What will our world look like in 2030? Filmmakers Jon Cring, left, and Joe Murphy are making a short mockumentary — a humorous, pretend documentary — this summer in Voorheesville to bring home the effects of climate change: It’s a world where refugees are rampant, political rhetoric doesn’t square with reality, and kids have never seen a butterfly. In this week’s podcast, Cring and Murphy discuss their hopes to eventually make the mockumentary a feature-length film and also talk about a blog launched this spring, “How I Talked About Climate Change Today.” They believe individuals can make a difference: The Murphy family went solar and the Cringes bought a bidet to save on toilet paper.
