Scientists Warn FIFA’s Heat Safeguards Inadequate for 2026 World Cup

Core Event: Heat Protocols Inadequate
An open letter from a coalition of health, climate and sports performance experts says FIFA’s heat-safety guidelines for the 2026 World Cup are inadequate and impossible to justify. Letter urges longer cooling breaks and protocols for delaying or postponing matches under extreme heat.
Data & Impact
World Weather Attribution (WWA) modeling shows 14 of 16 venues could face heat when temperature, humidity, wind and solar radiation combine. About one-quarter of 104 matches (?26) may reach Wet-Bulb Globe Temperature (WBGT) of 26 °C or higher, a level that can impair elite performance and raise heat-stroke risk. Five games could exceed 28 °C WBGT, FIFPRO postponement threshold, and six Miami matches have a near-certain chance of surpassing 26 °C. Most exposed sites are Miami, Kansas City and East Rutherford, New Jersey, final venue.
Official Statements
FIFA says it is committed to protecting health and safety of players, officials, fans, and that climate-related risks are integrated into planning. Organisers moved kickoff times later, mandated three-minute hydration breaks at halftime and introduced cooling periods. FIFA’s postponement rule activates when WBGT exceeds 32 °C.
Criticism & Opposition
Coalition says FIFA’s measures fall short of science. A 30 °C day in dry breezy conditions differs markedly from same temperature with high humidity and sun, which reduces evaporative cooling. Without safeguards—shaded areas, ice towels, cold fluids, warm-up schedules and medical monitoring—players risk heat-related illness and spectators with pre-existing conditions face greater risk.
Conflicting Thresholds
FIFA’s postponement rule triggers above WBGT of 32 °C, whereas FIFPRO recommends delaying matches at 28 °C WBGT. WWA analysis predicts one-in-eight chance of WBGT >= 26 °C for final, highlighting a gap between policy and risk assessments.
Next Steps
Scientists call on FIFA to extend cooling breaks, adopt postponement at WBGT thresholds, increase shade and hydration stations, and ensure medical staffing at venues. WWA urges climate-adaptation measures, including air-conditioning and reduction of fossil-fuel emissions, avoid “cancellation-level” heat.
