The Valencia floods of October 29 will go down in history as the deadliest disaster in modern Spanish history and the most catastrophic flood-related event in Europe in the past 50 years, claiming the lives of more than 229 people. One month on, the echoes of the tragedy continue to reverberate. The devastation on the ground remains palpable as communities struggle to recover from the catastrophic damage. Meanwhile, politicians are embroiled in a blame game over who is responsible, with potential legal consequences looming, while scientists work to understand the causes and scale of the disaster. “Climate change kills,” said the Spanish PM Pedro Sánchez shortly after the disaster during COP29 in Baku, a bold statement linking both events immediately. But what do experts say?

In a report published shortly after the catastrophe, they released a rapid attribution analysis, where they found that the DANA, the weather event responsible for the floods, had been 15% more intense due to climate change. “Climate change has increased the intensity of the flooding,” Davide Faranda, a co-author of the study, told Catalan News. The study compared the event with similar meteorological events in the region and found that the DANAs had 15% more moisture and were 3°C warmer, leading to more intense rainfall.

The role of climate change is minor for the moment, or we do not yet have enough statistics to prove it,” he explains. While Pino does not dispute the study’s conclusion that 15% of the DANA’s intensity was linked to climate change, he believes that even without that 15%, “the disaster would have been more or less the same.” The scientist adds that one of the problems with these catastrophic floods is that people have been living in areas prone to extreme weather “without taking it into account.” “We are really exposed to these types of floods, but we’ve spent decades building houses and infrastructure in areas where water is supposed to flow, regardless of that fact,” he says.
