Extreme Heat Emerges as a Major Threat to the 2026 World Cup. The 2026 FIFA World Cup faces growing scrutiny over the risks posed by extreme summer heat across host cities in the United States, Canada and Mexico. Rising temperatures linked to climate change could endanger both players and spectators during the tournament, according to experts. Scientists warn that a quarter of the matches could be played under heat conditions that exceed safety thresholds, especially in cities such as Miami, Kansas City and New York. Researchers argue that heat stress can impair athletic performance, increase the risk of dehydration and heat-related illness, and create significant challenges for fans attending matches. FIFA has introduced mitigation measures including hydration breaks and heat-monitoring protocols, but some experts contend that existing safeguards do not go far enough. Climate experts say conditions are substantially hotter than when the United States last hosted the tournament in 1994, which are attributed to human-caused climate change. The 2026 World Cup may serve as a critical test of how global sport adapts to a warming world.
