Life in a Globalizing World This French-American collaboration, titled The Standing March, was exhibited on the façade of the National Assembly building in Paris during the United Nations–sponsored climate conference in December 2015, when world leaders gathered to negotiate an international deal to control climate change. Using cutting-edge technology, the creators projected a video of faces from around the world to remind the negotiators about the impact of global warming on ordinary people.
