Premieres in its entirety as a special presentation on Earth Day

Greta Thunberg is on a mission to save the world. She is asking every one of us to act and to mobilize in order to slow down the growing climate change that is destroying our planet and threatens our way of life.

The message is clear, and scientists agree—we need to keep global temperature rise below 1.5 degrees in order to give our species the best possible chance of avoiding a catastrophic future.

This revealing series follows Greta as she steps from behind the podium and onto the front lines. Over the course of the three episodes, Greta explores the science as she travels to extraordinary locations across the globe, meeting leading climate scientists, witnessing first hand the consequences of climate change and confronting the complexity of what is required to make change happen.


The series follows Greta on her year off school to better understand the impact of global warming and discover what could help to reduce emissions.

She travels from the burning tar sands of the Canadian oil industry to the coal mines of Europe and the melting glaciers of the U.S. — places where the impact of a changing climate is glaringly obvious, both for the planet and for the inevitable human costs—making clear the reasons why scientists call for action to be taken.

The series also hears from a range of academics, economists and experts, further exploring the climate change science Greta encounters on the ground.

In the fall of 2019, then-16-year-old Greta took a year off from school to embark on an international mission to spread her message: that we must act to drastically reduce our carbon emissions — immediately.

Greta and Svante's Atlantic Crossing

Greta and Svante sail across the Atlantic Ocean battling turbulent tropical storms to reach the UN climate conference in Madrid. Scientists explain why storms are becoming worse due to global warming and what other effects increased carbon emissions are having on ocean life.

The world was transfixed as this teenager spoke with directness and clarity to power, from diplomats at the United Nations to the world’s economic elite at Davos. However, just as her journey was gaining serious momentum, a new threat emerged, and everything became uncertain.

The COVID-19 pandemic brought the world to a terrifying standstill when the global economy, modern society and Greta’s journey all came to a halt. However, as days turned to months and people around the world were confined to their homes, an unintended consequence of the COVID-19 pandemic resulted in the ongoing global shutdown, revealing how much we can lessen our impact on the planet if we radically change our behavior.

Episode 1 premieres Thurs., April 22 at 8 p.m. on KPBS 2 + Wed., April 28 at 8 p.m. on KPBS TV - Follow Greta as she sees impacts of climate change at three locations: melting glaciers and dying trees in Canada, and fire devastation in California. When a UN conference moves to Madrid, she sails across the ocean during life-threatening storms.

Athabasca Glacier

Greta joins Professor John Pomeroy and his team who have been studying the Athabasca Glacier. Greta learns that rising temperatures as well as soot from forest fires have caused the glacier to melt faster than the models suggest.

Episode 2 premieres Thurs., April 22 at 9 p.m. on KPBS 2 + Wed., May 5 at 8 p.m. on KPBS TV - Follow Greta's journey from the World Economic Forum in Davos, Switzerland, to Poland, where she speaks with miners who have lost their jobs. She also visits the UK, where she meets with one of her inspirations - Sir David Attenborough.

Reindeer Face Starvation

Greta meets indigenous Sami herders in Jokkmokk, Sweden. Greta learns that the change in climate is threatening their way of life. The Sami herders have been following reindeers for thousands of years but the reindeer are facing starvation due to rising temperatures. Scientists explain the effects that climate change is having on human migration globally.

Episode 3 premieres Thurs., April 22 at 10 p.m. on KPBS 2 + Wed., May 12 at 8 p.m. on KPB TV - Join Greta in Switzerland and Denmark to investigate potential solutions to limit climate change. She also explores how everyone can play a role, from what we eat to what we wear. Finally, she looks for lessons from the world's response to COVID-19.

COVID-19's Impact on Climate

Greta speaks to Dr. Jenny Stavrakou who has been measuring carbon emissions during the COVID-19 crisis. Greta learns that emissions dropped substantially during the crisis but have risen again.
