Une fois que tu sais

Three decades on from the disaster, Chernobyl shows signs of life again.

Since World War II North Americans have invested much of their newfound wealth in suburbia. It has promised a sense of space, affordability, family life and upward mobility. As the population of suburban sprawl has exploded in the past 50 years Suburbia, and all it promises, has become the American Dream. But as we enter the 21st century, serious questions are beginning to emerge...

Tobacco, climate change, pesticides,... Never has scientific knowledge seemed so vast, detailed and shared. And yet it appears to be increasingly challenged. It is no longer surprising to see private corporations put strategies in place to confuse the public debate and paralyze political decision-making. Overwhelmed by excess of information, how can we, as citizens, sort out fact from fiction? One by one, this film dismantles the workings of this clever manoeuvre that aims to turn science against itself. Thanks to declassified archives, graphic animations and testimonies from experts, lobbyists and politicians, this investigation plunges us into the science of doubt. Along with a team of experts (philosophers, economists, cognitive scientists, political men, or even agnotologists), we explore concrete examples of doubt making and try to understand the whole process and the issues behind it.

After one of the hottest years on record, Sir David Attenborough looks at the science of climate change and potential solutions to this global threat. Interviews with some of the world’s leading climate scientists explore recent extreme weather conditions such as unprecedented storms and catastrophic wildfires. They also reveal what dangerous levels of climate change could mean for both human populations and the natural world in the future.

Every day our changing climate pushes us closer to an environmental catastrophe, but for most the problem is easy to ignore. David Hallquist, a Vermont utility executive, has made it his mission to take on one of the largest contributors of this global crisis-our electric grid. But when his son Derek tries to tell his father's story, the film is soon derailed by a staggering family secret, one that forces Derek and David to turn their attention toward a much more personal struggle, one that can no longer be ignored. - Written by Aaron Woolf
