Harrison Ford warns about the climate emergency Sunday night in an interview broadcast on France 2 on the sidelines of the Cannes Film Festival. "Science is science, based on facts, it is not an opinion," said the American actor, denouncing those who "denigrate science" Ford's stance is neither a surprise nor news.

A few months earlier, at the Global Climate Action Summit, the actor had expressed his anger against climate sceptic policies and had already denounced the inaction of governments around the world.
