Follow Greta over an extraordinary year in which she comes of age as she takes her fight against climate change to a global stage. But when Covid-19 brings life to a standstill Greta is faced with an even bigger challenge – to convince a world reeling from one crisis finally to face another.
As she travels across the globe, Greta explores the science - from the melting glaciers of Canada to the coal mines of Europe. She witnesses first-hand the consequences of climate change and makes clear the reasons why she thinks something must be done right now. On her journey, she meets climate scientists and confronts the complexity of what is required to make change happen. Encounters with some of the world’s leading scientists and economists allow the series to examine what the latest science tells us about what can be done to avert the worst effects of climate change.
