Can you hear the Earth breathing?

In the 1950s, Charles Keeling started measuring carbon dioxide concentrations in the atmosphere at the Moana Loa Observatory in Hawaii. These measurements showed for the first time how the planet itself is breathing as forests in the Northern hemisphere grow leaves in the Spring absorbing CO2, then release it back into the atmosphere in the Fall when leaves drop off the trees. In this episode we talk about ‘Can you hear the Earth breathing?’ a composition and performance translates this climate data into sound, that brings to life these sustainability cycles and the natural (and un-natural) systems that lie beneath the production and absorption of carbon dioxide. The performance includes both sonified data representing CO2 concentration along with field recordings, modular synthesizers, samplers, biofeedback pads connected to plants, FX pedals, and looping feedback. We talk with Lisa the data artist on the project as well as Erbse, a movement artist collaborating on the project and discuss data sonification, translating sustainability concepts and data for audiences, creating space for improvisation, decentering the human, and more.
