In 2013, University of Minnesota undergrad Daniel Crawford worked with professor Scott St. George to map climate data to cello music, sonorously illustrating 1880 to 2012 climate change trends. As a next step in the project, they’ve composed a new piece of music for string quartets, defining both pace and place of the temperature changes in the Northern Hemisphere.

Above, performed by Julian Maddox, Jason Shu, Alastair Witherspoon and Nygel Witherspoon from the University of Minnesota’s School of Music, this is The sound of climate change from the Amazon to the Arctic.

Based on surface temperature analysis from NASA’s Goddard Institute for Space Studies, the composition “Planetary Bands, Warming World” uses music to create a visceral encounter with more than a century’s worth of weather data collected across the northern half of the planet. (The specific dataset used as the foundation of the composition was the Combined Land-Surface Air and Sea-Surface Water Temperature Anomalies Zonal annual means.)…

As Crawford explains in the video, “Each instrument represents a specific part of the Northern Hemisphere. The cello matches the temperature of the equatorial zone. The viola tracks the mid latitudes. The two violins separately follow temperatures in the high latitudes and in the arctic.” The pitch of each note is tuned to the average annual temperature in each region, so low notes represent cold years and high notes represent warm years.

And here’s the 2013 piece: A Song for Our Warming Planet.
