Over the next four weeks, we are exploring Newstalk’s 20 most influential moments of the past two decades. Everyday, across the station, we’ll look back at an influential moment chosen by listeners.  Today, we want to talk about the growing threat posed by climate change in the last twenty years and the growth of campaigns around the issue - many spurred on by Swedish teenager Greta Thunberg.  Is it too late to act? Can we do anything now to save the planet?  Joining us to talk about that was Cara Augustenborg, Fellow in Environmental Policy at UCD and regular Newstalk Contributor.
