What caused the deadly floods in Valencia in 2024?

Man-made climate change significantly intensified the rainfall that caused the deadly flash floods and landslides in Spain's Valencia region in 2024.

How much did climate change increase rainfall during the Valencia floods?

In today's warmer world, simulations showed a 21% increase in the rainfall rate and a 56% increase in the area with heavy rainfall compared to pre-industrial times.

What role did sea temperatures play in the Valencia flooding?

Record-high sea temperatures increased atmospheric water vapor, amplifying the storm's intensity and leading to heavier, more widespread rainfall.

Valencia Floods: Climate Change Fueled Deadly Rains

In 2024, the Valencia region of Spain experienced devastating flash floods and landslides, exacerbated by man-made climate change. This climate event led to at least 230 fatalities and an estimated €29 billion in damages.

Scientific research indicates that global warming intensified the rainfall, making sudden, heavy rains more widespread. Simulations revealed a 21% increase in rainfall rate and a 56% increase in the area experiencing over 180 millimeters of rain during a critical six-hour period in today's warmer climate compared to pre-industrial times.
