Football players are adding their voices to warnings that FIFA’s heat-safety plans for the 2026 World Cup in the United States, Mexico and Canada may not be enough. The renewed calls follow earlier appeals from health experts and scientists who said FIFA’s current weather mitigation measures are inadequate for protecting players and others during periods of extreme heat. The concerns are linked to global warming and point to increased risk of dangerous temperatures since 1994, with one report noting scientists warn FIFA that “gruelling heat” could affect around a quarter of World Cup matches. A key proposal cited across the coverage is reviewing match scheduling and the handling of conditions above a specified heat-stress threshold, including use of Wet Bulb Globe Temperature (WBGT) as a benchmark. FIFA, meanwhile, says it has prepared for extreme heat and has emergency protocols in place, including a dedicated Heat Illness Mitigation and Management Task Force made up of medical and operational experts. Players’ letter(s) and the scientific criticism put further pressure on FIFA to reassess whether its mitigation and management approach is sufficient for the forecast conditions.
