As firefighters face unprecedented choices about which blazes to prioritise, a stark reality is emerging: the climate crisis is turning once-lush vegetation into tinder-dry fuel for wildfires that are spreading rapidly across Europe and beyond. Senior officers warn of 'operational collapse' as concurrent fires become more common and occur earlier in the year.
This month has seen deadly wildfires sweep across Western Europe, with France, Portugal, and Spain recording an unprecedented number of blazes for this time of year. France has experienced record areas of land scorched, while 13 fatalities have been reported in Spain. Even the UK, traditionally less prone to such widespread incidents, started the week with 19 separate wildfires, prompting experts to warn of a 'firewave' on a scale not seen before.
The issue extends beyond the sheer number of hectares burnt. While global trends show a decrease in total burnt land due to agricultural fragmentation in areas like the African savannah, the fires that do occur are often hotter, less predictable, and more numerous. Rising global temperatures, exacerbated by carbon pollution, dry out plants, allowing small fires to escalate rapidly into infernos that encroach upon previously safe areas, including forests, moorlands, and increasingly, urban parks and residential gardens.
Across the Atlantic, the impact is also severe. Smoke from over 100 fires burning in northern Ontario rendered Toronto the world's most polluted city earlier this week before drifting across the US border to affect New York. Far-reaching fumes from Canadian wildfires were linked to 82,000 premature deaths in 2023, including 33,000 in the US and 22,000 in Europe. The EU's Copernicus agency reported 'extremely poor' air quality warnings in areas such as New Jersey this week.
Authorities in countries like France are already dividing scarce resources to combat the extreme scenarios. Julien Marion, head of the civil protection agency, stated that French firefighters have tackled between 250 and 300 fires simultaneously over the past three weeks. In Spain, firefighters accustomed to managing a couple of blazes at a time are now struggling with the increased frequency and intensity. Recent wet winters and springs have allowed vegetation to flourish, providing more fuel when it dries out in the summer, alongside the abandonment of farmland that once served as natural firebreaks.
