Gunn Memorial Library in Washington will present a screening of “Before the Flood” March 2 at 6 p.m.

The new National Geographic documentary film featuring Leonardo DiCaprio focuses on climate change.

A snow date of March 9 is planned at the Wykeham Road library.

The screening is sponsored by the Washington Environmental Council.

“Before the Flood,” by filmmaker Fischer Stevens and executive producer Martin Scorsese, follows DiCaprio as he travels to five continents and the Arctic, speaking to scientists, world leaders, activists and local residents to investigate concrete solutions to climate change and gain a deeper understanding of this complex issue.

The film presents an account of how society can prevent the demise, due to climate change, of endangered species, ecosystems and native communities across the globe.

DiCaprio interviews individuals from every face of society in both developing and developed nations who provide impassioned and pragmatic views on what must be done today to transition our economic and political systems into environmentally friendly institutions.

It includes interviews with former U.S. Presidents Barack Obama and Bill Clinton, former U.S. Secretary of State John Kerry, U.N. Secretary-General Ban Ki-Moon and Pope Francis, as well as top NASA researchers, forest conservationists, scientists, community leaders and activists.

The film is rated PG and runs for 96 minutes.

Following the screening, the audience will have the opportunity to engage in a discussion on climate change with members of the Washington Environmental Council.
