Scientists and medical experts are sounding the alarm over potentially life-threatening conditions at the upcoming 2026 FIFA World Cup, urging the governing body to drastically strengthen its safety protocols.
In an open letter reported by BBC Sport, a coalition of climate researchers and sports scientists warned that rising temperatures across the United States, Canada, and Mexico pose a severe risk to both athletes and spectators.
The group is calling on FIFA to adopt the stricter heat protection standards proposed by FIFPRO, the global players’ union, to prevent heatstroke and other heat-related illnesses.
The urgency stems from a sobering analysis by the World Weather Attribution group, which suggests that the risk of extreme heat has nearly doubled since North America last hosted the tournament in 1994.
Data indicates that approximately 25% of matches could be played in conditions exceeding 26°C Wet Bulb Globe Temperature (WBGT)—a critical metric for heat stress—while several matches may surpass 28°C WBGT. “Player safety is an immediate and urgent concern because things can go wrong very quickly when people overheat,” warned Andrew Simms, the letter’s coordinator, who accused FIFA of “playing recklessly” with participant health.
In response to these mounting concerns, FIFA has pledged to implement a “tiered heat mitigation model” tailored to real-time weather data in each host city.
A spokesperson for the organization stated that dedicated meteorological monitoring will be in place to guide decision-making, including the potential for mandatory cooling breaks.
FIFA further defended its preparations by noting that kickoff times were scheduled specifically to avoid the hottest periods of the day, with high-temperature fixtures prioritized for climate-controlled, covered stadiums.
Despite these assurances, critics remain skeptical that current measures go far enough to counter the realities of a warming planet.
Beyond record-breaking heatwaves, experts cautioned that external factors like wildfire smoke and severe thunderstorms could further disrupt the summer tournament.
The debate highlights a growing crisis for international sports, as climate change raises fundamental questions about the viability of hosting major outdoor events during peak summer months in regions prone to extreme weather.
