Serving under the sun: Climate change is becoming a major factor in global sport
Extreme heat is forcing global sports like cricket, football, and tennis to adapt, with the 2026 FIFA World Cup and Indian Premier League facing dangerous conditions for players and fans. Experts warn that rising temperatures and humidity could make matches unsafe without stricter heat mitigation measures, including delayed starts and expanded cooling facilities.
Rising temperatures are reshaping outdoor sports, with organisers, scientists, and governing bodies scrambling to address heat risks. The Indian Premier League (IPL) 2026, set for India’s peak summer months, will see temperatures frequently exceed 40°C in cities like Delhi, Jaipur, and Ahmedabad. To protect players, teams are using hydration strategies, cooling vests, and extended recovery breaks between overs. The 2026 FIFA World Cup in the U.S., Canada, and Mexico faces even greater challenges, as nearly a quarter of matches could experience dangerous heat conditions. Scientists warn that Wet Bulb Globe Temperature (WBGT)—a measure combining temperature, humidity, wind speed, and solar radiation—could exceed the 28°C threshold, posing significant risks to athletes and spectators. A group of 20 experts from multiple countries has urged FIFA to delay matches when WBGT surpasses 28°C, extend cooling breaks to six minutes, and expand cooling facilities. Research by the World Weather Attribution group shows climate change has increased the likelihood of extreme heat at the 2026 World Cup compared to the 1994 tournament. Cities like Miami, Houston, Kansas City, and Monterrey are particularly vulnerable, with afternoon matches at high risk. FIFA has committed to a ‘tiered heat mitigation model,’ using real-time weather monitoring and meteorological support to adjust schedules and safety measures. Tennis is also adapting, with Wimbledon 2026 set to implement enhanced heat protocols following last year’s extreme temperatures in London. Organisers have installed over 100 water refill stations and distributed 6,700 reusable bottles to ensure player and spectator safety. The All England Lawn Tennis and Croquet Club will monitor conditions closely, adjusting protocols as needed. While FIFA claims its scheduling accounts for climate risks, researchers warn that even air-conditioned venues like Dallas’ semi-final stadium face a 29% chance of exceeding the 28°C WBGT threshold. The shift underscores how climate change is forcing sports to rethink traditional tournament structures, prioritising athlete and fan safety over rigid schedules.
