Billy Barr lives a simple life. He enjoys tea, sitting by the fire and reading. He lives alone in a house he helped build in a remote Rocky Mountain location. But what really gets him going is the weather, and more specifically, the snowfall in his neck of the woods. So he started taking notes about it: every winter, twice a day for 40 years. These detailed snowfall notes have become a treasure trove for scientists studying climate change.
