Classical musicians have affected climate change and conversations around climate change in many ways.
In 2016, pianist and composer Ludovico Einaudi performed his "Elegy for the Arctic" on a melting glacier in Norway (pictured above).
There's an orchestra in Paraguay whose members play music created out of literal trash from the dump on which their town is built.

Classical musicians have also promoted conversations around climate change more locally, such as a 2020 sound installation by Matthew Burtner that took place at Interlochen Arts Academy.
Join IPR's music director Amanda Sewell on Wednesday, July 6 at 6 p.m. for a lecture on the relationship between classical music and climate change.
The talk is offered as part of the new Garden Lecture Series at Interlochen Center for the Arts. It takes place outdoors in the R.B. Annis Botanical Lab on the campus of Interlochen.
It's free, but advanced registration is strongly recommended.
