The heat wave in Saudi Arabia blamed for the deaths of 1,300 people on the Hajj pilgrimage this month was made worse by climate change, a team of European scientists said on Friday.
Temperatures along the route from June 16 to 18 reached 47 degrees Celsius at times and exceeded 51.8 C at Mecca's Great Mosque.
The heat would have been approximately 2.5 C cooler without the influence of human-caused climate change, according to a weather attribution analysis by ClimaMeter.
