The extreme rainfall causing deadly flooding across western Germany and Belgium has been so alarming, many across Europe are asking if climate change is to blame.
Scientists have long said that climate change will lead to heavier downpours. But determining its role in recent weeks' relentless downpours will take at least several weeks to research, scientists said Friday.
"Floods always happen, and they are like random events, like rolling the dice. But we've changed the odds on rolling the dice," said Ralf Toumi, a climate scientist at Imperial College London.
