This three part series follows climate activist Greta Thunberg as she takes a year off school to explore the science of global warming and challenge world leaders, calling for action on climate change. In 2019 Greta set off on a year off school to embark upon a mission that would take her across the globe to demand world leaders meet their promises to try and limit global warming. With unique access, this series follows 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.

In the second programme Greta sets off to the annual World Economic Forum in Davos, Switzerland, which will be attended by US President Donald Trump and other world leaders, to call for action on climate change. Greta is demanding an immediate reduction in fossil fuel use – one of the main drivers of climate change. As she travels across Europe Greta explores what is preventing more rapid action to tackle global warming. She meets Polish miners who’ve lost their jobs and who fear that climate change policies will further decimate their industry and culture. In Davos she is frustrated by what she sees as a media obsession constantly pitting her against President Trump. Greta also travels to the UK, to see the prototype of a technology that aims to lower emissions from industry – by capturing carbon dioxide from factory emissions before it enters the atmosphere. She also meets with a figure who’s been an inspiration to her – Sir David Attenborough.
