Sailboats and a floating dock lie on the dry, cracked dirt in a harbor at Lake Hefner in Oklahoma City during a 2011 drought.
We've seen what some of the effects of global warming look like: shrinking glaciers, extreme weather events, and rising sea levels. But what does global warming sound like?
University of Minnesota student Daniel Crawford created a tune titled "Song of Our Warming Planet" to try to create that sound. He took the yearly average global temperatures from the last 130 years from NASA’s Goddard Institute of Space Studies and translated each temperature into a musical note which he plays on the cello.
He joins the show today.
