“Once you know” by Emmanuel Cappellin – Sciences et Avenir

OVERLOAD. “Once you know” brings us together with specialists in climate and energy issues, but also with civil society activists. With this documentary, Emmanuel Cappellin and Anne-Marie Sangla give substance to the inner journey that personifies the problems of global warming. This personal involvement allows us to capture the messages transmitted by the film and does not leave the viewer in a simple position of observer in front of these subjects who may seem insurmountable.

“Those who know”

A bucolic opening to settle into the atmosphere of the film … After having tasted agriculture, zero waste, retirement in the East, the absence of deeper answers is felt for Emmanuel Cappellin. It was then that a series of interviews with climate specialists began. Jean-Marc Jancovici stands out for the scientific precision of his comments, particularly on energy issues, and for his frankness that he touches where it bothers. Also noteworthy are the interventions of Richard Heinberg, an expert in the depletion of oil resources who works for a sustainable transition of cities. Shocking moments closer to the daily life of “those who know” and who have to live with them. The documentary filmmakers’ camera also takes us into refuge spaces such as gardening or the violin, which are breaths of lightness in the face of the severity of climatic struggles. It is also a sensory elevation: far from the static documentary, there is a true aesthetic work in the articulation between the images and the text. If the substance is difficult, the form is artistic. And it feels good.

Hold on to the collective

Personal journeys and emotions, the film highlights the fact that we are not alone in the awareness of climate problems and the resulting ecological anxiety. But what solutions do we have available? Warming has long been palpable in some countries like Bangladesh: Saleemul Huq, an expert with the Intergovernmental Panel on Climate Change (IPCC), is the voice of emerging countries at climate conferences (COP). It is also participating locally in a transition that is bearing fruit. Adaptation of buildings to rising water levels, transformation of rice farming into fish farming … immersed in a country that had no choice but to adapt. For them it was yesterday, for us it is now. An example to follow?

With German geographer Susanne Moser and collectives like Extinction Rébellion or images of activists blocking a coal mine in Germany, the film shows how some are tackling this issue. Review the solutions to mobilize and get out of the wait-and-see attitude. But it is in Saillans, in the Drôme, in the director’s village where the example of transition is most striking. Being in France allows us to better understand these realities, to better appropriate them. This is where the intervention of the co-inventor of collapsology Pablo Servigne and the illustrated life scenes make us want to get out of the stagnation at our level, and act for a necessary change.
