Twedt sonifies climate data — basically, she makes iconic or meaningful data sets audible by translating each data point into a note. When CO2 rises on a graph curve, the notes react by becoming high and screechy. As sea ice disappears, one hand replicates the sound of its diminishment by dipping into the low register of a piano while the other replicates a twinkling pattern that replicates repeating, shifting seasons.
By using music's unique ability to imprint on the human brain, Twedt's result is a sonic map that can help us understand how climate change is upending our world, just by listening.
