Martin Kemp writes in Nature – Science in culture: Inventing an icon

Any public campaign benefits from having an iconic image — something that captures the essence of the message and engraves it indelibly on our memories. But it is almost impossible to predict which images will actually stick, so creating one on demand is extraordinarily difficult. …

Even so, finding an iconic image was one of the goals of a meeting, Changing the Climate, held in Oxford, UK, on 11 and 12 September. Researchers and practitioners of the visual, literary, musical and performing arts came together to publicize the predicted perils of climate change, and there was much talk about a memorable image that would encapsulate the initiative…

The data must come from the best science available, but the presentation for maximum impact is a matter of invention in art and design. Of the images produced by the scientists, one in particular seemed to have the potential to combine iconicity with complexity. This is the ‘Tipping Points Map’ devised by Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research in Germany and research director of the Tyndall Centre for Climate Change Research at the University of East Anglia, UK. This global map, shown here, outlines what Schellnhuber has identified as regions where the balance of particular systems has reached the critical point at which potentially irreversible change is imminent, or actually occurring.
