Can the World Cup cope with extreme heat?

The 2026 World Cup, the first to span three countries—USA, Mexico, and Canada—is facing unprecedented climate challenges as global temperatures rise. With the tournament expanding to 48 teams and 104 matches, the event's carbon footprint is projected to be the largest in history, largely driven by fan air travel. A fan from Cape Town could generate over 5.9 tons of CO2 just following their team to the final—equivalent to 59,000 plastic bags. Meanwhile, extreme heat is already endangering players and fans alike, with humid conditions in cities like Miami and Texas posing serious health risks, including exertional heat stroke. Despite FIFA's new mandatory hydration breaks and cooling measures, experts warn these steps may not be enough. The episode reveals that climate change is already reducing playable days in regions like sub-Saharan Africa and Oceania, raising urgent questions about whether future World Cups can be held in their current format. The hosts argue that while the tournament brings joy and global unity, its environmental and health costs are too high—and that athletes, as trusted public figures, must use their platforms to amplify climate action. The conversation also challenges the myth of long-term economic benefits for host cities, citing decades of evidence showing minimal tourism gains and no lasting infrastructure improvements. Instead, the real winners are the players, the sport, and the global fan community.
