Athletes feel the heat, and tipping points inch closer

Hot Topic: Olympics, present and future. Soaring temperatures blanketing Paris during the 2024 Olympics provide the latest example of climate change's impact. Scientists say an extreme heat dome scorching North Africa and various Mediterranean countries this month, including France, would have been impossible without human-caused climate change.

With fossil fuels reported to have increased the heat dome’s effects in the Mediterranean by 2.5 °C to 3.3 °C, Olympians and spectators alike have been socked by high temperatures. Many Olympians have had to import air conditioners and wear ice vests to mitigate heat risks and safely participate in the Games.

After 1 in 100 athletes suffered heat-related illness at the Tokyo Olympics, the International Olympic Committee (IOC) created a strategic roadmap to boost sustainability and minimize carbon emissions at future Games. The plan included using existing or temporary venues, building new venues with recyclables and solar power, and using renewable energy and geothermal cooling systems to enhance energy efficiency.?

Despite these changes, critics still point to the enormous environmental impact of such a large-scale event and the resources needed to make the Olympics possible. Paris, for example, spent $1.5 billion to improve the water quality in the Seine for the men’s triathlon, but heavy rainfall continued to push wastewater into the river. The IOC had to postpone the triathlon for several days until the water finally tested safe enough for swimming.

Scientists agree that the future of both the Summer and Winter Olympics is at stake in our changing climate. The IOC has already delayed its selection of a host for the 2030 Winter Olympics, with the climate feasibility of several potential locations in question.?

An Axios analysis of CarbonPlan data found that by 2050, 60% of potential Summer Olympics locations will experience temperatures above 82°F, the recommended threshold for canceling continuous outdoor activity to avoid heat illness. And a climate study from The Lancet projected that by 2085, only eight cities outside of Western Europe would be cool enough to host the Summer Olympics—with the only potential U.S. venue being San Francisco.?

“Climate change crashed the Olympics. If the atmosphere wasn’t overloaded with emissions from burning fossil fuel, Paris would have been about 3°C [5.4°F] cooler and much safer for sport.”
