Ahead of Paris 2024, and building on the first Rings of Fire report in 2021, elite athletes from across 15 sports – including 11 Olympians – join forces with leading climate scientists and thermal physiologists to examine the serious threat extreme heat poses to competitors at the Paris Olympics.

It includes:

• Analysis to show that the average temperature in Paris has risen by 3.1°C since 1924, the year of the last Olympics in France.
• The UN’s prediction that 2024 is on track to the hottest year ever, and Europe is the fastest-warming continent on the planet.
• A foreword from Lord Seb Coe, President of World Athletics, in which he warns that “with global temperatures continuing to rise, climate change should increasingly be viewed as an existential threat to sport”

Athletes express their concerns about the dangers to performance, health and even the fear of heat-related deaths.
