Why This Summer’s Wildfires Are 40 Times More Likely Due to the Climate Crisis

Barcelona has faced historic wildfires this summer, intensified by climate change. A study from World Weather Attribution (WWA) reveals that the odds of such extreme fires on the Iberian Peninsula have become 40 times greater due to prolonged heat, drought, and winds. Notably, from August 8 to 17, temperatures soared above 40°C for ten consecutive days, marking one of the hottest times ever recorded in the region.

The study highlights that global warming, now at 1.3°C above pre-industrial levels, will likely bring about extreme conditions every fifteen years. In contrast, before industrialization, such events were rare—occurring roughly once every 500 years. The current climate crisis has also boosted conditions for wildfires by 30% in intensity.

Theodore Keeping, a researcher at Imperial College London, underscores the unpredictability of these fires. “We are seeing fires that generate their own wind,” he explains. This is characteristic of sixth-generation wildfires that can outpace firefighting efforts and devastate large areas in a matter of minutes. A recent example was the Poniente fire earlier this summer.

Without climate change, the chance of experiencing ten consecutive days of extreme heat like those in August would be less than once every 2,500 years. Experts estimate that current conditions make such heat waves 200 times more likely and increase temperatures by 3°C above historical norms.

The fires this summer resulted in eight fatalities and consumed over 640,000 hectares across Spain and Portugal, accounting for two-thirds of the burned area in Europe. In Portugal, fires devastated 3% of the country’s land area, highlighting a grim summer.

According to the WWA report, fossil fuel emissions are a major driver of these extreme weather events. Experts urge a significant reduction in emissions to mitigate future climate impacts. Without action, Europe may face even worse wildfires in the coming years.

Additionally, poor forest management and rural abandonment have created more fuel for fires. Friederike Otto from Imperial College London stresses the need for better vegetation control in rural areas, especially on land left vacant by farmers. Collaboration across all government levels is essential to adapt effectively to these challenges.

Recent statistics indicate the economic repercussions of climate change are severe. Costly events like wildfires and natural disasters, such as the recent DANA in the Valencian Community, highlight the urgent need for action. According to a report from the European Environment Agency, unchecked climate change could lead to a staggering €12 billion annual cost in Southern Europe.

The situation is serious, but awareness and action can make a difference. By tackling the root causes of climate change, we can work toward safeguarding the environment and communities at risk.
