 Hello. I'm Clara Dessar, a senior scientist at NCAR and a creator of Sounding Climate. This exhibit lets you hear and see how climate has changed in the past and how it is expected to change in the future. Sounding Climate uses data from one of the best climate models in the world, a model built at NCAR. Touch the color bar to discover how the data are mapped to sound and color. For precipitation, marimbas convey a watery kind of sound. For temperature, we've used clarinets and for sea ice, we've used violins. Touch the map to pick a location. Press play to hear and see how the climate changes from 1920 to 2100. The top row of maps shows the human effect on climate and the bottom row shows the human effect and natural variations together. The graph at the bottom of the screen shows how precipitation, temperature, and sea ice change over time at the location you chose. Carbon dioxide levels are on the graph, too. You can stop the display at any time to freeze the maps and then press play to resume. Also, check out each on its own and explore how model simulations with slightly different starting points produce different patterns of natural variability. You can find out what will happen to Arctic sea ice and when it's likely to disappear. Now it's time for you to explore. Choose locations like your hometown or a place you like to visit. Change how fast to play the data and see if that changes your impressions. I also think it's powerful to just listen.
