Reacción a "The heavy rainfall of the Valencia DANA was mainly due to climate change, according to a study"

This is the second study, the first one by WWA (World Weather Attribution) on 2 November. The second study by ClimaMeter is consistent with the one published by WWA. In my view, there is no doubt that extreme events of this type are more likely now with anthropogenic climate change than they would be without it. Attribution studies put the numbers by how much an extreme event has become more likely or intense. We know that with every 1°C increase in global temperature, the amount of water vapour in the atmosphere can increase by about 7%. The more water vapour, the more intense these types of events can become.

One more point: drought and extreme precipitation are two sides of the same coin. Warmer temperatures increase evaporation, which reduces surface water and dries out soils and vegetation.
