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 would spell trouble for organisers. A new study presenting “climate simulations to anticipate worst-case heatwaves during the Paris 2024 Olympics” has focused minds after it warned that the French capital faced a not insignificant risk of record-breaking high 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 and the idea was to warn policymakers that something even worse than 2003 could happen, that it’s possible,” 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, in the region of 1/100,” 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 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.

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 42.6 degrees Celsius (108.7 degrees Fahrenheit) in the capital. Organisers of the 2024 Paris Olympics, which will run from July 26 to August 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 as much as possible, in order to take necessary action,” a spokesperson told AFP.

Operational teams have run simulations looking 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 open-air 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 modelling. — AFP
