The snow guardian (2016)

For 40 years, billy barr has lived alone in small cabin in one of the coldest places in the United States – the ghost town of Gothic, CO. With no goals of proving anything, or even knowledge that the climate was changing, billy started collecting data about snowpack to pass the time in his isolated part of the world. When climate researchers at the Gothic-based Rocky Mountain Biological Lab discovered billy’s decades of detailed records, they uncovered clear and compelling evidence of climate change. As someone who has had to learn to survive in such a harsh environment, billy shares some advice about how to move forward on our changing planet.
