L'interview que nous reprenons ici, de Jean-Marc Jancovici, s'inscrit parfaitement dans le cadre de notre nouvelle série consacrée aux enjeux énergétiques et au changement climatique. Elle témoigne en effet de l'urgence de la transition énergétique et, surtout, de la nécessité de faire le deuil, au plus vite, du carbone, dans nos modes de production, de vie… Face au caractère désormais inéluctable du réchauffement climatique et de ses multiples conséquences, Jean-Marc Jancovici invite à accepter le plus vite possible de renoncer aux énergies carbonées, à travailler dès aujourd'hui à l'adaptation au changement climatique (et non plus seulement à la lutte contre ce phénomène). Enfin, il montre que face à de tels défis de civilisation, la France n'est pas démunie, mais qu'il importe que son action s'inscrive dans une politique claire et pédagogique pour convaincre et associer tous les citoyens à un projet commun de transition énergétique. S.D.

"La rencontre entre un auteur majeur de la bande dessinée et un éminent spécialiste des questions énergétiques et de l'impact sur le climat a abouti à ce projet, comme une évidence, une nécessité de témoigner sur des sujets qui nous concernent tous. Intelligent, limpide, non dénué d'humour, cet ouvrage explique sous forme de chapitres les changements profonds que notre planète vit actuellement et quelles conséquences, déjà observées, ces changements parfois radicaux signifient. Jean-Marc Jancovici étaye sa vision remarquablement argumentée en plaçant la question de l'énergie et du changement climatique au coeur de sa réflexion tout en évoquant les enjeux économiques (la course à la croissance à tout prix est-elle un leurre ?), écologiques et sociétaux. Ce témoignage éclairé s'avère précieux, passionnant et invite à la réflexion sur des sujets parfois clivants, notamment celui de la transition énergétique."--

International audience ; Echoing scientific and industrial progress, the Twentieth century was an unprecedented period of improvement for human capabilities and performances, with a significant increase in lifespan, adult height, and maximal physiological performance. Analyses of historical data show a major slow down occurring in the most recent years. This triggered large and passionate debates in the academic scene within multiple disciplines; as such an observation could be interpreted as our upper biological limits. Such a new phase of human history may be related to structural and functional limits determined by long term evolutionary constraints, and the interaction between complex systems and their environment. In this interdisciplinary approach, we call into question the validity of subsequent forecasts and projections through innovative and related biomarkers such as sport, lifespan, and height indicators. We set a theoretical framework based on biological and environmental relevance rather than using a typical single-variable forecasting approach. As demonstrated within the article, these new views will have major social, economical, and political implications.
