Scientists say the climate crisis caused by human greenhouse gas emissions is making extreme weather events such as heatwaves, droughts, supercharged storms and flooding more frequent and more intense.
Italy has experienced a long series of such events in recent years.
This year intense heatwaves and extreme droughts have impacted southern regions, with Sicily and Sardinia hit especially severely.
Meanwhile, heavy rainfall has led to flooding in Piedmont, Emilia-Romagna and Marche, prompting the authorities there to declare a state of emergency.
