In brief
The European Union faces its worst wildfire season to date, with over one million hectares burned. Climate change is linked to increasingly severe fire seasons, particularly affecting the Iberian Peninsula. Spain and Portugal are reported to have sustained record amounts of land burned, resulting in environmental and air quality degradation. The implications of these wildfires extend further, contributing to higher carbon dioxide emissions and complicating fire management strategies.
A record one million hectares - equivalent to about half the land area of Wales - have burned across the European Union so far this year, making it the worst wildfire season since records began in 2006.
Spain and Portugal have been hit especially hard, with roughly 1% of the entire Iberian Peninsula scorched, according to EU scientists.
The worsening fire season in the Mediterranean has been linked directly to climate change in a study by the World Weather Attribution group at Imperial College London.
Experts warn that more frequent and severe fires across Europe are likely to continue in the future.
More than two thirds of the area burned in the EU is in Spain and Portugal alone. In Spain, over 400,000 hectares have burned since the beginning of this year up until 26 August, marking more than six times the Spanish average for this time period between 2006 and 2024.
Portugal has also registered a record burn area of 270,000 hectares so far - almost five times the average for the same period.
The combined burn area across the Iberian peninsula this year is 684,000 hectares - four times the area of Greater London, and much of it occurred in just two weeks.
The fires have devastated forested areas in northern Portugal and Spain's north-western regions of Galicia, Asturias, and Castile and León. Major routes on the Camino de Santiago pilgrimage network have been impacted, affecting tourism in the region.
Smoke from these fires has severely degraded air quality, with winds carrying smoke as far as France and the UK.
Climate change is exacerbating the conditions conducive to wildfires, producing a vicious cycle where fires also release significant amounts of CO2 into the atmosphere. CO2 emissions from fires in Spain this year have reached a record 17.68 million tonnes, surpassing the total annual CO2 emissions recorded from wildfires in the country since 2003. This amount exceeds Croatia's total annual CO2 emissions for 2023.
Firefighting efforts span across Europe, and a study has indicated that human-induced climate change has made fire-prone conditions in Southern Europe about 10 times more likely.
The increasing frequency and severity of wildfires pose significant challenges for fire management and could threaten long-term ecosystem stability. Experts emphasize the urgent need for better vegetation management and a transition away from fossil fuels to mitigate these catastrophic events.
