Using Wet Bulb Globe Temperature (WBGT) as a metric, the analysis indicates that more games are expected to exceed the 26C and 28C thresholds recommended by FIFPRO for cooling breaks and postponement, respectively. While air-conditioned stadiums may mitigate risks for players, spectators at outdoor events remain vulnerable. The study concludes that without substantial adaptation and rapid mitigation of fossil fuel use, hosting summer tournaments in the northern hemisphere will become increasingly hazardous.","ai_generated":true,"unit":"wwatt-000101#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"There is a significant discrepancy between the heat stress thresholds recommended by the players' union (FIFPRO) and the official FIFA World Cup regulations.
