Climate Change Widened Valencia's 2024 Extreme Rain Footprint by 55%, Study Finds
Human-driven warming increased six-hour rainfall intensity by 21% and expanded extreme rainfall coverage by 55%, worsening the deadly 2024 Valencia flash floods, study finds.
- On February 17, 2026, researchers published a Nature Communications study finding Valencia's October 2024 deluge had a 55 percent larger area with about seven inches of rain in 24 hours.
- Researchers found short-term rainfall intensity rose about 21 percent over a six-hour period, using real-world data to simulate floods against preindustrial climate baselines.
- In just a few hours, more rain fell on Valencia than in an average year, triggering flash floods that swept away bridges, cars and even derailed a train.
- Scientists had long speculated climate change played a role and the study now quantifies that influence, but attribution scientists caution it remains difficult to assign exact warming shares to single events.
