Daniel Crawford (email) decided to use his cello to communicate climate science by using data sonification to create "A Song of Our Warming Planet."
During an internship, geography professor Scott St. George asked Crawford about the possibility of turning into music a set of data on surface temperature data from NASA’s Goddard Institute of Space Studies.
With the coldest year on record (–0.47 °C in 1909) set to the lowest note on the cello (open C) each ascending halftone is equal to roughly 0.03°C of planetary warming and each note represents a year, in order from 1880 to 2012.
As the sequence approaches the present, the cello reaches higher and higher notes, reflecting the string of warm years in the 1990s and 2000s. The video ends with a stark message:
Scientists predict the planet will warm by another 1.8 degrees Celsius (3.2 degrees Fahrenheit) by the end of this century. This additional warming would produce a series of notes beyond the range of human hearing.As Jess Zimmerman (twitter), wrote for GristList July 1,
