Introducing: WHO'S GONNA SAVE US?
This isn't a podcast about how climate change is real – we've known that for a long time. And it's not another show about the devastation climate change is causing, or how we got here.Because we don't need to talk about the problem anymore. We know what's going on.This is a show about how much better things could be, and the people who are fighting to get us there.Reporters from the science team at ABC RN and triple j Hack have been travelling around the country to meet the people bringing about real change and coming up with authentic climate solutions.If we want to avoid a climate catastrophe … WHO'S GONNA SAVE US?
