A seminal paper co-authored by Stanford biologist Liz Hadly is the inspiration for “Tomorrow,” a new documentary premiering this week at global climate talks in Paris. French actress Mélanie Laurent and her friend, Cyril Dion, launched the project after reading about the 2012 paper and its warnings that Earth is approaching a tipping point beyond which the planet’s climate and biodiversity will be radically and unalterably changed beyond anything humanity has known. 

Dion and Laurent, who stars in “By the Sea” with Angelina Jolie and Brad Pitt, set out to interview people around the world working on solutions to environmental challenges. The film opens with an interview of Hadly, a Woods senior fellow, and U.C. Berkeley professor Anthony Barnosky, Hadly’s husband and lead author on the paper. The documentary will be screened for delegates to the Paris climate talks, among other audiences.

Laurent and Dion were not the only ones moved to action by the 2012 paper. California Gov. Jerry Brown asked Hadly and Barnosky to compile a global scientific consensus statement with broad-brush solutions for challenges including climate change, loss of eco-diversity, extinctions, pollution, population growth and overconsumption of resources. Brown has since distributed the statement, which is signed by 520 scientists from 44 countries, to national and international leaders such as Chinese President Xi Jinping.

Hadly and Barnosky’s book related to the 2012 paper, “Tipping Point for Planet Earth,” was released in the United Kingdom this past summer, and will be published in the U.S. in April.

Hadly is the Paul S. and Billie Achilles Professor in Environmental Biology and senior vice provost for undergraduate education.
