World Cup 2026 stars are being warned they could face serious health dangers, including heat stroke, due to extreme temperatures and humidity. Experts highlight climate change as a key factor threatening players and fans across the United States, Canada, and Mexico.
Climate Change at the Forefront
UN Climate Change reports that extreme heat conditions have doubled since the 1994 World Cup in the US. Experts believe 26 of the 104 games will be played in hazardous heat, with five matches potentially facing postponement-level temperatures. Miami, Kansas City, and Philadelphia are most at risk, but the semi-finals and final in New Jersey are also vulnerable.
Impact on Players and Fans
Simon Stiell, Executive Secretary of UN Climate Change, stated: "We’re all watching the game, but it’s stopped – because it’s too hot. Hot for players, for fans, for everyone. It’s hot and getting hotter. That’s not random. That’s climate change." He emphasized that burning fossil fuels traps heat in the atmosphere, affecting not only football but also food supplies.
USA midfielder Malik Tillman added: "I know wildfires become more frequent because of climate change. We as human beings have to adapt to ensure future generations enjoy those memories and protect the sport we love."
Game Adjustments Needed
World Cup games are expected to be slower due to extreme heat limiting player performance, with more substitutions required. FIFA has introduced heat breaks, reviewed kick-off times since the Club World Cup, and is using three indoor stadiums. They have also engaged with player unions after FIFPro expressed concerns about temperature dangers.
