The temperature of the Mediterranean Sea has hit a record high this week.
Its average surface temperature hit 28.71C around July 24, beating the previous record of 28.25C set twenty years ago.
Researchers at the Barcelona-based Marine Sciences Institute said it was the highest temperature since 1982.
The temperature was measured using satellite data from Copernicus, the earth observation arm of the European Union’s space programme. Copernicus has yet to verify the record temperature.

Delphine Thibault, an associate professor in oceanography at Aix-Marseille University, told The Connexion that sea temperatures of 28C had been recorded recently near Marseille.
The waters near Menton, meanwhile, hit 29.47C on July 21, she added.
Dr Thibault went on to discuss the dangers of a warmer Mediterranean Sea.
“85% of red gorgonian coral died last year because of the heat,” she said. A similar scenario played out in 1999, she added.

“28 degrees is high. We need to see if it is on track to be sustained for weeks,” said Dr Thibault.
But she clarified it is much worse if such surface temperatures are replicated at depths of 30 or 40 metres, as was the case last year.
Dr Thibault added warmer temperatures could bring creatures that usually inhabit hotter waters - such as the red lionfish, rabbitfish or the rhopilema nomanica jellyfish - nearer to France. That, she added, could change the entire marine ecosystem.
