The United Nations climate secretariat has warned that extreme heat is expected to significantly affect the 2026 FIFA World Cup, which kicks off in Mexico on Thursday, with nearly a quarter of the matches likely to be played under dangerous temperatures.
The warning was issued on Monday at the opening of a 10-day climate conference in Bonn, Germany.
According to the secretariat, rising global temperatures driven by climate change will make extreme heat a major feature of the tournament, impacting players, spectators and host cities.
While footballers are expected to receive extensive medical support, the agency expressed concern for fans, noting that many could face prolonged exposure to high temperatures in fan zones, transport routes, queues, car parks and outdoor celebration areas.
The UN climate body also said the effects of extreme heat could be visible during matches, with players likely to conserve energy, leading to slower-paced games. Measures such as additional water breaks, earlier substitutions and the use of cooling towels are also expected.
UN Climate Change Executive Secretary Simon Stiell said the growing impact of heat on football reflects the broader consequences of climate change.
“It’s hot and getting hotter. That’s not random.
That’s climate change,” Stiell said, stressing that the continued use of fossil fuels such as coal, oil and gas is driving global warming.
He added that climate change is not only affecting sports but also threatening food production by reducing harvests and contributing to rising food prices worldwide.
The 2026 FIFA World Cup will be the largest edition of the tournament, taking place amid increasing concerns over the impact of extreme weather on major sporting events.
