[1/3] People cool off near the Spanish Steps, during a heatwave across Italy, as temperatures are expected to rise further in the coming days, in Rome, Italy July 18, 2023.
They have added fresh urgency to talks this week between the United States and China, the world's top greenhouse gas polluters.
"Whilst most of the attention focuses on daytime maximum temperatures, it is the overnight temperatures which have the biggest health risks, especially for vulnerable populations," it said.
The European Union's Copernicus Climate Change Service says 2022 and 2021 were the continent's hottest summers on record.
In a large part of the territory, night-time temperatures were in the top 5% of the highest recorded at this time of year.
