The upcoming 2026 FIFA World Cup, set to take place across the United States, Mexico, and Canada, faces serious challenges due to rising temperatures. An analysis by the climate research group World Weather Attribution indicates that almost 25% of the 104 matches are likely to occur under heat conditions that exceed safety thresholds established by the global players' union FIFPRO. Researchers estimate that around five matches could be played in conditions unsafe enough to warrant postponement. The risk of dangerous heat has intensified significantly since the 1994 World Cup, with the likelihood of high Wet Bulb Globe Temperature (WBGT) conditions now nearly double. FIFPRO recommends mandatory cooling interventions when WBGT exceeds 26°C and suggests postponing matches when it surpasses 28°C. FIFA has announced measures such as hydration breaks and cooling infrastructure to mitigate these risks. However, several host cities lack air-conditioned stadiums, raising concerns for players and fans alike. Experts argue that the viability of summer tournaments in increasingly hot regions may need reevaluation, with suggestions to adjust the World Cup calendar to avoid health risks.
