 Building off the original Da Vinci bridge in Norway, Vebjørn used Leonardo's philosophy of encompassing all fields of research to use the project to discuss global warming.First he used ice to reinterpret and construct a new bridge during his expedition to Queen Maud Land in Antarctica.After that, in December of 2007, Vebjørn erected a temporary ice bridge to dramatize the melting glaciers of Antarctica due to climate change outside of the United Nations Plaza in New York.
