This week The Art Assignment tackles the intersection of art and our changing climate. Throughout history, art has helped reveal the climate around us and highlight our fragile relationship to it. The Art Assignment looks at navigational charts from the Marshall Islands, Katsushika Hokusai’s "Under the Wave off Kanagawa", Pieter Bruegel the Elder’s "Hunters in the Snow," Mali's Great Mosque of Djenné, the Ise Shrine in Japan, steadily sinking Venice, the cave paintings of Lascaux, and Robert Smithson's Spiral Jetty, among others.
