This research precisely focuses on four movies, which allow a study of the global warming catastrophes, throughout the consumer cinema : Soylent Green, by Richard Fleischer, The Day After Tomorrow, by Roland Emmerich, An Inconvenient Truth, by Davis Guggenheim, and Planet Earth, by Alastair Fothergill and Mark Linfield.Theses movies however belong to several types : science fiction, disaster, lecture, and documentary. To study how landscapes are represented in those movies shows a new mythology emerging on global warming, based on a specific representation of urban and rural landscapes. It shows how the fear of an overcrowded earth has become an empty planet, a no man’s land.
