When Paris decided to host some swimming events in the Seine River, they took a big risk. Unfortunately for them, heavy rainfall brought devastating effects, forcing events to be rescheduled and raising concerns over athlete safety.
A Risky Bet: Swimming in the Seine
This year’s Paris 2024 Olympics have included some outdoor swimming events that were set to take place in the Seine River. However, this decision hinged on a variety of favorable conditions.
Severe Weather
During the games, high levels of rainfall led the hosts to be concerned about the quality of water. Several times, there were discussions about postponing, and possibly even canceling, parts of the outdoor swimming events.
Climate Change
Experts have linked the heavy rainfall in Paris this year with the increasing effects of climate change. Rising temperatures and unpredictable weather have made it even harder to maintain safe water conditions in the Seine.
Impact of Global Warming
A recent study found that global warming can lead to more extreme rainfall patterns, especially in Europe. This was clear as Paris hoped for a drier and more forgiving rain season, and was left disappointed.
Last-Minute Changes
The men’s triathlon was postponed due to concerns about water quality. This shows us how difficult it can be to rely on outdoor venues for events such as these.
Nearing Cancellation
There were many discussions about skipping the swimming portion of triathlon races, or coming up with another way of testing athletes. This would have been disheartening for the many athletes who have spent years training for these events.
Parlis’ Investment
Before the start of the games, Paris invested nearly €1.4 billion in order to improve the Seine water quality. This included constructing a massive basin that would collect the excess rainwater.
Questionable Solutions
The storage bin solutions were met with immediate criticism. Many viewed this as an outdated solution that couldn’t keep up with the intense rainfall brought on by climate change.
Paris Mayor Swims
Paris Mayor, Anne Hidalgo, jumped into the river before the opening ceremony, as a show that it was clean enough for the swimmers. However, this was viewed as more of a publicity stunt than an actual test of safety.
Significance of Paris
Paris has been a leader in climate discussions, so many were surprised by the city’s approach to these events. Paris held the biggest climate agreement in history, “The Paris Agreement,” over a decade ago, and the city was determined to host lower-emission games.
Challenges of Sewer Systems
Paris’ sewer system handles both stormwater and wastewater. The heavy rains overwhelmed the combination system, leading to more pollution in the Seine.
Criticism of the Decision
Many viewers were critical of the decision to use the Seine for hosting events. They believe that it was a gamble from the start – one that put the safety of athletes at risk.
A Bad Gamble
Metin Duran, a professor of civil and environmental engineering at Villanova University, said that the organizers “just gambled, flipped the coin and hope[d] for a dry season and it turned out to be the rainiest in the last 30 years.”
Water Quality Standards
Compared with the U.S., standards for pollution for the triathlon were actually four times weaker. This really raised questions about how safe an event with these conditions could be.
Safety of Athletes
It’s also important in these situations to prioritize the safety of athletes, who are swimming in unpredictable weather conditions and in water that barely passes the appropriate quality standards.
Triathlete Falls Ill
One Belgian athlete, Adrien Brifford, caught a stomach virus after swimming in the Seine River during a swim. This brought even more concerns about the health of these competitors.
The Need for Green Spaces
Some climate scientists suggest that cities could create more green spaces in the future, which would absorb more of the rainwater and reduce the amount of pollution in rivers and waterways.
Lessons for Future Olympics
Future Olympic hosts, such as Los Angeles in 2028, might consider some of the risks that climate change brings when planning their events. Weather is only getting more unpredictable as the world gets warmer.
Preparing for a Wetter World
Heavier and more frequent rains are becoming a reality. It’s important that in future Olympic planning, we consider ways to keep athletes safe against the devastating effects of climate change.
A Wake-Up Call
The challenges faced by Paris in hosting these events should become a wake-up call for cities to not only plan their events better, but to also take climate threats more seriously. Seeing these effects on such a global platform really highlights how important it is to take action against global warming.
