Giant Wildfires Sweep Across the Globe
Since the beginning of July 2026, massive wildfires have been multiplying in several regions of the world. Southern Europe, North Africa, and North America are facing faster, more difficult to control, and more costly fires. Behind the flames, a new question arises: what will be the cost of this new climate reality for states, businesses, and territories?
Affected Regions
No international organization has published an official count of the total number of countries affected since the beginning of the month, as of July 28, 2026. However, data from European surveillance services and international news agencies show an exceptional concentration of major fires in several areas:
- France
- Spain
- Portugal
- Canada
- United States
- United Kingdom
- Tunisia
These territories are among the most affected by the ongoing wildfires.
France: A Situation Out of Control
In France, wildfires in the southwest have caused an extraordinary situation. According to the Associated Press (AP), a fire in the Gironde region has:
- Destroyed over 420 km² of vegetation
- Damaged or destroyed over 240 homes
- Led to the evacuation of approximately 220,000 people The fire has also generated a rare phenomenon called "pyrocumulonimbus," a storm created by the fire itself that can worsen its spread.
Spain: Multiple Major Fires
In Spain, several significant fires have affected different regions. According to Reuters, the fires have been fueled by:
- Extreme temperatures
- Highly dry vegetation
- Weather conditions favorable to rapid fire spread Thousands of people have had to be evacuated.
Canada: Ongoing Wildfire Activity
In North America, Canada remains confronted with high wildfire activity. The European Copernicus Atmosphere Monitoring Service (CAMS) reported that fires in central Canada in July have generated significant smoke emissions affecting several regions, including the United States and the Atlantic Ocean. These smoke emissions not only represent an environmental problem but also disrupt:
- Transportation
- Air quality
- Certain economic activities
Tunisia: A Warning Signal
According to several sources, approximately 900 fires were recorded in 72 hours between July 20 and 22, while the country was experiencing a significant heatwave. Six major fires were recorded in July, ravaging over 4,000 hectares of forests, particularly in:
- Zaghouan
- Béja
- Bizerte
- Le Kef
- Jendouba For a country where forest resources play a crucial economic and social role (agriculture, livestock, rural tourism, and soil protection), these fires represent a cost that far exceeds the sole intervention of firefighters.
The Role of Climate Change
Scientists do not say that a specific fire is always directly caused by climate change. However, the scientific consensus is that global warming increases the probability of conditions favorable to large fires:
- Higher temperatures
- Prolonged droughts
- Drier soils
- Longer fire seasons The World Meteorological Organization (WMO) and several international scientific organizations have been warning for several years about the increase in extreme climate events related to global warming. More frequent and intense heatwaves create an environment where fires can become more explosive.
