Spain's 2025 summer wildfires, which razed 400,000 hectares, rank among the world's most devastating climate disasters of the year, according to Christian Aid's annual review. This event continues a pattern of severe climate impacts placing Spain in international vulnerability rankings. Experts link these disasters to the continued expansion of fossil fuels and political delays in climate action.
Christian Aid has described Spain's 2025 wildfire season as “one of its most devastating fire seasons,” with 400,000 hectares of forest destroyed. This disaster joins other global events highlighted in its annual review, such as the January Los Angeles fires, which caused over $60 billion in damages and 31 direct deaths, plus 400 indirect.
Spain has frequently appeared in these rankings: in 2024 for the Valencia DANA floods and in 2023 for drought. “These disasters are not natural. They are the predictable result of the continued expansion of fossil fuels and political delays,” states Joanna Haigh, emeritus professor at Imperial College London and lead IPCC author.
Other impacts include November cyclones in Southeast Asia, with $25 billion in losses and over 1,700 lives lost; summer floods in China; Hurricane Melissa in the Caribbean; and drought in Brazil. In developing countries like Nigeria (May floods) and Congo (April), effects are severe though less economically quantified.
“This year has shown us, once again, the harsh reality of climate collapse,” emphasizes Patrick Watt, CEO of Christian Aid. “These disasters warn us of what awaits if we do not accelerate the phase-out of fossil fuels. The suffering caused by this crisis is a political choice driven by decisions to continue burning fossil fuels, which first and hardest hit the most vulnerable.”
The report notes that climate disasters have cost $28 trillion between 1990 and 2020, and highlights unusual events like Scottish wildfires (47,000 hectares) and Japanese snowstorms.
