Climate Change Driving Extreme Heat at 2026 World Cup, Scientists Warn
Scientists have warned that climate change is playing a major role in the extreme heat affecting players, officials and fans at the 2026 FIFA World Cup, raising fresh concerns about athlete safety and the future scheduling of major sporting events.
According to researchers from the World Weather Attribution group, the intense temperatures experienced across parts of the United States and Canada during the tournament have been made significantly more likely and more severe by human-induced climate change. They said the prolonged heatwave is linked to greenhouse gas emissions from the burning of fossil fuels.Several World Cup matches have been played under sweltering conditions, with heat index values in some host cities reaching dangerous levels. Medical experts have cautioned that prolonged exposure to such temperatures increases the risk of dehydration, heat exhaustion and heatstroke for both players and spectators.The global football players’ union, FIFPRO, has expressed concern over the conditions, urging tournament organisers to strengthen heat protection measures. The organisation has recommended additional cooling breaks, adjustments to kick-off times and clear protocols for postponing matches when temperatures exceed safe limits.
Researchers noted that while FIFA has introduced measures such as hydration breaks and improved weather monitoring, the current tournament demonstrates the growing challenges climate change poses to outdoor sporting events. They warned that extreme weather is becoming more frequent and intense, requiring organisers to adapt future competitions accordingly.The warning comes as many regions across North America continue to experience unusually high temperatures, placing additional pressure on power grids and public health systems. Scientists say the trend highlights the broader impact of climate change beyond sport, affecting communities, infrastructure and everyday life.With the World Cup attracting millions of viewers worldwide, experts believe the tournament has become another visible example of how rising global temperatures are influencing major international events. They are calling for stronger climate action alongside practical measures to protect athletes and fans from the increasing risks posed by extreme heat.
