The Bristlecone’s Fate is a short and rather beautiful (if haunting) documentary film that looks at the looks at threat that global warming poses to California’s bristlecone pine trees, which are the oldest living things on the planet. “From their perch atop the White Mountains at California’s eastern edge, the bristlecones have survived as entire human civilizations have arisen and disappeared. But there’s a new threat to the bristlecone’s existence, a globe-spanning emanation more menacing than anything they’ve faced in thousands of years.” The short is based on “The Vanishing Groves,” an essay in Aeon Magazine by Ross Andersen that we encourage you to read.
