and long-term adaptation strategies. However, experts caution that emergency response alone cannot eliminate the growing threat without deeper cuts in greenhouse gas emissions.
