Actor and environmental activist Leonardo DiCaprio recently pledged $7 million towards ocean conservation projects, was named a United Nations Messenger of Peace with a special focus on climate change, participated in the largest climate march in history, and delivered a powerful address at the UN Climate Summit. As if that wasn’t enough, his foundation is also a supporting partner of the Green World Rising short film series that focuses on the state of the climate and solutions to the climate crisis. The Tree Media-produced series is narrated by DiCaprio and the third out of four episodes has just been released online.

The series starts with the root of the climate crisis — the rise of fossil fuels that created modern society as we know it. “Carbon” advocates for a putting a price on carbon pollution to prevent a catastrophic warming of the planet of two degrees Celsius. In order to avoid this scenario, we cannot burn more than 500 gigatons of carbon into the atmosphere and the film explains why a carbon tax is the best way to keep these fossil fuels in the ground.

Episode two examines what runaway climate change could look like if a tipping point is reached that releases massive amounts of frozen methane into the atmosphere — a greenhouse gas that is 21 times more potent than carbon dioxide over a 100-year period. “Last Hours” looks at the sixth global warming-driven mass extinction currently underway with methane beginning to be released from the tundra.

The most recent episode is titled “Green World Rising” and shows how we can start to move off fossil fuels and power the world with 100 percent renewable energy. “Human ingenuity working alongside Earth’s natural systems is building a new world that is sustainable and self-reliant,” DiCaprio says in the film’s intro. “By harnessing the elements of the sun, wind and waters we can move away from our dependence on fossil fuels, decentralize and create a sustainable economy that will support our modern civilization long into the future.”

The film features Stanford University professor of civil and environmental engineering Mark Jacobson, who is leading The Solutions Project along with actor Mark Ruffalo and “Gasland” director Josh Fox with the goal of transitioning all 50 states to 100 percent renewables produced by wind, water and solar in a few decades.

The final episode, “Restoration,” according to the Green World Rising website, will discuss “how the earth’s natural ecosystems deal with climate and how we can work with nature to turn the tide.”

With this Tuesday’s elections coming up fast, the Green World Rising website also provides a handy guide to pressuring your politicians on climate change and clean energy. You can find out if your elected official denies climate change and get an environmental scorecard for House and Senate members from the League of Conservation Voters.
