Got a keen eye for backyard biology? By watching when the plants in your neighborhood begin to bloom, you can help scientists track the progress of climate change. Backyard phenologists with a yen for citizen science can head to Nature's Notebook or Project Budburst, two national networks that recruit volunteer nature-observers from around the country to keep track of their local signs of spring.
