Good news: the 2026 FIFA World Cup is coming to North America. Bad news: roughly a quarter of all games could take place under heat and humidity conditions that scientists are classifying as genuinely dangerous for both players and fans, according to a warning from academics reported by Sky News.
Climate change, ever the uninvited guest, has apparently decided to show up to football's biggest party with a flamethrower. Experts are raising red flags about the combination of soaring temperatures and brutal humidity levels at host venues across the United States, Canada, and Mexico - a trio of countries that, climatologically speaking, can go from "pleasant summer afternoon" to "surface of Venus" with minimal warning.
Why heat plus humidity is a nightmare combo
It's not just the heat - it's the wet blanket of moisture that comes with it. High humidity prevents the human body from cooling itself efficiently through sweat, meaning that even temperatures that might seem manageable on paper can become medically hazardous in practice. For professional footballers sprinting around a pitch for 90-plus minutes, that's not just uncomfortable - it's a genuine health risk.
Fans packed into stadiums don't get a free pass either. Sitting in the stands under punishing sun and humidity is no picnic, and large crowds generate their own additional heat. The academics cited in the Sky News report warned that conditions at approximately one in four matches could reach levels that pose real danger to human health.
So what can organisers actually do?
Some of the American venues are already equipped with climate-controlled or domed stadiums, which will help. Scheduling games during cooler parts of the day - early morning or evening - is another lever FIFA could pull. However, the tournament's global broadcast commitments often dictate kickoff times more than player welfare does, which is a whole separate conversation nobody in Zurich seems eager to have.
This warning arrives as part of a broader pattern of major sporting events colliding with climate realities. The Tokyo 2020 Olympics, Qatar 2022, and several tennis grand slams have all faced serious scrutiny over heat management in recent years.
With the tournament scheduled for the summer of 2026, organisers still have time to adapt - but experts are clearly signalling that ignoring the forecast is not an option. Climate change waits for no offside flag.
