With this year's theme "Climate change: attenuation and adaptation," the ITER booths at Fête de la Science events in Manosque, Marseille, and Villeneuve-Loubet (near Nice) on the weekends of 8/9 and 15/16 October were particularly well attended. Thousands of visitors came by the ITER stands and left with a better understanding of why the seven ITER Members have united to create the unique ITER experiment.
