Climate change is increasingly reshaping the world of sports, forcing organisers and athletes to adapt to rising temperatures, extreme weather events and environmental disruptions. A new report by the World Economic Forum warns that the global sports industry valued at 2.3 trillion dollars annually is facing mounting risks due to climate-related challenges.
From extreme heat affecting player safety to declining snowfall disrupting winter sports, climate change is no longer a distant concern but an immediate reality for sporting events worldwide. Experts say that as global temperatures continue to rise, the frequency and intensity of extreme weather events are also increasing, directly impacting when, where and how sports are played.
Major Events Already Feeling The Heat
The impact of climate change is already visible in some of the world’s biggest sporting events. During the 2026 Los Angeles Marathon, runners were offered an option to finish early due to dangerously high temperatures, highlighting growing concerns about athlete safety.
Similarly, the Winter Olympics have faced significant challenges due to reduced snowfall. Recent games in northern Italy relied heavily on artificial snow and expanded venues to cope with unpredictable weather. Experts warn that by 2040, only about 10 countries may remain suitable to host the Winter Olympics due to declining snow conditions.
Tennis tournaments are also adapting. At the 2026 Australian Open, matches were suspended during extreme heat, while new policies now allow cooling breaks for players. Rising temperatures and humidity have led to increased cases of heat-related illness among athletes, forcing organisers to introduce safety measures.
Changing Schedules And Venues Across Sports
Traditional sporting calendars are being reconsidered as climate conditions worsen. Events like the Tour de France, historically held in July, may shift to cooler months to reduce heat stress on cyclists. Studies show that extreme heat exposure during such endurance events has increased significantly in recent years.
Winter sports are among the most affected. Ski resorts across Europe and North America are experiencing shrinking snow seasons and reduced snow cover. Research indicates that one in eight ski resorts worldwide could face little to no snow by the end of the century. Countries like France and Italy have already seen hundreds of ski resorts shut down due to lack of snow.
Marathons are also being rescheduled or modified. Some races now start earlier in the morning or even late at night to avoid peak heat. However, even these adjustments are not always enough, as high temperatures and humidity continue to pose risks to participants.
Wildfires And Air Pollution Add New Challenges
Beyond heat and snow loss, air quality has emerged as another major concern. Wildfires, intensified by climate change, are disrupting sports events by creating hazardous conditions. In the United States, wildfire smoke has forced the cancellation and rescheduling of games across leagues, including baseball, basketball and soccer.
Poor air quality not only affects athlete performance but also poses serious health risks to players and spectators. Scientists warn that worsening pollution levels linked to climate change could lead to millions of premature deaths globally in the coming decades.
Interestingly, rising temperatures are even altering game dynamics. Studies have shown that warmer air can reduce resistance, leading to an increase in home runs in baseball, demonstrating how climate change is subtly influencing sports performance itself.
As climate pressures intensify, experts emphasise the urgent need for adaptation strategies, including flexible scheduling, improved infrastructure and stronger safety protocols. The report highlights that without decisive action, climate change could fundamentally alter the future of sports, affecting not only athletes but also economies and communities that depend on them.
