Talk to our top creative people – writers, musicians, comedians even (especially them) and you find most are deeply concerned about the massive threats to environment. Last week we heard the concerns of marine scientist Ove Hoegh-Guldberg. This week one of Australia’s greatest young singers, Missy Higgins, tells Dr Jonica Newby how climate grief has been at the heart of her most recent songs. Don’t Look Down is a breathtaking example. Missy describes the emotions – and the science – that have inspired her. She comes from a scientifically-minded family and is struggling with the choices confronting most families in this turbulent, uncertain world.
