A new and ominous term has emerged in the vocabulary of firefighters battling a massive wildfire in southwestern France: pyrocumulonimbus. This fire-generated thunderstorm can create unpredictable winds, making containment and forecasting far more difficult. Known in North America and Australia, firefighters believe this is the first such phenomenon in France, occurring in the Bordeaux region as the country suffers through its third major heatwave of the summer and braces for a fourth.
Statistics show deepening devastation
The ongoing fires in France and Spain reveal a story of increasing destruction and human suffering. A far larger area of French land has already burned this year compared with the 30,000 hectares during the whole of 2025, while 220,000 people have been evacuated from their homes in the Gironde. In Spain, the environment ministry has reported that over 170,000 hectares have been affected, compared with 29,000 last year, with more than 100,000 people forced to flee.
As climate scientists have long warned, Europe's wildfires are worsening in intensity, scale, and duration as the planet heats up. Spanish Prime Minister Pedro Sánchez attributed the current crisis to the climate emergency, noting the obvious. However, he has been among the few leaders arguing for an accelerated European Union green transition. Far too many others appear content to fiddle while the continent burns, whether on funding adaptation or driving the macro changes needed to slow global heating.
Policy contradictions amid heat
In June, with notably poor timing, Emmanuel Macron's government sought savings by announcing steep cuts to a Green Fund designed to help local authorities tackle climate and environmental challenges. Across Europe, amid persistent low growth and fallout from Donald Trump's war on Iran, a false dichotomy is increasingly drawn between green ambition and competitiveness. This month, under pressure from countries like Giorgia Meloni's Italy, the European Commission unveiled proposals to weaken the EU's emissions trading system, its flagship climate policy. If adopted, heavy industry would receive free polluting permits for longer and at lower cost.
Calls to dilute green measures often assert that Europe needs a more pragmatic approach during geopolitical uncertainty and aggressive economic competition. This argument is doubly wrong: the faster the EU moves toward net zero, the better it will consolidate its position in future global markets. More fundamentally, as this summer's wildfires vividly illustrate, the notion that climate measures are optional add-ons appropriate only in good times is wildly at odds with developing reality.
Fourth heatwave looms
As a fourth heatwave hits Europe, temperatures in southwestern France are predicted to reach 40°C on Wednesday. According to a recent study, if the warming rate of the last decade continues, the 1.5°C limit set by the Paris Agreement will be redundant by 2030. Yet far from catching up with the pace of change, too many governments and leaders are putting their foot on the policy brake. That is not realism; it is a dereliction of duty.
