Fabio d’ANDREA. – Personally, I believe so. Forecasts of climatologists predict in an average warmer world an increase in events of extreme intensity. However, to know if a particular disaster is a manifestation of climate change, you have to do specific calculations. Scientists use digital models for this: they reproduce on a virtual Earth the weather conditions on the day of the event (temperature, humidity, wind, etc.) and run this model a thousand times to measure the probability of such a disaster, at both under current climatic conditions and those before the industrial revolution.
