In brief
Experts from around the world are connecting climate change to the recent intense floods in Spain, noting that rising temperatures have exacerbated the impact of traditional weather phenomena.
Recent severe flooding in Spain has been closely linked to the impacts of climate change, as highlighted by a team of international scientists. They contend that while it’s challenging to pinpoint climate change as the direct cause of a single extreme weather event, its role in intensifying such occurrences has become unmistakable. Dr. Friederike Otto from Imperial College London stated, “These explosive downpours were intensified by climate change,” emphasizing how a warmer atmosphere retains more moisture, which leads to heavier rainfall.The phenomenon driving the recent deluge, known as "gota fría" or cold drop, traditionally manifests in Spain during autumn and winter when cold air collides with the warm waters of the Mediterranean Sea. Due to rising ocean temperatures, this interaction generates towering clouds that release substantial rainfall. Research indicates that climate change has caused this rainfall to increase by 7% for every 1°C temperature rise, posing significant risks to already strained infrastructure.Additionally, hotter summers are hardening soil, diminishing its capacity to absorb water. Prof. Mark Smith from the University of Leeds noted, “Increased rainfall extremes coupled with baked soils worsen the flooding situation.” This year has also seen other regions suffer from similarly devastating storms, like Storm Boris in September, which was also intensified by global warming conditions in the Mediterranean.Despite extensive weather research, the unpredictability of intense thunderstorms poses a challenge for meteorologists, complicating the issuance of timely and precise warnings. Dr. Linda Speight from Oxford University remarked that pinpointing where heavy rainfall will occur is often impossible, making it difficult to advise people adequately. Moreover, the recent disasters have exposed the inadequacy of existing infrastructure, originally designed for past climate conditions, in coping with current and future extreme weather events.
