In Yosemite, old notes yield new insights on climate
Joseph Grinnell, the founding director of U.C. Berkeley's Museum of Vertebrate Zoology, was a fanatic about taking notes. Put it all down, he would say. You might not think it's important but someone may. 
Today, Grinnell's detailed, nearly century-old field notes about chipmunks and other small mammals in Yosemite National Park are revealing new insights about climate change in the Sierra Nevada, a subject I explore in an article in this Sunday's Bee.
