Paris may be hottest ticket of the summer

PARIS — Scorching summer heat is hard to imagine now in mid-winter Paris, but in six months’ time, when the world’s athletes arrive for the Olympics, another pounding heatwave might spell trouble for organizers.

A new study presenting “climate simulations to anticipate worst-case heatwaves during the Paris 2024 Olympics” has focused the minds of those in charge, after it warned that the French capital faces a “not insignificant risk” of record-breaking summer temperatures.

The research, published in December in the Npj Climate and Atmospheric Science journal, looked at the risk of a two-week heatwave that would surpass the all-time record hot spell seen in Paris in 2003.

“In 20 years, the climate has changed. The idea was to warn policymakers that something even worse than 2003 could happen,” lead author Pascal Yiou told AFP.

“In the 20th century, it wasn’t possible to go beyond this record, but now we cannot only equal it, but surpass it with a probability that is ultimately quite high,” he added.

A separate study in the Lancet Planet Health journal last May found that Paris had the highest heat-related death rates of 854 European towns and cities, partly due to its lack of green space and its dense population.

The statistics were also heavily skewed by the events of 2003, when 15,000 people died, most of them vulnerable, elderly people living on their own, sparking a bout of national soul-searching.

Stress testing

In the last five years, Paris has witnessed a series of blistering summers that have seen heat records crumble.

A new all-time temperature peak was set in July 2019, when the Meteo-France weather service clocked a sizzling 42.6 C in the French capital.

Organizers of the 2024 Paris Olympics, which will run from July 26 to Aug 11, and the Paralympics, which start in late August, say they are “fully aware” of the climate-related risks to the Games.

“Heatwaves and extreme weather events are factors that we take into account, and that we are preparing for them as much as possible, in order to take necessary action,” a spokesperson told AFP.

Operational teams have run simulations that look at the consequences of shifting some outdoor events to earlier or later start times to avoid the midday heat.

The athletics events, particularly the marathon, as well as tennis or beach volleyball, are all seen as being vulnerable to the effects of punishing sunshine and high temperatures.

Young and fit athletes might also prove more resistant than spectators, who will likely face queues to enter venues and potentially hours without shade in openair stadia.

The head of the French agency responsible for building the Olympics venues, Nicolas Ferrand, reassured a Senate hearing that all indoor facilities had been built with global heating in mind.

“We checked that all of our buildings would be comfortable in the summer of 2050,” he said last month, adding that the national weather office and IT consultancy firm Dassault Systemes had helped with the modeling.

AC issue

Another area of ongoing concern is the athletes’ village in northern Paris, which has been built without air conditioning as part of efforts to set new environmental standards for the Paris Games.

Instead, the riverside tower blocks have natural geothermal cooling systems, as well as sunshades, planted areas, and wind ventilation.

They guarantee an indoor temperature at least 6 C lower than outside — something viewed as insufficient by some attending nations.

“Air-conditioning at the village has been an issue,” a European diplomat involved in Olympics coordination told AFP on condition of anonymity.

As a compromise, French organizers are now offering to provide portable air conditioners to visiting delegations at their expense.

Torrid Tokyo

The last Summer Olympics in Tokyo is widely thought to have been the hottest on record, with temperatures regularly above 30 C, coupled with an 80 percent humidity.

Tokyo organizers moved the race walk events and two marathons to locations 800 kilometers north of the capital city in the hope of finding cooler weather, which, unfortunately, did not really materialize.

Despite a range of heat management measures, including misting stations, many athletes struggled, including Russian tennis player Daniil Medvedev who wondered aloud on court if he might die.

Many athletes are adapting to climate change by doing more hotweather training, either at overseas camps or in specially designed bubbles that can artificially increase heat and humidity.

Speaking after Tokyo, World Athletics president Sebastian Coe warned that the “new norm” was competing in “really harsh climatic conditions”.
